Abstract
A method for controlling temperature pulldown of an enclosure with a refrigeration system having a compressor, a heat rejecting heat exchanger, an expansion valve, and an evaporator comprises circulating a refrigerant through the refrigeration system, sensing a parameter of the enclosure, determining a desired evaporator pressure based upon the parameter sensed, and adjusting the expansion valve as a function of the desired evaporator pressure.
