Document Type and Number:
WIPO Patent Application WO/2020/183443
Kind Code:
A1
Abstract:
Provided are: a heat pump for refrigeration equipment, said heat pump being capable of rapidly cooling antifreeze for refrigeration equipment to an ultra-low temperature region of -40°C or less without causing oil in the heat pump to run out; and a rapid liquid freezing device using the heat pump for refrigeration equipment. This heat pump for refrigeration equipment comprises an evaporator, compressor and condenser that are connected as a coolant circuit, is configured so that heat cooled by the evaporator is released by the condenser, and is provided with a pressure regulation and bypass control means for compensating for a pressure drop when the pressure of refrigerant sent from the evaporator to the compressor drops.
