Abstract1: Using air as refrigerant in air conditioning systems has enormous advantages over conventional refrigerants, many of which have harmful environmental effects, and are flammable or toxic. However, using air for refrigeration in buildings has been held back by the perception of poor energy efficiency of air cycle systems. This paper reports on collaborative research by BRE and the University of Bristol to build an air cycle system for simultaneous heating and cooling in buildings, with lower overall energy consumption and environmental impact than conventional heating and refrigeration plant.
