BBC公司为客车空调设计了一种双风道空调装置。它装于车辆地板底下的机组内,分冷热两条风道输入包间。包间内的温度可在一定的限度内由旅客按需要调节。空气混合装置中的气流须按一定的比例混合,所吹出的新鲜空气量与所诱导的包间空气量大致相等。风道与空气混合装置的结构如下: 一般结构新鲜空气通过沿车辆侧墙布置的风栅吸入并经风道输入空气处理装置。在该装置中,新鲜空气经空气过滤器后,流入起冷却作用的热交换器进行必要的去湿,然后再进入第二个热交换器
BBC designed a double air-conditioned air conditioner for passenger car air conditioning. It is installed in the unit under the floor of the vehicle, hot and cold air channels into the private rooms. Room temperature can be within a certain limit by the passengers as needed adjustment. The air mix in the air mixing unit must be mixed at a rate that will give approximately the same amount of fresh air as the induced air in the compartment. The structure of the air duct and air mixing device is as follows: General structure Fresh air is sucked into the air handling unit through the air duct arranged along the side wall of the vehicle and through the air duct. In the device, fresh air passes through the air filter, flows into the cooling heat exchanger for the necessary dehumidification, and then into the second heat exchanger
