Abstract

The invention relates to a domestic normal pressure heat pump water heater and a control method thereof. The domestic normal pressure heat pump water heater comprises a heat preservation water tank, a heat exchanger, a heat pump system, an electric three-way adjusting valve, a water pump, a flow sensor and a water level sensor; the electric three-way adjusting valve is provided with an a end opening, a b end opening and a c end opening; the a end opening is communicated with a water outlet hole of the heat preservation water tank; the b end opening is communicated with a water flow channel through a water pump; the c end opening is communicated with a water inlet pipe; the flow sensor is arranged at the b end opening; the water level sensor is arranged inside the heat preservation water tank; a pressure switch, a water flow switch and a hot water outlet pipe are arranged between a water outlet hole of the heat preservation water tank and the a end opening. The domestic normal pressure heat pump water heater can control a water pump and achieve circulating heating operation in combination with the water level, the water pressure and the water flows and also can control the water flowing speed through the electric three-way adjusting valve to directly heat water entering the heat exchanger to be in the set temperature and store the water to the heat preservation water tank to enable the water outlet temperature and the water pressure to be constant.

Description

technical field [0001] The invention relates to the technical field of heat pump water heaters, in particular to a household normal-pressure heat pump water heater and a control method thereof. Background technique [0002] Chinese Patent No. CN201020209345.5 disclosed a heat pump water heater on January 26, 2011, including a main unit, a heating water tank, and a water storage tank. The main unit and the heating water tank are connected to each other with a water outlet pipe and a water inlet pipe, wherein the water outlet pipe is connected to a Circulating water pump, the water inlet pipe is connected with a three-way valve, and the water storage tank is connected to the three-way valve through a connecting pipe. When the temperature of the water outlet of the main unit reaches the set temperature, the water in the heating water tank is heated by the main unit while being pumped. to the storage tank. The disadvantage of this structure is that it is bulky and expensive. ...
