Description
Technical field
The present invention relates to conditioning unit field, particularly a kind of railway air conditioner system.
Background technology
Railway air conditioner system, due to the particularity of its condition, higher requirement is had to a/c system, especially bullet train, therefore, for the corresponding air conditioner system of operation service conditions Development and design of bullet train reality, must adapt to and meet new, the higher requirement of high-speed railway passenger to a/c system.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of railway air conditioner system, improves air-conditioner efficiency and Energy Efficiency Ratio.
A kind of railway air conditioner system that the embodiment of the present invention provides, comprise the compressor, condenser, expansion valve, the evaporator that are in turn connected to form closed cycle system, between described compressor and condenser, be provided with exchanger, described exchanger is also communicated with described evaporator.
Alternatively, described evaporator is provided with chassis, and described chassis is communicated with described exchanger.
Therefore application the present embodiment technical scheme, due to the high temperature refrigerant adopting evaporator condensation water cooling compressor to discharge, obtain very fast cooling refrigeration agent, improve more than 20% compared to conventional track a/c system heat exchange property, improving energy efficiency ratio, improves air-conditioner efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of railway air conditioner system diagram provided by the invention;
Fig. 2 is a kind of heat exchanging process figure provided by the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment:
General a/c system primarily of compressor, condenser, expansion valve and evaporator four parts composition, and is connected to form a closed circulating system with pipeline.Its working process is as follows: refrigerant liquid absorbs the heat of cooled object and sucked by compressor after being gasificated into the steam of low-pressure low-temperature in evaporator.Refrigerant vapor compression is become the higher steam of pressure, temperature and enters condenser by the certain power of compressor consumption.The refrigerant vapour of high pressure, high temperature is by ambient air (or water) cooling in condenser, and refrigeration working medium is released heat and is condensed into liquid.Because the temperature of refrigerant liquid is also higher than ambient medium temperature, the temperature feeding evaporator that must fall within the range of lower than cooled object could produce refrigeration.For this reason, first allow the liquid refrigerant of high pressure, high temperature through expansion valve reducing pressure by regulating flow, simultaneous temperature also reduces, and then enters evaporator.In evaporator, the refrigerant of low pressure, low temperature absorbs again the heat of cooled object, flashes to the refrigerant vapour of low pressure, low temperature, then is sucked by compressor, circulate so again and again.Like this, refrigerant will experience four thermodynamic processs such as compression, condensation, throttling and evaporation and just completes a refrigerating cycle in the refrigeration system closed.In the circulating cycle, compressor will consume certain merit, cryogenic object liberated heat could be transferred in the ambient medium of high temperature and go, to reach the object of refrigeration.
The present embodiment provides a kind of railway air conditioner system, as shown in Figure 1, comprise the compressor 10, exchanger 50, condenser 20, expansion valve 30, the evaporator 40 that are in turn connected to form closed cycle system, be also communicated with described evaporator 40 with the exchanger 50 between condenser 20 at described compressor 10.
During work, evaporator 40 temperature of described railway air conditioner system is lower, catch a cold during for periods of heating 40, condensate moisture in air becomes water, be subject to Action of Gravity Field, run down into evaporator 40 chassis, its coolant-temperature gage is lower, and as shown in Figure 2, described cool solidifying water is flowed in described exchanger 50 by the chassis of described evaporator 40.And the high temperature refrigerant of discharging is compressed from described compressor 10, be compressed, absorb heat, temperature is higher, also flows in exchanger 50, the condensed water heat-shift flowed into evaporator 40, reach lower temperature quickly, after completing thermal exchange, described refrigerant flows into described condenser 20 by described exchanger 50, and described condensed water is flowed out in described evaporator 40 by described exchanger 50.
Visible, the high temperature refrigerant adopting evaporator condensation water cooling compressor to discharge, obtains very fast cooling refrigeration agent, and improve more than 20% compared to conventional track a/c system heat exchange property, improving energy efficiency ratio, improves air-conditioner efficiency.
Above-described embodiment, does not form the restriction to this technical scheme protection domain.The amendment done within any spirit at above-mentioned embodiment and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in this technical scheme.
Claims (2)
1. a railway air conditioner system, comprise the compressor, condenser, expansion valve, the evaporator that are in turn connected to form closed cycle system, it is characterized in that, between described compressor and condenser, be provided with exchanger, described exchanger is also communicated with described evaporator.
