Description
The present invention relates to a cooling device provided with a refrigerant booster, and more particularly, to a refrigerant booster equipped with a refrigerant booster installed in a rear stage of a condenser to instantaneously increase a pressure of circulation through a through- And the cooling efficiency of the refrigerating booster is increased by increasing the expansion coefficient of the refrigerating booster.
As is well known, a general air conditioner is a well-known apparatus in which a refrigeration cycle is operated, and is a device that performs heat exchange by circulating a refrigerant by repeating four cycles of evaporation, compression, condensation, and expansion.
It is needless to say that the refrigerant is phase-changed while repeating the gas state and the liquid state for each cycle, but the entire refrigerant actually flowing does not change to the gas state or the liquid state but also exists in the mixed state of the liquid state and the vapor state. When the refrigeration cycle is operated in reverse, it becomes a heat pump, and the principle is the same principle as the cooling apparatus.
Efforts to increase its thermal efficiency in this refrigeration cycle have been and continue to be ongoing. For example, in order to increase the efficiency of the heat exchanger, a plurality of fins are installed on the outer surface of the refrigerant pipe in a heat exchanger having a simple shape of refrigerant tube, thereby generating a heat exchanger that maximizes the contact area with the outside air, come. This effort to increase the thermal efficiency is now almost reached the limit.
The performance of the air conditioner decreases with time as the cooling efficiency decreases due to the heat exchanger contamination, the compression loss due to the compressor wear, and the oil film and carbonized sludge due to the refrigerant flowing along the system.
Therefore, it becomes difficult to ensure the supercooling degree in the condenser. When the refrigerant which has not sufficiently liquefied progresses, the gas introduced together with the refrigerant interferes with the evaporation of the liquid, so that the expansion coefficient (temperature drop) The vicious cycle in which the ability drops again is repeated.
