Abstract
A method of controlling supply air temperature in an enclosure refrigerated with a refrigeration cycle including an evaporator exhibiting a temperature differential, is disclosed. The method includes the steps of defining a supply temperature limit constant and a setpoint; sensing supply air temperature; sensing return air temperature; comparing supply air temperature to the supply temperature limit constant; increasing supply air temperature if supply air temperature drops below the constant and at least one of additional determinable factors is sensed, thereby reducing cooling capacity; and increasing cooling capacity without substantially effecting the temperature differential at the evaporator.
