Product advantages
First, the advantages of low temperature refrigerators compared with liquid nitrogen:
1. The cost of using liquid nitrogen is 7-10 times the electricity cost of using low temperature freezing; (liquid nitrogen vaporization heat is 5.6KJ / mol = 200kJ / kg, refrigeration power is 1kw.h, and 18KG = 22 liters of liquid nitrogen is required) .
2. The low temperature refrigeration unit can accurately control the temperature, but the liquid nitrogen temperature control is difficult;
3. The transportation and storage of liquid nitrogen is very cumbersome, and production will be stopped once it is interrupted;
4. The use of liquid nitrogen is dangerous and requires a license.
Application advantages of high and low temperature integrated machine:
1. The load volume of general users is large. If the load requires uniform temperature, it must be filled with refrigerant, but a large amount of low-temperature refrigerant will turn into gas at normal temperature, and the volume and pressure of gas will be huge, and the equipment itself will not be able to meet it;
2. The load on the user's site is far away from the refrigerator room. The load area is usually clean, explosion-proof, and silent. The high and low temperature all-in-one machine can separate the cryogenic unit and the load area, making the entire system safer and more reliable.
3. Generally, the cooling capacity is used to cool the materials in the load through the heat exchange coils in the load. Once the heat exchange coils leak, the materials may be contaminated, and the refrigerant system usually uses the material solvent. Substances, so even if leaked, the possibility of contamination can be completely avoided;
4. The high and low temperature integrated machine is also a kind of carrier for storing cold energy. When the load changes greatly, it can be adjusted by the refrigerant. This is conducive to temperature control and energy saving. In general, the larger the load fluctuation, the more the amount of refrigerant required.
5. Heat exchange efficiency is higher than liquid nitrogen. Liquid nitrogen uses the latent heat of evaporation to release the amount of cold. After the liquid nitrogen absorbs heat, it becomes a gaseous state. The vapor-liquid two-phase mixed state occurs in the coil, which causes a large air resistance and the flow rate decreases sharply. Tube wall contact, heat exchange efficiency is greatly reduced. The refrigerant of the integrated machine generally uses dichloromethane (boiling point 40 ℃, freezing point -95 ℃), alcohol (boiling point 78 ℃, freezing point -114 ℃), dichlorofluoroethane (boiling point 32 ℃, freezing point -103 ℃), Trifluorodichloroethane (boiling point 28.7 ℃, freezing point -107 ℃), difluorochloroethane (boiling point -10 ℃, freezing point -131 ℃), non-toxic, non-flammable, environmentally friendly, low price. The circulation of the refrigerant uses a magnetic circulation pump to reduce the impact of pollution and low temperature on the bearing seal.

High and low temperature integrated machine performance characteristics:
1. Temperature adjustment range: -130 ℃ to +320 ℃, temperature control accuracy ± 0.5 ℃.
2. Refrigeration: It adopts cascade cooling, and the cooling capacity is from 1 to 1000KW.
3. Control system: programmable PLC plus touch screen
4. With RS485 and R232 interfaces, it can communicate with the computer, so as to accept the setting, control of the computer, and transmit the measured temperature to the computer.
5. Optional imported heat transfer fluid
6. The transmission pump adopts magnetic pump, no leakage, no pollution, high head
7, liquid storage barrels and pipelines are sealed and pressured to prevent volatilization of the refrigerant, dew and icing, and a liquid level indicator
8, small load heating can use the hot air bypass of the compressor to heat the load
9. Multiple alarm protections: water cut-off, water temperature too high, circulation pump failure, compressor overheating, pressure too high, overcurrent, phase loss, phase continuity, etc.
10. Cooling method: air-cooled or water-cooled can be selected, and air-cooled condenser can be placed outdoors; due to the many industries and uses of the unit, the model cannot be fixed, and most need to be customized according to the actual situation of the user.

product model:
1. How many degrees does the temperature need? What is the volume requirement?
2. What materials are processed? how much weight? Its specific heat capacity, heat of vaporization, heat of solidification?
3. How long does it take to cool down or heat up? Every production cycle?
4. Other heat loss: heat of reaction, heat of stirring, circulation pump, pipeline, liquid storage tank;
Based on the answers to the questions, the two sides discuss a better solution.
The main components of Hisilicon's high and low temperature all-in-one machines are all world-renowned brands. For example, the compressors mainly use Copeland, Bitzer, Danfoss, Alfa Laval, Siemens, Schneider, etc., large-scale systems use screw compressors and are equipped with economizers. Make the system more efficient. Small systems use semi-hermetic piston compressors. The high and low temperature all-in-one evaporator uses a stainless steel plate heat exchanger. The high and low temperature all-in-one machine provides the largest high-efficiency heat exchange area in a compact space.
