Intelligent thermostatic control method and device for an air conditioner blowing cold and hot air

An intelligent thermostatic control device for an air conditioner blowing cold and hot air and having a compressor, a condenser, an expansion valve and an evaporator sequentially connected in series, the intelligent thermostatic control device comprising:

• a thermostatic controller having:
• a thermal load estimation module receiving external signals to calculate an estimated thermal load and an estimated cooling/heating capacity corresponding to the estimated thermal load;
• a computation module receiving external signals to calculate an actual cooling/heating capacity;
• and
• a control module receiving the estimated cooling/heating capacity from the thermal load estimation module, calculating a difference value between the actual cooling/heating capacity and the estimated cooling/heating capacity, and outputting a control signal to the air conditioner according to the difference value;
• a sensor group electrically connected to the thermostatic controller, having a sunlight intensity sensor, multiple temperature sensors and multiple pressure sensors for respectively detecting a sunlight intensity, temperature and pressure of the air conditioner, and providing signals to the thermal load estimation module and the computation module;
• and
• a configuration unit electrically connected to the thermostatic controller to configure a temperature and transmit a configured temperature signal to the thermostatic controller.
