Abstract
The utility model discloses an air conditioner which can heat with high efficiency in cold season. The air conditioner comprises a program controller, a heat pump, a heat exchange assembly for antifreezing liquid, a heat exchange assembly for indoor air and a heat exchange assembly for outdoor air. The air conditioner can substantially improve the heating capacity in the cold season and the refrigeration capacity in hot season; in the heating process of the air conditioner, if the air conditioner stops working, the antifreezing liquid in an antifreezing liquid box continuously absorbs heat in air and provides more heat for next heating; in the heating process of the air conditioner, after the air conditioner begins working, the antifreezing liquid in the antifreezing liquid box gradually declines; the heat transfer of the air to the antifreezing liquid box is accelerated; as two capillary throttle valves are used in the heating process, the temperature of the refrigerant is lower; and at this time, a first outdoor heat exchange coil pipe absorbs more heat from the antifreezing liquid, thereby greatly improving the heating effect of the air conditioner in cold season.
