Abstract

The invention provides an air-conditioning heat exchange system comprising a high-efficiency evaporator, a high-efficiency condenser and a tubular heat exchanger, wherein high-efficiency condenser realizes integrated condensation and supercooling, the high-efficiency evaporator realizes integrated evaporation and overheating, and the tubular heat exchanger is employed to exchange heat with a gas coming out of the evaporator and a liquid from the condenser, and therefore, the heat of a refrigerating medium out of the condenser and the heat of a refrigerating medium out of the evaporator are utilized effectively and the efficiency of the system is improved; in the meantime, the overheating region and the evaporator region of the evaporator are communicated with each other through an overheating guide plate; the air-conditioning heat exchange system is simple in structure, and the sectional area of an overheating flow guide groove is approximately equal to the open area of overheating flow guide connectors at both ends so that the flow velocity of the refrigerating medium is stabilized at the guide plate, and as a result, the heat exchange efficiency is greatly improved.

Description

technical field [0001] The invention relates to a heat exchange system, in particular to an efficient heat exchange system used in the field of air conditioning, and belongs to the field of heat exchange of air conditioners. Background technique [0002] The common central air-conditioning system does not effectively recycle the heat of the liquid refrigerant from the condenser and the heat of the gas refrigerant from the outlet of the evaporator. [0003] Chinese patent document CN102095268A discloses a propane refrigerant air-conditioning device with a regenerator. The device is modified in the original air-conditioning system, and a regenerator is added. The regenerator has an inner tube communicating with the outlet of the condenser. The inlet of the pipe and the outlet of the inner pipe connected with the electronic expansion valve, the outlet of the expansion valve is connected with the inlet of the evaporator, the outlet of the evaporator is connected with the inlet o...
