Abstract
A refrigerant receiver of elongated pipe 4 shape arranged in front of a refrigerant condenser 3. The receiver is of a dimension matched to that of the condenser, and has an inlet 34 for connection with the condenser section 13 and an outlet 38 for connection with a supercooler section 14. The receiver has inclined pipe portions 35 and 37 having inclinations to the horizontal direction, between which a bent portion 36 is arranged. No bubble is created in the refrigerant in the receiver irrespective of large values of the inclination of the receiver, thereby allowing only the liquid phase refrigerant to flow into the supercooler 14 from the outlet of the receiver 4.
Claims7
A refrigerating apparatus comprising:
- a compressor for compressing a refrigerant;
- a condenser for condensing the refrigerant from the condenser;
- a receiver for receiving the refrigerant from the condenser;
- a pressure reducer for reduction of the pressure of the refrigerant from the receiver;
- an evaporator for evaporating the refrigerant from the pressure reducer;
- a recirculating line for connection of the compressor, the condenser, the receiver, the pressure reducer and the evaporator for obtaining a refrigerating circuit;
- said condenser defining spaced apart surfaces and being in contact with an air flow so that a heat exchange can take place between the air flow transverse to said surfaces and the refrigerant flowing in said condenser;
- said receiver being arranged adjacent to the surface of the condenser to which the air flow is introduced, the receiver being constructed as an elongated pipe having a refrigerant inlet and a refrigerant outlet, which is located at a position lower than that of the inlet end, and an intermediate pipe having portions included with respect to a horizontal direction and at least one bent portion between the inclined portions for obtaining a rapid change in the direction of the flow of the refrigerant in the receiver, and
- a supercooler for obtaining a heat exchange of the refrigerant with the air flow, said receiver being arranged between the condenser and the supercooler.
