Method for automatically controlling partial functions of air conditioner and heat pump water heater based on weather forecast data

Abstract

The present invention provides a method for automatically controlling partial functions of an air conditioner and a heat pump water heater based on weather forecast data. According to the method, mainly the control on an air conditioner and the big data of weather forecast are combined, such that the air conditioner can predict and automatically control the opening and the closing of the electricheating tape of a compressor during the standby of the air conditioner according to the temperature change in weather forecast, the amount of new air introduced by an indoor unit can be automaticallycontrolled according to outdoor air quality report data while whether an indoor heat exchanger is clogged by dirt can be judged by combining historical air quality data and the gas discharging temperature or the pressure data of the compressor, the dehumidification period or logic can be automatically established according to local seasonal climate, or the evaporation pressure during cooling can be adjusted sp as to make the air conditioner dehumidify according to the concrete humidity condition, the temperature change at the current day can be predicted, the water boiling temperature can be adjusted, the running period achieving the highest energy efficiency can be determined, and the time for boiling water can be calculated and is transmitted to a client terminal.

Description

technical field

[0001] The invention belongs to the technical field of control, and in particular relates to a method for realizing automatic control of some functions of an air conditioner and a heat pump water heater based on weather forecast data. Background technique

[0002] At present, the control of air conditioners or heat pump water heaters is mostly based on the remote control or wire controller to control the fresh air function, dehumidification function of the internal unit, and the heating time of the heat pump water heater. This control method mainly has the following shortcomings:

[0003] 1. The indoor unit of the air conditioner cannot control the fresh air volume according to the quality of the outdoor air environment, and it is easy to introduce low-quality outdoor air into the room.

[0004] 2. When the outdoor air quality is poor, such as in a dusty environment, the outdoor heat exchanger is more likely to be dirty and blocked. Under refrigeration condit...

Embodiment 1

[0038] Example 1, such as figure 2 image 3 As shown, since the current air-conditioning indoor units or fresh air fans cannot control the fresh air volume according to the quality of the outdoor air environment, it is easy to introduce low-quality outdoor air into the room. Control, so that it can obtain the air quality data in the weather forecast, and carry out specific logic control on the amount of fresh air introduced according to these data.

[0039] Its control method is as figure 2As shown, after the unit is running, the communication module set on the unit will send the fresh air demand information and air conditioner location information set by the user to the Internet server, and the Internet server will send back the air quality data information of the area in the weather forecast, The air quality data sent back is mainly air quality grade information; meanwhile, the indoor air quality detection system will periodically detect the indoor air quality, and calcu...

Embodiment 2

[0057] Example 2, such as Figure 4 As shown, when the outdoor air quality is poor, such as in a dusty environment, the outdoor heat exchanger is more likely to be dirty and blocked. In this case, after the heat exchanger of the outdoor unit is dirty and blocked, the exhaust temperature and pressure of the compressor will decrease, but the existing air conditioner cannot prompt the user with the information of the air conditioner dirty and blocked according to these information, which will eventually lead to the shutdown protection of the unit. Therefore, this embodiment mainly The control design is carried out for the dirty and clogged outside of the air conditioner; it can obtain the historical air quality data in the weather forecast, and use these data combined with the current changes in the discharge temperature or pressure of the compressor to comprehensively judge whether the outdoor heat exchanger is If there is a dirty blockage, if it is judged that there is dirty bl...

Embodiment 3

[0076] Example 3, such as Figure 5 As shown, due to the different seasonal climates in various regions, the unit cannot perform specific control according to the special seasonal climate. For example, South China has a typical oceanic subtropical monsoon climate. The air flow meets the cold air coming down from the north of China and forms a quasi-stationary front in the south of the Lingnan area. This makes the weather in South China very cloudy and very humid. There will be light rain or heavy fog during the period. After entering the warm and humid air, it is easy to condense on its surface and form water droplets, which also causes the weather phenomenon of "returning to the south". However, our existing air conditioners do not have the function of automatically adjusting the indoor humidity for these special climates, or according to the humidity. Information automatically controls the function of evaporation temperature; therefore, this embodiment is mainly designed to ...
