Abstract
The utility model relates to a fresh air ventilating system for a double-deck coach, which comprises a principal air conditioner, and an upper air duct and a lower air duct which are communicated with the principal air conditioner, wherein an evaporator is arranged in the principal air conditioner, a blower fan is arranged in the evaporator, at least an air inlet door is arranged at the tail part of the coach, the air inlet door is communicated with the evaporator, and the evaporator is communicated with the atmosphere outside through the air inlet door; at least an air outlet door is arranged at the front part of the coach, and the inside of the coach is communicated with the atmosphere outside through the air outlet door. The utility model can effectively form the inside and outside air circulation, filter and pre-cool the hot air sucked from outside and improve the comfortableness of the passenger.
Description
Technical field
The utility model relates to the rear-mounted air conditioning for automobiles in a kind of inside, is specifically related to a kind of ventilation air interchange system of double deck passenger car air-conditioning.
Background technology
Double deck passenger car generally adopts inner rear-mounted air conditioning for automobiles, cold air through the A/C evaporator refrigeration is sent in the car by force by the exhaust passage of levels in the car, air-conditioning duct through levels car inner top both sides is sent into levels in the car respectively, reach refrigeration, heat-exchanged air is got back to evaporator through the air return duct in the car again, forms refrigerating cycle with this.So not only do not have the fresh-air ventilation function, rational and effective is distributed the air output of levels as required.Form the inner air and outer air circulation even the compartment has ventilation inlet (as the skylight) also to be difficult for actv., cause oxygen content decline in the compartment, the passenger is uncomfortable.When the old and the weak, sick passenger were especially arranged among the passenger, the fresh-air ventilation function just seemed particularly important fast and effectively.
The utility model content
The utility model has been designed and developed out a kind of inner air and outer air that can effectively form and has been circulated, can filter the hot air that sucks from the external world double deck passenger car ventilation air interchange system of precooling, raising passenger comfort at the deficiencies in the prior art.
The utility model is achieved through the following technical solutions:
A kind of double deck passenger car ventilation air interchange system, include air-conditioner host, with air channel, upper strata that is connected with air-conditioner host and lower floor air channel, be provided with evaporator in the air-conditioner host, be provided with blower fan in the evaporator, the afterbody of passenger vehicle offers at least one inlet air door, and inlet air door communicates with evaporator, and evaporator communicates with ambient atmosphere by inlet air door; Offer at least one air-out air door in the passenger vehicle front portion, communicate with ambient atmosphere by the air-out air door in the car.
A kind of double deck passenger car ventilation air interchange system, the ventilation inlet place in air channel, upper strata and lower floor air channel is equipped with a plurality of blower fans.
A kind of double deck passenger car ventilation air interchange system, described inlet air door is connected with evaporator by a wind channel.
A kind of double deck passenger car ventilation air interchange system, described inlet air door all is connected an automatically controlled air door switch in order to control opening and closing air door with the air-out air door.
The utility model is provided with " car in air circulation system ", inlet air door, wind channel, exhaust damper, makes that Che Nei and car are outer to be realized communicating or isolated by artificial control, can come arbitrarily to realize at any time that the car inner air and outer air exchanges according to actual conditions in the car.When needing to renew wind in the car, the driver opens air door switch and makes air intake, the air-out air door is opened simultaneously, form the path of inner air and outer air exchange, principle according to " vehicle in motion; the outer rear portion of car is a zone of positive pressure; the outer front portion of car is a zone of negative pressure ", the fresh air at the outer rear portion of car is pressed into inlet air door, fresh air is introduced " lower floor's air return duct " by new wind wind channel, enter the A/C evaporator precooling then, pass through the evaporation fan of A/C evaporator again according to certain air quantity ratio, be pressed into the levels compartment respectively, make the levels compartment all can obtain enough amount of fresh air, simultaneously original hypoxic air in the car, be forced out outside the car by exhaust damper, thereby realize the fresh-air ventilation in whole compartment.When the oxygen content in the compartment was enough, the driver can close air door switch, and then inlet air door and exhaust damper are closed simultaneously, made car inside and outside isolated, and fresh-air ventilation finishes.With this, can random at any time unlimited fresh-air ventilation.
Description of drawings
Accompanying drawing is a double deck passenger car air conditioner fresh air air exchange system structural representation.
The specific embodiment
Shown in accompanying drawing.
The utility model includes air-conditioner host 1, with air channel, upper strata 4 that is connected with air-conditioner host 1 and lower floor air channel 6, be provided with evaporator 2 in the air-conditioner host 1, be provided with blower fan 3 in the evaporator 2, afterbody at passenger vehicle offers an inlet air door 7, inlet air door 7 is connected with evaporator 2 by a wind channel 8, and evaporator 2 communicates with ambient atmosphere by wind channel 8 and inlet air door 7; Offer an air-out air door 5 in the passenger vehicle front portion, communicate with ambient atmosphere by air-out air door 5 in the car.The ventilation inlet place in air channel, upper strata 4 and lower floor air channel 6 is equipped with a plurality of blower fans 3.Inlet air door 7 all is connected an automatically controlled air door switch in order to control opening and closing air door with air-out air door 5.
The utility model is provided with " car in air circulation system ", inlet air door 7, wind channel 8, air-out air door 5, makes that Che Nei and car are outer to be realized communicating or isolated by artificial control, can come arbitrarily to realize at any time that the car inner air and outer air exchanges according to actual conditions in the car.When needing to renew wind in the car, the driver opens automatically controlled air door switch and makes inlet air door 7, air-out air door 5 is opened simultaneously, form the path of inner air and outer air exchange, principle according to " vehicle in motion; the outer rear portion of car is a zone of positive pressure; the outer front portion of car is a zone of negative pressure ", the fresh air at the outer rear portion of car is pressed into inlet air door 7, by wind channel 8 fresh air is introduced the A/C evaporator precooling, pass through the evaporation fan 3 of A/C evaporator again according to certain air quantity ratio, be pressed into the levels compartment by air channel, upper strata 4 and lower floor air channel 6 respectively, make the levels compartment all can obtain enough amount of fresh air, original hypoxic air in the car is forced out outside the car by air-out air door 5 simultaneously, thereby realizes the fresh-air ventilation in whole compartment.When the oxygen content in the compartment was enough, the driver can close automatically controlled air door switch, then advanced inlet air door 7, air-out air door 5 is closed simultaneously, made car inside and outside isolated, and fresh-air ventilation finishes.With this, can random at any time unlimited fresh-air ventilation.
