Valve 14 is out of service, runs under long-time low-temperature condition to avoid air-conditioning and damages to components such as indoor unit coil pipes 23.
In process of refrigerastion, the temperature that indoor unit coil temperature sensor 22 measures is likely lower than anti-freeze protection temperature.
In order to avoid frosting effect of the anti-freeze defencive function to indoor unit coil pipe 23 impacts, indoor machine controller 21 can pass through
The temperature that the indoor unit coil temperature sensor 22 of simulation is sent to outdoor controller 11, makes the antifreeze of outdoor controller 11
It is invalid to tie defencive function, triggering anti-freeze protection bring is avoided to influence.
For example, anti-freeze protection temperature can be 5 degrees Celsius.Refrigerating state is in compressor 13 and electric expansion valve 14
When, 10 degrees Celsius of temperature of the indoor unit coil temperature sensor 22 that indoor machine controller 21 can be simulated by lasting transmission,
Keep the anti-freeze defencive function of outdoor controller 11 invalid.
In certain embodiments, as shown in figure 3, on the basis of method shown in Fig. 2, this method can also include step
S210:
S210, before air-conditioning enters the heating operations of clean conditions, control air-conditioning enter protection process.
Before air-conditioning enters the heating operations of clean conditions, control air-conditioning enters protection process, avoids quickly cutting for state
It changes, damages compressor.
In certain embodiments, as shown in figure 4, after air-conditioning enters protection process, indoor machine fan 24 is controlled with default
Revolving speed operation.
In certain embodiments, as shown in figure 5, after air-conditioning enters protection process, control indoor machine fan 24 stops fortune
Row.
In certain embodiments, after air-conditioning enters the 5th time of protection process, control air-conditioning enters the system of clean conditions
Thermal process.
