How to Choose the Right Cooling and Heating System?

How to Choose the Right Cooling and Heating System?

The refrigeration and heating system can effectively improve the working efficiency of the equipment in the process of temperature control, and can be used with a variety of instruments, and the cooling capacity is large and the cooling speed is fast, which reduces the required energy consumption. It is very important to choose a suitable cooling and heating system. It is necessary to understand the internal structure and technical status to ensure that the equipment is always in good working condition. The equipment mainly adopts a fully enclosed imported refrigeration compressor, a fluorine-free refrigeration system and multiple protection devices such as overheating, overcurrent, and overpressure. To the experimental container cooling or constant temperature effect.

First, the parameters that need to be provided when purchasing a cooling and heating system

Before purchasing equipment, customers need to provide the temperature range required by the equipment, which industry is used for which equipment, temperature control accuracy, heating and cooling rate, cooling capacity, supporting reactor size, material, quantity, and reactor materials.

Second, many factors need to be considered when purchasing a cooling and heating system

Various factors should be considered when purchasing a refrigeration and heating system, such as heating power, circulation pressure, cooling capacity, flow rate, etc. Various working conditions require different types of refrigeration and heating systems. If the model of the cooling and heating system is improperly selected, the running time of the equipment will be slightly affected, resulting in an increase in the cost of use, and in severe cases, the equipment will not be able to operate.

① Determine the basic requirements of the reactor during the temperature control process of the reactor. The temperature control requirements of the reactor are different, and the material, quantity, inlet temperature, inlet temperature, and accuracy requirements are different, so the corresponding refrigeration and heating system models are also different. Users need accurate process data, and then choose the appropriate one according to these data. model.

② Determine the model of the refrigeration and heating system. The heat transfer oil of the refrigeration and heating system is generally a special heat transfer oil. According to the temperature requirements of the reactor, the type of reaction medium of the refrigeration and heating system can be determined, and the supporting preparations can be made. For some special environments, the cooling and heating system can also customize the type of isolation and explosion-proof according to the corresponding requirements, with corresponding explosion-proof grades.

③ Determine the parameter configuration of the refrigeration and heating system. After the user provides the manufacturer with accurate operating data, the manufacturer will provide the corresponding cooling and heating temperature control scheme after calculation. In the scheme, the cooling and heating system model and parameter configuration will be selected. The user can see the brand of each accessory in the parameter configuration , the manufacturer will provide the corresponding cooling and heating control scheme after calculation. Some accessories have a variety of brands to choose from. If users have requirements, they can contact to modify. Generally, it is a standard configuration, but it can also be customized.

④ Determine the size of the cooling and heating system. The location and environment of the cooling and heating system should also consider the size and size, and reserve a corresponding ventilation location for the equipment.

Third, configuring a suitable cooling and heating system requires understanding the parameters of the reactor.

For different types of reactors, choose according to different temperatures and reaction materials. Different needs have different requirements for the heating and heat conduction methods of the reactor. It is necessary to pay attention to how much temperature and how long it takes for the materials in the reactor to be heated to the required temperature, so as to reduce unnecessary power loss as much as possible.

① It is necessary to consider factors such as the size of the reactor, the volume of the jacket or coil of the reactor, and whether the reacting material is exothermic or endothermic.

② What is the temperature of the reactor, what are the requirements for the temperature, and how long does it take to preheat.

③Are there any special requirements for heating or cooling equipment? In the absence of temperature control, if it is exothermic, how many degrees will the temperature rise in one hour.

④The parameters of the material in the reactor: density, specific heat, viscosity, etc.

⑤ How big is the inlet and outlet of the reactor jacket, and whether refrigeration or explosion protection is required.

⑥ Process requirements of the reactor.

How to choose high and low temperature all-in-one heating and cooling system?

The refrigeration and heating system is heated by heat transfer oil, circulated to the jacket layer of the reaction kettle through the circulation pump, and performs a periodic cycle between the pipeline and the jacket. The unique heating design, the temperature is automatically controlled to quickly reach the temperature required by the product process, Using intelligent PID control technology, it can be heated to a constant temperature or cooled, and the temperature control accuracy is high. The internal pipeline of the heat conduction oil heater is integrally formed with stainless steel, the heat loss in the tube is small, and the heating is uniform. Pipeline explosion-proof device, unique heating design, wide temperature control range, accurate, uniform and stable temperature. The heat conduction speed is fast, the heating and cooling speed is fast, the temperature is self-controlled, and the temperature requirements of various products can be quickly reached.

What are the main heating devices in the refrigeration and heating system? Jacket, coil (inner coil and outer coil), the principle of action is indirect heating, which is to pass cold and hot media into the jacket and coil to heat up or cool down. According to the required production process, the reaction The upper limit of the required working temperature of the kettle is set. If the temperature is lower than a certain temperature, it will be automatically heated, and if it is higher than a certain temperature, it will stop heating, and it will automatically cut off the power supply and stop heating. This is repeated to maintain the continuity of the working temperature in the kettle. The duration depends on the production process Be sure to pay attention when configuring the cooling and heating system.

The refrigeration and heating system can realize refrigeration and heating through one device, and is widely used in petroleum, chemical industry, electronic instrumentation, physics, chemistry, bioengineering, medicine and health, life science, light industry food physical property testing and chemical analysis and other research and enterprise The quality inspection and production department provides a field source with controlled cold and heat and uniform and constant temperature. It is very important to choose a suitable cooling and heating system, which can greatly improve the quality of the product and reduce the production cost to a certain extent.
