Abstract

The embodiment of the invention provides a heat pump system, and relates to the technical field of heat pumps. The problem that a four-way valve is unable to reverse or the four-way valve is damaged due to the fact that liquid exists in a traditional heat recovery heat pump system can be solved. A gas-liquid separator, a compressor, a first outdoor heat exchanger, an outdoor throttling element anda first water module which are located in the heat pump system sequentially communicate with one another to form a closed flow path, and a first indoor unit is connected to the two ends of the firstwater module in parallel; a four-way valve is connected with the interior of the closed flow path in series, one end of a first valve is connected to a connecting pipeline of the C end of the four-wayvalve and the first outdoor heat exchanger, and the other end of the first valve is connected to the first water module; and one end of a second valve is connected to a connecting pipeline of an outlet of the compressor and the D end of the four-way valve, and the other end of the second valve is connected to a connecting pipeline of the first valve and the first water module. The heat pump system is used for refrigerating and heating.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to a heat pump system. Background technique [0002] At present, the frequency conversion multi-connected heat recovery heat pump system has become a research hotspot in the field of heat pumps, and major domestic air-conditioning manufacturers are also committed to the development of this type of model. The traditional heat pump system can generally realize four operation modes: cooling operation mode, heating operation mode, cooling and heating at the same time and cooling as the main operation mode, cooling and heating at the same time and heating as the main operation mode, the above four modes It mainly depends on the switching of more than two four-way valves in the outdoor unit. This multi-four-way valve system may cause the gaseous refrigerant to condense into a liquid state, and there is a dead cycle in the four-way valve; when the four-way valve needs to change directio...
