Favor.But its frosting problem is the principal element normally heated in influence heat pump unit winter, especially in cold northern area
With the south of high humidity cold, the development of air source heat pump seriously restrict.
Has a large amount of research to air source heat pump defrosting both at home and abroad, common Defrost method has reverse cycle defrosting and hot gas
Bypass defrosting two kinds, but the equal big energy-consuming of both Defrost methods and defrost when influence heating effect, so being required to subtract as possible
The control Defrost method for the frequency that defrosts less；Existing control Defrost method mostly uses timing control preparation method or single temperature method, timing
Control methods defrost within the corresponding time, and drawback, which is unnecessary defrosting operation, can cause unnecessary waste；It is single
One temperature method is exactly the surface temperature for detecting finned tube with temperature sensor, is set for defrosting according to temperature, still
Once temperature sensor damages, it is just also easy to produce maloperation；And either timing control preparation method or single temperature method, often in frosting
After very thick, just start control defrosting, inevitably defrosting is difficult, and defrosting time is long, is adversely affected to heating effect；And it ties
It begins to defrost when white seldom, then big energy-consuming, weight is born to heat pump system, be unfavorable for energy saving and heat pump system and safeguard.
And outdoor heat exchanger frosting initial stage only in inlet side frosting, only defrost repeatedly endless, frost layer gets deeper
When, it is possible in the frosting of heat exchanger air side, so the temperature of the non-frosting side of outdoor heat exchanger is higher than frosting when usually defrosting
Side, the air near non-frosting side rise and are not used for the defrosting of frosting side, waste of energy after being heated；When frost layer is thicker
When, once the frost for being attached to outdoor heat exchanger surface is melted, gap is formed between outdoor heat exchanger, outdoor heat exchanger just can not
It is conducted heat to frost layer by way of heat conduction, the hollowing frost shell for being difficult to remove may finally be formed.
