Method for defrosting the heat recovery system of the air conditioner

Abstract

The invention relates to the technical field of air conditioners and provides an air conditioner, a heat recovery system of the air conditioner and a heat recovery and defrosting method of the air conditioner. The heat recovery system of the air conditioner comprises a heat exchange water pipeline, a water pump, a heat accumulation water tank and a controller. The heat exchange water pipeline is arranged in an outdoor heat exchanger and connected with the water pump and the heat accumulation water tank to form a first water circulation circuit. By heat exchange between the heat exchange water pipeline and a refrigerant passage, heat of the outdoor heat exchanger is recovered, and accordingly energy sources are effectively saved. Further, by heat exchange between the outdoor heat exchanger and the heat exchange water pipeline in the first water circulation circuit, refrigeration effects of the outdoor heat exchanger can be improved. The first water circulation circuit is connected with a water inlet through a first switch valve. A temperature sensor for water temperature measurement and a water level sensor for water level measurement are arranged on the heat accumulation water tank. The controller controls starting and stopping of the water pump and controls on and off of the first switch valve according to received temperature and water level data and monitored operation conditions.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a defrosting method for a heat recovery system of an air conditioner. Background technique [0002] Various air-conditioning equipments in the air-conditioning field at present all are to discharge the heat in the house into the atmosphere through the condenser in the form of condensation heat. When the air conditioner is cooling, the heat of the condenser, that is, the outdoor heat exchanger, is not effectively utilized, and most of the heat is lost and wasted. This part of the heat is considerable, so it is necessary to recover the heat of this part of the condenser . At present, the recovery and utilization of condenser heat is mainly used in large-scale central air conditioner units, and there is almost no relevant research and system design for the utilization of condensation heat in room air conditioners. Moreover, since the condenser only exchanges heat with the...

Problems solved by technology

At present, the recovery and utilization of condenser heat is mainly used in large-scale central air conditioner units, and there is almost no relevant research and system design on the utilization of condensation heat in room air conditioners.

Moreover, since the condenser only exchanges heat between the refrigerant and the air, the heat exchange effect of the condenser is not good.
