Figure 9: HMI Controller
HMI Controller
The TriPac HMI (Human Machine Interface) Controller is
installed in the truck cab, typically on a wall in the sleeper
compartment. It is easily accessible to the driver and controls
TriPac operation. Standard, typically used operating
parameters are enabled in the HMI Controller when TriPac is
installed. If necessary, HMI operating parameters can be
adjusted through programming by your Thermo King dealer.
Compressor
The TriPac air conditioning compressor is mounted in the
TriPac APU and is driven by the TriPac engine. Refrigeration
lines connect the compressor to the TriPac air conditioning
condenser on the back wall of the truck cab and the evaporator,
usually mounted under the truck sleeper compartment bunk.
Compressor operation is controlled by the TriPac Interface
Board. The Interface Board receives instructions from the HMI
Controller. The HMI Controller will instruct the Interface
Board to start the TriPac engine and energize the compressor
clutch when cab cooling is needed. The refrigeration system is
protected by high pressure and low pressure cutout switches.
Control Circuits
The control circuits operate on 12V DC supplied by the truck
batteries.
