The working principle of chemical refrigeration thermostal

The thermal power and the pressure and flow of the heat transfer medium are also factors to be considered in the selection of thermostats for refrigeration and heating for the chemical industry. Different raw materials have different characteristics, and they have different processing technology chatacteristics.

Chemical refrigeration and heating thermostat is more and more popular in the market because of its advantages in refrigeration and heating temperature control system. The overall solutions they create cover the pharmaceutical, chemical, new energy vehicles, light industry, petrochemical, environment, medicine and environmental protection, military industry, fine and daily chemical industry has been widely used, and its application scope and field is still expanding.

It works by pumping a heat transfer medium (usually water or oil) from a tank with a fuilt-in heater and cooler to the reactor and back from the rector to the tank. The controller adjusts the temmperature of the hot fluid according to the temperature of the hot fluid measured by the temperature sensor and /or the internal temperature of the reactor to adjust the temperature of the reactor. According to the type of heat transfer medium used. It can be divided into water type, pressurized water type or oil type.

The implementation of the cooling and heating thermostat includes a cooling and heating thermostat based on the temperature of a hot fluid, a cooling and heatign thermostat based on the temperature of a reactor, and a combination of seberal methods. Users should investigate the operation of special refrigeration and heating thermostat for chemical industry according to the actual situation, and select the products that meet their own temperature control precision requirements.

Temperatre sensors for cooling and heating the thermostat for reactor temperature are installed inside the reactor. The control panel sets and displays the same temperature as the reactor temperature, which is suitable for situations where the temeprature control accuracy is higher. Currently, most chemical cooling and heating thermostats use PID control technology to compenstae for various factors affecting reactor temperature.

Chemical refrigeration heating thermostat is composed of refrigeration cycle system. Heating cycle system and automatic control system. For the area with explosion-proof requirements, the positive pressure explosion-proof cabinet can be customized, which not only meets the explosion-proof requirements, but also reduces the number of explosion-proof parts and reduces the production cost of the whole machine.
