And the wireless communication device can be connected with the communication base station for data transmission.
The wireless communication device is a device for remote data transmission, and may be a GPRS module, or other communication modules, for example: the air conditioner integration WIFI module realizes data transmission by accessing a wireless network environment in a user home. Taking the GPRS module as an example, in order to achieve the acquisition of weather parameters, the GPRS module can perform data transmission with a remote server through a mobile network or a WIFI network, the remote server can send future weather parameters of a position where an air conditioner is located to the GPRS module, then the GPRS module sends data to a controller, and the controller serves as air conditioner operation control data.
It is understood that the GPRS module may also be replaced by a bluetooth module, and the bluetooth module may synchronize weather data with a mobile device (e.g., a mobile phone, a tablet computer, etc.) of a user after being paired by connecting with the mobile device. In addition, the humidity parameter of the weather acquired through the GPRS module or the WIFI module can also be realized in a mode of adding a humidity sensor through an air conditioner.
The weather parameters or weather data mentioned above refer to weather forecast parameters of the area or location where the air conditioner is located at the moment, including weather conditions at the moment, and weather conditions of 12 hours or 24 hours in the future, including temperature, humidity, sunny or rainy or thunderstorm, etc.
The compressor is provided with an electric heating device which is conventionally used for heating refrigeration oil or liquid refrigerant inside the compressor, and in the application, the electric heating device is used for heating the compressor which is stopped for a long time so as to improve the temperature inside the junction box. The electric heating device may be an electric heating belt, or may directly adopt a winding inside the compressor for heating, and specifically, a compressor having a winding heating function and a structure having an electric heating belt will be described.
The controller can acquire the ambient temperature detected by the air conditioner, and the real-time weather parameters and the future weather parameters acquired by the GPRS module or other ways; the controller can acquire the running state parameters of the unit, including the starting and stopping state of the compressor, the accumulated running time, the temperature of the top (and/or exhaust) of the compressor shell and the like; the controller may also control the switching of the compressor electrical heating strips.
The application provides an air conditioner is provided with the dampproofing mode of compressor, and under this dampproofing mode, the unit improves the operating frequency of compressor according to the instruction of controller, perhaps, the electric heating area or the winding heating of control compressor are opened or are closed. When the frequency of the compressor is increased, the heat productivity of the motor is increased, the temperature of a cylinder body of the compressor is increased, and the temperature of the junction box is increased through heat transfer; when the electric heating belt of the compressor is opened, heat of the heated shell of the compressor can be transferred to the interior of the junction box of the compressor, so that air in the junction box is heated and is higher than the temperature of the air outside.
Fig. 6 is a schematic diagram illustrating the moisture-proof control of the air conditioner, and the parameters are simplified for understanding. After detecting the corresponding parameters, the controller judges:
the first condition is as follows: whether the compressor is in a running state;
and a second condition: whether the temperature of the top of the compressor shell (and/or the exhaust gas) in the continuous time T1 is less than or equal to T1;
and (3) carrying out a third condition: whether the environmental humidity is equal to or greater than RH1 or whether the weather conditions at the moment and at the future time t2 are overcast and rainy, thunderstorm, rain and snow and the like;
if the conditions I, II and III are simultaneously met, the air conditioner enters a damp-proof mode of the compressor.
The control mode in the moisture-proof mode of the compressor is as follows:
if the current ambient humidity or the average humidity at the future time t2 is [ RH1, RH2 ], turning on the electric heating belt of the compressor;
if the current ambient humidity or the average humidity at the future time t2 is [ RH2, RH3 ], increasing the operating frequency of the compressor by a Hz every t3 time, and increasing m Hz at most in an accumulated manner;
if the current ambient humidity or the average humidity at the future time t2 is between [ RH3 and RH4], the operation frequency of the compressor is increased by b Hz every t3 time, at most, n Hz is increased cumulatively, and meanwhile, the electric heating belt of the compressor is started.
Conditions for exiting the moisture-proof mode:
the first condition is as follows: compressor shell top (and/or discharge) temperature > T2;
and a second condition: the current ambient humidity or the average humidity at the future time t2 is less than or equal to RH 5;
and if the controller detects that the above arbitrary conditions are met, the controller exits the moisture-proof mode.
The time T1, T2, T3, the humidity RH1, RH2, RH3, RH4, RH5, the frequency a, b, m, n, the temperature T1, T2 are preset values. Specifically, T1 is more than 0 and more than T3 and more than T2 and less than 10 hours, RH5 is more than 30 percent and more than RH1 and more than RH2 and more than RH3 and more than RH4 and less than 100 percent, m is more than 0 and more than b and more than n and less than 20Hz, and T1 is more than 20 ℃ and more than T2 and less than 100 ℃. Specifically, T1, T2 and T3 are 20min, 3 hours and 2min respectively, RH1, RH2, RH3, RH4 and RH5 are 65%, 75%, 85%, 100% and 60% respectively, a, b, m and n are 3Hz, 4Hz, 10Hz and 15Hz respectively, and T1 and T2 are 23 ℃ and 50 ℃ respectively.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
