The invention provides an air conditioner, and a cooling
system and a cooling method of a centrifugal unit
transducer in the air conditioner. The cooling
system comprises a condenser (3) and a
transducer (1), wherein a cooling
water flow path is arranged in the condenser (3), a cooling flow path is arranged in the
transducer (1), and the cooling flow path is connected with the cooling
water flow path in the condenser (3) through a water
inlet flow path (5) and a water outlet flow path (6). In the cooling
system, the condenser is directly connected with the transducer, the structure is simple, the
water flow path is shortened, cost is saved, and the overall structure of the unit is not influenced; an expansion valve is adopted to control using quantity of cooling water according to the actual temperature of the transducer, the
cooling effect of the transducer is stable and reliable and cannot be influenced by external conditions, normal operation of the whole unit is guaranteed, and simultaneously cooling water is saved; and by adopting the cooling system of the invention to carry out cooling, normal operation of the air conditioner is guaranteed on the premise of normal and stable operation of the transducer.
