Abstract
A steam compressing type refrigeration system, which contains single refrigeration type air conditioner, car air conditioner, refrigerator, freezer, showing cabinet with refrigeration, ice maker, cold water dispenser, refrigerator car, refrigeration chamber. Said invention consisting of compressor, condenser, evaporator, throttle, and connection pipe, the gas and liquid separator set between throttle and evaporator for separating gas state refrigerant and making the evaporator entered all refrigerant converted into liquid state refrigerant to raise the heat conduction performance, improve refrigeration effect of compressor and raise service life of compressor.
Description
Technical field
The present invention is a kind of vapour compression refrigeration system, and it comprises that single cold type air regulator (equipment), air conditioner in car, refrigerator, household freezer, frozen and refrigerated display case, ice machine, Cold Drinking Water machine, refrigerator car, freezing-cooling storeroom etc. adopt the device of steam compression type refrigeration.
Background technology
Existing vapour compression refrigeration system, mainly form by compressor, condenser, evaporimeter, throttling arrangement and tube connector etc., its shortcoming is to become low-temp low-pressure gas, liquid mix refrigerant by the high pressure liquid refrigerant after the condenser condenses through the throttling arrangement throttling, enter evaporator evaporation together, cause the heat transfer property of evaporimeter to descend, pressure drop 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 this invention is to provide a kind of reasonable in designly, can effectively improve the vapour compression refrigeration system of refrigerating capacity and Energy Efficiency Ratio.
The present invention is a vapour compression refrigeration system, comprise compressor, condenser, evaporimeter, throttling arrangement and tube connector, it is characterized in that being provided with gas-liquid separator between throttling arrangement and the evaporimeter, the import of gas-liquid separator is connected by tube connector with the outlet of throttling arrangement, the liquid refrigerant outlet of gas-liquid separator is connected by tube connector with the import of evaporimeter, and the gaseous refrigerant outlet of gas-liquid separator is connected by tube connector with muffler.
The present invention produces liquid refrigerant after the throttling arrangement throttling a large amount of gaseous refrigerants, obtain separating by gas-liquid separator, it all is liquid making the cold-producing medium that enters evaporator evaporation, directly get back to compressor through the gaseous refrigerant that gas-liquid separator separates is come out by tube connector and muffler, and do not enter evaporimeter, improved the heat exchange performance of evaporimeter significantly.
The present invention 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 enter evaporator evaporation, because being liquid refrigerant, the function of evaporimeter becomes gaseous refrigerant by the be cooled heat of vaporization of medium of absorption, the medium temperature that is cooled is reduced, the evaporation and gaseous refrigerant not only can not absorb heat in evaporimeter, and because the heat transfer property of gaseous refrigerant is far below the heat transfer property of liquid refrigerant, so gas, the heat transfer property of liquid mix refrigerant is lower than liquid refrigerant, and big more its heat transfer property of the ratio of gaseous refrigerant is low relatively more, the present invention passes through gas-liquid separator, it all is liquid making the cold-producing medium that enters evaporimeter, thereby has improved the average heat transfer performance of evaporimeter.
2, because the volume of the gaseous refrigerant of equal in quality is much larger than liquid refrigerant, throttling arrangement is exported to the tube connector and the interior gas of evaporimeter of evaporator in the prior art, the flow velocity of liquid mix refrigerant is its flow velocity height under the equal in quality flow, its pressure drop is also big, corresponding average evaporating temperature is also higher, the present invention separates a large amount of gaseous refrigerants that the throttling arrangement throttling produces by gas-liquid separator, therefore the gas-liquid separator liquid refrigerant outlet is lower under the equal in quality flow to the tube connector of evaporator and the cold-producing medium flow velocity in the evaporimeter, 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
Accompanying drawing is vapour compression refrigeration system figure of the present invention.
The specific embodiment
The present invention is mainly by compressor 1, condenser 2, evaporimeter 3, throttling arrangement 4, place the compositions such as gas-liquid separator 5 between throttling arrangement 4 and the evaporimeter 3, the import of gas-liquid separator 5 is connected by tube connector 8 with the outlet of throttling arrangement 4, the liquid refrigerant outlet of gas-liquid separator 5 is connected by tube connector 9 with the import of evaporimeter 3, the gaseous refrigerant outlet of gas-liquid separator 5 is connected by tube connector 11 with muffler 10, compressor 1 outlet is connected by blast pipe 6 with condenser 2 imports, condensator outlet is connected by tube connector 7 with throttling arrangement 4 imports, and evaporimeter 3 outlets are connected by muffler 10 with compressor 1 import.
During work, compressed machine 1 is collapsed into the gaseous refrigerant of HTHP, enter condenser 2 condensations by blast pipe 6 and become high pressure liquid refrigerant, high pressure liquid refrigerant enters throttling arrangement 4 throttlings becoming low-temp low-pressure gas by tube connector 7, the liquid mix refrigerant, entering gas-liquid separator 5 through tube connector 8 separates, isolated gaseous refrigerant is entered muffler 10 by tube connector 11, liquid refrigerant enters evaporimeter 3 heat absorption evaporations through tube connector 9 becomes gaseous refrigerant, gaseous refrigerant and the gaseous refrigerant of separating from gas-liquid separator 5 are got back to compressor 1 by muffler 10, finish kind of refrigeration cycle.
The present invention is owing to improved the average heat transfer performance of evaporimeter 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.
