Abstract

PURPOSE: To provide the constant supply of dehumidified air by making a circulating cooling medium flow into a cooling medium compressor, the cooling medium being provided with cooling capacity to some extent, without allowing the medium vomited from an expansion valve to put itself to heat exchanging while detecting the overload of a refrigerator when it occurs.
CONSTITUTION: If a large amount of compressed air having high temperature and humidity flows into a refrigerating chamber B, causing the refrigerating load to go up abnormally, an electromagnetic valve N is closed by a pressure sensor S which detects the increased pressure on the vomiting side of the cooling medium compressor J. Since the cooling medium is supplied to a part of the passageway for the cooling medium b1 when the electromagnetic valve is closed, the heating surface area for heat exchanging becomes insufficient, and a slightly cooled cooling gas medium having cooling capacity to some extent as it has not been put to full heat exchanging is made to flow from the refrigerating chamber B, or the passage for the cooling medium b1 into the cooling medium compressor J. Therefore, even if the refrigerating load becomes overloard, the load of the cooling medium compressor J can go without overload, thus supply equipment to be used with dehumidified air at all times.
