1.Description
The TEC air conditioner is a full automation temperature control
device. It uses intelligent controller to control the whole system
of the air conditioner. According to the variation of environment
temperature, the intelligent controller can automatically detect
and operate . The product is widely applied in telecom cabinet,
small and medium sized telecom room, UPS room, outdoor base station
room, etc. The TEC air conditioner includes the following specs:
100W, 200W, 250W, 350W, 400W, etc. In addition, it also can be
custom made.
2. Technical Specs
2.1 General Description
The TEC air conditioner consists of 6 parts: peltier module
(including sealing and insulation material), cold end radiator, hot
end radiator, cold end fan, hot end fan, monitoring module. When
power supply is connected to the TEC, one side of the peltier
conduct cooling, and the other side of the peltier conduct heating,
the cool (heat) from which will diffuse to the surrounding
environment through cold (hot) end radiators and fans. The cold end
radiator and cod end fan constitute the inside circulation for
cooling the cabinet internal environment, while the hot end
radiator and hot end fan constitute outside circulation for heat
radiation to the external environment.

Both the inside circulation and outside circulation air ducts adopt
air inlet through middle fans and air outlet through radiators at
the two sides.
