Abstract

A freezing device where the temperature etc. in a storage room can be measured by using a measurement hole without affecting an installation environment. The freezing device (1) has a low temperature side refrigerant circuit (38) constructed from a compressor (20), an evaporation pipe (62), etc. and cools the storage room (4), formed in an heat insulation box body (2) by using the evaporation pipe (62), down to extreme cold temperature. A machine room (3) is provided beside the heat insulation box body (2) and has the compressor (20) etc. installed in it. The measurement hole (19) communicating with the inside of the storage room (4) is formed in the side wall on the machine room (3) side of the heat insulation box body (2).

Description

technical field [0001] The present invention relates to a refrigerating device, which is provided with a refrigerant circuit composed of a compressor, an evaporator, etc., and cools a storage room formed in a heat-insulated box to an ultra-low temperature through the evaporator. Background technique [0002] Conventionally, a freezer that maintains the interior of the refrigerator at an ultra-low temperature has a main body composed of a heat-insulating box. In the storage room, for example, an ultra-low temperature space of -80° C. or lower is formed by a freezer of a binary freezing system (refer to Patent Document 1). [0003] Usually, a freezer that maintains a storage room at an ultra-low temperature of -80°C or below is composed of an insulated box with an opening on the top and an insulated cabinet door that closes the top opening in a freely openable and closed manner, and is formed on the side of the insulated box. There is a mechanical room equipped with a binary ...
