Fig. 5 is an air-conditioner refrigeration running method programme diagram of the present invention.
As shown in Figure 5, in the above-mentioned air-conditioner refrigeration running method, if not cooling operation, the indoor fan 3 that shuts down, outdoor fan 5 and compressor 6.(S51，S52)
On the contrary, in the above-mentioned air-conditioner refrigeration running method, if cooling operation, the relatively desired temperature of the indoor temperature of indoor temperature transmitter 22 perception and user input.(S53)
Through above-mentioned comparison, if indoor temperature is not higher than desired temperature, weak wind pattern rotating room internal fan 3, outdoor fan 5 and compressor 6 shut down.(S54)
That is, in the stage, corresponding with the indoor load situation at said procedure in order to reduce the electric power that need consume when compressor 6 drives, stop compressor 6, weak wind pattern rotating room internal fan 3, room air is cooled off by indoor heat converter 2.
On the contrary, through above-mentioned comparison, if indoor temperature, confirms that compressor 6 is at present whether in running than the desired temperature height.(S55)
If compressor 6 is not in operation process, confirming that compressor 6 is whether in 3 minutes deferring procedures.(S56)
If be confirmed to be compressor 6 in 3 minutes deferring procedures, with weak wind pattern rotating room internal fan 3, keep the halted state of compressor 6, outdoor fan 5 shuts down.(S57)
That is, in the stage, in 3 minutes deferring procedures of compressor 6, weak wind pattern rotating room internal fan 3 makes room air be cooled off by indoor heat converter 2 at said procedure.
On the contrary, if but recognize compressor 6 not in 3 minutes deferring procedures, with rated frequency (for example, 60hz) running compressor, rotating room's external fan 5 is with the setting air quantity rotating room internal fan 3 of user's input.(S58)
In addition, when judging that (S55) compressor 6 is just in operation process, the indoor temperature Ti of indoor temperature transmitter 22 perception at setting-up time (for example, 1 minute) during maintain and set between the indoor temperature scope (promptly, T2＜Ti＜T1), the outdoor temperature To of outdoor temperature sensor 33 perception at above-mentioned setting-up time (for example, 1 minute) during maintain and set between the outdoor temperature scope (promptly, T3＜To＜T4) uses then that (for example, 60hz) frequency in a low stage is (for example than rated frequency, 55hz) running compressor 6, meanwhile, superpower wind pattern rotating room internal fan 3, rotating room's external fan 5.(S59，S60，S61，S62，S63，S64)
On the contrary, when judging that (S55) compressor 6 is at present just in operation process, the indoor temperature Ti of indoor temperature transmitter 22 perception is beyond setting indoor temperature scope, perhaps the outdoor temperature To of outdoor temperature sensor 33 perception is beyond setting outdoor temperature scope, perhaps (for example at setting-up time, 1 minute) during the setting outdoor temperature scope that can not continue to keep the setting indoor temperature scope of indoor temperature Ti and can not continue to keep outdoor temperature To, with rated frequency (for example, 60hz) make compressor 6 runnings, with the setting air quantity rotating room internal fan 3 of user's input, rotating room's external fan 5.(S59，S60，S61，S62，S65，S66)
Set indoor temperature scope (that is T2＜Ti＜T1) and set the outdoor temperature scope (that is, T3＜To＜T4) is the temperature range that generates the high temperature humid climate of the above condensed water of designated value on the surface of indoor heat converter 2, by the test decision, here.
Below, the minimum of a value of setting the indoor temperature scope is 28 ℃, and the maximum of setting the indoor temperature scope is 30 ℃, and the minimum of a value of setting the outdoor temperature scope in addition is 24 ℃, and the maximum of setting the outdoor temperature scope is 26 ℃, describes thus.
That is, for the refrigeration running method of above-mentioned air-conditioner, be 29 ℃ at indoor temperature Ti, outdoor temperature is 25 ℃, computing time.(S59，S60，S61)
Afterwards, maintain between 28 ℃ to 30 ℃ during the indoor temperature Ti setting-up time (for example, 1 minute), outdoor temperature To maintains between 24 ℃ to 26 ℃ during setting-up time (for example, 1 minute), then reverts to 0 computing time.(S62，S63)
Then, use than rated frequency (for example, 60hz) frequency of low one-level (for example, 55hz) running compressor 6 is meanwhile with superpower wind pattern rotating room internal fan 3, rotating room's external fan 5.(S64)
That is, air-conditioner is with few relatively power consumption drive compression machine 6 time, and the condensation water quantities that generate on indoor heat converter 2 surfaces minimize, at this moment because indoor fan 3 rotates with superpower wind pattern, thus cold air be discharged to rapidly indoor in.
On the contrary, if indoor temperature Ti is 31 ℃ or 27 ℃, (for example, 60hz) running compressor 6 is with the setting air quantity rotating room internal fan 3 of user's input, rotating room's external fan 5 with rated frequency.(S59，S65)
In addition, for the refrigeration running method of above-mentioned air-conditioner, indoor temperature Ti is 29 ℃, but outdoor temperature (To) is 23 ℃ or 27 ℃, then use rated frequency (for example, 60hz) running compressor 6, with the setting air quantity rotating room internal fan 3 of user's input, rotating room's external fan 5.(S59，S60，65)
In addition, in indoor temperature (Ti) is that 29 ℃ and outdoor temperature (To) are under 25 ℃ the situation, indoor temperature (Ti) changes 27 ℃ or 30 ℃ in the computing time process, perhaps outdoor temperature (To) changes 23 ℃ or 27 ℃ into, then the time of calculating is reverted to 0, use rated frequency (for example, 60hz) running compressor 6 then, with the setting air quantity rotating room internal fan 3 of user's input, rotating room's external fan 5.(S59，S60，S61，S62，S63′，S65)
