What is an Explosion-Proof Refrigeration and Heating System?
Explosion-proof heating and cooling machine is a temperature control equipment that is widely used in pharmaceutical, chemical, biological, laboratory, new energy, components and other industries to provide cold source heat source. So, how much do you know about this type of equipment?
First, the working principle of explosion-proof heating and cooling machine:
1. The explosion-proof circulating cold and heat integrated machine achieves the purpose of refrigeration, heating, constant temperature and separation in various experiments such as reactors, reactors, drying equipment, mixing equipment, separation equipment, and heat transfer equipment.
2. The explosion-proof heating and cooling machine is a temperature control device with two functions of cooling and heating. It passes the heat transfer medium from the oil tank to the equipment, and then returns to the oil tank from the equipment. The equipment controller can control the temperature of the fluid measured by the sensor. Fluid temperature to regulate device temperature.
3. The explosion-proof cooling and heating integrated machine uses compressors for refrigeration at high temperature, which is often referred to as the single-machine self-cascading refrigeration technology. It can perform exothermic reactions at high temperatures without changing the heat transfer medium. The compressor refrigeration technology brings Remove excess heat.
4. The explosion-proof cooling and heating integrated machine adopts the cooling and heating dynamic temperature control technology, which can transmit the temperature of the liquid inlet and outlet and the material in real time, control the heat absorption and release when the temperature difference is large, and use the heat conduction medium to control the temperature.
5. The explosion-proof refrigeration and heating integrated machine adopts a fully enclosed pipeline design and uses a plate heat exchanger, which reduces the demand for heat transfer fluid and improves the thermal energy utilization rate of the system to achieve rapid temperature increase.
Second, the characteristics of explosion-proof heating and cooling machines:
1. The explosion-proof circulating cooling and heating integrated machine adopts a fully enclosed system. There will be no oil mist at high temperature, and no moisture in the air will be absorbed at low temperature. The system will not increase the pressure due to high temperature during operation, and the heat transfer medium will be automatically supplemented at low temperature.
2. The explosion-proof refrigeration and heating equipment has a self-diagnosis function, and the protection function can be turned on in time if an abnormality occurs during the operation of the equipment.
3. The circulating pump of the explosion-proof cooling and heating integrated machine outputs the heat-conducting fluid to heat the materials in the supporting equipment.
4. The explosion-proof circulating cooling and heating integrated machine is equipped with an exhaust valve, which is convenient for replenishing circulating liquid into the equipment.
5. The explosion-proof hot and cold machine is equipped with over-temperature alarm function, overload and over-current protection functions. The temperature control adopts PID method, and the temperature control accuracy is high.
6. The explosion-proof temperature control system adopts a fully closed system, and the heat transfer fluid circulation system is sealed to prolong the service life of the heat transfer fluid.
Third, factors that should be considered when choosing an explosion-proof refrigeration and heating system:
1. The selection of explosion-proof circulating cooling and heating integrated machine needs to consider the size, weight, material and other factors of the reactor or reactor.
2. Consider the reaction temperature requirements, temperature control accuracy, jacket temperature, temperature control time, etc.
3. The viscosity and density of the reaction medium of the explosion-proof cooling and heating integrated machine and the corresponding medium selection.
4. Consider choosing air-cooled or water-cooled, and you can customize the isolation explosion-proof model.
5. Consider the size and size of the device model to see if the placement environment is satisfactory.
