Product Description

1'' Ammonia EVRA 25 Refrigeration Solenoid Valve

Ammonia refrigeration Whether it is a single-stage compression or a two-stage compression system, to achieve complete and complete automation, it has an important premise, that is, to simplify and improve the traditional refrigeration process scientifically. Only in this way can automation be easier, safer and more reliable. The most important component inside is the refrigeration solenoid valve. Our EVRA 25 ammonia refrigeration solenoid valve is used in ammonia refrigeration automation system.

Refrigeration Unit part (EVRA 25 Cast Iron Refrigeration Valve)

What's the difference between the fluorine refrigeration, ammonia refrigeration? The following is a detailed analysis of ammonia refrigeration system and fluorine refrigeration system similarities and differences.

One-time investment:
In general, large and medium-sized ammonia refrigeration system investment than the same scale of fluorine refrigeration system is less. This is mainly because the refrigeration units, equipment, pipes, valves and other components of the fluorine refrigeration system are expensive, and the fluorine refrigeration system has a high degree of automation and relatively high investment.

Operating cost:
Ammonia refrigeration system has low working temperature, large refrigerating capacity, low energy consumption and low operating cost.

The refrigerant of fluorine refrigeration system has higher quality, smaller unit refrigerating capacity, higher energy consumption and higher operation cost.

Environmental characteristics:
Ammonia in the ammonia refrigeration system is a natural working substance. The ozone consumption coefficient ODP = 0, and the global warming coefficient GWP = 0. It has no pollution to the environment. Due to the destruction of the ozone layer, freon refrigerants in CFCS have been eliminated.

HCFCs has a smaller ODP and a smaller GWP on the earth, which has a certain destructive effect on the environment. Under international agreements, developing countries can use them by 2040.

When ammonia reaches 16 to 25 percent in the air, it can explode if exposed to open flames. Ammonia is toxic and can cause asphyxiation and frostbite. Poor security. Large capacity ammonia refrigeration systems should not be used in densely populated areas. F-22 is non-toxic, mixed with air, does not explode, and has good safety.

In densely populated areas (developing countries), f-22 systems and f-134a systems are more secure. Of course, if conditions permit, the application of CO2 refrigeration system is more environmentally friendly and safe.

Supply and return:
Ammonia system is usually connected with evaporator by bottom in and bottom out. Fluorine system is generally connected with evaporator by up and down connection to facilitate oil return.

Horizontal suction pipe of ammonia system should be inclined to circulating cylinder or gas-liquid separator; The horizontal suction pipe of the fluorine system should be inclined to the compressor.

Liquid supply method:
Ammonia system and fluorine system can supply liquid directly, liquid pump and gravity liquid to evaporator.

Ammonia and fluorine are medium temperature refrigerants with moderate pressure and temperature, suitable for refrigeration, refrigeration, air conditioning, industrial refrigeration, beer, pharmaceutical and other industries.

Fluorine systems are safer for direct evaporation air conditioning systems. The ammonia system can be air-conditioned by indirect cooling "superbrine".

Degree of automation control:
Fluorine refrigeration system automation, generally do not need manual operation, saving labor costs.

Ammonia refrigeration system mainly manual, low degree of automation, but good stability.

Solubility of oil:
The solubility of ammonia and oil is small, and the surface of ammonia Heat Exchanger is easy to form oil film, which affects heat transfer. Therefore, evaporator, condenser, accumulator, intercooler and oil ammonia separator should be drained regularly.

In the fluorine system, fluorine and oil dissolve each other, and the oil film does not form an oil film on the surface of the heat exchanger and does not affect heat transfer, but the excessive oil in the evaporator makes the evaporation temperature rise.

Fluorine system is generally equipped with automatic oil return device. The piping design and installation of the fluorine system shall be considered when setting the oil return elbow. Oil balance should be considered in parallel units.

After years of design, installation and operation management, the ammonia refrigeration system is mature and stable.

Due to the irregular design, installation and operation management of the fluorine refrigeration system, coupled with the quality of the self-control components, despite the high degree of automation, the operational stability still needs to be improved, which is prone to burn-in accidents.
