Abstract
The invention provides an anti-cold-air control method and device for air conditioner heating startup. The anti-cold-air control method for air conditioner heating startup includes the steps that indoor environment temperature T1 and outdoor environment temperature T2 are obtained; the indoor environment temperature T1 is compared with a first preset value Ta, when T1is 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, an internal fan is started when an air conditioner is started. According to the anti-cold-air control method for air conditioner heating startup, as the indoor environment temperature T1 and outdoor environment temperature T2 are judged, and the internal fan is started under the condition that the indoor environment temperature T1 and the outdoor environment temperature T2 are too high, it is prevented that as a great deal of heat cannot be discharged into the indoor environment in time, exhaust pressure rises sharply to cause a pipeline to break.
Description
Technical field

Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is that air-conditioning heating according to the present invention is started shooting the principle schematic of anti-cold wind control method;
Detailed description of the invention
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, air-conditioning heating according to the present invention is started shooting anti-cold wind control method, comprising: 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, outdoor environment temperature T2 and the second preset value Tb is contrasted, as T2 >=Tb, during starting of air conditioner, open inner blower.The present invention is by judging indoor environment temperature T1 and outdoor environment temperature T2, when indoor environment temperature T1 and outdoor environment temperature T2 is too high, start inner blower, thus prevent a large amount of heat to be discharged in indoor environment in time, cause pressure at expulsion sharply rise and cause pipe breakage.Namely compared to existing technology in anti-cold wind stage inner blower do not start all the time, the present invention, when indoor and outdoors temperature is too high, optionally starts, thus prevents pressure at expulsion from sharply rising.
Usually, Ta≤30 DEG C.Even if meet the requirement that there will not be system high pressure overshoot phenomenon when environment temperature is higher outside.Preferably, as T2 >=Tb, further outdoor environment temperature T2 and the 3rd preset value Tc is contrasted, namely outdoor environment temperature T2 is distinguished further, also namely carry out further micro-stepping control according to different heat absorption rates.Particularly, as Tc >=T2 >=Tb, inner blower runs with the first wind shelves; As T2 > Tc, inner blower runs with the second wind shelves, and wherein, the air quantity of the second wind shelves is greater than the air quantity of the first wind shelves.Namely as Tc >=T2 >=Tb, outdoor environment temperature T2 is relatively low, and heat absorption rate is also relatively low, and inner blower runs with the first wind shelves (low wind shelves) and can prevent pressure at expulsion from sharply rising; As T2 > Tc, outdoor temperature is too high, and heat absorption rate is also relatively very fast, and in order to prevent pressure at expulsion from sharply rising, inner blower ran, to improve rate of heat dispation with the second wind shelves (apoplexy shelves) in the anti-cold wind stage.Preferably, 30 DEG C≤Tb≤50 DEG C, 30 DEG C≤Tc≤50 DEG C, and Tb < Tc, thus prevent pressure excessive.
Usually, as T1 < Ta, when namely indoor environment temperature T1 is lower, rate of heat dispation is very fast, and in the anti-cold wind stage, inner blower adopts existing control.Namely after starting of air conditioner, detect the refrigerant pipeline temperature T3 of indoor set in real time, and refrigerant pipeline temperature T3 and the 4th preset value Td is contrasted, as T3 >=Td, open inner blower.
Similarly, as T1 >=Ta, and during T2 < Tb, although namely indoor environment temperature T1 is higher, be unfavorable for heat radiation, outdoor environment temperature T2 is lower, heat absorption rate is also slower, there is not the risk that pressure at expulsion sharply rises, in the anti-cold wind stage, inner blower adopts existing control.Namely after starting of air conditioner, detect the refrigerant pipeline temperature T3 of indoor set in real time, and refrigerant pipeline temperature T3 and the 4th preset value Td is contrasted, as T3 >=Td, open inner blower.
Present invention also offers a kind of and aforementioned air-conditioning heating air-conditioning heating corresponding to anti-cold wind control method of starting shooting to start shooting anti-cold wind control device, its control principle and air-conditioning heating anti-cold wind control method of starting shooting is similar, repeats no more.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
Air-conditioning heating according to the present invention is started shooting anti-cold wind control method, by judging indoor environment temperature T1 and outdoor environment temperature T2, when indoor environment temperature T1 and outdoor environment temperature T2 is too high, start inner blower, thus prevent a large amount of heat to be discharged in indoor environment in time, cause pressure at expulsion sharply rise and cause pipe breakage.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
