Description
Technical field
The present invention relates to Defrost technology field, in particular to a kind of defrosting control method, a kind of defrosting control device
With a kind of air conditioner.
Background technology
In the case that outdoor environment is relatively low in winter, when heat pump type air conditioner runs on heating mode, outdoor unit condensation
Device can gradually frosting, and frost layer can be increasingly thicker, and then influences the heat exchange of condenser.Thickening with frost layer, condenser changes
Thermal energy power gradually can lose the ability that heat is absorbed from outdoor environment, so as to cause the heating effect of complete machine more next worse and worse
It is poorer.When frost layer thickeies to a certain extent, need to carry out defrost processing, frost layer is melted and then reentered heating shape
State.
During the defrosting control of the relevant technologies, typically declined by judging evaporator tube temperature or condenser tube temperature
Whether amplitude is more than certain threshold value, and to determine the need for defrosting, and evaporator tube temperature or condenser tube temperature can be by outdoors
The influence of temperature change, for example, when outdoor temperature continuously decreases, evaporator tube temperature or condenser tube temperature also can be with outdoor temps
The reduction of degree and reduce.When the preset temperature condition that the amplitude satisfaction for reducing temperature defrosts, heat pump type air conditioner can be certainly
Dynamic to enter defrosting mode, but in the case where outdoor air is relatively dry, outdoor condenser frosting or is not only tied
A small amount of frost will enter " frostless defrost " pattern at this time, since defrosting mode needs the heating process of stopping indoor unit, because
This, not only affects the usage experience of user, but also also results in waste of energy.
Invention content
The present invention is directed at least solve one of technical problem present in the prior art or the relevant technologies.
