Heat pump hot water system is a hot water supply system that uses air, groundwater, and surface water as low-temperature heat sources, water as the heat transfer medium, and steam compression heat pump technology to heat domestic hot water. The basic system schemes of using a heat pump to supply hot water include direct heating, indirect heating, and mixed heating. Conventional heat pump water heater, including ground source heat pump, water source heat pump, air-source heat pump, and other mechanical compression heat pump forms, as air conditioning technology, its application has been very common.

How about the research and application of heat pump hot water systems at home and abroad?
What is the working principle of a heat pump water heater?
What are the types of heat pump hot water production systems?
At present, the common way of using a heat pump to make hot water is a heat pump water heater, that is, a single heat pump water heater set for a single room or a household to supply hot water. Conventional heat pump water heaters have become popular in high energy-consuming countries such as Europe and the United States, and even in developing countries such as South Africa, they have a 16 percent market share. Domestic heat pump water heaters have also been reported, the research and popularization of heat pump technology as a large-scale hot water supply system need to be deepened and improved.
There are two basic systems of heating water by heat pump: direct heating and indirect heating. Option one, direct heating, is a heat pump condenser directly placed in the water tank to heat cold water, compared with option two, there is less a heat exchanger, so the heat transfer efficiency is relatively larger, the highest water temperature can be a little higher. The storage tank shall be combined with the heat pump and shall not be suitable for modification of the existing heat pump. The supply of hot water shall be powered by the water pump, which to some extent increases the power consumption and noise of the system. Scheme 2, the indirect heating method, is to transfer the condenser heat to the intermediate medium. One more heat exchanger in the system. Indirect heat transfer has heat loss, which reduces the heating efficiency of the whole system to a certain extent. Plan three, mixed heating, with a pump forced water circulation in the tank through the condenser, enhances the heat transfer efficiency.
Conventional heat pump water heaters, including ground-source heat pumps, water-source heat pumps, air-source heat pumps, and other forms of mechanical compression heat pumps, as air-conditioning technology, its application has been widely used in heat pump hot water system according to the different heat source of equipment heat pump hot water system is divided into the following four kinds: air source heat pump hot water system, water source heat pump hot water system, ground source heat pump hot water system, mixed heat pump hot water system.
