Abstract
The invention provides a control method and a control device for heating and starting of an air conditioner. The air conditioner heating starting control method comprises the following steps: obtaining an indoor environment temperature T1 and an outdoor environment temperature T2; comparing the indoor ambient temperature T1 with a first preset value Ta; when T1 is less than Ta, the external fan is started when the compressor is started; when T1 is larger than or equal to Ta, the outdoor environment temperature T2 is compared with a second preset value Tb, and when T2 is larger than or equal to Tb, the compressor is started, the first preset time T is delayed, and then the outer fan is started. According to the invention, by judging the indoor environment temperature T1 and the outdoor environment temperature T2, the external fan is turned on in a delayed manner under the condition that the indoor environment temperature T1 and the outdoor environment temperature T2 are too high, so that the heat absorption capacity is reduced, and the phenomenon that a pipeline is broken due to the fact that the exhaust pressure is increased sharply because a large amount of heat cannot be discharged into the indoor environment in time is prevented.

According to the air-conditioning heating start-up control method and control device of the present invention, by judging indoor environment temperature T1 and room
External environment temperature T2, in the case that environment temperature T1 and outdoor environment temperature T2 are too high indoors, by outer blower fan delayed start-up, from
And caloric receptivity is reduced, prevent substantial amounts of heat not to be discharged in time in indoor environment, cause pressure at expulsion to steeply rise and cause pipe
Road ruptures.
Brief description of the drawings
The accompanying drawing for forming the part of the application is used for providing a further understanding of the present invention, schematic reality of the invention
Apply example and its illustrate to be used to explain the present invention, do not form inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is the principle schematic according to the air-conditioning heating start-up control method of the present invention；
Embodiment
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, according to the air-conditioning heating start-up control method of the present invention, including：Obtain indoor environment temperature T1 and
Outdoor environment temperature T2；Indoor environment temperature T1 and the first preset value Ta is contrasted；As T1 ＜ Ta, opened when starting compressor
Outer blower fan；As T1 >=Ta, outdoor environment temperature T2 and the second preset value Tb is contrasted, as T2 >=Tb, after starting compressor
First preset time t that is delayed is then turned on outer blower fan.The present invention by judging indoor environment temperature T1 and outdoor environment temperature T2,
In the case that indoor environment temperature T1 and outdoor environment temperature T2 are too high, outer blower fan delayed start-up so as to reduce caloric receptivity, is prevented
Only substantial amounts of heat can not be discharged in indoor environment in time, caused pressure at expulsion to steeply rise and caused pipe breakage.I.e. compared to existing
There is in technology starting of air conditioner be switched on outer blower fan, the present invention indoors with outdoor temperature it is too high in the case of, exogenous wind machine can be made
Delay start, so as to reduce heat heat absorption, so as to prevent pressure at expulsion from steeply rising.
Preferably, the first preset time t is less than or equal to 10 minutes, when compressor start is more than the first preset time t
Afterwards, start outer blower fan, start so that control is normal, meet stable operation requirement.
Usually, as T1 ＜ Ta, i.e., when indoor environment temperature T1 is relatively low, rate of heat dispation is very fast, in the anti-cold wind stage, outside
Blower fan uses existing control.After i.e. air-conditioning opens compressor start, that is, open outer blower fan heat exchange.Similarly, as T1 >=Ta,
And during T2 ＜ Tb, although i.e. indoor environment temperature T1 is higher, be unfavorable for radiating, outdoor environment temperature T2 is relatively low, heat absorption speed
Rate is also relatively slow, and the risk steeply risen in the absence of pressure at expulsion, in the anti-cold wind stage, outer blower fan uses existing control.
In the present invention, inner blower uses and existing similar control, i.e., after air-conditioning opens compressor start, monitoring in real time
Refrigerant pipeline temperature T3, and refrigerant pipeline temperature T3 and the 3rd preset value Tc is contrasted, as T3 >=Tc, inner blower is opened, from
And indoor set is set to blow out warm wind, the operation of air-conditioning normal table.Preferably, 0 DEG C≤Ta≤30 DEG C, 30 DEG C≤Tb≤50 DEG C, so as to
Prevent that pressure is excessive.
Present invention also offers a kind of air-conditioning heating start control dress corresponding with foregoing air-conditioning heating start-up control method
Put, its control principle is similar with air-conditioning heating start-up control method, repeats no more.
