Abstract

The invention provides a high-temperature heat pump water heater, comprising a compressor, a four-way reversing valve, a water tank, a condenser arranged in the water tank, a throttling device and an evaporator, wherein the compressor, the condenser, the throttling device and the evaporator The throttling device includes an electronic expansion valve and a capillary arranged in parallel, and a real-time flow control device is provided at the liquid inlet end of the capillary. The real-time flow control device includes a solenoid valve and a controller, and the controller controls the solenoid valve. The opening frequency of the solenoid valve is used to adjust the refrigerant flow through the solenoid valve. Furthermore, the high-temperature heat pump water heater can adjust the refrigerant flow through the throttling device in real time by controlling the opening and closing of the electronic expansion valve and the solenoid valve. The control accuracy of the circulation flow and the operating efficiency of the compressor.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a high-temperature heat pump water heater. Background technique [0002] Air energy water heater, also known as air source heat pump water heater, its working principle is to absorb the low-temperature heat in the air, vaporize the refrigerant through the evaporator, and then pressurize and heat up after being compressed by the compressor. This is used to heat the water temperature. With the development of society, people's requirements for domestic water are getting higher and higher. Heat pump water heaters are required to produce domestic water as high as 80 °C under the condition of external ambient temperature of -7 °C to 43 °C. To meet the needs of the operating range, high-temperature heat pump water heaters came into being. The throttling device in the existing high-temperature heat pump water heater generally adopts a single thermal expansion valve or electronic expansion ...
