Abstract

A refrigerant system includes at least one compressor that compresses refrigerant and delivers it downstream to a heat rejection heat exchanger. The heat rejection heat exchanger is a microchannel heat exchanger. Refrigerant passes from the heat rejection heat exchanger downstream to an expansion device, from the expansion device through an evaporator, and from the evaporator back to the at least one compressor. A control operates at least one compressor and the expansion device to reduce pressure spikes at transient conditions.
