Punching and Taiwan; Germany Each type is carbon oxide welding machine and argon welding machine.Ten.Multiple unitsAutodrsk. Invente 3D Drawing software, Proceed3D Shetate metal disassembly and design virtual assembly.
2. The shell is made of high-quality galvanized steel plate. Add electrostatic powderSpray baking paint at the end;
3. The inner box adopts importedSUS#304Stainless steel, argon arc welding full welding process, prevent the high temperature in the box high-humidity air leakage and penetration. The rounded corner design of the inner box. It can better discharge the condensate water of the side wall.

Refrigeration system technology
3D Refrigeration system management drawing   Frequency conversion control technology of refrigeration system. In the variable frequency refrigeration system. Even if the power supply frequency50HZ. It is fixed. It can be through the frequency converter. Change the frequency. So as to adjust the compression speed so that the amount of cold changes continuously. Ensure the operating load of the compressor. Match the actual load in the test chamber (that is, as the temperature in the test chamber rises, the compressor frequency rises, Increase the cooling capacity. On the contrary, the frequency of the compressor is reduced. Reduce refrigeration quantity. Greatly save transportation. Unnecessary loss when running, achieve the purpose of energy saving. It can still be used when the test chamber is just running. Improve the frequency of the compressor and the ability of the refrigeration system. Achieve rapid coolingThe purpose of. The test chamber adopts a variable frequency refrigeration system. It can accurately control the temperature in the box, so that the temperature in the box. Constant degree, the temperature fluctuates little. At the same time, it can also ensure the suction and exhaust pressure of the refrigeration system.

Refrigeration system technology and other energy-saving technologies
1. UsePID.+PWM. Principled VRF. Technology (electronic expansion valve according tothermal energy cold and beautiful flow control in working conditions)PID.++PWM.Principled VRF. Technology (system   Refrigerant flow control). The technology realizes low-temperature energy-saving operation (electronic expansion is based on what can be the cold and beautiful flow servo control technology in working conditions?) ; Low-temperature working state, put one thing on top of another. The heater does not participate in the work, pass PID.+PWM.Regulate the flow rate and flow of refrigerant to the three-way flow adjustment of refrigeration pipeline, cold side pipeline and heating side pipeline, realize the automatic constant temperature of the work. This method is under low-temperature working conditions. Approve Realize the automatic constantity of the studio temperature. This method is under low-temperature working conditions. It can reduce30% of energy consumption. This technology is based on Denmark Dan-foss. Company's ETS System electronic expansion Valve. It can be applied to the adjustment of refrigeration when different refrigeration capacity requirements, both when meeting the requirements of different cooling rates. Realize the cooling capacity adjustment of the compressor.
2. Size2Set compressor group design technology. Automatic start-stop according to load conditions (The big series is designed). Configuration of refrigeration unit1. The binary compound composed of a semi-closed compressor. Stacked refrigeration the system is added to a fully dense single-stage refrigeration system. Configure the female; according to the box. The load condition and cooling rate require the intelligent opening of different compressor units, so that the box. The internal cooling capacity working condition and the compressor output power are the best match. So that the reality. Now the compressor is round in the best working condition range to extend the service life.

Cut out Cold Circuit technology
The power distribution layout operation is based on the power distribution assembly drawing issued by the technical department to install electrical parts and select internationally well-known brands:
Omron, Sch-neider, Germany Phoenix Terminal block. The line code is clearly marked. Choose the old brand in China. Brand name, (Pearl River Cable) ensures the quality of the wire; Minimum selection of control lines 0.75 Square RV Soft copper wire. All major loads, such as motor compressors, are based on EC. The cable groove wiring safety current standard selects the trap diameter! PressShrink machine. The cable port of the machine cable box is treated with sealant. Prevent frost from short-circuiting the terminal in the junction box. All terminal fixing screws are connected with standard fixed torque. Make sure that it is fast and reliable. Prevent loose fire and other hidden dangers!

Refrigeration series process
1. Standardize
1.1 High-quality steel pipe piping process and welding standardization;
according to the standard pipe layout, ensure the stability and reliability of the model system;
1.2 Imported Italian imported pipe bending machine steel pipe whole bending. Significantly Reduce the welding point and the oxide in the tube generated during welding, and improve system reliability.

Shockproof and support of pipelines
2.1 MENTEK has strict requirements for the support and shock prevention of refrigeration copper pipes. Fully consider the management. In the road seismic protection situation, add arc bends to the refrigeration pipeline and adopt special nylon fixed clamping. The way, avoid pipe deformation and leakage caused by circular vibration and temperature changes. Improve the reliability of the whole refrigeration system.
2.2 Oxidation-free welding process. It is well known that the cleanliness inside the pipeline of the refrigeration system is directly related to refrigeration system. The efficiency and operating life; MENTEK adopts standardized operation of charging welding. Avoid a large amount of oxide pollution in the pipe during welding.
