Application of Refrigeration and Heating Equipment in Chemical Industry


The dynamic temperature control system is suitable for temperature and temperature control of glass reactors, metal reactors and bioreactors. In the chemical and pharmaceutical fields, refrigeration and heating equipment is often temperature controlled in conjunction with the chemical reaction of the material itself. The temperature control of the material can be achieved by the temperature change of the medium in the jacket or coil.

For the temperature control of the cooling and heating integrated machine in the pharmaceutical industry, users have relatively high requirements for selecting temperature control equipment. Users require a wider operating temperature range than the commonly used temperature range. At the same time, different chemical reactions require different temperature profiles, and high temperature and low temperature integrated units need to work at different temperature points.

We know that some substances in chemical reactions are exothermic and some substances are endothermic, dynamic temperature control equipment needs to be able to cool and heat over the entire temperature range, in order to ensure the accuracy and stability of temperature control, also Need to dynamically respond to different set target temperatures. Therefore, the user’s requirements for the device are fast response, fast temperature switching and fast realization of target temperature changes.

cooling heating equipment

The refrigeration and heating integrated machine adopts electric heating, which can quickly increase the temperature of the circulating medium. It adopts energy-saving design, realizes the adjustment of cooling capacity, and can accurately control the temperature of materials, realize heat absorption of materials or rapid response to heat release, and meet the needs of pharmaceutical production in most industrial occasions.

The characteristics of the cooling and heating system are as follows:

(1) The cascade compression refrigeration cycle of the refrigeration unit can reach a lower temperature. The heating adopts electric heating, which can rapidly increase the temperature of the circulating medium.

(2) The adjustment of the cooling capacity change is realized. The refrigerant flow is mainly controlled by PID, and the material temperature is accurately controlled. However, the traditional approach is to use electrical heating to offset the cooling of the compressor, which wastes energy.

(3) The combined control of heating and cooling achieves a fast response to the absorption or release of heat by the material.

(4) The control of the material temperature is mainly realized by the refrigerant flow, and the refrigerant proportional control valve adopts the valve body of the electronic expansion valve. Higher temperature control accuracy can be achieved.

The temperature control of the refrigeration and heating system consists of a refrigeration cycle system, a heating cycle system and an automatic control system. For places with explosion-proof requirements for equipment, a positive pressure explosion-proof cabinet can be customized, which not only meets the explosion-proof requirements, but also reduces the number of explosion-proof components and reduces the production cost of the equipment.
