Multi-jet cryogenic heat pump energy-saving system with an injector

Abstract

The invention discloses a multi-connected jet low-temperature heat pump energy-saving system with an injector, which comprises a compressor, a four-way valve, a multi-connected outdoor heat exchangergroup and an indoor heat exchanger. The outdoor heat exchanger module 1, the outdoor heat exchanger module 2 and the outdoor heat exchanger module 3 are all connected with one end of the indoor heat exchanger. The outdoor heat exchanger module 1 and the outdoor heat exchanger module 2 are communicated with the interface C of the four-way valve; The outdoor heat exchanger module 3 is communicated with the interface C of the four-way valve and a first electromagnetic valve is arranged between the interface C and the outdoor heat exchanger module 3; The outdoor heat exchanger module 3 is communicated with the inlet end of the injector and a second electromagnetic valve is arranged between the outdoor heat exchanger module 3 and the inlet end of the injector. The interface D of the four-way valve is communicated with the drainage end of the injector; The input port of the compressor is communicated with the diffuser end of the injector. Making full use of the thermodynamic working principle of the ejector, this paper designs a unique multi-connected cryogenic heat pump air conditioner, which has the function of pressurizing the return air.

Description

technical field [0001] The invention provides a household or commercial multi-connected multi-connected low-temperature heat pump energy-saving device with an ejector, in particular, it relates to a device for increasing the suction pressure of a multi-connected heat pump air-conditioning compressor and reducing the energy consumption of the air-conditioning system installation.

[0002] With the development of society, the application of air conditioners is becoming more and more popular, and the energy saving of air conditioning systems has attracted more and more attention, especially the application of multi-connected air conditioners has become more and more popular. Therefore, how to further reduce the energy consumption of multi-connected air conditioners It is very necessary. Secondly, the existing multi-connected air-conditioning system has high energy consumption and needs to adapt to practical problems such as low ambient temperature conditions as low as -25 degrees. The traditional multi-connected air-conditioning system uses simple air-conditioning compression The machine return air pipe is used to pressurize the return air, which leads to insufficient return air pressure of the multi-connected air conditioning system in low temperature environment, high compression ratio of the compressor and poor refrigeration performance
