Cabinet TEC Air Conditioner
1 Overview
The TEC technology is based on the “Peltier effect ”of the semiconductor. When TEC chip ends connect DC,one End refrigeration, the other end is heating ,the temperature difference between the two ends can be as high as 68°C
Thermoelectric semiconductor (TEC) refrigeration mesh Former gradually become battery intelligent management technology, especially mobile communication base station outdoor battery cabinet constant temperature control The mainstream choice.
TEC air conditioning have counter-attack joint function, if the dc power supply cord joint reverse, TEC air conditioner doesn't work, back to normal after connection can work normally.
TEC technology has the following characteristics:
1. zero pollution, zero emissions. Safe and reliable;
2. small size, can be door-mounted. Facilitate the realization of the intelligent temperature control and remote monitoring;
3. continuous running, quiet operation. Maintenance-free;
4. can cooling and heating ,easy conversion.

3 .product features
1.TEC air conditioning should be able to automatically save the current running state and has the power self-start function.
2.Control functions: air conditioner running automatic control completely based on the internal temperature of the cabinet, Controller through internal cycle Ring temperature sensor Testing machine cabinet return air temperature,And set point comparing judgment ,to control internal and external fan or TEC module work.
3.1 Refrigeration
The cooling open point = cooling stop point + cooling sensitivity , when cabinet internal temperature exceeds cooling open point, start cooling operation.when the inside temperature lower than the cooling stop point, cooling operation stops.
cooling parameters set point
Parameter | The default value | Unit | Description of the set point |
The cooling open point (T1) | 35 | °C | The temperature point when the cooling start |
The cooling stop point (T2) | 25 | °C | The temperature point when the cooling stop |
cooling sensitivity | 10 | °C | The temperature point when heating start |
3.2. Heating
Heating stop point = heating open point + heating sensitivity, when cabinet internal temperature higher than heating open points, begin heating .when cabinet internal temperature higher than heating stop point ,heating operation stop.
Heating parameter set point
Parameter | The default value | Setting range | Unit | Description of the set point |
Heating start point (T1) | 5 | [-10 -15] | °C | The temperature point when the heating start |
Heating sensitivity (T2) | 5 | [5-10] | °C | The sensitivity of the temperature control |
3.3 Self-Test
The air conditioner self-test is for field detection use. Self-test procedures are as follows: LED light self-test two seconds, to check whether display normal.Internal and external fan and TEC module get through power to operate 20 second,Inside fan, outside fan and TEC module stop running 8 seconds
