Abstract
In a refrigeration system in the form of a refrigerant circulation circuit, a first valve is disposed within a bypass circuit of the circulation circuit for being opened to supply therethrough the hot gas outflowing from a compressor directly into an evaporator. A second valve is interposed between a condenser and the evaporator for being closed to prohibit flow of refrigerant from the condenser into the evaporator therethrough. A first relay is energized to open the second valve when a first detecting element detects finish in cooling of medium caused by thermal exchange with the evaporator. A second relay is energized to close the first valve when a second detecting element detects finish in vaporization of liquefied refrigerant accumulated within the evaporator during cooling of the medium.
