Abstract

The invention discloses a heat pump air conditioner and a control method thereof, and belongs to the field of heat pump air conditioner devices and control methods thereof. The heat pump air conditioner is designed in order to solve the problems that an existing device is large in occupied space and the like. The heat pump air conditioner comprises a compressor, an indoor heat exchanger and an outdoor heat exchanger and further comprises an instant water heater. The instant water heater comprises a hollow cavity and a water pipe arranged in the cavity. One end of the water pipe penetrates out of the cavity to form a water inlet, and the other end of the water pipe penetrates out of the cavity to form a water outlet. A refrigerant inlet and a refrigerant outlet are formed in the cavity, the refrigerant inlet is connected to an exhaust port of the compressor through a pipeline, and the refrigerant outlet is connected to a pipeline between the indoor heat exchanger and the outdoor heat exchanger. Refrigerant flowing through the cavity is used for heating water flowing through the water pipe. The heat pump air conditioner comprises the instant water heater, a water tank does not need to be arranged, space is saved, and cost is low. The control method of the heat pump air conditioner can utilize the refrigerant to heat water in the instant water heater, and the heat pump air conditioner is convenient to use and good in heating effect.

Description

technical field [0001] The invention relates to a heat pump air conditioner and a control method for the heat pump air conditioner. Background technique [0002] A heat pump air conditioner is an electrical appliance that combines the functions of an air conditioner and a water heater. It has strong functions and is easy to use. [0003] A hot water tank needs to be provided in the existing heat pump air conditioner for heating and storing hot water. The volume of the hot water tank is usually relatively large, the required installation space is large, and it is not easy to install, the cost is high, and the system is complicated. There will be heat loss during the energy storage process of the hot water tank, resulting in relatively large power consumption. Contents of the invention [0004] One object of the present invention is to propose a heat pump air conditioner that saves space and reduces costs. [0005] Another object of the present invention is to provide a c...
