Performance curves have been obtained for condenser heat output, evaporator heat input and overall coefficient of performance (COP) as a function of outdoor air temperatures ranging from 10/sup 0/F to 50/sup 0/F and at an indoor air temperature of 65/sup 0/F. Both temperatures were controlled by recycling cold air from the evaporator exhaust and mixing it in the plenum. There is good agreement, within expected error bands, with available performance data for the York heat pump. In addition, this data has been used to obtain air side heat transfer coefficients ranging from about 9 to 6 BTU/hr/sup 0/F for the evaporator and 1.5 to 2.5 BTU/hr/sup 0/F for the condensor. These values are being used as a basis for the design of the fluidized bed heat exchanger. Plans for a separate test of the deicing capability of low temperature fluidized beds have been formulated.
