Embodiment Construction

[0028] The system schematic diagram of the device is shown in Figure 1, which consists of two systems, one is a heat pump hot water system with a heat storage tank, including a compressor 1, a heat storage tank 3, a heat pump condenser 4, and a liquid reservoir 11. Throttle valve 12, evaporator 15, suction fan 13, air duct 16, wind direction switch 17, vapor-liquid separator 2, water mixing valve 6, water outlet valve 8, water replenishing valve 19, water supply pump 5, solenoid valve 7, 9, 10 composition.

[0029] In the hot water heating mode, the refrigerant vapor from the compressor 1 enters the heat pump condenser 4 through the solenoid valve 7 to release heat, and heats the cold water in the hot water storage tank. (The hot water storage tank and the condenser can be separated. can also be integrated). After condensing, the refrigerant enters the liquid receiver 11 through the solenoid valve 9, then flows through the throttle valve 12 to reduce the pressure, and then se...

Abstract

The invention discloses a hot pump water heating device with dehumidifying function and the control method. The device can realize the switching of two running modes of hot water producing and dehumidifying simultaneously or respectively; two systems of the device comprise a common compressor, a gas and liquid separator, a throttling device and an evaporator and other main devices, the hot pump hot water system utilizes the condensing heat energy generated by the circulation of the refrigerating fluid to obtain the hot water with high temperature, and utilizes a heat storing water tank to store the heat energy and provides life needed hot water on time; a refrigerating and dehumidifying system utilizes the cold energy provided by the refrigerating fluid to proceed the dehumidifying management to the room air, and realizes the dehumidifying management of the room air by the method of the air being heated by the condensing heat; the device can fulfill three working modes of solely dehumidifying, sole hot pump and hot pump air-condition, and the invention can satisfy the requirements for four seasons, in particular to the uses in bathrooms of families and hotels.

Description

technical field [0001] The invention relates to a heat pump water heater with dehumidification function and a control method thereof. Background technique [0002] With the rapid development of industry, the world's energy is increasingly tense, and the energy crisis has become one of the major issues that all mankind must face and must be resolved. Adopt high-efficiency and energy-saving household appliances as one of the six key energy-saving areas to focus on. [0003] Water heaters are one of the household appliances that consume a lot of energy. Electric water heaters and gas water heaters mainly consume high-grade energy such as electric energy, natural gas and gas. The development of solar water heaters has been greatly promoted, but they are limited by climate and installation conditions. At present, high-efficiency heat pump water heaters have become the main development direction. [0004] High-humidity environment can easily lead to the growth of bacteria, induc...
