Abstract
The proposed design describes a refrigeration system with an evaporator, which allows inherent absorption of heat from the ambient, a condenser returning refrigerant to a liquid state, a compressor delivering refrigerant within the system but with refrigerant flowing through a heat exchanger from the compressor to the receiver and flowing through such a heat exchanger parallel to the flow of low pressure gas leaving the evaporator in a vertical configuration which precludes the flow of liquid from the evaporator to the compressor but maintains the constant pressures and constant flow of refrigerant within the heat exchanger to maximize the efficiency of the system.
Claims5
A refrigeration system, comprising:
- a compressor;
- a condenser for transferring heat from high pressure refrigerant flowing therethrough to the surrounding ambient, said condenser having an inlet being in fluid communication with an outlet of said compressor through a first conduit;
- a heat exchanger for transferring heat from low pressure refrigerant flowing therethrough to high pressure refrigerant flowing therethrough, said heat exchanger having a high pressure inlet being in fluid communication with an outlet of said condenser through a second conduit;
- a receiver, said receiver having an inlet being in fluid communication with a high pressure outlet of said heat exchanger through a third conduit;
- an expansion valve having an inlet being in fluid communication with an outlet of said receiver through a fourth conduit;
- an evaporator for transferring heat from a refrigerated space to low pressure refrigerant flowing through said evaporator, said evaporator having an inlet being in fluid communication with an outlet of said expansion valve through a fifth conduit;
- an accumulator having an inlet being in fluid communication with an outlet of said evaporator through a sixth conduit;
- said heat exchanger having a low pressure inlet being in fluid communication with an outlet of said accumulator through a seventh conduit, said compressor having an inlet being in fluid communication with a low pressure outlet of said heat exchanger through an eighth conduit;
- wherein,
- high pressure refrigerant flowing through said heat exchanger from said high pressure inlet thereof to said low pressure outlet thereof is in ascending parallel flow relation to low pressure refrigerant flowing through said heat exchanger from said low pressure inlet thereof to said low pressure outlet thereof.
