The invention relates to the field of vehicle centralized air conditioners, in particular to an independent circulation air conditioning system and method.The independent circulation air conditioning system comprises a vehicle body, an air conditioning unit and a heat exchange unit, a plurality of carriages are formed in the vehicle body, a main air duct is further formed in the vehicle body, and the main air duct is divided into a dynamic pressure cavity, a static pressure cavity and an air return cavity; each compartment is at least correspondingly connected with one heat exchange unit, and the heat exchange units are located in the static pressure cavities and communicate with the dynamic pressure cavities and the air return cavities correspondingly. Heat exchange airflow output by the air conditioner enters the static pressure cavity through the dynamic pressure cavity, and is conveyed back into the air conditioner from the air return cavity after being subjected to heat exchange through the heat exchange unit. Internal air flow in the compartment enters the air flow channel of the heat exchange unit, exchanges heat with the heat exchange air flow in the air flow channel, and then is conveyed back into the compartment from the air outlet end; the air in each compartment is independently subjected to heat exchange circulation with the air flow fed into the main air duct by the air conditioning unit through the heat exchange unit, so that the transmission of viruses and bacteria between the compartments is reduced, and the safety is higher.

    本发明涉及车辆集中空调领域,具体而言,涉及一种独立循环空调系统及方法,独立循环空调系统包括车体、空调机组及换热单元,车体内形成有多个车厢,车体内还形成有主风道,主风道分为动压腔、静压腔以及回风腔;各车厢至少对应连接有一个换热单元,换热单元位于静压腔内且分别与动压腔和回风腔连通;空调器输出的换热气流经动压腔进入到静压腔内,经过换热单元换热后,从回风腔输回至空调器内;车厢内的内部气流进入到换热单元的气流通道内,在气流通道内与换热气流换热后,从出风端输回至车厢内;各个车厢内的气体通过换热单元单独与空调机组送进主风道的气流进行换热循环,有利于减小车厢之间病毒和细菌的传播,安全性更高。
