The invention discloses a heat exchange structure and an air conditioning system. The heat exchange structure comprises an evaporator assembly, a condenser assembly, a cooling assembly and a compressor assembly, and the cooling assembly is used for reducing the temperature of the environment where the condenser assembly is located; the compressor assembly comprises at least two oil-free compressors, all the oil-free compressors are arranged in parallel, refrigerant outlets of all the oil-free compressors are converged to form a refrigerant outlet of the compressor assembly, and the refrigerantoutlet of the compressor assembly is communicated with a refrigerant inlet of the condenser assembly. And refrigerant inlets of the oil-free compressors are converged to form a refrigerant inlet of the compressor assembly, and the refrigerant inlet of the compressor assembly communicates with a refrigerant outlet of the evaporator assembly. According to the characteristics of the oil-free compressor, losses in the refrigerant conveying process can be reduced; meanwhile, the environment temperature of the environment where the condenser assembly is located is reduced through the cooling assembly, then the condensation temperature of a refrigerant in the condenser assembly is reduced, so that the compression efficiency of the oil-free compressor is further improved.
Description
technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to a heat exchange structure and an air conditioning system. Background technique [0002] The subway has become an indispensable means of transportation for modern people to travel. At present, the number of subways used is huge and is still expanding rapidly. An air-conditioning system is generally installed in the subway, and the temperature inside the subway is adjusted through the air-conditioning system to improve the comfort of passengers on the subway. [0003] Because the subway is generally narrow and long, the traditional subway air-conditioning system has the problems of large loss and low energy efficiency when it is in use, which affects the operation of the air-conditioning system. Contents of the invention [0004] Based on this, in view of the problems that the traditional subway air-conditioning system has large loss and low energy efficiency, w...
