In detail
FireChill’s entry level cooling device is the AC500, an industry-leading, efficient, robust unit ideally suited for the standalone, gas-fired provision of chilled water to supply air-conditioning systems.
Designed for outdoor use, a single unit can connect into the a/c system and deliver five refrigeration tons (5RT) or 17.5 kw of cooling, sufficient to chill a 250m² small grocery store or large residential unit. It operates at a Coefficient of Performance (CoP) of 0.68 and is at least 15% more efficient than its nearest competitor. FireChill systems are designed to work happily in ambient temperatures up to 50°C with manageable de-rating.
Scaling up with the MultiPack
As many as six FireChill AC500 units can be modularised into a FireChill MultiPack to deliver up to 105kw (30RT) of cooling capacity, sufficient to cool a 1,500m² small supermarket, data centre or a residential block. The MultiPack approach is more efficient than a single large capacity unit. Operating with multiple smaller units means that at each point of the part-load demand curve a number of individual smaller capacity units are working at their peak efficiency, thereby saving money and carbon emissions.
Follow the sun with zone control
FireChill’s cold water output can be easily directed by a thermostatically controlled valve to a zone demanding cooling. For example, a three zone layout could have one two ton air handler and two 1.5 ton air handlers (5RT in total), each with its own thermostat and each controlled to different temperatures. The other advantage of zoning is the capability to move cooling to areas of highest demand, so a traditional building cooling load calculation (say 25RT) based on square metreage, glass area, orientation to sun, can be reduced to 15RT with zoning by effectively moving the cooling around the building by “following the sun” and thereby reducing carbon emissions and saving money on energy and excess capacity.
