本发明为客车双风道空调装置。该空调装置系由通风器、空调机组、通往包间的冷、热风道以及包间内的手动空气混合装置组成。通风器可有选择地吸入再循环空气或新鲜空气。空调机组的空气加热器和冷却器采用前后布置方式,其两侧为旁通风道。双风道中的一个风道送热风,另一个风道送冷风。空调机组和双风道间设有冷、热风导向装置。通过该装置中相应的风门调节系统或其它类似的结构,使双风道根据需要分别与空气加热器或冷却器以及旁通风道等连通。这样,当采暖与制冷工况相互转换时,可用自动或手动的调节装置,而不必改变其调节方向。本发明有以下两个结构方案:图1～3为一个方案;图5～7为另一个方案。
The invention is a double-air-way air conditioner for a passenger car. The air-conditioning unit consists of ventilators, air-conditioning units, to the private cold room, hot air duct and the private room in the manual air mixing device composition. The ventilator selectively inhales recirculation air or fresh air. Air-conditioning unit air heater and cooler front and rear layout, both sides of the bypass duct. One of the double air duct to send hot air, the other air duct to send cold air. Air-conditioning units and dual air duct with cold and hot air guide. Through the corresponding damper adjusting system or other similar structure in the device, the dual air ducts are respectively connected with the air heater or cooler, the bypass air duct and the like as needed. In this way, when the heating and cooling conditions change each other, automatic or manual adjustment device can be used without having to change its adjustment direction. The present invention has the following two structural schemes: Figures 1 to 3 are one scheme; and Figures 5 to 7 are another scheme.
