4. Instruccions de configuració
The HKJ-K100 unit is pre-assembled. If you purchased Option B or C, the power supply and/or thermostat are included. For Option A, you will need to source a compatible 12V, 12A (or higher amperage) power supply and optionally a thermostat.
4.1 Connexió de la font d'alimentació
- Ensure the power supply is unplugged from the main power outlet.
- Connect the positive (+) and negative (-) wires from the HKJ-K100 cooling unit to the corresponding terminals on the 12V power supply. Pay close attention to polarity to avoid damage.
- If using a digital thermostat (Option C), connect it according to its specific wiring diagram, typically between the power supply and the cooling unit to control power based on temperature readings.
4.2 Instal·lació
The HKJ-K100 uses a magnetic fastener for mounting. Position the cooling unit in your desired application (e.g., inside a small refrigerator, incubator, or pet enclosure). Ensure adequate ventilation for the hot side of the unit to dissipate heat effectively. The cold side should be directed towards the area you wish to cool.
5. Funcionament
- Once the unit is securely installed and wired, plug the power supply into a suitable electrical outlet.
- The cooling unit will immediately begin to operate. The cold side will start to cool, and the hot side will dissipate heat.
- If using a thermostat (Option C), set your desired temperature. The thermostat will automatically turn the cooling unit on and off to maintain the set temperature, optimizing energy consumption.
5.1 Notes de rendiment
In tests, the HKJ-K100 unit achieved a lowest temperature of approximately -6°C within a 10-liter thick foam box at an ambient room temperature of 25°C. The cold side of the unit can reach very low temperatures, as demonstrated by a surface temperature of -36.2°C after one minute of operation with a refrigeration chip test.
6. Manteniment
- Neteja: Periodically clean the heat sinks and fans on both the hot and cold sides to ensure optimal airflow and cooling efficiency. Use a soft brush or compressed air to remove dust and debris.
- Inspecció: Reviseu regularment totes les connexions del cablejat per assegurar-vos que estiguin ben fixades i que no estiguin danyats.
- Frost Management: If excessive frost builds up on the cold side, it may reduce cooling efficiency. Defrost the unit by temporarily turning it off.
7. Solució De Problemes
- La unitat no refreda:
- Check if the power supply is properly connected and receiving power.
- Verify that the positive and negative wires are connected correctly (polarity).
- Ensure the power supply is providing the correct voltage (12V) and sufficient current (12A or more).
- Check for any obstructions to the fans or heat sinks.
- Refrigeració insuficient:
- Clean any dust or debris from the heat sinks and fans.
- Ensure the hot side has adequate ventilation to dissipate heat.
- Check if the ambient temperature is too high for the desired cooling effect.
- Verify the thermostat settings if applicable.
- Soroll excessiu:
- Check if the fans are obstructed or if any wires are touching the fan blades.
- Ensure the unit is securely mounted and not vibrating against other surfaces.
8. Consells d'usuari
- For best performance, use the HKJ-K100 in an insulated enclosure to minimize heat exchange with the environment.
- Consider adding thermal paste between the cooling unit and any surfaces it's directly cooling for improved heat transfer.
- When integrating into a custom project, plan for proper airflow to both the hot and cold sides of the unit.
- If using for an incubator, a precise thermostat (Option C) is highly recommended for stable temperature control.
