Air conditioner, cooling system of air conditioner and cooling method

Abstract

The invention provides an air conditioner, a cooling system of the air conditioner and a cooling method. The cooling system comprises a condenser (1), an evaporator (5), a compressor (6) and a frequency converter (2), wherein the condenser (1), the evaporator (5) and the compressor (6) are connected in sequence, and construct a loop; a refrigerant flow path is formed in the condenser (1); and a cooling flow path is formed in the frequency converter (2); and the cooling flow path is communicated with the refrigerant flow path in the condenser (1) through a liquid taking flow path, and is communicated with the cold evaporator (5) through a liquid return flow path. The cooling system provided by the invention is simple in structure, and has small influence on the overall structure of a unit; a refrigerant is prevented from being scaled and corroded in a pipeline of the cooling system; a refrigerant in the condenser is used for cooling the frequency converter, so that the influence of the external environment is small, and the cooling effect is stable and reliable; and the cooling of the frequency converter and the refrigerating function of the air conditioner are completed at the same time in one cooling system, so that normal running of the air conditioner is effectively ensured.

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 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 cooling water cooling, but air cooling is difficu...
