Product Description

Working principle of compressor
Compressor, the driven fluid machine that elevates low pressure gas into high pressure gas, is the heart of the refrigeration system. It inhales low temperature and low pressure refrigerant gas from the suction pipe, drives the piston to compress it through the motor operation, and discharges high temperature and high pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, so as to achieve the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).
Linear compressor, is the use of magnetic levitation principle and spiral circulation physical structure, compression of gas, to provide power for refrigeration.
Compressors are piston compressor, screw compressor, centrifugal compressor, linear compressor and so on. The piston compressor is generally composed of a housing, an electric motor, a cylinder block, a piston, control equipment (starter and thermal protector) and a cooling system. Cooling methods include oil cooling, air cooling and natural cooling. Linear compressors have no shaft, cylinder block, seal and heat dissipation structure. The compressor of general household refrigerator and air conditioner takes single-phase alternating current as the power source, their structure principle is basically the same, but the refrigerant that both use is different.
Danfoss compressor application range
1. The small
It is widely used in mobile applications.
Fully enclosed compressor with DC power supply.

2. The Large
Commercial air conditioning
Industry applications scroll compressors used in industrial applications

3. The other
Special types of compressors, such as high-efficiency compressors variable frequency compressors
compressors powered by solar energy.

Danfoss currently offers compressors for air conditioning and heat pump applications from 2.5-200 cold tons and compressors from 20W-20kW for refrigeration and refrigeration applications in the Chinese market.
The refrigerants used in compressors include all conventional HFC, HCFC and CFC refrigerants, as well as smaller compressors with temperature adjustment ranges from 5 degrees to 20 degrees (the difference between open and open temperatures) of 5 degrees to 20-27 degrees.
Heating: temperature controller fixed setting, 4 degrees heating. Additional functions and accessories for other temperature Settings and capillary length of 6.3mm or 4.8mm spacing can be provided upon request for a wider range of applications.
Danfoss compressor classification
Danfoss compressor variety is complete, can be roughly classified according to two cases.
1. Applicable to various refrigerants
Such as R22, R134a, R404A, R600a and R290.
2. Classify by application field
High evaporation temperature (5 degrees ±10 degrees) Medium evaporation temperature (-10 degrees ±10 degrees) low evaporation temperature (-25 degrees ±10 degrees)
Example: At present, the refrigerants used in cake display cabinets in China are mainly traditional R22 refrigerants and environmental protection R134a refrigerants. The evaporation temperature of refrigeration system is usually around -5 degrees to -10 degrees. This is a typical medium-temperature application.
Danfoss 'SC10D, SC12D and SC15D compressors using R22 refrigerant and the FR11G, SC10G, SC12G, SC15G, SC18G, SC21G and NL10MF compressors using R134a refrigerant can meet the requirements of this application.

Danfoss compressor SERIES

1.Danfoss SC series compressor
Danfoss SC series R134a refrigerant compressor is high and low evaporation temperature universal compressor, evaporation temperature from +15 degrees to about -30 degrees, a very wide range of applications. And in low evaporation temperature applications, can also operate in 220V, 60Hz power supply.
Danfoss SC series
Many refrigeration equipment manufacturers have noticed this characteristic of Danfoss compressors, and choose these 220V, 50HZ and 60HZ universal compressors when exporting products to Southeast Asia. This not only takes into account the excellent performance of Danfoss compressors, but also saves the equipment manufacturer a lot of work in preparing inventory and servicing. In addition, Danfoss compressors are designed for the ambient temperature of 43 degrees, working at comfortable indoor temperatures, danfoss compressors are more than capable of handling.
Danfoss compressor according to the starting mode is divided into high starting torque and low starting torque two ways. Also known as capacitor start (CSIR, CSR) and no 2.capacitor start (RSIR).
Capacitive start (CSIR, CSR) this way has a large start distance, and the motor efficiency can be improved in the CSR start mode, which will save more power in the operation process, of course, the cost also increases. RSIR is simple in structure and reliable in operation. But the starting current is large, suitable for the place with strong power supply.

3.Dc variable frequency scroll compressor
In December 2012, Danfoss second generation of commercial frequency conversion scroll compressor VZH series came out.
As a technology leader in hVAC solutions to environmental and energy challenges, addressing issues such as reduced energy consumption and precise temperature control, Danfoss has introduced the second generation of commercial variable frequency scroll compressors, the VZH series. With excellent design concept and excellent performance, this series won the American Refrigeration Expo Innovation Award.
The new generation OF VZH DC variable frequency scroll compressor has both inverter and compressor technology, which can be provided to customers as components and shorten the system development time for the whole machine manufacturers. Suitable for roofing machine, precision air conditioning, unit machine, process cooling and other applications, has unparalleled advantage in energy efficiency.
VZH compressor advantages
VZH compressor adopts efficient rare earth permanent magnet motor and stepless speed regulation controlled by frequency converter. The working efficiency of the motor is always higher than 92%, so it is more energy saving. At the same time, VZH gear pump selection, and equipped with a unique oil injection solenoid valve, to meet the low speed scroll seal required lubricating oil supply, control the HIGH speed OCR.
Compared with the constant speed compressor, the VZH compressor effectively reduces the noise during start-stop and partial load, and the night mode can be set to minimize the decibel during night operation.
For different national markets, the power supply frequency of compressors is divided into 50HZ and 60HZ. The voltage range of the compressor G series is 380V-480V, and the voltage range of the compressor J series is 200V-240V, meeting the power grid requirements of each country.
Currently, VZH can be connected in parallel. The oil balance problem in parallel connection is solved by oil level switch, oil balance pipe and current limiter. In addition, THE VZH compressor can greatly save the system cost. Taking the chiller as an example, compared with the constant speed compressor, it reduces the size of the system water tank, reduces the requirements on the system controller, simplifies the connection between the pipes, and reduces the complexity of the pipes.
