The Research On Centre Supplement Gas Scroll Compressor And Their Circulatory System

The scroll compressor having centre supplement gas being able to take the system be effective under low temperature environment to change air source heat pump to heat up a function and to run reliability. Systematic research of fever of the main body of a book being compressed according to centre supplement gas scroll compressor operating principle and accurate two stage pump current situation, has adopt theoretical analysis, has optimized with method of integration of simulated calculation with experiment verification, has carried out detailed research and analysis on the function taking lightning to send out the implement centre supplement gas scroll compressor.The research background the main body of a book has been set forth heating up the pump air-conditioning use eddy compression engine, has analysed the current situation fever of issuing at home and abroad to the eddy compression engine and the low temperature environment pump system research , has summed up the eddy compression engine effect in heat pump system; Have set forth centre supplement gas heat pump air-conditioning system principle , the structure characteristic having analysed the centre supplement gas eddy compression engine; Have brought forward the tradition supplement gas structure different from new model to supplement gas and have analysed whose respective excellent shortcoming; Have built mathematics equation having described whose performance data.Have set forth the air-conditioning heat pump system operational feature under low temperature air source environment , have suggested that the implement queen has improved hot COP of system increasing setting up economy, and have compared flashing to send out implement system and the systematic characteristic of economy implement; That the two stage compresses heat pump circulation to certainty , increase has made a compression engine increase by a supplement gas compression process after setting up the economy implement, compared with routine air source fever pump circulation; Have taken taking lightning to send out the implement eddy compression engine heat pump system as example , have analysed the mathematic model having increased the course of work, and building-up setting up the tonifying Qi mouth queen eddy compression engine applying to lightning send out implement heat pump system detailedly; center supplement gas has carried out heating power analysis on to taking lightning to send out systematic centre of implement , hasascertained the heat content value that every state puts , the main function index having reached an aircraft crew.Have carried out the analysis secretly scheming against on the mathematics simulation adding supplemental the integrity stream , have reached an impact of the location assisting an air inlet over lightning hair implement system function with what be chosen a model machine for the example; The simulated calculation bear fruit sending out implement front orificing system and compressing system imitate single stage has carried out comparison on lightning , has ascertained system best flashing to send out an implement and compressing single stage being sure to change area; Depend on the formula testing that the data basis intends to have agreed well with out the electricity efficiency applying to lightning send out implement fever pump system on that; Take flashing to send out implement type centre supplement gas system as basis, reference Xi'an Jiaotong University has developed out the eddy compression engine flashing to send out systematic prototype of implement heat pump machine, operation and working condition having checked prototype machine under low temperature working condition, have joined a checkout being changed to manufacture queen prototype machine the compression engine function, has tested the hot system function that prototype machine goes down in low temperature working condition all round , has made the inherent law flashing to send out the implement centre supplement gas heat of compressing pump system aircraft crew clear.
