Abstract

In this work an experimental study for the vapor – compression refrigeration cycle has been performed under temperature range of 9.7-32°C. The effect of varying temperature on heat exchangers pressures, cooling capacity, net power consumption, and coefficient of performance COP are studied . The results indicated that condenser pressure, evaporator pressure, and power consumption increased with the increase of temperature. The data also indicated that cooling capacity increased as temperature increased until 15.6°C then after it decreased with further temperature increase. Also COP follow the same tread of cooling capacity.
