Abstract
In accordance with an embodiment of the invention, there is provided a method of warming a heat exchanger array of a very low temperature refrigeration system, the method comprising diverting at least a portion of refrigerant flow in the refrigeration system away from a refrigerant flow circuit used during very low temperature cooling operation of the refrigeration system, to effect warming of at least a portion of the heat exchanger array; and while diverting the at least a portion of refrigerant flow, preventing excessive refrigerant mass flow through a compressor of the refrigeration system.
