Description
Technical field
The method of air-conditioning defrost is controlled the present invention relates to air-conditioning technical field more particularly to a kind of subregion and uses the party
The air-conditioner set of method.
Background technique
China is vast in territory, and the weather conditions of different geographical are rather different, especially winter, due to cold wave activity, north and south
Meteorological condition difference is very big, and air conditioner heat pump system also differs greatly in different regions practical operation situation, for example, in environment temperature
The long-term South China for being higher than 7 DEG C or more, the heat supply in winter phase is short, and calorific requirement is small, unit general frost-free, heating performance when running
Coefficient is high；And Central China and inclined northern territory, winter temperature are lower, air humidity is larger, air-conditioning heat pump easy frosting when running, but frost
Layer is relatively thin；North of North China and the Northeast's temperature are extremely low, but air humidity is lower, and heat pump unit is not easy frosting, but frosting
When easily form thicker frost layer.And it is current, the air conditioner and heat pump unit defrosting control system and defrosting time of most of producers are unified solid
It is fixed constant, the problems such as thus unit can have frostless defrost, and defrost is not clean, it cannot achieve the optimum control of defrost.
For different zones, Different climate feature and meteorological condition, air conditioner and heat pump unit is transported according to different defrosting modes
Row is more advantageous to the effect and effect property of unit defrost.For example, for the region for being easier to frosting, the time interval and defrosting of defrosting
Time can be shorter；For being not easy the region of frosting, defrosting time interval can be relatively longer.Authorization Notice No. is
CN1737444A, the Chinese patent of entitled " air conditioner divisional defrosting control method " disclose one kind and " pass through measuring chamber
It external heat exchanger coil temperature, environment temperature and determines the need for carrying out defrosting behaviour according to the coefficient of zone locations setting
Unit may be implemented according to regional climatic characteristic in the control method of work ", passes through for different zones and manually sets corresponding dial-up,
And then realize that unit operation more optimizes reasonable defrosting control logic, avoid unit from running unreasonable defrost program.However,
This method has certain problems the accurate setting of dial-up.If for presetting a certain spy when heat pump unit development and production
Determine dial-up parameter, then the territory of use of these units is restricted, i.e., the unit of a certain specific dial-up is only applicable in corresponding area；
If the dial-up parameter needs in units' installation debugging process, it is manually set, then there is the inconvenience of operation, and may deposits
In the risk of setting mistake.
Application publication number is CN106766019A, entitled " air-conditioning defrosting control system and air-conditioning defrosting control side
The Chinese patent and application publication number of method " are CN107339772A, entitled " air-conditioning defrosting control method and device "
Chinese patent disclose realize heat pump air conditioner intelligent defrosting method, both methods be required to unit run when, benefit
Real-time environmental parameter is obtained with wireless communication apparatus, and then is run using the defrost that the parameter obtained participates in unit, to mention
Rise the accuracy and high efficiency of unit defrost.But above-mentioned two patent the method has a problem that, that is, if unit
In operational process, because when network signal is unstable or no signal, wireless communication apparatus will be unable to accurately obtain environmental parameter, that
Adversely effected possibly even break down is shut down in unit defrost operation, operates normally to unit and user uses and generates very
It is big to influence.

History climate parameter；The climate parameter stored in the historical climate parameter and mainboard that will acquire is compared and selects mutually suitable with area
The defrost pattern answered.
The climate parameter includes：Environment temperature, relative humidity, time, air humidity content, dew-point temperature and/or day
Vaporous condition.
In one embodiment, the method including subregion control air-conditioning defrost includes：
When air-conditioner set booting heating operation, passes through wireless communication module and obtain geographical regional historical environment temperature where air-conditioner set
Spend TaWith history relative humidity RHa, and following judgement is done：
As history environment temperature TaMeet T1< Ta< T2, and history relative humidity RHa meets RH1< RHa < RH2When, air conditioner
Group selection defrost pattern I carries out defrosting operation；
As history environment temperature TaMeet T3< Ta< T4, and history relative humidity RHa meets RH3< RHa < RH4When, air conditioner
Group selection defrost pattern II carries out defrosting operation；
As history environment temperature TaMeet Tn-1< Ta< Tn, and relative humidity RHa meets RHn-1< RHa < RHnWhen, unit will select
It selects matching defrosting mode N and carries out defrosting operation.
The present invention also proposes a kind of air-conditioner set, which uses above-mentioned subregion air-conditioning defrosting control method, packet
It includes：Memory module, for storing the defrost pattern adaptable with area；Communication module, for obtaining air-conditioner set installation region
Historical climate parameter；And matching module, the climate parameter stored in historical climate parameter for will acquire and memory module
It is compared and selects the defrost pattern adaptable with area.
The historical climate parameter characteristic in the specific area that the present invention can be installed according to air-conditioner set, selection are adapted to this
The optimal defrost operational mode of local climate feature, combines unit actual motion with this area's meteorological condition, promotes heat pump
The accuracy of unit defrost operation, and then ensure the high efficiency of unit heating operation.
