2. The choice of refrigeration capacity is larger than your requirements, and the variable load adjustment is convenient. You can choose a slightly larger gear.
3. A model with mature operation practice.
Refrigerator is a machine that achieves refrigeration effect through vapor compression or absorption cycle. These liquids can flow through a heat exchanger to cool air or equipment. The vapor compression refrigerator includes four main components of the vapor compression refrigeration cycle (in the form of compressor, evaporator, condenser and some metering devices), and these machines can realize different refrigerants. The absorption refrigerator uses benign silica gel as desiccant. The absorption refrigerator takes water as the refrigerant and relies on the affinity between water and lithium bromide solution to achieve the refrigeration effect. In most cases, pure water is frozen, but water may also contain a certain percentage of ethylene glycol and/or corrosion inhibitor; Liquids such as thin oil can be frozen.
The unit can provide low-temperature refrigerant at 0℃ ~- 125℃. Suitable refrigerants include CaCl2 aqueous solution, ethylene glycol aqueous solution, ternary mixed solution (40% ethylene glycol, 40% water, 40% ethanol), R22 and other recognized refrigerants. Suitable for all kinds of places with low-temperature cold source requirements, such as reactors in pharmaceutical, chemical and other industries.
