Abstract

The invention relates to a water pump anti-freezing device of an air conditioning unit and an anti-freezing water pump. The anti-freezing device comprises a heat exchange pipe, an air inlet pipe and an air outlet pipe, wherein the heat exchange pipe winds around a water pump, one end of the heat exchange pipe is connected with an exhaust end of a compressor of the air conditioning unit through theair inlet pipe, and the other end of the heat exchange pipe is connected with an air suction end of the compressor of the air conditioning unit through the air outlet pipe. The device can solve the problem that a water pump impeller is frozen in a low-temperature severe environment, the normal operation of an air conditioner heating mode is guaranteed, and water generated in a defrosting and deicing process can be effectively discharged in time; and a branch pipe flows through a water pump port from a high-temperature high-pressure part of a refrigerant circulation system, the internal energyof the air conditioning unit is well utilized, no extra heating unfreezing device is added, the structure of the air conditioning unit is slightly changed, the machining is simple, and the cost is low.

Description

technical field [0001] The present application relates to the technical field of anti-freezing of air-conditioning units, in particular to a water pump anti-freezing device and an anti-freezing water pump of an air-conditioning unit. Background technique [0002] When the air conditioner’s internal unit is in heating mode, the heat exchanger of the air conditioner’s external unit is in a heat-absorbing state, which means that the temperature of the air conditioner’s external unit heat exchanger is lower than the air temperature. If the air temperature drops below zero, condensed water will form. ice. Always running in the heating mode will cause ice cubes to accumulate. At this time, the surface of the heat exchanger will be covered with a thick layer of ice, which will seriously affect the heat exchange function of the heat exchanger of the air conditioner's external unit. In order to avoid damage to the heat exchanger due to excessive accumulation of ice cubes, run the de...
