Technical field
This application involves the anti-freeze technical fields of air-conditioner set, and in particular to a kind of water pump anti-freeze dress of air-conditioner set
It sets, anti-freeze water pump and air-conditioner set.
Background technique
During air-conditioning internal machine opens heating mode, outdoor machine of air-conditioner heat exchanger is in heat absorption state, it is meant that air-conditioning
Outer machine heat exchanger temperature is lower than temperature, if temperature is down to zero hereinafter, condensed water will build-up ice.Always in heating mould
Formula operation will result in buildup, and at this time heat exchanger surface will cover a thick layer ice, seriously affects outdoor machine of air-conditioner and changes
The heat exchange function of hot device.Heat exchanger is damaged to avoid ice cube from excessively accumulating, running pipeline ice defrost pattern is wanted after a period of time.
So operation a period of time heating mode will being ice for some time when outdoor machine of air-conditioner is when temperature is lower than 0 DEG C
White mode.
During changing ice defrost pattern, the ice cube on heat exchanger, which can melt, generates a large amount of water, can be with using water pump
(cannot directly arrange down in the condensed water of some countries, outdoor machine of air-conditioner) is discharged in water.Water pump is former using centrifugal pump
To pump function due to this water pump adapts to subzero 30 degree unaffected because being, and due to running using centrifugal impeller
Impeller does not rub with spiral case in journey, and which greatly enhances the service lifes of water pump.
In the related technology, outdoor machine of air-conditioner due to environment temperature be outdoor temperature, reach subzero ten several years very in air themperature
To being under conditions of twenties degree, water pump mouth condensed water is by easy icing and freezes water pump vane.If unit is changing ice defrost
Shutdown, water pump stop working suddenly in the process, and the water after thawing will flow to water pump mouth, freeze again.Water pump mouth is in liquid level at this time
Hereinafter, water pump vane, which protrudes into liquid level or less, will partially be frozen in, booting will be unable to starting water pump again, or even cause water pump stuck
The case where burning out water pump.
