Description

Technical Field

[0001] The utility model relates to the technical field of air energy water heating systems, and in particular to an integrated air energy water heating storage device. Background Art

[0002] Air-energy water heaters absorb heat from the surrounding environment, and their working principle is based on the reverse Carnot cycle. An air-energy water heater compression heat pump host mainly consists of four parts: evaporator, compressor, condenser and expansion valve. The working fluid continuously completes the thermal cycle of evaporation (absorbing heat from the environment) → compression → condensation (releasing heat) → throttling → re-evaporation, thereby transferring heat from the environment to the water. Most of the existing air-energy water heaters are installed in a distributed manner, with the host and water tank separately set up. However, for some occasions with limited space, distributed installation will take up a lot of space and cannot meet normal installation requirements. In addition, the installation process requires the movement of the host and water tank, which is very laborious. In addition, most of the existing water tanks are used for heat exchange and storage of hot water. In order to ensure an uninterrupted supply of hot water, heat exchange is required at all times, resulting in low overall heat exchange efficiency. Utility Model Content
