Abstract

The invention provides an air conditioner and a control method thereof. The air conditioner includes a motor, a refrigeration system, a refrigerant cooling heat exchanger, and a water cooling system.The refrigeration system includes a compressor, a condenser, a throttling device, and an evaporator which are arranged in sequence. The motor is provided with a shell, and the air conditioner is internally provided with a water storage structure. The refrigerant cooling heat exchanger is connected between the throttling device and the compressor, the water cooling system includes a water pump anda water cooling heat exchanger which are arranged in sequence, and an inlet of the water cooling system is arranged on the water storage structure. The refrigerant cooling heat exchanger and water cooling heat exchanger are coiled on the shell. The air conditioner further includes a switch device arranged between the throttling device and the refrigerant cooling heat exchanger. The control methodof the air conditioner includes the step of controlling the switch device and / or the water pump according to preset conditions. The motor in different states can be subjected to cooling heat dissipation through independent use or combined use of refrigerant cooling and water cooling, so that the problem of motor temperature rise is effectively solved, and the technical problem of limited motor rotating speed is further solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method thereof. Background technique [0002] Existing air conditioners include a motor in addition to a refrigeration system made up of a compressor, a condenser, a throttling device and an evaporator. After the motor is used for a long time, the temperature of the motor will rise. If the heat cannot be eliminated, it will shorten the life of the motor and even cause failure. In addition, since the standard has requirements on the temperature rise of the motor, the speed of the motor will also be limited. [0003] An existing means to solve the temperature rise of the motor is to arrange a multi-tooth cooling ring on the outer periphery of the motor casing, and the heat generated by the motor is sequentially transferred to the motor casing, the body of the cooling ring and the cooling teeth on the cooling ring to expand the heat transfe...
