5. economically and efficiently This process must be able to withstand continuous repetition without loss of refrigerant over an extended period The most common system used in the vending industry is the vapor compression or simple compression cycle system It consists of four basic elements an evaporator a compressor a condenser and a pressure reducing restricted all part of a sealed system The compression system operates at two pressure levels the low evaporating pressure and the high condensing pressure The refrigerant acts as the transport medium in which heat is moved from the evaporator to the condenser at the condenser the heat is dissipated into the surrounding air The liquid refrigerant changes from a liquid to a vapor and back to a liquid again This change of state allows the refrigerant to absorb and rapidly discharge large quantities of heat efficiently BASIC VAPOR COMPRESSION SYSTEM CYCLE DESCRIBED In the evaporator the liquid refrigerant vaporizes This change occurs at a temperature enough to absorb heat from the refrigerated space The temperature of vaporization is controlled by the pressure maintained in the evaporator the higher the pressure the higher the vaporization point The compressor pumps the vapor from the evaporator through the suction line and to the condenser The compressor takes the low pressure vapor and compresses it increasing both the pressure and the temperature The compressor pumps
