Embodiment Construction

[0037] Such as Figure 1-6 As shown, the present invention provides a heat pump system, which includes:

[0038] The compressors with more than two stages, the evaporator 5 and the condenser 6 also include a flash device, and the flash device can introduce the gas generated by the flash into the compressors with more than two stages, and in at least two phases At least one cooler is also arranged between the adjacent compressors, which can be used to cool the exhaust gas of one of the two adjacent compressors, and then enter it together with the gas generated by the flash device. Compression takes place in the other of the two adjacent compressors.

[0039] In the present invention, at least one cooler is arranged between two adjacent compressors in the compressors with more than two stages in the system for supplementing air and increasing enthalpy, so as to cool down the refrigerant compressed by the lower-pressure compressor, and then Entering the higher pressure compress...

Abstract

The invention provides a heat pump system and an air conditioner. The heat pump system comprises two or more stages of compressors, an evaporator (5) and a condenser (6), and further comprises a flashdevice, the flash device can guide gas generated by flash into the two or more compressors, at least one cooler is further arranged between at least two adjacent compressors and can be used for cooling the exhaust gas of one compressor in the two adjacent compressors, and then enters the other one of the two adjacent compressors to be compressed together with the gas generated by flash generationof the flash device. According to the heat pump system and the air conditioner, the suction temperature of all the compressors except the lowest-stage compressor can be reduced, the final exhaust temperature of a compression system is reduced, the energy consumption of the compressor is reduced, so that the heat energy efficiency of the heat pump system is improved.

Description

technical field [0001] The invention belongs to the technical field of heat pumps, and in particular relates to a heat pump system and an air conditioner. Background technique [0002] As a new energy-saving and environmental protection technology, heat pump technology can transfer heat energy from low-temperature heat sources to high-temperature heat sources, which is of great significance to energy conservation and ecological environment protection, especially when the energy crisis and global warming are becoming more and more serious. , heat pump technology has also become the focus of everyone's attention and research, and the research, application and promotion of various heat pump technologies have also received considerable attention. [0003] As a common heat pump technology, the technology of replenishing air and increasing enthalpy is mainly used in heat pump systems with two-stage or multi-stage compression. It can not only improve the energy efficiency of the he...
