Compressor for refrigeratory equipment
A compressor for the refrigeratory equipment is provided. The compressor includes a casing having a compressing device mounted therein and a cooling pipe passing through the casing for cooling the compressing device.
The present invention relates to a refrigeratory equipment and its compressor. More particularly, the refrigeratory equipment can absorb and dissipate the mechanical heat produced by the compressor.
BACKGROUND OF THE INVENTIONThe conventional refrigeratory equipment comprises several components. In the compressor, the refrigerant is compressed and converted into a high pressure and high temperature gas. Once compressed, the hot refrigerant is then discharged into a condenser and converted into a low temperature liquid state. After that, the pressure of the liquid refrigerant is decreased and the liquid refrigerant is converted into the gas refrigerant by a pressure releaser which is usually a capillary or an expansion salve. When the refrigerant is cooled, it is then delivered into a evaporator wherein the evaporation of the refrigerant is the cause of the decrease of the temperature. For air conditioners, what exchanges heat energy with the evaporator is room air.
There are two major devices in the compressor. One is a electromotor and the other is a compressor drived by the electromotor. The reciprocating compressor uses a motor driven crankshaft to drive internal pistons. For the rotary compressor and the scroll compressor, the compression of the refrigerant is driven by a rotor in the compressor. However, frictional heat is generated in all these mechanical devices and the electromotor produces heat itself too. Although in the compressor heat energy is dispersed by the refrigerant which functions as the cooling fluid, the heat energy causes temperature of the gas refrigerant to rise even up to 150° C. Hence, more energy has to be consumed to condense the refrigerant after heat is absorbed at compressor, and therefore the efficiency of the compressor is quite low. Otherwise, though there is lubricant between the ring and rotor and in the bearing of the compressor and the electromotor, it absorbs heat when the compressor and the electromotor work. There is no specific heat sink for lubricant, so it has no way to disperse its heat energy.
Therefore, because of the defect in the prior art, the inventors provide a refrigeratory equipment and its compressor to effectively overcome the demerit that there is no way to disperse the mechanical heat generated in the compressor existing in the prior art.
