Description

Technical Field

[0002] Air-energy water heater, also known as "air source heat pump water heater", has a working principle very similar to that of an air conditioner. It uses a small amount of electrical energy to drive the compressor. The high-pressure liquid working fluid evaporates into gas in the evaporator after passing through the expansion valve and absorbs a large amount of heat energy from the air; the gaseous working fluid is compressed by the compressor into a high-temperature, high-pressure liquid, and then enters the condenser to release heat and heat the water.

The double water tank preheating energy-saving structure for an air-energy hot water system is spliced ​​by providing a double water tank structure for energy-saving preheating through relative sliding of mounting rails and connecting plates, thereby reducing the large space occupied by the double water tanks in the horizontal space, which increases the difficulty of installation. At the same time, a closed groove, a slide plate and a threaded rod are provided, which can limit the position of the positioning rod used to position the connecting plate, so that the double water tank structure can still be easily installed separately after separation, thereby improving the practicality of the device.

Due to the lack of filtering equipment, impurities in the water can easily enter the water tank. Frequent heating during operation may cause some components to burn out, which will increase the cost of subsequent maintenance to an extremely high level. In view of the above problems, the inventors have proposed a double-tank preheating device for an air-to-water water system to solve the above problems. Utility Model Content
