Working Principles

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

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

Table 2-9 The working principles of the TEC

Function Working principles Remarks

Cooling After the TEC applies a positive voltage to

semiconductor refrigeration chips, the

internal circulation side becomes cold, and

cold air is supplied to the cabinet through

the cold-end heat sink. The external

circulation side becomes hot, and heat is

dissipated through the hot-end heat sink.

Heat is transferred from the

cold end to the hot end to

realize refrigeration

The controller controls the

fans and semiconductor

refrigeration chips,

monitors the TEC04

operation, and generates an

alarm when a fault occurs.

Fans provided forced air in

both cold end and the hot

end, which speeds up heat

dissipation 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 through

the cold-end heat sink. The external

circulation side becomes cold, and heat is

dissipated into the Mini-shelter through the

hot-end heat sink.

Table 2-11 The working principles of the air conditioner

Air Conditioner

Working Principles Remarks

PC500 The refrigeration cycle is as follows:

1. The compressor draws refrigerant from the

evaporator and compress it to a high

temperature and pressure.

2. The compressor drives the high-temperature

and high-pressure refrigerant into the

condenser.

3. The refrigerant in the condenser is cooled into

high-pressure liquid.

4. The high-pressure liquid refrigerant transforms

into low-pressure refrigerant after passing

through throttles, and then enters the

evaporator.

5. The low-temperature and low-pressure

refrigerant transforms into gas after being

heated in the evaporator.

6. The compressor sucks the air refrigerant again.

The condenser and

evaporator are both

equipped with a

cycle fan to

strengthen air

convection and

heat exchanging.

The condenser

performs heat

exchanging

5.3 Cable Layout Principle

The 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 into

the 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 in

each compartment are routed along the rack. Cables are routed between compartments by

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

Mini-shelter.





53

Figure 5-1 Cable layout of the Mini-shelter

Table 5-4 describes the cable layout principle of the Mini-shelter.

Table 5-4 Cable layout principle

Item Principle

Cables routed

in the cabinet

The dedicated cable troughs and standard rack form an integrated

cable tray.

The dedicated cable troughs are on the left and right sides of the

device and operated from the front.

Cables between compartments are routed through the cable holes on

wall boards of the compartments.

Power cables and signal cables are bound separately.

Cables routed

out of the

cabinet

Cables are routed out of the compartment through the cables holes at

the bottom.

Feeders are routed out of the compartment through the feeder window.

Ground cables An indoor ground bar is installed next to the ACDB and is connected

to the site ground grid over a ground cable.

The ACDB, power system, and BTS are connected to the indoor

ground bar, and other devices is connected to the nearest ground bar.

Feeders The feeder window is installed on the wall board close to

communications equipment and uses carrier-class anti-damage and

waterproof design.

The contact part between the feeder window and the Mini-shelter is





54

Item Principle

sealed with waterproof tape, and the feeder window is secured from

the Mini-shelter interior by using bolts.

Dedicated waterproof connectors can only be tightened or loosened

from the Mini-shelter interior. The waterproofing level does not

change after the waterproof connectors are tightened. The feeder

window is secured with protective bars and cannot be tightened or

loosened from the Mini-shelter exterior.
