1. The air which cools (or heats) the cab is taken in
from outside (or inside) by a blower motor, and
then passes through the cooler unit and heater
unit before being blown out from each of the ducts.
The temperature control type at this time is the
reheat method.

Evaporator Heater core
2. With this method, the temperature is controlled by
changing the opening of a water valve that is
attached to the heater unit.
3. The air cooled by passing through the evaporator
is then warmed to the required temperature by the
heater core, where the flow is regulated by the
water valve.
4. The water valve is linked with the temperature
control switch on the control panel, and can be set
to any position desired.
