Abstract
The invention relates to a train air-conditioner equipped with a novel air supply heater, comprising an evaporator, a compressor, a stop valve, and a condenser, wherein the evaporator is installed on the air supply pathway of the train air-conditioner, the heater is also installed on the air supply pathway of the train air-conditioner, and a three-way valve is arranged between the stop valve and the condenser. The three-way valve enables high temperature air from the condenser to flow in two directions at different times: one is delivering to the condenser directly, and the other is first transmitting to the heater and then delivering to the condenser. By adopting the train air-conditioner provided by the invention, the air supply temperature can be raised through starting the heater when the temperature is low in a railway carriage.
Description
Technical field
The present invention relates to a kind of a/c system, the track air-conditioning of the novel air-supply temperature booster of particularly a kind of track traffic band.
Background technology
Existing rail traffic vehicles all adopts the cold-warm type monobloc of single cold type or charged heating with subway air conditioner group.
The wind pushing temperature of single cold type unit air-conditioning unit can only change according to the variation of temperature in the compartment and outdoor temperature; If the temperature in the compartment is low excessively; The wind pushing temperature of air-conditioning unit will be very low, and the wind-warm syndrome of seeing off from the vehicle supply grille will be lower, because the railcar air-supply all is the top air-supply; So just make the head and the shoulder that arrive the people than the wind of lower temperature, make the people produce uncomfortable feeling; If the humidity of vehicle is excessive simultaneously, also can make wind pushing temperature very low, produce above-mentioned same problem.
The cold-warm type unit air-conditioning unit of charged heating generally all is to supply the heating in winter to use; If this temperature booster is used for when refrigeration compensation during over-cooled compartment temperature; Because electro heat will consume a large amount of electric energy; So the power consumption of this unit will be very big, do not meet the existing requirements of saving energy that air conditioner of subway vehicle is proposed.
Therefore, there is following problem in existing track air-conditioning with novel air-supply temperature booster:
When 1, the very big or indoor and outdoor temperature of humidity was low in the compartment, wind pushing temperature that can not actv. control air-conditioning made the passenger produce uncomfortable feeling easily.
2, utilize the electro heat heating, can improve the wind pushing temperature of air-conditioning, but increase the power consumption of air-conditioning unit, increased the energy consumption of air-conditioning.
3, the electro heat process makes the airflow field and the temperature field acute variation in compartment, out of reach homogeneity.
Summary of the invention
To the objective of the invention is in order solving the problems of the technologies described above, a kind of track air-conditioning with novel air-supply temperature booster to be provided, in the hope of realizing through the over-cooled compartment temperature of compensation under the structure of original air-conditioning.
The technical scheme that the present invention takes is:
A kind of track air-conditioning with novel air-supply temperature booster; Comprise evaporator, compressor, shutoff valve and condenser; Said evaporator is installed on the air-out path of track air-conditioning, it is characterized in that, on the air-out path of track air-conditioning, temperature booster is installed also; A triple valve is set between said shutoff valve and condenser, and said triple valve makes high-temperature gas that compressor comes produce two flow direction: a, directly deliver to said condenser in different time; B, deliver to said condenser again after being sent to said temperature booster.
Further, said temperature booster and said evaporator bank lump together.
Further, according to the air-conditioning air-out direction temperature booster is installed in the place ahead of evaporator.
Further, said triple valve is a three-way magnetic valve, and Temperature Humidity Sensor is set in subway carriage, the said opening direction that passes through humiture situation automatic guidance three-way magnetic valve in the compartment with the track air-conditioning of novel air-supply temperature booster.
The invention has the beneficial effects as follows:
1, for the air-conditioning of single cold type, only increase a fraction of temperature booster and a three-way magnetic valve, but can well guarantee wind pushing temperature, improved passenger's traveling comfort greatly;
2, for the air-conditioning of cold-warm type, after having increased a fraction of temperature booster and three-way magnetic valve, can save an electro heat, manufacturing cost can save 1/3;
3, for the air-conditioning of cold-warm type, it has saved electrically heated consumption of current, has reduced the power consumption of air-conditioning, so annual MTR can save a part of electric weight on the use cost;
4, improve wind pushing temperature, improved the temperature field of vehicle interior, improved passenger's environment by bus;
5, through utilizing the exhaust gas heat of compressor, save original consumption of current, reached purpose of energy saving.
Description of drawings
Accompanying drawing 1 is a schematic diagram of the present invention.
Label in the accompanying drawing is respectively:
1. temperature booster; 2. evaporator;
3. heating power expansion valve; 4. electromagnetic valve;
5. device for drying and filtering liquid-sighting glass; 6. condenser;
7. three-way magnetic valve; 8. shutoff valve;
9. compressor; 10. shutoff valve;
11. gas-liquid separator.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to a kind of track air-conditioning with novel air-supply temperature booster of the present invention.
Referring to accompanying drawing 1; The loop of this a/c system comprises compressor 9, evaporator 2, condenser 6, electromagnetic valve 4 and heating power expansion valve 3; Through shutoff valve 8 refrigerant is delivered to condenser 6 at compressor 9; A triple valve 7 is installed between shutoff valve 8 and condenser 6, temperature booster 1 is installed through triple valve 7.Realize that through control triple valve 7 switches the exhaust of compressor 9 directly gets into condenser 6 and still gets into condenser 6 again through temperature booster 1 earlier.
Continuation is referring to accompanying drawing 1; During normal refrigeration, after the refrigerant that from evaporator 2, comes out has absorbed the heat in the compartment, be compressed through gas-liquid separator 11 and compress after machine 9 sucks; Compression back through shutoff valve 8 and triple valve 7 get into condensers 6 and be condensed into the liquid of high pressure low temperature after; Through behind device for drying and filtering liquid-sighting glass 5 and the electromagnetic valve 4, carry out absorbing heat at entering evaporator 2 after the throttling again, thereby accomplish a whole circulation through heating power expansion valve 3.
Continuation is referring to accompanying drawing 1; When wind pushing temperature is very low; After the refrigerant that from evaporator 2, comes out has absorbed the heat in the compartment, be compressed through gas-liquid separator 11 and compress after machine 9 sucks, after the compression back gets into temperature boosters 1 preheating air-supply through shutoff valve 8 and triple valve 7; After being condensed into the liquid of high pressure low temperature through check valve 10 entering condensers 6 again; Through behind device for drying and filtering liquid-sighting glass 5 and the electromagnetic valve 4, carry out absorbing heat at entering evaporator 2 after the throttling again, thereby accomplish a whole circulation through heating power expansion valve 3.Because the gas temperature after compressor 9 compressions is spent up to seventy or eighty, can make temperature booster 1 reach the purpose of heating fully, and make full use of the energy of a/c system.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
