2. Description
Thermoelectric cooler (TEC) is mainly made of semiconductor refrigeration piece, heat sinks, fans, panel. TEC is small, light, easy to install. No refrigerant, no pollution to the environment, cooling and heating functions are interchangeable, can be connected with an external emergency fan and hydrogen fan, can be remotely monitored though RS485.
When the DC flow through the circuit, which is formed by different conductor connection in nodes produces endothermic or exothermic phenomenon, this phenomenon called peltier effect. TEC use in this peltier effect. When TEC power on, one side cooling through the fan and the heat sink to absorb heat, contained in the other side of the heating through the fan and heat sink get heat away.
Operate by inside fan with the highest speed , don’t adjust speed .
| Default parameter | By inside fan(RPM) |
| With the highest speed by inside fan | 3600 |
| Default parameter | Cabinet return air temperature(°C) | Speed of outside fan(RPM) |
| Start adjust(low speed) | 30 | 1800 |
| End adjust(highest speed) | 32 | 3600 |
4.3. Refrigeration
When the temperature is higher than refrigeration open points then operate refrigeration. When the temperature is lower than refrigeration open points then stop. When set the temperature, stop temperature should be lower than start temperature.
Refrigeration parameter Settings
| Parameter | Default Value | Scope | Unit | Set point to describe |
| Sensitivity of refrigeration | 2 | [1~5] | °C | Refrigeration operation to stop back to the poor |
| Start point of refrigeration | 30 | [15~60] | °C | Refrigeration operation start temperature point |
When the temperature is lower than heating point then start heating, when the temperature is higher than heating point then stop. The start temperature should be lower than stop temperature.
Heating parameter Settings
| Parameter | Default Value | Scope | Unit | Set Point To Describe |
| Start point | 5 | [-10~15] | °C | Start temperature |
| Stop point | 15 | [-5~25] | °C | Stop temperature |
The controller can do hydrogen discharging , default every 24hours discharge 5 minutes.
The current time must be longer than switch delay time when hot and cold switching , you can set , the default time is 5min.
The controller includes timing function for hydrogen , the default time is 5min every 24hours.
The controller can memory the current state , can start when the power outages.
Controller fault protection start when the input voltage is smaller than under-voltage alarm or larger than the over-voltage alarm;
Voltage recovery is between under-voltage and over-voltage , the controller will normally operate.
TEC can connect with computer by RS485 , user can check system state by monitor background ( including fan , TEC , sensor) and change parameter.
Communication parameters: Baud rate 9600 BPS( can be set ):
Data bits:eight；
Stop bits:one；
Parity:none
