The invention provides a heat pump system, an air conditioner and a control method for the heat pump system. The heat pump system includes a compressor with an exhaust port and an air intake port, an air inlet of a low pressure compression cylinder and / or an air inlet of a variable pressure compression cylinder Form the suction port, the air outlet of the variable pressure compression cylinder and / or the air outlet of the high pressure compression cylinder form the exhaust port; use the side heat exchange pipeline, heat source heat exchange pipeline and four-way valve, four ports of the four-way valve communicate with the suction port, the exhaust port, the first communication end of the use-side heat exchange pipeline and the first communication end of the heat source heat exchange pipeline; wherein, the first use-side heat exchanger and / or the second use-side The heat exchanger communicates with the four-way valve through the first communication end of the heat exchange pipeline on the use side; the first heat source heat exchanger and / or the second heat source heat exchanger communicate with the four-way valve through the first communication end of the heat source heat exchange pipeline. valve connected. Through the technical solution provided by the invention, the technical problem of low energy efficiency of the heat pump system in the prior art can be solved.
Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to a heat pump system, an air conditioner and a control method for the heat pump system. Background technique [0002] In recent years, the refrigeration system with double evaporating temperature has been widely studied in our country. The general heat pump system with double evaporating temperature includes two indoor heat exchangers and one outdoor heat exchanger. The system can set different evaporating temperatures, cooling in summer and heating in winter. [0003] However, the compressor of the above system has a single adjustment and only performs single-stage compression. In actual use, in the face of changing environmental conditions and indoor needs, the system needs to operate under variable conditions. At this time, the compressor cannot work under optimal conditions. Resulting in reduced energy efficiency of the compressor. Also, using only one heat source may resu...
