Abstract: A central air-conditioning system, comprises a plurality of air-conditioning assemblies (1) and a plurality of range hood assemblies (2); each air-conditioning assembly (1) comprises a compressor (11), a first heat exchanger (12) and a second heat exchanger (13) which are connected with each other through refrigerating medium pipes (14); all the range hood assemblies (2) are in communication with the public flue (6); a third heat exchanger (3) and the second heat exchanger (13) is connected through a secondary refrigerant channel (4); each end of each secondary refrigerant channel (4) respectively exchanges heat with the second heat exchanger (13) and the third heat exchanger (3).

Abstract: A kitchen air-conditioning system comprises a air-conditioning assembly and a range hood assembly; the air-conditioning assembly comprising a compressor, a first heat exchanger and a second heat exchanger which are connected with each other through a plurality of refrigerating medium pipes; and the air-conditioning assembly has a fresh air inlet and a fresh air outlet, the fresh air coming from the fresh air inlet is divided into two paths; the fresh air entering the first heat exchanger flows into the kitchen through the fresh air outlet, and the fresh air entering the air intake area cools the third heat exchanger in the range hood assembly and is then exhausted to the outside through the range hood, which is helpful to reduce the intake-air temperature of the second heat exchanger, thereby improving the energy efficiency of the air conditioner.
