Air conditioner, and cooling system and cooling method of centrifugal unit transducer in air conditioner

Abstract

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.

Description

technical field [0001] The invention relates to the field of air conditioning systems, in particular to an air conditioner, a cooling system and a cooling method for a frequency converter of a centrifugal unit in the air conditioner. Background technique [0002] The compressor is the heart of the frequency conversion air conditioner system. The speed of the compressor directly affects the efficiency of the air conditioner. The frequency converter is the control system used to control and adjust the speed of the compressor. Therefore, ensuring the normal operation of the frequency converter is the prerequisite for the stable operation of the frequency conversion air conditioner. . However, the frequency converter will generate heat when it is working, and as the motor speed increases, the heat generated will also continue to increase, which requires a reasonable method to solve the cooling problem of the frequency converter. Common cooling methods include air cooling and wa...
