The invention discloses an air-energy water heater set which comprises a shell, left and right evaporators arranged on the left and right sides of the shell, a ventilating fan arranged on the top of the shell, a compressor arranged in the cavity inside the shell, a heat exchanger, a water inlet hole which is arranged in the front surface of the shell and communicated with a water inlet of the heat exchanger, and a water outlet hole communicated with a water outlet of the heat exchanger, wherein an outlet of the compressor is communicated with a coolant inlet of the heat exchanger; a coolant outlet of the heat exchanger is communicated with an inlet of a thermoexpansion valve; an outlet of the thermoexpansion valve is communicated with inlets of the evaporators; and outlets of the evaporators are communicated with a coolant inlet of the compressor. The air-energy water heater set has the advantages of high heat exchange efficiency, high heat exchange quantity, long service life and high safety and reliability.

Air-energy water heater set

The utility model discloses an air energy water heater which comprises a compressor, a steam-water heat exchanger, a throttling element, a fin heat exchanger, a draught fan, a vapor liquid separator and a connecting pipeline. The fin heat exchanger comprises a first fin heat exchanger and a second fin heat exchanger, wherein the first fin heat exchanger and the second fin heat exchanger are arranged side by side and are connected in series, and the draught fan is arranged on the outer side of the second fin heat exchanger. The throttling element is in series connection between the first fin heat exchanger and the second fin heat exchanger. The steam-water heat exchanger is of a brazed plate heat exchanger, a double-pipe heat exchanger, a shell and tube heat exchanger, or a spiral evaporating pipe. Thus, not only is the performance coefficient of the air energy water heater improved, but also frostless operation of the air energy water heater is achieved, and therefore the defects of a traditional air energy water heater are overcome.
