Vehicle air conditioning plant

摘要

The air conditioning plant has a control system for the external air brought into the air conditioner casing (2) when the outer air temperature is lower than that inside. It has a control system for internal air recycled through it when the outer air temperature is higher than that inside, when the passenger wants to lower the temperature inside the vehicle. When the passenger wants to raise the temperature inside the vehicle, this principle is reversed. The casing has inner air inflow apertures (5a,5b), an outer air inflow apertures (5c) and two through air passages (18,19).
