IIIWuhan desktop high and low temperature alternating test chamberRefrigeration system:

1. Refrigeration compressor: Adopting imported fully enclosed Taikang refrigeration compressor, it has the characteristics of high efficiency, low noise, and strong reliability. The refrigeration system adopts a single-stage refrigeration method, and R404A refrigerant ensures stable operation in a low temperature environment of -40 ℃, providing * cooling capacity.

2. Condenser: Air cooled condenser, with fins made of high heat dissipation materials, combined with low-noise axial flow fans, can effectively dissipate the heat generated by the refrigerant during compression to the environment, ensuring the efficient operation of the refrigeration system.

3. Evaporator: High quality copper tube covered aluminum fin evaporator is used, which increases the heat exchange area and improves the refrigeration efficiency. Reasonable refrigerant distribution device is designed inside the evaporator to ensure uniform evaporation of refrigerant and achieve rapid cooling.

4. Expansion valve: By using electronic expansion valves, the refrigerant flow rate can be accurately adjusted according to the actual operating conditions of the refrigeration system, improving the stability and energy efficiency of the refrigeration system.

4、 Heating system:

1. Heating element: Using nickel chromium alloy electric heating wire, it has the advantages of high heating efficiency, long service life, and good stability. The heating wire is evenly distributed in the air duct inside the test chamber, and through circulation, the fan blows the heated air evenly into the test chamber to achieve rapid heating.

3. Heating control: PID intelligent control algorithm is adopted to automatically adjust the heating power based on the deviation between the actual temperature in the test chamber and the set temperature, ensuring the accuracy and stability of temperature control.

5、 Control system:

1. Controller: Equipped with a 7-inch color touch screen programmable controller, the operation interface is simple and intuitive, which can easily set and modify parameters such as temperature and time. The controller has multiple control modes and can achieve functions such as constant value control and program control to meet different testing requirements.

2. Sensor: High precision platinum resistance temperature sensors are used, installed in evenly distributed positions inside the test chamber, to collect real-time temperature data inside the chamber, and transmit the data to the controller for processing and display. Sensors have the characteristics of fast response speed and high measurement accuracy, ensuring the accuracy of temperature control.

3. Communication interface: The test box is equipped with an RS485 communication interface, which can communicate with the upper computer to achieve remote monitoring and data transmission. The upper computer software can display real-time information such as the operating status and temperature curve of the test box, and can remotely control and modify the parameters of the test box.

6、 Box structure:

1. Inner box: The inner box is made of SUS304 stainless steel material, with a smooth surface, corrosion resistance, and easy cleaning. Can meet the testing needs of small batch components.

2. Outer box: The outer box is made of cold-rolled steel plate with spray coating treatment, which has good rust and corrosion resistance performance. The overall structure is compact and occupies a small area, making it suitable for use on a desktop.

3. Insulation layer: The insulation layer of the box is made of high-density polyurethane foam material with a thickness of 100mm, which has good insulation performance and can effectively reduce the heat transfer inside and outside the test box, thereby reducing energy consumption.

4. Observation window: There is a large observation window on the door of the test chamber, which is made of double-layer tempered glass and filled with inert gas in the middle. It has good insulation and anti fog performance, making it easy to observe the testing situation of the samples inside the test chamber.

5. Sample rack: The test chamber is equipped with two layers of stainless steel sample racks, which can be adjusted according to the size and shape of the samples for easy placement. The sample holder adopts a special design to ensure that the sample is not affected by airflow during the testing process, ensuring the accuracy of the test results.

7、 Security protection system:

1. Over temperature protection: The test chamber is equipped with an over temperature protection device. When the temperature inside the chamber exceeds the set over temperature protection value, the heating system will automatically stop working and emit an audible and visual alarm signal to prevent damage to the sample due to over temperature.

2. Leakage protection: The test box is equipped with a leakage protection switch. When a leakage fault occurs in the equipment, the leakage protection switch will immediately cut off the power supply to protect the personal safety of the operator.

Overload protection: Equipment such as refrigeration compressors and circulating fans are equipped with overload protection devices. When the operating current of the equipment exceeds the rated current, the overload protection device will automatically cut off the power supply to protect the equipment from damage.

3. Phase sequence protection: The power input of the test box adopts a three-phase five wire system and is equipped with a phase sequence protection device. When the phase sequence of the power supply is incorrect, the phase sequence protection device will automatically cut off the power supply to prevent equipment damage due to phase sequence errors.

8、 Installation and Debugging:

1. Installation environment: The test chamber should be installed in a well ventilated, dry, and non direct sunlight area, with sufficient space left around for equipment maintenance and upkeep. The installation ground should be flat, firm, and able to withstand the weight of the equipment.

2. Installation steps: Move the test box to the installation position and adjust the levelness of the equipment. Connect the power and communication cables of the device to ensure a secure connection. Connect the power supply and check if the device is powered on normally.

3. Debugging: After the equipment installation is completed, it will be debugged by professional technicians. The debugging content includes temperature calibration, refrigeration system debugging, heating system debugging, control system debugging, etc. After debugging is completed, conduct a trial run of the equipment to check whether its various performance indicators meet the requirements.
