The first step, refrigerator and air conditioner is made up of four large parts: compressor, condenser, expansion valve and vaporizer, can select the additional devices such as setting pressure controller, temperature controller, device for drying and filtering in the middle of needing according to control or use, but four large parts must be many.
Second step, after gaseous refrigerant is compressed into the gas of High Temperature High Pressure during work by compressor, enters condenser, and condenser is equivalent to a heat transmission equipment, the gaseous refrigerant heat exchange of High Temperature High Pressure is become the liquid refrigerant of cryogenic high pressure.
3rd step, liquid refrigerant passes through expansion valve again, so-called expansion valve is exactly a throttling arrangement, because the refrigeration agent flowing out expansion valve is contained, therefore out rear refrigerant pressure reduces, and temperature continues to decline, and (expansion valve of refrigerator generally replaces with capillary tube, because of from bassoon suddenly to tubule, the effect of throttling can be played equally) become gas-liquid two-phase.
4th step, then enter vaporizer, carry out heat exchange gasification in refrigeration agent revaporizer now, the gaseous refrigerant becoming high-temperature low-pressure gets back to compressor continuation circulation.
At present, for the refrigeration system of refrigerator, when ambient temperature is higher, compressor needs the amount of the refrigeration agent produced more, and compressor needs with larger Power operation, thus meet ambient temperature higher time compressor refrigerant the more demand of amount, but when the temperature of the surroundings is low, compressor only needs to produce a small amount of refrigeration agent, during compressor operating, do not need too large power just can meet ambient temperature lower time compressor refrigerant the less demand of amount.In prior art, in invariable frequency compressor, compressor only has a fixing rotating speed, if this fixing rotating speed is high rotating speed, then when ambient temperature is higher, compressor runs with this fixing high rotating speed, and meet the demand that refrigerating capacity is more, effect of compressor is higher; And when ambient temperature is lower, compressor only needs to keep lower rotating speed, meet the demand that refrigerating capacity is less, so, when ambient temperature is lower, compressor does not need larger power, but compressor still runs with high rotating speed, now effect of compressor is lower.
