Patent ID: 6938432

Claim:
A cooling apparatus comprising: a compressor, a condenser, an expansion device, and an evaporator, all connected to each other in this order by a piping line to form a refrigeration circuit, the compressor being constructed to compress a refrigerant in a gaseous phase before it is delivered to the condenser where a quantity of heat is removed from the refrigerant so as to change the refrigerant into a liquid phase or into a gas-liquid mixture, and the refrigerant being then fed to the evaporator through the expansion device and subsequently returned to the compressor, the cooling apparatus further comprising a heating section interposed between the evaporator and the compressor, wherein the refrigerant leaving the evaporator is still the gas-liquid mixture until heated by and completely gasified in the heating section, the cooling apparatus further comprising a regulator located between the evaporator and compressor for controlling flow rate or pressure between the evaporator and the compressor.
