Ed Whinyates of Stonegrove Refrigeration Services separates the fact from the fiction when it comes to choosing ammonia as your next refrigerant.
Ammonia refrigerant (also known as R717 and its chemical formula NH3) has been used as a refrigerant in industrial applications for more than 150 years. It offers a number of significant environmental and operational benefits with zero direct global warming potential (GWP) and zero ozone depleting potential (ODP).
A 960mm parapet wall almost halted plans to install air conditioning at luxury apartments in the redevelopment of a listed five-storey house in London’s Hyde Park.
Planning constraints meant that the heat recovery condensing units originally specified for the second, third and fourth floor apartments were too tall to go on the roof behind the parapet wall.
With air conditioning a key specification for the bedrooms and living areas, installers Hoveair (Building Services) recommended that the equipment specified manufacturer be changed to Daikin throughout the building.
