Aeration device.
Background technique
Urban public transport vehicle accounts for the ratio of city automobile ownership less than 10%, but the total distance travelled of Zhan is close
50%, to the specific gravity of urban atmospheric pollution up to 40% or more.In recent years to solve the problems, such as that urban public transport is seriously polluted,
Bus using natural gas is quickly grown.It is discharged from automobile exhaust pollutant, compared with gasoline/diesel vehicle, LNG automobile CO discharge can
85% or more is reduced, CO 2, which can reduce 23% or so, NO x, can reduce 80% or so.Since to do fuel environment protecting obvious by LNG,
Currently, many cities in the whole nation start using bus using natural gas.On the other hand existing bus air conditioner system uses refrigeration mode
In cooler that sucking air is cooling by arranging that air port is blown into car everywhere in the car for freon, air port send a point temperature to exist
16 degree or so, mainly based on the temperature of adjusting in-vehicle air, humidity is less paid close attention to.And air quality in vehicle is poor, is
Its cooling coil undertakes two functions of dehumidifying and cooling, and coil surface constantly has condensed water generation, and surface long term is in wet cooling condition,
It is easy to mould growth under summer temperature condition, in addition car belongs to public place, dust bacterium etc. is easily entrained and causes sky
Gas poor quality.
Notification number CN102582397A provides a kind of utilization device for liquified natural gas bus cold energy, which sets
The pipe type heat exchanger with blower is set, LNG enters pipe type heat exchanger by pressure regulator valve, and suction-type wind is installed in heat exchanger one end
Fan, is bus cooling supply with the cold air of low temperature.But the cold energy that this technology heats up with only LNG gasification, it reduces
Existing air-conditioning system load reduces the energy waste of bus public affairs tune, but there is no improvement public transport air quality in vehicle, and
Air temperature is too low to have made one cold wind feeling, can make one to feel under the weather.Need to adjust thus interior temperature control system and
The regulating system of vehicle humidity, interior temperature control system can continue to use freon compression refrigerating system, but refrigeration system
Evaporating temperature is higher than existing evaporating temperature；Refrigeration system energy consumption is thus lower.There is an urgent need to provide the humidity tune of fresh air at present
Section system, the present invention are exactly the humidity regulation aeration device for adapting to this requirement and designing.
Summary of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of novel LNG bus temperature and humidity Independent air conditioning fresh air
Device, system engine exhaust heat dehumidification regeneration system solution, with LNG heating gasification cooling capacity to dehumidifying fresh air cooling, with removing
Vehicle humidity is adjusted in fresh air after wet cooling, makes one no creeping chill, improves current bus air quality in vehicle, simultaneously
Cooperation cooling refrigeration system effectiveness is also improved.
The specific technical solution of the present invention is as follows:
A kind of novel LNG bus temperature and humidity Independent air conditioning aeration device, including LNG tank, heat regenerator, heat exchanger,
Regenerator, dehumidifier and aerial cooler, it is characterised in that: the LNG tank, cold energy regenerator, heat regenerator and engine it
Between be sequentially connected with supply air line, in which: pressure regulator valve is installed on the pipeline between LNG tank and cold energy regenerator；It is described to start

The cold energy regenerator and heat exchanger form closed circulation line two by eg pump；The heat exchanger and sky
Closed circulation line three is formed by water pump A between Gas Cooler；Between dehumidifier, aerial cooler and fresh-air fan sequentially
Connection forms air supply pipeline.
Preferentially, it is sequentially connected with to form inlet pipe between the dehumidifier, heat regenerator, thermal storage device and regenerator,
In: solution pump A is installed on the pipeline between thermal storage device and regenerator；It is suitable between the regenerator, heat regenerator and dehumidifier
Secondary connection forms outlet tube road, in which: is equipped with solution pump B between heat regenerator and dehumidifier on pipeline.
Beneficial effects of the present invention: system engine exhaust heat dehumidification regeneration system solution, with LNG heating gasification cooling capacity
To dehumidifying fresh air cooling, vehicle humidity is adjusted with fresh air after dehumidifying and cooling, makes one no creeping chill, improves current public transport
Vehicle air quality in vehicle, while cooling refrigeration system effectiveness being cooperated also to be improved.
Detailed description of the invention
Fig. 1 is the structural plan of the novel LNG bus temperature and humidity Independent air conditioning aeration device of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
As shown, a kind of novel LNG bus temperature and humidity Independent air conditioning aeration device, including LNG tank 3, recuperation of heat
Device 12, heat exchanger 5 and dehumidifier 15 sequentially connect between the LNG tank 3, cold energy regenerator 9, heat regenerator 12 and engine 16
It is connected to supply air line, in which: pressure regulator valve 7 is installed on the pipeline between LNG tank 3 and cold energy regenerator 9；The engine 16 with
Closed circulation line one is formed by water pump B between thermal storage device 1；
The cold energy regenerator 9 and heat exchanger 5 pass through eg pump 4 and form closed circulation line two；The heat exchanger 5
Closed circulation line three is formed by water pump A between aerial cooler 14；Dehumidifier 15, aerial cooler 14 and fresh air wind
It is sequentially connected with to form air supply pipeline between machine 13.
It is sequentially connected with to form inlet pipe between dehumidifier 15, heat regenerator 12, thermal storage device 1 and regenerator 11, in which: storage
Solution pump A is installed on pipeline between hot device 1 and regenerator 11；The regenerator 11, heat regenerator 12 and dehumidifier 15 it
