Solution-assistant energy-storage domestic air conditioner

The invention belongs to the technical fields of refrigeration/heating and frost prevention and particularly relates to a solution-assistant energy-storage domestic air conditioner. The technical key point is that the air conditioner comprises a traditional indoor unit and an outdoor unit, wherein the outdoor unit also comprises a solution tank, a solution heat exchanger and a regenerator; the solution tank and a spray system which is mounted outside the outdoor hear exchanger form a circulation loop through a solution pipeline, a solution pump I and a solenoid valve I; a cycle fluid is a hygroscopicity saline solution; the spray system is capable of spraying the hygroscopicity saline solution on the surface of the outdoor heat exchanger; the solution tank, the solution heat exchanger and the regenerator are connected in sequence through a solution pipeline to form a regeneration circulation loop; a solution pump II and a solenoid valve II are mounted at the solution pipeline; a cycle fluid is the hygroscopicity saline solution. According to the solution-assistant energy-storage domestic air conditioner, when outdoor temperature is lower in winter, the air conditioner can run in a frostless way in the heating process, energy consumption can be reduced, and the system performance is improved.
