=+15-8.

A refrigeration system using the compressor described in Fig. 15-7 is designed to operate with a condensing temperature of 115 F with an evaporating temperature of 50 F when the outdoor ambient is 95 F. After the system is put into operation, the evaporator pressure is measured to be 69 psia, and the power to the compressor is 12 kW. Superheat and subcooling are assumed to be as given in Fig. 15-7, and the ambient is about 95 F.

(a) Estimate the condensing and evaporating temperatures,

(b) compare the actual and expected performance, and

(c) suggest
