Description

Technical Field

[0001] The utility model belongs to the technical field of hot water equipment, and in particular relates to an air source hot water system. Background Art

[0002] A heat pump is an energy-saving device that can make heat flow from a low-level heat source to a high-level heat source. Air, soil, and water can all be used as low-level heat sources for heat pumps. Air resources are not restricted by the site and are available at any time. In addition, air heat source pumps are easy to install and use. Therefore, air heat source pump hot water systems have been widely promoted and applied in recent years due to their ease of use, energy saving, environmental protection, and high efficiency.

[0003] The air source hot water system uses the heat energy in the air to heat the water supply. When the hot water is supplied to the user through the system, its temperature will drop. In order to recycle the hot water with lower temperature and avoid energy waste, the air source hot water system introduces the concept of return water. The return water transports the cooled hot water from the user back to the heating water tank through the pipe, and heats it again to increase the water temperature and recycle it, saving energy and ensuring a continuous supply of hot water. However, when the temperature of the return water does not need to be heated, the system's reheating will cause energy waste. Utility Model Content
