Abstract
The utility model relates to an air refrigerating and heating device for electric locomotives, which is provided with an oil-water separator. The rear part of the oil-water separator is connected with the oil-water separator whose rear part is connected with a turbine expander and the rear part of the turbine expander is connected to the cab of the electric locomotive through a hand-operated three-way valve. The device is suitable for the characteristics of the electric locomotives and utilizes the compressed air of the air braking system of the electric locomotive as air source to provide fresh air for the cab of the electric locomotive and the air curtain of the window. Therefore, when the electric locomotive runs 30 kilometers, the frequent power failure of an air conditioner owing to once sudden power failure of excess phase can be removed.
Description
The utility model relates to a kind of electric locomotive air cooling, heating system.
In the prior art, at present the electric locomotive air-conditioning is by two single-phase 220V, and power is that parts such as R12 air-conditioning compressor, the two cover condensers of 1.3KW, fan, two cover evaporators, blower fan and 6KW electric heater are formed.Every motor rated current of air-conditioning compressor is 7A, and when starting electric current up to 50A.The supply line of electric locomotive power supply is a sectional power supply, about 30 kilometers of every section interval, therefore, electric locomotive with 90 kilometers of present moving velocitys/time, 30 kilometers (the about 20 minutes) back that will cut off the power supply of then whenever travelling is changed another interval circuit section and is powered, this is with regard to appellation " cross phase-splitting " outage, about this time in about 5 seconds that cross the phase-splitting outage, and electric locomotive that Here it is the characteristics of taking second place of must cutting off the power supply about 20 minutes of whenever travelling.The R12 A/C also is to use the electric locomotive power supply; so its inevitable with the mistake phase-splitting of electric locomotive sudden power correspondingly; when restoring electricity again after the general dichlorodifluromethane A/C in running condition sudden power; because the refrigeration system high-low pressure is lack of equilibrium still; make the compressor can't normal starting; at this moment very easily damage compressor; just can restart so will wait for 3-5 minute after the A/C sudden power; though increased bypass disc between the height pressure pipe at present; floor time can be shortened to about 1 minute; but electric locomotive whenever travels and wanted phase-splitting sudden power phenomenon about 20 minutes and still can't change the influence of R12 A/C operation intermediate frequency ground outage.This is not only very big to the influence in service life of R12 compressor, especially rated current respectively is 7A during the normal two compressor parallel operations of A/C, start at every turn that then electric current will be up to 100A, by present electric locomotive travel 90 kilometers/time, per hour will start 3 times, even shortened to 1 minute/time by the time of restarting after the sudden power, this will increase 1.5KW to every electric locomotive power consumption hourly, every annual work-hours of electric locomotive was by 4800 hours, and this will make the annual additive decrementation electric energy of every electric locomotive 7200KW/.If the capable running speed degree of electric locomotive from now on improves, the power consumption of this part will be bigger.Therefore, from the capable fortune characteristics of electric locomotive, the R12 A/C can only be a stopgap, in case the electric locomotive moving velocity bring up to 150 kilometers/time, cross in per hour phase-splitting outage number of times will be increased to 5 times/time, this R12 A/C can also be accomplished normal refrigeration
The purpose of this utility model is: provide a kind of and can adapt to the capable fortune of electric locomotive characteristics, influenced by phase-splitting outage down, and can drive the department chamber to electric locomotive continuously and drive and take charge of the interior environment system that chamber window air curtain provides fresh air cool in summer and warm in winter.
The technical solution of the utility model is: a kind of electric locomotive characteristics that are applicable to, with the pressurized air is the interior environment system of source of the gas, this device utilizes the pressurized air of electric locomotive Pneumatic brake systems to be source of the gas, device is provided with oil water separator, be connected with filter behind the oil water separator, the admission port that is connecting turbo-expander behind the filter, pure pressurized air enters turbo-expander and expands rapidly under adiabatic condition, the enthalpy of air and temperature sharply descend thereupon, low pressure after the adiabatic expansion, Cryogenic air is passed through a manual three-way valve through the exhausr port of turbo-expander, can make low pressure when summer, Cryogenic air is connected to electric locomotive and drives the department chamber and drive department's chamber window air curtain; Can make in the time of in the winter time this part low pressure, Cryogenic air through manual triple valve be converted to direct discharge drive the department chamber or receive the easy heating position of electric locomotive make cooling system conditioner and use after emptying.The coaxial blower fan sucking hole of the turbo-expander of this device is connected in driving of electric locomotive and takes charge of the chamber, and the exhaust outlet of this blower fan connects a manual three-way valve, can drive the department chamber with driving the indoor vitiated air discharge of department in summer; Hot air after the blower fan heating can be sent in the winter time and drive the department chamber and drive department's chamber window air curtain heating.
The advantage of the utility model is:
1. directly electricity consumption of the utility model only is source of the gas with the pressurized air, so be subjected to electric locomotive to cross influencing of phase-splitting sudden power down, can drive to take charge of the chamber and drive to electric locomotive and take charge of chamber window air curtain refrigerant comfortable fresh air is provided incessantly;
2. the utility model does not use the refrigerant of forbidding in the world, suffers from after atmosphere, environment are had no pollution;
3. both cooling rate was fast for the utility model, can regulate arbitrarily again and drive department's chamber required temperature, but and can freeze summer, heat supply again in winter;
4. the utility model is simple in structure, does not have complicated electrical control equipment, and maintaining is very convenient;
5. the utility model volume and weight only are 1/10 of R12 A/C, and equipment investment can reduce greatly;
6. 40% of the annual power consumption expense of the not enough R12 A/C of the cost of the utility model year consumption pressurized air.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing is a structural representation of the present utility model:
Wherein: 1. oil water separator 2. filters 3. turbo-expanders and coaxial blower fan
4. manual three-way valve 5. is driven department chamber 6. and is driven department's chamber window air curtain
