Abstract
An apparatus includes a microchannel heat exchanger, a load, a compressor, and a controller. The microchannel heat exchanger removes heat from a refrigerant. The load uses the refrigerant to remove heat from a space proximate the load. The compressor compresses the refrigerant from the load. The controller determines a discharge temperature of the refrigerant at the compressor and predicts a saturation temperature of the refrigerant between the compressor and the microchannel heat exchanger. The controller also determines a discharge superheat by subtracting the saturation temperature from the discharge temperature and triggers an alarm if the discharge superheat is below a threshold temperature.
