Working Principles

A TEC provides two separate air circulation systems, one indoors and the other outdoors.

Table 2-9shows the working principles of the TEC.

Table 2-9The working principles of the TEC

Function Working principles Remarks

Cooling After the TEC applies a positive voltage to

semiconductor refrigeration chips, theinternal circulation side becomes cold, and

cold air is supplied to the cabinet throughthe cold-end heat sink. The externalcirculation side becomes hot, and heat is

dissipated through the hot-end heat sink.

Heat is transferred from the

cold end to the hot end torealize refrigeration

The controller controls thefans and semiconductor

refrigeration chips,monitors the TEC04

operation, and generates analarm when a fault occurs.

Fans provided forced air in

both cold end and the hotend, which speeds up heatdissipation from the heat

sink.

Heating After the TEC applies a negative voltage to

semiconductor refrigeration chips, the

internal circulation side becomes hot, and

heat is supplied to the Mini-shelter throughthe cold-end heat sink. The externalcirculation side becomes cold, and heat is

dissipated into the Mini-shelter through the

hot-end heat sink.

PC500 The refrigeration cycle is as follows:1. The compressor draws refrigerant from the

evaporator and compress it to a hightemperature and pressure.

2. The compressor drives the high-temperatureand high-pressure refrigerant into the

condenser.

3. The refrigerant in the condenser is cooled intohigh-pressure liquid.

4. The high-pressure liquid refrigerant transformsinto low-pressure refrigerant after passing

through throttles, and then enters the

evaporator.5. The low-temperature and low-pressure

refrigerant transforms into gas after beingheated in the evaporator.

6. The compressor sucks the air refrigerant again.

The condenser and

5.3 Cable Layout PrincipleThe AC power cable to the mains is routed into the power distribution equipment

compartment from the bottom of the cabinet to connect to the AC power distribution device.

Communications cables such as the intermediate frequency cable and feeder are routed intothe equipment compartment from the upper part of the compartment side panel. Then the

communications cables are routed along columns of the rack to connect to devices. Cables ineach compartment are routed along the rack. Cables are routed between compartments by

using cable holes reserved on the wall board.Figure 5-1shows the cable layout of the

Mini-shelter.
