What is an air-assisted heat pump system and an air-assisted heat pump water heater?

The invention relates to an air energy heat pump system and an air energy heat pump water heater, belonging to the technical field of air energy heat pump. The air energy heat pump system comprises a main control board and an electric energy metering module, which is connected between the power supply and the main control board and is used for detecting the current electricity consumption of the air energy heat pump system, and inputting the detected current electricity consumption into the main control board. The technical scheme of the utility model can save the space of the main control board by placing the electric energy metering module outside the main control board, and can decide whether to install the electric energy metering module according to the user's choice, the utility model can save the cost of installing the electric energy metering module on the main control board.
