SYSTEM FOR AIRCONDITIONING

摘要

PURPOSE: An air conditioning system is provided to reduce energy consumption by using evaporation gas of liquefied gas. CONSTITUTION: An air conditioning system (100) comprises a heat exchanger, a main cooling part, an auxiliary cooling part, and a control part. The heat exchanger comprises an evaporation path and a cooling part. Liquefied gas is evaporated in the evaporation path. The cooling path is cooled by a heat absorbing action generated when the gas is evaporated. The main cooling part comprises a heat absorber which allows the first refrigerant cooled in the heat exchanger to absorb heat. The auxiliary cooling part cools or heats the first refrigerant flowing to the heat absorber when the amount of heat absorbed in the heat absorber is insufficient or excessive. The control part controls the auxiliary cooling part and the amount of the first refrigerant heat-exchanging with the auxiliary cooling part by comparing the amount of heat absorbed in the heat absorber with the amount of heat to be absorbed.
