Description

The refrigeration system of pump type heat central authorities and family formula center air conditioning equipment
Technical field
The present invention relates to the refrigeration system of a kind of pump type heat central authorities and family formula center air conditioning equipment, belong to the manufacturing technology field of the apparatus of air conditioning.
Background technology
The refrigeration system of existing pump type heat central authorities and family formula center air conditioning equipment, mainly by compressor, outdoor heat converter, indoor heat converter, throttling arrangement, composition such as four-way electromagnetic reversing valve and tube connector, its shortcoming is to become low-temp low-pressure gas by the condensed high pressure liquid refrigerant of outdoor (interior) heat exchanger through the throttling arrangement throttling, the liquid mix refrigerant, (outward) heat exchanger evaporation in the inlet chamber together, cause the heat transfer property of indoor (outward) heat exchanger to descend, pressure drop increases, average evaporating temperature raises, and the refrigeration of refrigeration system (heat) amount 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 refrigeration (heat) amount and the pump type heat central authorities of Energy Efficiency Ratio and the refrigeration system of family formula center air conditioning equipment.
The present invention is the refrigeration system of pump type heat central authorities and family formula center air conditioning equipment, comprise compressor, outdoor heat converter, indoor heat converter, throttling arrangement, four-way electromagnetic reversing valve and tube connector, it is characterized in that being respectively equipped with gas-liquid separator between throttling arrangement and outdoor heat converter and the indoor heat converter, the two ends of throttling arrangement are connected with the import of gas-liquid separator respectively, the liquid refrigerant outlet of two gas-liquid separators is connected with outdoor heat converter and indoor heat converter one end respectively, and the gaseous refrigerant outlet of two gas-liquid separators is connected by check valve with the other end of outdoor heat converter and indoor heat converter respectively.
The present invention produces liquid refrigerant after the throttling arrangement throttling a large amount of gaseous refrigerants, obtain separating by gas-liquid separator, the cold-producing medium that makes (outward) heat exchanger evaporation in the inlet chamber all is liquid, directly get back to compressor through the gaseous refrigerant that gas-liquid separator separates is come out by check valve and tube connector, and (outward) heat exchanger in the inlet chamber has not improved the heat exchange performance of indoor (outward) heat exchanger significantly.
The present invention compared with prior art has following advantage and good effect.
1, in the prior art through a large amount of gaseous refrigerants that the throttling arrangement throttling produces are mixed inlet chamber with liquid refrigerant in (outside) heat exchanger evaporates, flash to and be gaseous refrigerant by the absorption medium heat that is cooled because the function of indoor (outward) heat exchanger is a liquid refrigerant, 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, the cold-producing medium that makes (outward) heat exchanger in the inlet chamber all is liquid, thereby has improved the average heat transfer performance of indoor (outward) heat exchanger.
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 indoor (outward) heat exchanger of indoor (outward) heat exchanger inlets 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 and the cold-producing medium flow velocity in indoor (outward) heat exchanger of indoor (outward) heat exchanger inlets, 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.

Fig. 2 is the refrigerating system figure of cold (heat) of the present invention water type central authorities and family formula center air conditioning equipment.
Fig. 3 drags the refrigerating system figure of multiple user center air conditioning equipment for pump type heat one of the present invention.
Shown in the figure: 1 compressor, 2 outdoor heat converters, 3 indoor heat converters, 4 throttling arrangements, 5 four-way electromagnetic reversing valves, 6; 7 gas-liquid separators, 8; 9 check valves, 10 distributors.
The specific embodiment
The present invention places the gas-liquid separator 6 at throttling arrangement 4 two ends respectively mainly by compressor 1, outdoor heat converter 2, indoor heat converter 3, throttling arrangement 4, four-way electromagnetic reversing valve 5; 7, place gas-liquid separator 6; Check valve 8 on the 7 gaseous refrigerant outlet connecting pipes; 9 and composition such as tube connector, throttling arrangement 4 two ends respectively with gas-liquid separator 6; 7 import is connected, gas-liquid separator 6; 7 liquid refrigerant outlet is connected gas-liquid separator 6 with an end of outdoor heat converter 2, indoor heat converter 3 respectively; 7 gaseous refrigerants outlets respectively with the other end of outdoor heat converter 2 and indoor heat converter 3 by check valve 8; 9 are connected.
During refrigeration, compressed machine 1 is collapsed into the gaseous refrigerant of HTHP, become high pressure liquid refrigerant by four-way electromagnetic reversing valve 5 through outdoor heat converter 2 condensations, the high pressure liquid refrigerant gas-liquid separator 6 of flowing through enters throttling arrangement 4 throttlings becoming low-temp low-pressure gas, the liquid mix refrigerant, separate through gas-liquid separator 7, isolated gaseous refrigerant is got back to compressor 1 by check valve 9 through four-way electromagnetic reversing valve 5, liquid refrigerant (through distributor 10) enters indoor heat converter 3 heat absorption evaporations becomes gaseous refrigerant, gaseous refrigerant and the gaseous refrigerant of separating from gas-liquid separator 7 are got back to compressor 1 through four-way electromagnetic reversing valve 5 together, finish kind of refrigeration cycle.At this moment, check valve 8 is imported and exported under the differential pressure action of two ends at outdoor heat converter 2 and is in closed condition.
When heating, compressed machine 1 is collapsed into the gaseous refrigerant of HTHP, become high pressure liquid refrigerant by four-way electromagnetic reversing valve 5 through indoor heat converter 3 condensations, the high pressure liquid refrigerant gas-liquid separator 7 of flowing through enters throttling arrangement 4 throttlings becoming low-temp low-pressure gas, the liquid mix refrigerant, separate through gas-liquid separator 6, isolated gaseous refrigerant is got back to compressor 1 by check valve 8 through four-way electromagnetic reversing valve 5, the 2 heat absorption evaporations of liquid refrigerant inlet chamber outer heat-exchanger become gaseous refrigerant, gaseous refrigerant and the gaseous refrigerant of separating from gas-liquid separator 6 are got back to compressor 1 through four-way electromagnetic reversing valve 5 together, finish heating circulation.At this moment, check valve 9 is imported and exported under the differential pressure action of two ends at indoor heat converter 3 and is in closed condition.
