AI Technical Summary
The temperature control methods of existing home appliances result in significant temperature fluctuations, affecting the user experience. In particular, when the compressor is running at its lowest frequency, the cooling/heating capacity cannot be further reduced, leading to repeated temperature fluctuations.
By adjusting the first expansion valve in the heat pump system, the refrigerant flow rate into the third heat exchanger is controlled, thereby adjusting the cooling or heating capacity of the first heat exchanger to ensure that the actual saturation temperature is within the target range. Combined with fan speed adjustment, precise control of indoor temperature is achieved.
It reduces indoor temperature fluctuations, improves user experience, and stores excess cold or heat through a third heat exchanger, reducing energy waste.
