Abstract
PURPOSE: To provide a freezer capable of maintaining a proper refrigerant overheating degree to standard freezing load since a warmth sensing tube for detecting the temperature of the refrigerant at the outlet of an evaporator is provided along a high-pressure piping on the temperature type automatic expansion valve whose static overheating degree is increased.
CONSTITUTION: Numeral 4 denotes a temperature type automatic expansion valve provided in the refrigerant passage leading from a condenser 2 to an evaporator 5. A valve 7 is operated by the power F of a static overheating degree setting spring 8, the pressure Pb from a sensor tube that works on the upper and lower faces of a bellows 6, and the pressure Pl corresponding to evaporation pressure. Said spring power F is set larger than usual. Said warmth sensing tube 10 is set to generate a correspondingly high pressure thereto since heat is supplied from the high pressure refrigerant flowing in a high-pressure piping 11. When ambient temperature and discharge gas temperature rise, said warmth sensing tube 10 detects this to open said expansion valve. When ambient temperature lowers and load decreases, said expansion valve is throttled. Therefore, room cooling capacity can be adjusted automatically to correspond to load.
