Description

Technical Field

[0001] This application relates to the field of water heaters, and more specifically, to an air source water heater with an expandable water tank structure. Background Technology

[0002] Air source heat pump water heaters use a small amount of electricity to drive the compressor. The high-pressure liquid working fluid evaporates into a gaseous state in the evaporator after passing through the expansion valve, absorbing a large amount of heat energy from the air. The gaseous working fluid is then compressed into a high-temperature, high-pressure liquid state by the compressor, and then enters the condenser to release heat and heat the water. The water in the tank flows through the condenser to complete the heat exchange. However, the existing water tank structure is fixed, and different capacity water tanks are required for different scenarios. Therefore, the adaptability of the water tank is low. To address this, we propose an air source heat pump water heater with an expandable water tank structure. Utility Model Content
