Abstract

The invention provides a heat pump system, a defrosting method and a device. According to the heat pump system, exhaust heating equipment is arranged on a pipeline between a compressor and an oil separator and is used for heating liquid or gas which flows from the compressor to the oil separator again; a non-stop defrosting branch is arranged between a first pipeline and a second pipeline and is used for supplying the liquid or the gas heated by the exhaust heating equipment to a heat exchanger of an outdoor unit, so that the defrosting treatment on the heat exchanger of the outdoor unit is realized; the first pipeline is arranged between the exhaust heating equipment and the oil separator; and the second pipeline is arranged between the heat exchanger of the outdoor unit and a heat exchanger of an indoor unit, so that continuous heating of the heat pump system can be realized, the stop operation of the indoor heat exchanger is avoided during defrosting, the switching and restart of the compressor are avoided, the power consumption during defrosting is reduced, and the comfort is increased.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat pump system, a defrosting method and a device. Background technique [0002] In the current heat pump system, in the heating mode, the refrigerant in the heat exchanger of the outdoor unit absorbs heat from the outdoor air, then increases the pressure and temperature through the compressor, and discharges the heat from the outdoor side to the room to achieve the heating effect. However, when the outdoor temperature is too low and the humidity is high, the temperature of the refrigerant in the indoor heat exchanger needs to be lower than the temperature of the outdoor air, resulting in the gradual frosting on the surface of the outdoor heat exchanger and the loss of the heat absorption capacity of the outdoor heat exchanger. Gradually decreased, the heating effect is getting worse and worse. [0003] In order to ensure continuous heating operation, it is necessary...
