Abstract

The invention provides a frequency and flow changing heat pump water heater, relates to a liquid heater with a heat generation device by using a heat pump. The frequency and flow changing heat pump water heater comprises a unit part, a water circulating part, water tubes and communication lines connected inside the water circulating part. The unit part comprises a frequency-changing compressor, a cross tee change valve, a double pipe condenser, an unloading valve, an electronic expansion valve, an evaporator, a fan, a controller, various temperature sensors and pressure sensors. The water circulating part comprises a pump, an outlet valve, a ball valve, a water tank, a water temperature sensor and a filter. The frequency and flow changing heat pump water heater takes the frequency-changing compressor as the power source of the system, takes the electronic expansion valve as a throttling device and uses the water temperature sensor to prevent freezing. Compared with combustion gas, fuel oil, coal or electronic water heater, the frequency and flow changing heat pump water heater has safety, environmental protection and energy saving properties. Compared with the heat pump hot water units, the throttling of which uses rated frequency compressor and thermostatic expansion valve or capillary tubes, the frequency and flow changing heat pump water heater has high heating output power, good heating effect and good environmental adaptability.

Description

technical field [0001] The invention relates to a liquid heater using a heat pump with a heat generating device, in particular to a heat pump water heater with variable frequency and variable flow. Background technique [0002] Traditional water heaters usually use gas, oil, coal or electricity as heating energy, and the newer ones use solar energy. Gas, oil, and coal-fired water heaters use the heat generated by the combustion of combustible substances to heat water. When burning, it is easy to cause insufficient combustion due to insufficient oxygen supply, and it is also easy to cause fluctuations in hot water temperature due to unstable water pressure. Exhaust gas poisoning and The danger of scalding, so the safety and usability are poor, and because a large amount of non-renewable energy must be consumed, the use cost is high, and the pressure on the environment is great. Electric water heaters have low utilization efficiency of electric energy, consume a large amount ...
