THE HEAT PUMP AND REFRIGERATOR


Abstract

The use of electrical work for refrigeration and heating represents a significant component of the non-transportation domestic energy use. The thermodynamic efficiency of the devices used to produce the desired heating or cooling is, therefore, very important. Measurements are to be made of the "Coefficient of Performance" of a heat pump and a refrigerator that uses Freon-12 as the working fluid. Measurements will be made for different temperature differences between the hot and cold reservoirs, and for different Freon flow rates. These devices will be evaluated as sources of heating and cooling under different operating conditions.
