Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below with reference to drawings and Examples,
The present invention is described in further detail.
Fig. 1 is referred to, the figure show the flow chart of air-conditioner defrosting control method one embodiment of the present invention.
As schematically shown in Figure 1, the embodiment realizes that the method for air-conditioner defrosting control comprises the following steps the process for constituting：
Step 11：Determine that current outdoor coagulates dew-point temperature.
The solidifying dew-point temperature of current outdoor refers to outdoor air and is cooled down under the conditions of moisture content and air pressure are all immovable
To temperature during saturation, that is to say, that the temperature when the vapor in air is changed into dewdrop.As preferred embodiment,
At a temperature of identical outdoor environment, the corresponding outdoor solidifying dew-point temperature of different outdoor environment humidity values is different, thus, current outdoor
Solidifying dew-point temperature determines according to current outdoor environment temperature and current outdoor ambient humidity.Specifically, current outdoor is obtained
Environment temperature and current outdoor ambient humidity, for example, are obtained respectively by the temperature sensor and humidity sensor that are disposed in the outdoor
Proper preceding indoor environment temperature and current outdoor ambient humidity；Or, obtain current outdoor environment temperature by inquiring about current weather
Degree and current outdoor ambient humidity.Then, table search is compareed with solidifying dew-point temperature by known environment temperature, ambient humidity
Obtain the solidifying dew-point temperature corresponding with current environmental temperature and current environment humidity and coagulate dew-point temperature as current outdoor；Or
The solidifying dew-point temperature corresponding with current environmental temperature and current environment humidity is calculated by known formula it is used as and works as cup
Dew-point temperature is coagulated outward.
As a specific embodiment, when air-conditioning is started shooting and run, outdoor is constantly obtained according to design temperature sample frequency
Environment temperature, as current outdoor environment temperature, and temperature sampling frequency is 6-10 times/hour, can be by air conditioner external
The temperature sensor detection of setting is obtained.Current outdoor ambient humidity is detected by the humidity sensor being arranged on air-conditioning
, being obtained according to setting humidity sample frequency, humidity sample frequency is 6-10 times/hour.
Step 12：Current outdoor coil temperature is obtained, is made comparisons with the solidifying dew-point temperature of current outdoor, meeting defrosting condition
When, control air-conditioner defrosts into defrosting process.
Wherein, defrosting condition is：Current outdoor coil temperature coagulates dew-point temperature and current outdoor coil pipe less than current outdoor
Temperature reaches the current frosting according to determined by current outdoor ambient humidity less than the duration of the solidifying dew-point temperature of current outdoor
Time.
Specifically, because the solidifying dew-point temperature of current outdoor is critical-temperature when vapor is changed into dewdrop, if outdoor ring
Border temperature continuation reduces the dewdrop for then becoming and shows as frosting, therefore, it is by obtaining outdoor coil temperature and true with step 11
The solidifying dew-point temperature of fixed current outdoor is made comparisons.It is outdoor coil pipe used when outdoor coil temperature coagulates dew-point temperature less than current outdoor
On have dewdrop；If outdoor environment temperature continue reduce, it is outdoor coil pipe used on frost layer occurs.When outdoor coil temperature is just low
In in the solidifying dew-point temperature of the current outdoor shorter time period, air-conditioner heats situation and heat transfer effect or more satisfactory
, although very thin frost layer is tied on outdoor coil pipe used, but the defrosting of defrosting process can not have been immediately entered, can otherwise cause defrosting
Excessively frequently, especially the northern area in winter is very easy to reach outdoor coil temperature less than the solidifying dew-point temperature of current outdoor
Under state, frequently defrosting will influence indoor heating, energy consumption reduction.Therefore, it is also desirable to further according to current outdoor coil temperature
Judge whether control air-conditioner less than the duration of the solidifying dew-point temperature of current outdoor to be defrosted into defrosting process.Also, hold
The continuous time is not the changeless time, but determined by current outdoor ambient humidity, according to current outdoor ambient humidity
Difference and dynamic adjustable time for changing.Current coil temperature is being met less than the solidifying dew-point temperature of current outdoor and current
Outdoor coil temperature reaches current according to determined by current outdoor ambient humidity less than the duration of outdoor solidifying dew-point temperature
Heat pamp, control air-conditioner defrosts into defrosting process.Concrete methods of realizing into defrosting process defrosting can use existing
Technology is realized, is not herein specifically addressed.
As the presently preferred embodiments, current heat pamp is determined according to current outdoor ambient humidity, obtains current outdoor environment
Humidity, when the corresponding relation according to known humidity and heat pamp is obtained with frosting corresponding to current outdoor ambient humidity
Between, it is defined as current heat pamp.It is furthermore preferred that humidity is stored in a tabular form with the corresponding relation of heat pamp, according to
The humidity known and the corresponding relation of heat pamp, are obtained and the frosting corresponding to current outdoor ambient humidity by way of tabling look-up
Time.
In other embodiments, it is known that humidity and heat pamp corresponding relation for humidity range it is right with heat pamp
Should be related to, store in table form.For example, outdoor environment humidity（Relative humidity）During for 50%-60%, during corresponding frosting
Between be 75min；When outdoor environment humidity is 60%-70%, corresponding heat pamp is 60min；Outdoor environment humidity is 70%-
When 80%, corresponding heat pamp is 45min；When outdoor environment humidity is 80%-90%, corresponding heat pamp is
25min.The principle for determining the corresponding relation is, when outdoor environment temperature is identical, outdoor environment humidity is bigger, illustrates air
In water vapour content it is of a relatively high, if outdoor coil temperature be less than dew-point temperature, frosting velocity is faster, it is therefore desirable to shorter
Time judge whether control air-conditioner enter defrosting process defrosting, so outdoor environment relative humidity is higher, heat pamp is got over
It is short.
So, in the case where current outdoor ambient humidity is got, it is necessary first to determine current outdoor ambient humidity institute
The current humidity scope of category；Then, then by known humidity range and the corresponding relation of heat pamp, current humidity is determined
Heat pamp corresponding to scope.For example, the outdoor environment humidity for obtaining is 65%, belong to the humidity range of 60%-70%, by wet
Degree determines that current heat pamp is 60min with the corresponding relation of heat pamp.Namely：Under the outdoor environment humidity, work as acquisition
Current outdoor coil temperature when reaching 60min less than the duration of the solidifying dew-point temperature of current outdoor, control air-conditioner enters
Defrosting process defrosts.
Referring to Fig. 2, the figure show the stream of one embodiment of air-conditioner defrosting control method proposed by the invention
Cheng Tu.

When, control air-conditioner defrosts into defrosting process.
Step 21 and step 22 implement the description that may be referred to step 11 and step 12 in Fig. 1 embodiments.
Step 23：Current outdoor coil temperature is still constantly obtained during defrosting, when the condition for terminating defrosting is met,
Defrosting process is exited, stops defrosting.
The purpose that the step is performed is switched to heating mode and makes air-conditioner normal after the frost layer for ensureing on outdoor coil pipe used is melted
Operating, it is to avoid the phenomenon defrosted when occurring frostless occurs.
As the presently preferred embodiments, terminating defrosting condition includes meeting：
Outdoor coil temperature is less than the first temperature threshold and the duration reaches the condition of the first duration；Or
Outdoor coil temperature is more than or equal to the first temperature threshold but no more than second temperature threshold value and the duration reaches second and holds
The condition of continuous time；Or
Outdoor coil temperature is more than second temperature threshold value and the duration reaches the condition of the 3rd duration.
Wherein, the first duration be more than the second duration, the second duration be more than the 3rd duration.
Preferably, the first duration was 8-10min, and the second duration was 2-4min, and the 3rd duration is
0.5-1min.That is, outdoor coil temperature is higher, defrosting speed is faster, and the time for exiting defrosting is also shorter..
Influence angle of the various embodiments described above from ambient humidity to frosting velocity, humidity is bigger, then steam in air
Content is higher, and frosting velocity is faster, thus according to outdoor coil temperature with the relation of outdoor solidifying dew-point temperature and according to outdoor
Whether heat pamp determined by ambient humidity determines outdoor unit frosting situation and enters the decision condition of defrosting process defrosting, by
Determine whether to be defrosted into defrosting process in the frosting velocity speed that can be reflected according to humidity, can accurately determine the time of defrosting
