Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
As shown in Figure 1 and Figure 2, a kind of source pump, including compressor 1, oil eliminator 2, condenser the 3, first ball valve 4, device for drying and filtering 5, electric expansion valve the 6, second ball valve 7, parallel two phase flow distribution formula vaporizer 8, oil return solenoid valve 9, jet pump 10, compressor input ball valve 11, oil return corner-kick valve 12, return filter 13.Described compressor 1 connects described oil eliminator 2, described oil eliminator 2 connects described ball valve 4, described ball valve 4 connects described device for drying and filtering 5, described device for drying and filtering 5 connects described electric expansion valve 6, described electric expansion valve 6 connects described ball valve 7, described ball valve 7 connects described parallel two phase flow distribution formula vaporizer 8, and described parallel two phase flow distribution formula vaporizer 8 connects described compressor 1 and forms the first loop.Described compressor 1 connects described oil eliminator 2, and the refrigeration oil that described oil eliminator 2 separates connects with described return filter 13 through described oil corner-kick valve 12, enters described compressor 1 and forms second servo loop.The internal refrigeration oil got off of described parallel two phase flow distribution formula vaporizer 8 is collected to described compressor input ball valve 11 through described jet pump 10 injection with described condenser 3 gases at high pressure by described solenoid 9, enters described compressor 1 and forms tertiary circuit.Described parallel two phase flow distribution formula vaporizer 8 includes parallel two phase flow allotter 15, heat exchanger tube 16, secondary parallel two phase flow distribution plate 17 and cylinder 18.It is provided with gas register mode area in described parallel two phase flow allotter (15).The internal oil screen being provided with preliminary filtering high temperature high-pressure gaseous coolant and refrigeration oil of described oil eliminator 2.The internal horizontal oil screen being provided with second time filtering high temperature high-pressure gaseous coolant and refrigeration oil of described oil eliminator 2.Described compressor 1 and described electric expansion valve 6 are controlled by switch board 14.Described first loop, described second servo loop, described tertiary circuit are closed circuit.Expansion valve throttling gas-liquid two-phase cold-producing medium uniform distribution is realized by three communication loop loops, thus solve and utilize condenser to do the internal complete single liquid refrigerants of the supercool vaporizer of liquid to be uniformly distributed, heat exchanger area is avoided not to be fully utilized, and then improve effective work area of condensing heat exchanger, it is to avoid cause energy waste.
When unit is in load running, low-temp low-pressure gaseous coolant is compressed by compressor 1 and forms high pressure gaseous coolant, high pressure gaseous coolant enters oil eliminator 2 interior sealed space with refrigeration oil mixture, after being filtered by oil screen, after high pressure gaseous coolant and refrigeration oil again pass by horizontal oil screen, the refrigeration oil entrance compressor 1 separated forms circulation and plays lubrication.Meanwhile, High Temperature High Pressure coolant cooling water release heat in condenser 3 copper pipe is changed into and is condensed into the liquid of middle temperature high pressure, the biphase coolant of gaseous state.Low-pressure low-temperature air-liquid state coolant enters parallel two phase flow allotter 15, gas " register mode area " is had in parallel two phase flow allotter 15, through heat exchanger tube 16 by the storage distribution of shwoot refrigerant gas, then make air-liquid uniform distribution by secondary parallel two phase flow distribution plate 17.Thus solve and utilize condenser to do the internal complete single liquid refrigerants of the supercool vaporizer of liquid to be uniformly distributed, it is to avoid heat exchanger area is not fully utilized, and then improves effective work area of condensing heat exchanger, it is to avoid cause energy waste.Entering parallel two phase flow distribution formula vaporizer 8, through the running of parallel two phase flow distribution formula vaporizer 8, low-pressure low-temperature two-phase mixture coolant absorbs heat from the chilled water flowing through evaporator shell in copper body 18, produces refrigeration to room and reduces the purpose of room temperature.Low-pressure low-temperature coolant sucks compressor 1 after being vaporizated into low temperature low pressure gas, and cold-producing medium forms circulation also into compressor 1 simultaneously.Thus solve vaporizer rely on single-phase flow uniform distribution cold-producing medium, and solve increase supercool formation single-phase liquid realize distributed uniform, it is to avoid condenser copper tube area loss.Parallel two phase flow distribution formula method is assigned to outside each evaporation tube to be formed dry blowing district, and gas-liquid two-phase distribution is uniform, so that the heat exchange efficiency of vaporizer promotes 10%.Also stopped some refrigerant fully to be evaporated and make liquid refrigerant directly be sucked by compressor and cause compressor band liquid to run and damage compressor.
This utility model one source pump has and is capable of expansion valve throttling gas-liquid two-phase cold-producing medium uniform distribution, and then improves effective work area of condensing heat exchanger, it is to avoid cause the advantages such as energy waste.
