Description
Technical field
The utility model relates to the cold and hot source control system of a kind of building.
Background technology
Existing building Refrigeration Technique; Mainly be made up of compressor, condensing unit, vaporising device, throttling arrangement and tube connector etc., its shortcoming is to become low-temp low-pressure gas, liquid mix refrigerant through the condensed high pressure liquid refrigerant of condensing unit through the throttling arrangement throttling, gets into the vaporising device evaporation together; Cause the heat transfer property of vaporising device to descend; Pressure increases, and average evaporating temperature raises, and the refrigerating capacity of refrigeration system and Energy Efficiency Ratio descend.
Summary of the invention
The purpose of the utility model is: provide a kind of building cold and hot source control system, with solve prior art exist refrigerating capacity and Energy Efficiency Ratio low technological deficiency.
Reaching the technical scheme that the purpose of the utility model takes is: the cold and hot source control system of a kind of building; Comprise compressor, condensing unit, vaporising device, throttling arrangement and tube connector; It is characterized in that: be provided with gas-liquid separation device between throttling arrangement and the vaporising device; The import of gas-liquid separation device is connected through tube connector with the outlet of throttling arrangement; The liquid refrigerant outlet of gas-liquid separation device is connected through tube connector with the import of vaporising device, and the gaseous refrigerant outlet of gas-liquid separation device is connected through tube connector with muffler.
The utility model produces liquid refrigerant after the throttling arrangement throttling a large amount of gaseous refrigerants; Obtain separating through gas-liquid separation device; It all is liquid making the cold-producing medium that gets into the vaporising device evaporation; Gaseous refrigerant through gas-liquid separation device is separated is directly got back to compressor through tube connector and muffler, and does not get into vaporising device, has improved the heat exchange performance of vaporising device significantly.
The utility model compared with prior art has following advantage and good effect.
1, a large amount of gaseous refrigerants that produce through the throttling arrangement throttling in the prior art and liquid refrigerant are mixed and get into the vaporising device evaporation; Because being liquid refrigerant, the function of vaporising device becomes gaseous refrigerant through the be cooled heat of vaporization of medium of absorption; The medium temperature that is cooled is reduced; And the gaseous refrigerant evaporation of in vaporising device, not only can not absorbing heat, and since the heat transfer property of gaseous refrigerant far below the heat transfer property of liquid refrigerant, so the heat transfer property of gas, liquid mix refrigerant is lower than liquid refrigerant; And bigger its heat transfer property of the ratio of gaseous refrigerant is low relatively more; The utility model is through gas-liquid separation device, and it all is liquid making the cold-producing medium that gets into vaporising device, thereby has improved the average heat transfer performance of vaporising device.
2, since the volume of the gaseous refrigerant of equal in quality much larger than liquid refrigerant; To be exported to flow velocity its flow velocity under the equal in quality flow of gas, liquid mix refrigerant in tube connector and the vaporising device of vaporising device import high for throttling arrangement in the prior art; Its pressure drop is also big; Corresponding average evaporating temperature is also higher; The utility model separates a large amount of gaseous refrigerants that the throttling arrangement throttling produces through gas-liquid separation device, so the tube connector of gas-liquid separation device liquid refrigerant outlet to vaporising device import and the cold-producing medium flow velocity in the vaporising device are lower under the equal in quality flow, and its pressure drop is also less; Corresponding average evaporating temperature is also lower, has increased the temperature difference that is cooled between medium temperature and the average evaporating temperature.
Description of drawings
Fig. 1: be the building Cooling and Heat Source control system diagram of the utility model.
The specific embodiment
The architectural feature of the utility model more at large is described below in conjunction with accompanying drawing.
The utility model mainly by compressor 1, condensing unit 2, vaporising device 3, throttling arrangement 4, place gas-liquid separation device 5 between throttling arrangement 4 and the vaporising device 3 etc. to form; The import of gas-liquid separation device 5 is connected by tube connector 8 with the outlet of throttling arrangement 4; The liquid refrigerant outlet of gas-liquid separation device 5 is connected by tube connector 9 with the import of vaporising device 3; The gaseous refrigerant outlet of gas-liquid separation device 5 is connected by tube connector 11 with muffler 10; Compressor 1 outlet is connected through blast pipe 6 with condensing unit 2 imports; The condensing unit outlet is connected through tube connector 7 with throttling arrangement 4 imports, and vaporising device 3 outlets are connected through muffler 10 with compressor 1 import.
During work; Be collapsed into the gaseous refrigerant of HTHP through compressor 1; Getting into condensing unit 2 condensations through blast pipe 6 becomes high pressure liquid refrigerant, and high pressure liquid refrigerant gets into throttling arrangement 4 throttlings becoming low-temp low-pressure gas, liquid mix refrigerant through tube connector 7, gets into gas-liquid separation device 5 through tube connector 8 and separates; Isolated gaseous refrigerant is got into muffler 10 through tube connector 11; Liquid refrigerant gets into vaporising devices 3 heat absorption evaporations through tube connector 9 becomes gaseous refrigerant, and gaseous refrigerant and get back to compressor 1 through muffler 10 from the gaseous refrigerant that gas-liquid separation device 5 is separated is accomplished kind of refrigeration cycle.
The utility model is owing to improved the average heat transfer performance of vaporising device 3 and reduced average evaporating temperature; Increased the temperature difference that is cooled between medium temperature and the average evaporating temperature; Refrigerating capacity and Energy Efficiency Ratio under various working conditions are greatly improved; Improve the cooling effect of compressor simultaneously, improved the service life of compressor.
