Domestic Air Source Project 2017

Winners: Viessmann and Matrix Energy Systems - exlusive property in Jersey
Matrix Energy Systems was asked to provide a heating solution for one of the most exclusive properties in Jersey. Because of the very specific requirements, they installed three Viessmann Vitocal air source heat pumps.

​One of the most exclusive properties in Jersey, Le Couperon is an £8m luxury home situated on the site of a converted Napoleonic fortress.

Matrix Energy Systems was asked to provide a heating solution for the main house’s considerable, 11,500 sq ft floor area, swimming pool, showers, and guest accommodation. The new heating system had to be strong, dependable, and precisely controllable in different parts of the house, exceptionally energy efficient, and environmentally friendly, with no use of fossil fuels. 

The optimum heating technology for this property was determined through a process of elimination. Biomass was ruled out as fuel would have to be imported, ground source heat pumps was excluded because of drilling limitations, and solar panels resisted because of their effect on the aesthetics of the building. 

The solution, for energy-efficiency and fossil fuel-free heating, was three Viessmann Vitocal air source heat pumps. Air source heat pumps are particularly suited to Jersey’s climate.

Domestic Ground Source ​Project of the Year 2017

Winners: Finn Geotherm - Weybourne Milly

The brief was to provide low maintenance heating and hot water for a picturesque 18th Century tower windmill used as a family home.

One of the key factors in the brief was to install a ground source system which needed little intervention from the homeowner. For Mrs Martin, who is in her 80s, the heating and hot water needed to virtually run itself. The building’s 18th Century structure provided many heating challenges. The existing oil boiler system was unable to deliver adequate heat throughout.

The entire system was designed and installed without impacting the aesthetic appearance of this truly remarkable home. The ground source heat pumps were installed within the existing oil tank storage space and 2,000 metres of collector loop were meticulously laid within six inch wide trenches at a depth of 1.2 metres within a field adjacent to the house. Primary trenches were carefully taken through the hedging and across the lawn, to leave virtually no trace after the installation was completed.

ACR Product of the Year 2017​

Winners: Samsung Electronics UK and Irl - Samsung 360

The new Samsung 360 Cassette is a world-first circular air conditioning unit with omnidirectional flow discharge.

In order to create this circular cassette, Samsung had to overcome the restrictions associated with oscillating louver blades used in traditional four-way cassettes – impossible to fit into a circular unit.

​In order to overcome this, Samsung developed a patented ‘negative pressure solution’. Using three mini booster fans, a negative pressure is formed on the upper side of the cassette, deflecting the air upwards. Speeding up and slowing down these fans oscillates the air in the same motion as would be created by a louver blade.

This lack of physical frictional blades increases the efficiency of the system and achieves a 0° discharge angle, allowing the air to pass along the ceiling and avoid cold draughts.

Non-Domestic Ground Source Project of the Year 2017

Winners: Finn Geotherm - RAGT glasshouse

RAGT’s initial brief was to reduce the heating costs for its six glasshouses, which are used for developing new crops. LPG had previously been used to heat the glasshouses which, with a U value of around six, meant the boiler was in constant use in winter, leading to issues with fuel supply and heat distribution as the system couldn’t keep up with the heat being generated.

RAGT needed a new system that was energy efficient, sustainable and could also be retrofitted to current equipment, including its existing grow tubes, and use the current plant room.

​This is the biggest heat pump installation that Finn Geotherm has undertaken to date, they specified and installed three Lämpöässä T120 ground source heat pumps linked to three Akvanti 2400 litre thermal stores.

A network of 21,000 metres of collector loop was meticulously installed, with each loop no more than 500 metres as recommended by Lämpöässä to minimise pumping energy losses via the series of manifold chambers..

In addition, each of the 42 loops was carefully modelled and nested in the trenches to ensure cold flows did not cross with warm returns and impact the system’s efficiency.

Non-Domestic Air Source ​Project of the Year 2017

Winners: Cool-Therm - Number 5, North Colonnade, Canary Wharf

This innovative replacement cooling and heating project in Canary Wharf has dramatically reduced building running costs and carbon emissions, while providing outstanding indoor comfort for occupants.

Energy costs have been reduced by some £255,027 a year, amounting to nearly £5,000 per week. These savings will continue to accrue over the anticipated 10 to 15 year operational life of the plant, delivering total lifetime savings of between £2.55m and £3.8m.

Designed and installed by Cool-­‐Therm in collaboration with Gratte Brothers and WSP London, the replacement system is based on all-­fresh air heating and cooling. This is supplied by high performance Air Handling Units (AHUs), with a combination of water-­ to-­air heat pumps and dx cooling.

Key to its efficiency is the harnessing of energy from condensing water from the cooling system for use in heating the building.

In addition, each of the 42 loops was carefully modelled and nested in the trenches to ensure cold flows did not cross with warm returns and impact the system’s efficiency.

Heat Pump Product of the Year 2017

Winners: Mitsubishi Electric Ecodan QUHZ Air Source Heat Pump

The Ecodan QUHZ air source heat pump is engineered to match the different heating and hot water requirements of new-build homes. The MCS-Approved unit uses CO2 as a refrigerant to ensure a large Delta T between flow and return temperatures and deliver the high levels of efficiency needed to meet the demands of today’s well insulated new houses.

The unit delivers water at 70ºC to a packaged 200 litre thermal store. From this thermal store, mains water is heated directly up to 65ºC via Mitsubishi Electric’s unique plate heat exchanger, meaning the homeowner receives hot water on demand.

Unlike other Ecodan models in the range, this unit uses CO2 as a refrigerant to ensure a large delta T between the flow and return temperatures to and from the outdoor unit, and this delivers the high levels of efficiency necessary to meet the high hot water, low heating demands of today’s new-build properties.

This takes the heat pump industry directly into a sector which has previously been dominated by gas.

Heat Pump Installer of the Year 2017

Winners: Ground Heat Installations

David Thompson, Managing Director and owner of Ground Heat, began working in the plumbing and heating industry as an apprentice in 1980.

In 2003, as Installations Manager at a plumbing and heating firm in Horwich, Bolton, he came across his first GSHP and never looked back.

His passion took him the length and the breadth of the country just to have the opportunity to install ground source heat pumps, as there were very few customers willing to take a risk with the new technology in the UK.

He began installing small domestic units and then moved on to large-scale commercial work in social housing units.

His most recent designs include installing 56 individual ground source heat pumps into a social housing unit in Bromley operated by a communal ground array and a unique riser design and the installation of an energy blade into a river in Clitheroe to run ground source heating.

RACHP Woman of the Year 2017

Winners: Jane Gartshore BSc FInstR, Director of Cool Concerns

Jane is very well respected and has an extremely high profile within the refrigeration industry. In her time she has served as President of the Institute of Refrigeration (IoR), chaired the IoR's Education and Training Committee, and is also on the British Refrigeration Association's (BRA) Council.

Jane's lead in sustainability issues throughout her career has made her a thought leader on subjects including energy efficiency, deploying natural refrigerants and reducing refrigerant leakage. Her international work includes working with UNEP to bring about the phase-out of CFC in developing countries.

She was recently included on the Daily Telegraph's 'Top 50 Women in Engineering' list. This is all in addition to her work as the well-respected co-owner of the consultancy and training firm, Cool Concerns.

Jane said: “I chose to study engineering at university on the advice of my (male) physics tutor. It seemed more interesting than teaching and more attainable than being an astronaut. My entry into the refrigeration industry in 1977 was purely because I was offered a graduate trainee position by a compressor manufacturer. I initially worked on the design and development of commercial RAC equipment and then moved into technical sales, a global troubleshooting role.”
