Low Temperature Incubator Refrigeration Working Principle:
The refrigeration system of a low-temperature incubator operates on the principle of an inverse Carnot cycle, which consists of two isothermal and two adiabatic processes. The cycle begins with the refrigerant being adiabatically compressed by the compressor, increasing its pressure and temperature. This high-pressure refrigerant then passes through a condenser, where it undergoes isothermal heat rejection to the surrounding environment. After that, the refrigerant expands adiabatically through a throttling valve, causing its temperature to drop significantly. Finally, the cooled refrigerant absorbs heat from the object to be cooled in the evaporator, thus lowering its temperature. This cycle repeats continuously to maintain the desired low temperature. The incubator's refrigeration system uses a dual-stage Freon refrigeration system featuring a fully enclosed Taikang compressor from France. Energy adjustment technology is integrated into the design to ensure stable operation and optimal energy efficiency. The system employs Balanced Temperature Control (BTHC), allowing for precise regulation. When operating, the control system adjusts the heater output based on PID calculations, maintaining a dynamic balance between heating and cooling to achieve the set temperature accurately and consistently.Low Temperature Incubator Operation Process:
Control Panel Features:
1. **Power Switch:** Labeled “POWER,†turn the switch to the “I†position to activate the device. 2. **Temperature Setting:** Use the “SET TEMPERATURE†button with up/down arrows to adjust the desired temperature. 3. **Over-Temperature Protection:** Set the over-temperature limit using the “SET OVERTEMPERATURE†knob, which can be adjusted from 0 to 10 for added safety. 4. **Heating Lamp:** The “HEATING ACTIVATED†indicator light shows when the unit is actively heating. 5. **Over-Temperature Protection Lamp:** The “OVERTEMPERATURE ACTIVATED†light indicates when the protection mechanism is engaged. 6. **Day/Night Program Controller:** A 24-hour timer divided into two 12-hour segments for day and night settings. 7. **Lighting Controller:** Controls lighting cycles using a 24-hour scale. 8. **Fuse:** Located near the power inlet at the bottom, this provides protection against voltage fluctuations. If blown, it must be replaced to restore operation.Basic Operating Procedures:
1. Turn on the power and set the over-temperature protection knob to the maximum. 2. Place a calibrated thermometer in the center of the incubator for accurate readings, avoiding contact with shelves or walls. 3. Ensure proper air circulation around the incubator for even temperature distribution. 4. Avoid placing open containers inside, as moisture evaporation may increase frost buildup on the floor. 5. Set the desired temperature by entering the setting mode, adjusting the value using the up/down buttons. 6. Once stable, compare the internal temperature with the thermometer and perform calibration if needed. 7. Adjust the over-temperature protection by turning the knob clockwise until the light turns on, then back slightly for safe margin. 8. Use the “SET DAY/NIGHT†and “SET LIGHT TIME†controls to manage time-based settings. Each dial has 96 segments, each representing 15 minutes. 9. Connect external devices only if they do not exceed 1A and do not generate excessive heat. 10. The outer casing may feel warmer than ambient due to heat dissipation during operation.Metal Dish Rack,Metal Dish Drainer,Metal Dish Drying Rack,Metal Plate Rack
