Title:
CONTROL METHOD AND SYSTEM FOR WATER HEATER UNIT, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/066353
Kind Code:
A1
Abstract:
The present disclosure relates to a control method and system for a water heater unit, and a computer-readable storage medium. The water heater unit comprises a compressor, a water-side heat exchanger, an evaporative heat exchanger and an expansion valve, wherein the expansion valve is located between the water-side heat exchanger and the evaporative heat exchanger. The control method for a water heater unit comprises: acquiring a refrigerant saturation temperature corresponding to the pressure at a refrigerant discharge pipe of a water-side heat exchanger, recording the refrigerant saturation temperature as a first temperature, acquiring a discharge-water temperature of the water-side heat exchanger, and comparing the first temperature with the discharge-water temperature, so as to obtain a first comparison result; acquiring the temperature at the refrigerant discharge pipe of the water-side heat exchanger, recording the temperature as a second temperature, acquiring an input-water temperature of the water-side heat exchanger, and comparing the second temperature with the input-water temperature, so as to obtain a second comparison result; and adjusting the opening degree of an expansion valve according to the first comparison result and the second comparison result. The opening degree of an expansion valve is adjusted by means of determining a heat exchange state of a water-side heat exchanger, such that sufficient condensation of the water-side heat exchanger can be facilitated and high adjustment accuracy is achieved.
