Heating System Parameter
2. Blower
Blower is located at the lower part of the goods
compartment. The door inside the blower case is con-
trolled by the servomotor. The exchange of the air in-
side and outside the door can be achieved by adjusting
the door to import the outdoor air and recirculate the
indoor air.
Blower motor uses Permenant magnet DC motor with multple blade fan. In addition, there are a set of
resistance on the blower which adjust the fan, called as adjusting resistor. Blower provides wind supply not
only to the heating radiator, but also to the evaporator in the refrigeration system.
3. A/C Control Mechanism
A/C control mechanism is located in the middle of the instrument panel. All adjustment except the A/C switch
and inside and outside circulation switch are made by rotating the control knob. The A/C control panel is
shown in Figure 4.
1 Temperature adjustment control knob: control the mix ratio of the cold and hot air by adjusting the air mix
door, use the control knob to achieve continuous temperature adjustment.
2 Outlet control knob: use 4 ranges, different types of air flow adjustment available.
3 Inside and outside circulation switch: It can toggles between the introduction of outdoor air and recirculation
of the indoor air. (press the switch for inside circulation)
4 Blower switch: when the plum blossom range is closed, the remaining four ranges are used to adjust the
air flow.
5 A/C switch: as the switch of the refrigeration system, use press-button with built-in A/C indicator.
