How does the cooling and heating system achieve simultaneous temperature control?
Temperature control system The thermostat has heating and cooling functions, and can use the same medium for continuous temperature control from -120℃~320℃. The heating and cooling system of cooling and heating system is mainly composed of four parts: heat exchanger, compressor, evaporator and condenser, and it is also one of the very key components of the whole high and low temperature integrated machine. The heat exchanger is mainly to transfer heat from the hot fluid to the cold fluid, the...

What are the applications of Industrial temperature control machine chillers?
Industrial temperature control machine chillers are divided into oil-cooled and water-cooled according to the temperature and medium. The medium used is different for different temperatures, water can be selected for normal temperature, heat transfer oil for high temperature, and refrigerant for low temperature. According to the different cooling methods, it can be divided into air cooling and water cooling. Consider the ambient temperature of the industrial temperature control machine chil...

Temperature control instructions for stainless steel reactors and glass reactors
Reactor is a kind of reaction equipment in industrial production. It generally needs to be refrigerated or heated. Whether the temperature is suitable or not directly affects its reaction effect. Therefore, if conditions permit, it is generally equipped with a reactor temperature control device. The temperature control device of the reaction kettle uses the conversion of heat conduction oil to heat the material to be heated. Inferior heat conduction oil has a short service life and is prone ...

What are the conditions for the decarboxylation reaction? How to control the temperature of heating?
The decarboxylation of aromatic acids is easier than that of fatty acids. For example, benzoic acid can be decarboxylated by adding a little copper powder as a catalyst in quinoline solution and heating. When a strong electron-withdrawing group is attached to the α-C of the carboxylic acid, heating can make it decarboxylate more smoothly. For example: when the ortho-diaromatic organic acid is heated, it is easy to remove a carboxyl group, but when the temperature is low, an acid anhydride wi...
