Description
Technical field
The present invention relates to a kind of air interchanger.
Background technology
Generally, along with the prolongation of time, the content of carbon dioxide raises the air of enclosure space because of the respiration of life entity.Carbon dioxide content can make the breathing of life entity feel very ill when increasing, so often use air interchanger at the many narrow spaces of people such as office or vehicle, the air of indoor pollution is changed into outdoor ozone.This air interchanger has forces the pressure fan that blows to room air and outdoor air, by pressure fan the room air that pollutes is discharged to be drawn into fresh outdoor air indoor again outdoor the time.But when indoor refrigeration and ventilation are carried out simultaneously, along with the room air of refrigeration is discharged, the outer hot-air of suction chamber simultaneously, and the temperature of outdoor air is than cryogenic temperature height, so the refrigerating efficiency reduction.When indoor heating carries out simultaneously with ventilation, along with a room air that heats is discharged, the outer cold air of while suction chamber, and the temperature of outdoor air ratio heats the temperature sinking, and heating efficiency reduces.
As shown in Figure 1, 2, above-mentioned air interchanger also is provided with and makes the heat exchanger that produces heat exchange between room air and the outdoor air.
Login discloses the flat 09-137984 of communique number existing air interchanger at Japan Patent, forms the outdoor air inlet hole (4a) of suction chamber outer air and the room air tap (6b) of discharge room air in a side of rectangular container (2); The another side of shell (2) forms outdoor air tap (4b) of discharging outdoor air and the room air inlet hole (6a) that sucks room air; The central authorities of shell (2) are provided with heat exchanger (8), are formed with the stream of outdoor air and indoor air flows in the described heat exchanger (8); The both sides central authorities of shell (2) are respectively arranged with the drawing fan (10) and the scavenger fan (20) of discharging room air of suction chamber outer air.In addition, shell (2) is inner also be provided with the space obstacle portion that forms air duct (7a, 7b) with the air channel (9a, 9b, duct).(7a 7b) guides to the outdoor air that sucks from outdoor air inlet hole (4a) heat exchanger (8) or a room air that sucks from room air inlet hole (6a) is guided to heat exchanger (8) in above-mentioned space obstacle portion; (9a 9b) is expelled to the outdoor air by heat exchanger (8) outdoor air tap (4b) or the room air by heat exchanger (8) is expelled to room air tap (6b) in above-mentioned air channel.Above-mentioned heat exchanger (8) is arranged in the shell (2) by the inspection socket (2a) that is formed on the central side of shell (2) is dismountable.And make the corner part of heat exchanger (8) slidably insert the space obstacle portion that is respectively formed at that is arranged on (7a, 7b) two ends and air channel (9a, 9b) track of above and below (5, rail) on.In order to improve heat exchanger effectiveness, also can alongst be arranged in parallel a plurality of heat exchangers (8).Above-mentioned drawing fan (10) and scavenger fan (20) are separately positioned on and connect air channel (9a, 9b) fan installing rack (12 is set, 22) inboard, and drawing fan (10) and scavenger fan (20) all adopt the Sirocco fan (sirocco fan) of discharging along circumferencial direction again behind direction of principal axis suction chamber outer air or the room air.The motor (14,24) that drives drawing fan (10) and scavenger fan (20) respectively is fixedly installed on separately the fan installing rack (12,22).And driving the motor (14) of drawing fan (10) and the motor (24) of driving scavenger fan (20) is provided with towards the both sides of heat exchanger (8) central authorities.
But in existing air interchanger in order to improve heat exchanger effectiveness, cross shell and connect 2 above heat exchangers are set, though design can improve heat exchanger effectiveness like this, but length lengthening along with heat exchanger, the size of shell is also big along with change, thereby the volume of entire product has also become greatly.
