Unico SDHV Cooling Technology Is A Clear Winner In Worcester Racecourse’s New Weighing Room

Superior Comfort

Worcester Racecourse Weighing Room

Installation background

Worcester Racecourse, part of Arena Racing Company (ARC), opened its new state of the art Weighing Room in June 2024. The facility provides a modern, energy efficient environment for jockeys to get changed, make their preparations for racing and spend some time relaxing. On the upper floor there is a canteen and social area, a physiotherapy studio and warm-up room. A Stewards’ Room for weighing-in and use by race officials, together with a TV Broadcast office are situated on the ground floor. Unico System’s Small Duct High Velocity (SDHV) cooling, heating and ventilation technology was specified to provide the perfect indoor environment all year round for everyone using the facilities.

Unico System is an all-in-one system that maximises the potential of heat pumps to offer air conditioning, heating, hot water and integration with mechanical ventilation and heat recovery systems (MVHR). The technology was specified for the Weighing Room as a versatile, practical and financially attractive alternative to a traditional fossil fuel-based HVAC system.

Its specification was the result of close collaboration between Worcester Racecourse & Arena Racing Company, Unico’s principal UK distributor Bell Plumbing and Unico Specialist Installation Partner, Butco of Sutton Coldfield. The overall cost and energy efficiency of the Unico System were not the only considerations and indeed sustainability was a key focus for the whole Weighing Room project. The steel frame building has been constructed on the site of the original weighing room and features a green living roof to tie in with the natural riverside landscape and provide biodiversity. Solar photo-voltaic panels capture the sun’s energy and convert it into electricity for the building.

The cooling capabilities of the Unico System were considered particularly important.  Throughout the summer racing season indoor temperatures within the weighing room complex can be uncomfortably high.  The ability to set draft free even temperatures, as well as providing precise instant cooling is a major benefit.

System Specifications

Two Air Source Heat Pumps (Vaillant aroTHERM Plus) located on the terrace outside the Weighing Room provide the renewable energy source for three separate Unico AHUs, sited in the Plant Room on the upper floor. One ground floor unit provides climate control within the male and female changing rooms through the Unico 3642 AHU whilst the Stewards Room and TV Broadcast office are served by a Unico 3036 AHU. The higher capacity third unit caters for the first floor canteen, rest/social area, warm-up and physiotherapy areas. The Unico 4860 AHU has a14-17.5 kW cooling capacity and 8.5-22.3 kW capacity for heating.

From the outset, installer Butco worked closely with Bell Plumbing’s Solutions team. They evaluated the project and subsequently proposed a truly value engineered HVAC solution that would mean significantly lower initial capital outlay and immediate lower running costs. It took into consideration the higher seasonal demand and virtually 24/7 usage of the Weighing Room over the National Hunt season as well as the projected significantly lower usage of the Weighing Room over the winter and early Spring.

Detailed calculations for heating, cooling and hot water demand were drawn up so that the most suitable and correctly sized Unico Air Handling Units and a combined MVHR unit, which would bring additional energy saving benefits of heat recovery, could be specified without any unnecessary over capacity.

Comprehensive schematic and working installation diagrams were generated with the latest CAD software by the solutions team at Bell Plumbing Supplies. Technical support was provided from start to finish of the project with Bell plumbing Supplies also addressing the evolving requirements and complexities of the project including revisions to room plans and usage. One of the challenges was how to incorporate the three Unico AHUs, the 2300m3 (Airflow Developments) MVHR unit and a (Mixergy) intelligent hot water cylinder as well as main supply ducting in the Plant Room, located in a tight area behind the canteen servery. There were significant height restrictions under the mono pitched roof, but thanks in part to the small footprint, compactness and horizontal configuration of the Unico AHUs, Bell Solutions were able to configure a layout that maximised use of the available space.

Solution

Two main central ducts, with Climaver thermal insulation for high efficiency and retention of energy within the system, lead from the AHUs and distribute conditioned air to multiple branches of Unico sound attenuated and insulated flexible supply tubing. Some 97% of system energy is retained and delivered into the conditioned spaces through room outlets. With the aspiration principle of operation, small jets of cooled or warmed air are driven at high velocity into the different areas of the Weighing Room with temperature differentials of no more than +/- 1º C floor to ceiling and no drafts. This creates an ideal environment and optimum comfort levels for all users in all areas of the building.

The lightweight, easy assembly central ductwork and the small diameter, flexible Unico supply tubing simplified installation for Butco.  The tubing could be cleverly fed above suspended ceilings and through small voids behind cavity/partition walls to all the ground and upper floor rooms, connecting with either linear or round room outlets.

Operating with extremely low noise levels (<30 decibels) and visually unobtrusive, the outlets blend into the interior decor of each room. Standard white finish linear outlets are used extensively in front of floor to ceiling windows and the canteen servery to form a conditioned air curtain that helps to keep room temperatures to desired preset levels. Round outlets have been carefully positioned around ceilings to ensure uniform delivery of conditioned air within each space, preventing hot or cold spots and maintaining a consistent temperature throughout. Indoor Air Quality levels throughout the building are also consistently high thanks to lower humidity levels and the ability of Unico technology to remove up to 30% more humidity than would be achievable with traditional air conditioning technology.

Ensuring compliance with the requirements of Building Regulations Part F (ventilation), Part L (energy efficiency) and Part O were essential requirements for the Unico proposal. Part O covers thermal efficiency, overheating and limiting solar gain through windows inside a building. The floor to ceiling windows and extensive glazing throughout the Weighing Room, coupled with the building’s high levels of insulation and overall air tightness, meant that overheating was a potential problem. This has been overcome through the levels of cooling provided by Unico.

Results

For Worcester Racecourse management, the ability to set temperatures for each area and control the complete Unico installation remotely from an office located in the Grandstand is very convenient. An iPad with Nest programming is a low cost and very user-friendly means of setting and adjusting preferred cooling and heating levels all year round. Three compatible wall mounted smart Nest Learning Thermostats have also been provided within different areas of the Weighing Room.

Opened in time for the very popular Ladies Day meeting on June 1, the Weighing Room is in use throughout the National Hunt racing season which ends in October, and it will also have usage over the winter months. Butco met the strict timelines put in place for completion of the installation, despite interruptions caused by repeated local flooding from the River Severn.

The installation at Worcester Racecourse has demonstrated that in the light commercial sector, Unico SDHV technology is a viable environmentally friendly alternative to traditional fossil fuel-based heating/air conditioning with a BMS system. James Tough, xxx (TBC) of Butco is positive about involvement in further Unico projects of this type: “With the support of Bell Solutions in assessing a potential project, designing the system as well as providing technical back up throughout the specification and installation process, we are confident in taking on further projects where Unico offers the best solution.”

Cliff Arnold, Bell Plumbing’s HVAC Technical Manager, comments: “We offer in-depth training and marketing support to any HVAC installer looking to get involved with Unico SDHV technology. They will then be able to give their residential and commercial customers the opportunity to consider and move to environmentally friendly heating and air conditioning systems at a time when significantly reducing carbon emissions from buildings is critical.”

Installation of the Unico System Small Duct High Velocity (SDHV) system in the reception area at NSBRC

NSBRC Entrance with Unico Installation

The National Self Build and Renovation Centre (NSBRC) is the country’s only permanent venue for independent homebuilding advice and showcases the best building technologies and construction methods. Since becoming an employee owned business in 2014, the facility has been continuously developed to ensure the optimum visitor experience for the 1000s of self-buiders, home improvers and building professionals who attend annually. The most recent initiative has been the installation of a new Unico System Small Duct High Velocity (SDHV) system in the reception area of the venue to welcome visitors with a comfortable indoor environment whatever the time of year or the weather outside.

NSBRC mock house

Air Craft, an indoor air comfort specialist and approved Specialist Partner for the Unico System, were responsible for the design and installation of the system.  Managing Director Darren Johnson believes that the all in one cooling and heating solution was the best technology to fulfil the requirements of the project. “ The beauty is Unico’s ability to provide cooling and heating from one compact  Air Handling Unit (AHU) and being able to match it with the latest environmentally friendly Air Source Heat Pump (ASHP) energy source. In the summer, the 100+ square metre reception area, with its full width glazing, can be affected by elevated temperatures especially when many visitors can congregate there to register. Then in colder months the space needs heat and Unico can deliver that too.” says Managing Director Darren Johnson.

The suspended ceiling above the reception had plenty of space for the installation of a Green Series Unico MB4260H Air Handling Unit (AHU). It features the latest Variable Speed Control high efficiency fan, which is up to 62% more energy efficient than standard fixed speed motors, and Smart Control Board to ensure precise airflow control, easy commissioning and diagnostics.

One of the major advantages of the Unico System is its ability to be adapted for operation with the latest heat pump technology or other energy sources.  In this case it uses a Heat Pump coil and a Daikin Heat Pump outdoor unit, using low environmental impact R32 refrigerant with significantly lower Global Warming Potential (GWP) compared with other refrigerants and A++ seasonal efficiency.

To ensure compatibility between the two technologies, Unico and Daikin cooperated to develop a customised control box interface.  Air Craft used their extensive experience to ensure the required loading and technical performance for the AHU and the ASHP were carefully matched.

Aside from ensuring optimum comfort levels all year round, the Unico System also had to meet a number of other specification criteria including low operational noise with minimal disturbance in the reception area, even temperatures and freedom from draughts as well as being a visually unobtrusive installation.

Cooled or heated air is delivered into the reception area through flexible supply tubing which culminates in thirty discreet small round outlets spaced equally across the reception ceiling.

The flow of air through the supply tubing and into the reception through the outlets generates minimal noise thanks to a sound attenuating construction with its nylon tube core wrapped with insulation which also helps to reduce thermal losses. With aspiration technology, once the heated or cooled air enters the space at high velocity it creates a draught free, even environment with minimal temperature fluctuations.

The system is controlled through a standard Daikin thermostatic control which is linked to the control box. “ Multiple traditional air conditioning units would have been a totally impractical solution, because of the number of units needed and the space required to mount them. The Daikin Altherma 3 Monobloc Air Source Heat Pump does not require an indoor unit ,” says Darren.

The installation was completed by Air Craft with minimal disruption in the day to day operation of the reception area. Following rigorous testing it was fully operational in time for the NSBRC’s series of open days in May 2022.

Previous issues within the property

Unico & Mid Devon Case Study damp mould

Property & occupants

  • Householders in this property type are more likely to be elderly and less mobile
  • Many householders have downsized to a smaller property, and with a lifetime of possessions means that space can be at a premium.  Radiators and panel heaters may become obstructed and this impedes heating and the flow of air within the property.
  • Costly and inefficient heating systems are less likely to be used.  This results in under heated, poorly ventilated properties that may be subject to damp and mould.
  • Householders often create conditions that are likely to cause issues., ie, don’t open windows, cook without lids, don’t close the door to the bathroom, hang wet washing by heaters, etc.

To meet these challenges, they turned to the Unico System.

Solution

Mid Devon District Council selected the Unico SDHV system based on its innovative design which delivers conditioned and enhanced indoor air quality.  The system integrates a humidistat controlled MEV and maintains an exchange of fresh air to the property.  The advantage of being able to locate the distribution system in the roof space.  The longer term operational benefits include the price point, the integration of known technologies (ASHP) and the potential for future installations to be delivered by the DLO.  The enhanced environmental controls maintain healthy households, reducing pressure on the local NHS and GP surgeries.  We also expect the system to be fundamental in helping with the reduction of disrepair claims as a result of damp and mould.

“If there were a Michelin rating for comfort, the Unico System would undoubtedly receive 3 stars”.

Jamie Oliver, of Britain’s Channel 4 documentary series “Jamie’s Kitchen”, began the Fifteen restaurant brand in 2002 with a flagship location in London. The name is derived from the celebrity chef’s apprenticeship program of training fifteen disadvantaged youth in the culinary arts and service management industries.

Unico System Fifteen Restaurant
Unico System Fifteen Restaurant Interior

Overview

Fifteen in Cornwall overlooks the beach at Watergate Bay on the north coast of the county of Cornwall, UK. The restaurant offers slick, traditional Italian cuisine with a Cornish twist. The location features a high, open ceiling design and casual-chic interior with murals of pastel-colored surf scenes adorning the walls.

The developers of the property were determined to create a visual style for this new location as unique as that of Mr. Oliver’s approach to food. While adamantly determined not to copy the “faux-industrial” look of exposed metal ducting that has become so common in commercial locales, they were committed to adding a heating and cooling system that could deliver superior comfort as well as disappear into the background.

To meet these challenges, they turned to the Unico System.

Strategy

The very features that make the Unico System attractive to the old home and custom home residential markets make it an optimal choice for commercial-built applications as well. The modular air handling equipment, smaller main trunk ducting and flexible supply ducting allow it to fit where conventional heating and cooling systems simply cannot.

Air handlers and the main ducting were situated outside of the main dining area and Unico System supply tubes were snaked through the sloped ceiling’s cavities to discharge conditioned air from the high side walls. The versatility of the Unico System’s terminating outlets allow it to fit seamlessly into Fifteen’s open design. Available in a slotted, 1-inch x 8-inch configuration, this version was chosen over the round 2-inch inner diameter option as it better blended with the interior’s distinctive murals.

Air distribution with the Unico System provides two additional benefits. Conditioned air gently circulates within the room’s existing air currents, eliminating the drafts that often create guest discomfort in restaurants. This gentle mixing also eliminates the phenomena of stratification (that is, alternating hot and cold spots) associated with conventional forced air systems, instead maintaining even temperatures throughout the dining room.

Results

Not only does the Unico System practically disappear within the interior design of Fifteen, but guests and staff alike are kept comfortable during the ever-changing seaside weather. Kitchens can be frightfully hot places in which to work but, due to the open design plan and the superiority of the Unico System’s air delivery method, staff have remarked that Fifteen’s kitchen is the most comfortable they’ve ever experienced.

On the other hand, with hard-to-see visual evidence, no drafts and even temperatures, guests are hardly aware of the heating and cooling system and are not distracted from enjoying a wonderful, healthy meal in a beautiful setting.

If there were a Michelin rating for comfort, the Unico System would undoubtedly receive 3 stars.

“To see a design on paper is one thing, to actually fit it in and not see it is another. The supply outlets fit seamlessly into the space and the response of the system is extremely quick and impressive.”

Rod Pyke

Background

The owners of this prestigious London property tasked their project manager to find the most discreet heating and cooling system which would not compromise the new interior and architectural features of this period property.

After researching “discreet air conditioning”, he discovered the Unico System which was perfect for this new living space.

During the full renovation, the ceiling was dropped slightly to allow access for the main ducts. This provided enough scope to design the system into an extremely challenging building.

Solution

Due to restraints in the building, the whole system was first designed and modelled in 3D to ensure every component would fit into the space.

Two 14kW Unico Systems were installed in the loft space with main ducts running to each of the four floors below. All supply outlets were plastered into the ceilings, leaving just discreet 50mm holes delivering the conditioned supply air.

Return air from the rooms was done through bespoke transfer grilles above the doors and returned to the Unico Systems via the central staircase.

Both Unico Systems are interfaced with Mitsubishi Electric heat pumps and controlled through the Crestron BMS System.

The Unico System provides the perfect heating and cooling solution for this high end residential property.

Background

Built in 1890 as the first officer’s quarters on the submarine base naval station, the Harry S. Truman Little White House in Key West, FL, has entertained presidents and dignitaries for more than 63 years, ever since President Truman established the property as his winter vacation home in 1946. Frequent visitors to the home include Thomas Edison, Edward Hayden, Harry S. Truman, John F. Kennedy, Jimmy Carter, Colin Powell and Bill Clinton. The home stands as a magnificent, historical piece of architecture that serves as a museum and, at times, receives government officials for meetings and dinners.

Maintaining the historical character of the home was instrumental in the restoration process. “More than 85 percent of the historic fabric remains intact, so it was very important that we select the right HVAC system to protect the structure, our original furnishings and documentary collections. That’s why we chose The Unico System of St. Louis,” said Bob Wolz, executive director of Truman House.

The home needed an HVAC system to protect the irreplaceable artifacts, and the conventional system installed in 1990 was not doing the job. The system allowed humidity to attack the museums’ items and did not cool the 9,000-square-foot home evenly. The contractor restoring the home, Refri Air, Inc. of Fort Lauderdale, recommended The Unico System as a perfect solution to this home’s heating and cooling needs.

Strategy

The installation of The Unico System took eight weeks to complete. The massive project involved outfitting the home with 300 feet of special 10-inch round PVC duct, installing custom flat and circular outlets in the floors and ceilings of the home and putting in the system itself. To allow flexibility to the cooling and heating of the home, the house is split in five zones with five air handling units and four UniChillers, completely self-contained air-to-water heat pump chillers that use chilled water circuit instead of refrigerant inside the house.

A traditional system would have required additional condensing units to achieve zoned cooling, whereas The Unico System allows individual UniChillers to work in a single area without the entire system running at full capacity. The duct was installed in the attic and the 18-inch crawl space under the home. To ensure the system was virtually undetectable, contractors ran electrical connections from the attic to the crawl space and out to the chiller plant area, hiding the ductwork with customised fittings.

Once the system was in place, a specially designed UTrap was connected to the air handling in the attic for 30 percent more humidity removal throughout the home. This extra piece was a necessity to ensure all important items present in the museum would be protected for years to come.

Solution

The Harry S. Truman Little White House presented a unique set of challenges that were met with the installation of The Unico System. “The uniform temperature throughout the house is pleasant to guests and staff and protective for our artifacts,” said Wolz. The new Unico System gives peace of mind to historians and visitors alike, who can be assured that the home, which has stood for 120 years, will remain a place to enjoy historical ambience and objects in a cool, comfortable setting.

“Simple comfort, great value” might easily extend itself to the Unico System as well.”.

John Hearn, Head of Property Development for the easyHotel on Old Street in Barbican, had a problem: “The existing conventional ducted air systems were not able to accurately control temperature and we started getting complaints from our guests.” Quite a problem, indeed, when your motto is ‘’simple comfort, great value.”

Unico System easyhotel
Unico System easyhotel

Overview

easyHotel Group positions its properties as “super budget hotels,” maintaining inexpensive room rates by asking guests to sacrifice a little luxury space by offering smaller-sized rooms. easyHotels offer no frills – no on-site restaurants, bars, gyms, business centers or the like – allowing management and staff to focus on the maintenance and cleanliness of their utilitarian-yet-elegant accommodations.

Indoor climate control is a key factor to guest comfort. Two of easyHotel’s London locations, the flagship hotel in South Kensington and the Old Street site, use the Unico System to supply heating and cooling to their guests. The Unico System’s small duct attributes are especially suited to the budget hotel chain’s needs.

Strategy

Smaller rooms means smaller areas in which to house mechanical systems. In contrast to the bulky, rigid ducting required by conventional indoor systems, the Unico System’s main trunk line takes up one-third the space of traditional systems and its flexible 2-inch inner diameter supply tubing snakes through wall cavities, allowing conditioned air to be delivered specifically where it’s needed. Additionally, round Unico System outlets are smaller, more aesthetically pleasing and less noticeable than conventional grilles. They deliver quiet, draft-free indoor comfort – the guests don’t even know that they are there.

After a thorough evaluation of the Barbican site, installing contractor KBS Services removed the existing air handling, condensing units and controls and replaced them with eight Unico Systems with zone control to deliver indoor comfort to the hotel’s three floors and 95 rooms.

Similarly, the Unico System’s low profile made it the optimal choice for the concern’s first London venture in Kensington. The hotel in Lexham Gardens features 34 rooms within 5 floors of a converted row house, and installer HVAC Group of London recommended the Unico System specifically due to its smaller size and ability to provide superior comfort.

Results

easyHotel South Kensington’s Roger Powell states, “We needed the best for our customers within very tight budgets. The Unico System has given us just that – the best comfort solution and real cost savings over conventional systems.” The use of heat pump technology coupled with the Unico Systems’ long life expectancy also provides significant life-cost savings. Adds Mr. Powell, “The system also gave us the ability to ventilate effectively without employing a separate system” further reducing costs.

At the Old Street location, Mr. Hearn notes that the complete reconfiguration of control strategy through new thermostats and multiple temperature sensors “allows zone temperatures to be controlled by hotel management and [we] typically maintain a constant temperature of 72°F in each room” completely eliminating guest complaints.

“Simple comfort, great value” might easily extend itself to the Unico System as well.
