冷凍・暖房サイクル温度制御システム

In the selection process of the cooling and heating cycle temperature control system, the heating power, cooling power, pressure and flow rate of the equipment are the factors that the user needs to consider. performance.

1. As far as the heat transfer medium itself is concerned, it is very economical and environmentally friendly to use water as the heat transfer medium. Even if leakage occurs, it can be directly discharged without polluting the environment. However, water is easy to corrode and foul the water tank and flow channel, so in addition to pretreatment with anti-corrosion agent, rust should be removed regularly during use.

2. Using heat transfer oil as the heat transfer medium, the thermal conductivity is only 1/3 of that of water, the cost is relatively high, and it is easy to coke. The special application environment is also an important factor to consider when selecting equipment.

3. The realization of temperature control is based on the control of the temperature of the thermal fluid, the control based on the temperature of the reactor, and several methods of combined temperature control.

4. The user should investigate the realization of the fully enclosed operation of the refrigerating and heating circulator according to the actual situation, and select the fluid that can meet the temperature control accuracy of his own.

5. Based on the thermal fluid temperature control, the temperature displayed on the control panel is not consistent with the temperature of the equipment. Due to the differences in factors such as cycle, speed, temperature and ambient temperature, the temperature of the reactor fluctuates relatively large, and the temperature sensor is installed in the reactor. Internally, the temperature set and displayed on the control panel are consistent with the temperature of the reactor, which is suitable for high temperature control requirements.
