Required Conditions for Optional Operation of an Air- Conditioning System

Abstract

The paper discusses two aspects of refrigeration systems based on mechanical compression used for air conditioning: first the subcooling in relation to the refrigerant charge and liquid-line temperature, and second the evaporator-leaving air temperature as a function of the fan-speed and of the entering temperatures (dry-bulb and wet-bulb). Both conditions are of importance for the proper operation of air conditioning systems and the analytical interpretation is given in a simple form of relationships.
