Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as figure 1 The shown compressor includes a low-pressure stage body 1 and a high-pressure stage body 2, the low-pressure stage body 1 has a low-pressure stage suction port 11 and a low-pressure stage exhaust port 12, and the high-pressure stage body 2 has a high-pressure stage suction port 21. There is a communication pipeline 3 between the low-pressure stage exhaust port 12 and the high-pressure stage suction port 21, the low-pressure stage suction port 11 communicates with the low-pressure gas source, and the high-pressure stage suction port 21 It has a first state communicating with...

Abstract

The invention provides a compressor with a two-stage exhaust function and an air conditioning system. The compressor comprises a low-pressure stage machine body and a high-pressure stage machine body,the low-pressure stage machine body is provided with a low-pressure stage suction port and a low-pressure stage exhaust port, the high-pressure stage machine body is provided with a high-pressure stage suction port, and a communicating pipeline is arranged between the low-pressure stage exhaust port and the high-pressure stage suction port. According to the compressor with the two-stage exhaust function and the air conditioning system, the communicating pipeline is arranged, the problem of high-pressure stage exhaust temperature increase caused by the fact that low-pressure stage discharged gas flows through a motor is avoided, meanwhile gas suction sources of the high-pressure stage machine body can be switched according to the demands, the exhaust pressure of the compressor is adjusted,the states of resource waste such as overcompression caused by rated pressure ratios in the prior art is overcome, at the same time, the exhaust flow under the same exhaust pressure can be increasedwhen the low-pressure stage machine body and the high-pressure stage machine body work simultaneously, the output capacity of the compressor is enhanced, and therefore the application range of the compressor is increased.

Description

technical field [0001] The invention relates to the technical field of compression devices, in particular to a compressor and an air-conditioning system with two-stage exhaust functions. Background technique [0002] The working principle of the existing single-unit two-stage screw compressor is that two pairs of screw rotors are connected in series through a coupling, and the refrigerant enters the low-pressure stage rotor cavity through the compressor suction port to be compressed, and then enters the high-pressure stage rotor cavity through the motor cavity to complete the process. compressed, and finally discharged as ultra-high pressure gas. The main means is to compress low-pressure refrigerant into ultra-high-pressure gas through two-stage compression technology, as shown in the figure. It is often used in ultra-high temperature heat pump and ultra-low temperature refrigeration technology. [0003] When a single-unit two-stage compressor is used in a heat pump unit,...
