Kitchen Air Conditioning System

A kitchen air-conditioning system comprises an air-conditioning assembly (1) and a range hood assembly (2). The air-conditioning assembly (1) comprises a compressor (11), an evaporator (12) and a condenser (13) which are connected with each other through a plurality of refrigerating medium pipes (14); the condenser (13) and the range hood assembly (2) are connected through a secondary refrigerant pipe (3), a heat dissipation unit (4) in communication with the secondary refrigerant pipe (3) is disposed on the range hood assembly (2). The secondary refrigerant pipe (3) on the condenser has a secondary refrigerant inlet and a secondary refrigerant outlet, and the secondary refrigerant in the secondary refrigerant pipe (3) can exchange heat with the refrigerating medium in the condenser (13), and the heat dissipation units (4) connected to the secondary refrigerant pipe (3) can quickly take away heat generated by the condenser.
