29. ATION PRINCIPLES A refrigeration system is principally involved in the process of transferring heat Heat is removed from the vending product area of the cabinet and is transferred to the condenser where it is dissipated With vending equipment large quantities of heat must be transferred economically and efficiently in a continuous fashion without loss of refrigeration gas over a long period of time The most common type of refrigeration system in vending is the vapor compression or simple compression cycle system This system consists primarily of three elements a compressor an evaporator and a condenser joined together as a sealed system In the vapor compression system there are two pressures present Low evaporating pressure and high condensing pressure The refrigerant gas acts as the transport medium in which heat is transferred from the evaporator to the condenser where heat is dissipated into ambient air A change of state occurs as the refrigerant changes from liquid to vapor and back to liquid again allowing the refrigerant to absorb and discharge large quantities of heat in an efficient manner The basic vapor compression cycle occurs as follows In the evaporator the refrigerant boils evaporates to vapor at a temperature sufficiently low enough to absorb heat from the cabinet space being cooled The pressure maintained in the evaporator controls the boiling temperature The higher the pressure the higher the boili
