Refrigeration apparatus

Abstract

An object is to provide a refrigeration apparatus capable of measuring a temperature in a storage chamber or the like by use of a measurement hole without influencing an installation environment. A refrigeration apparatus 1 of the present invention includes a low-temperature-side refrigerant circuit 38 constituted of a compressor 20, an evaporation pipe 62 and the like, a storage chamber 4 constituted in an insulating box body 2 is cooled to an extremely low temperature by the evaporation pipe 62, the refrigeration apparatus further includes a mechanical chamber 3 which is constituted by the side of the insulating box body 2 and in which the compressor 20 and the like are installed, and a measurement hole 19 communicating with the inside of the storage chamber 4 is constituted in the side wall of the insulating box body 2 on a mechanical chamber 3 side.

1 . A refrigeration apparatus which includes a refrigerant circuit constituted of a compressor, an evaporator and the like and in which a storage chamber constituted in an insulating box body is cooled to an extremely low temperature by the evaporator, the apparatus comprising:
 a mechanical chamber which is constituted by the side of the insulating box body and in which the compressor and the like are installed, a measurement hole communicating with the inside of the storage chamber being constituted in a side wall of the insulating box body on the side of the mechanical chamber.   
   
   
       2 . The refrigeration apparatus according to  claim 1 , wherein the insulating box body is formed of a composite constitution of vacuum insulating panels and a foam insulating material, and the vacuum insulating panels are arranged in front and rear walls of the insulating box body and a side wall of the insulating box body on a side opposite to the mechanical chamber. 
   
   
       3 . The refrigeration apparatus according to  claim 1  or  2 , wherein the mechanical chamber is provided with an openable/closable panel which covers the measurement hole. 
   
   
       4 . The refrigeration apparatus according to  claim 3 , wherein a top panel of the mechanical chamber Is configured to open or close, and the measurement hole is operable in a state in which the top panel is opened.
