FIELD: refrigeration engineering. SUBSTANCE: device has compressor 1, condenser 2, receiver 3, throttle 4, and evaporator 5 which are connected in series and define a closed loop. Air duct 8 is constructed as hollow plastic cylinder whose top part is ended by diffuser 11 made of plastic. The wide part of the diffuser is exposed to the air flow from the axial fan. The diffuser is used for accelerating the air flow. A suction pipe line passes through the side of the air duct and along the diameter of the inlet section of it. The length of the suction duct is equal to the diameter of the cross-section of air duct 8. Rubber gaskets 10 are used for sealing the sites of passing of the suction pipe line 6 and for preventing breaking out of the suction pipe line due to possible vibrations of air duct 10. Suction pipe line 6 enclosed by air duct 8 is coated with material having unclosed pores, e.g. claydite, which is heated when air flows through it. The coating is made up as detachable ring inserts 9 inner diameter of which is equal to the diameter of suction pipe line 6 and secured to it by fastening yokes. EFFECT: improved protecting. 1 dwg
