Ammonia EVR25 Series Refrigeration Solenoid Valve 2908g Weight 28-35mm Connection Size
Ammonia EVR25 Series Refrigeration Solenoid Valve in Automation Refrigeration System
The control technology, computer network technology and remote monitoring in the 21st century provide corresponding technical support and guarantee for the automatic control of the system, and also provide space for the automatic control of the ammonia refrigeration system. The problem of automation involves the development of electronic throttle valve for ammonia, the design of system circulation, the static and dynamic characteristics of refrigeration system. Efficient and energy-saving operation, safe use of refrigeration systems and safety protection, reduce production costs will bring new changes.Our Ammonia EVR25 Series Refrigeration Solenoid Valve 2908g Weight 28-35mm Connection Size will play an important role in this system.

Performance comparison between ammonia refrigerant (R717) and fluorine refrigerant (R22, R404A)
Safety: the explosive and toxicity of ammonia greatly limit its application. In recent years, the news about ammonia refrigeration system frequently appears, and people have some fears about ammonia refrigeration system. The high safety of fluorine refrigerant is the main reason for the rapid development of fluorine refrigeration system in recent years.
Environment: ammonia has zero ODP and zero GWP. R404A is an environment-friendly refrigerant, but its application will be limited by 2020 due to its poor environmental performance. At present, the industry is actively looking for a more environmentally friendly alternative refrigerant.
Material compatibility: when ammonia contains water, it is corrosive to copper. Therefore, copper and copper alloys cannot be used in pipelines and valves in ammonia systems, which limits the choice of materials for system equipment. Fluorine refrigerant has very high chemical stability and thermal stability, theoretically does not corrode all metals.
Water distribution: ammonia is allowed to be less than 0.2% water content, because ammonia is easily soluble in water, even if there is a small amount of water, there will not be freon "ice plug", so the ammonia system is dry to the piping system. The requirements are not as stringent as those of freon. Freon does not dissolve in water, so if there is water in the system, ice plugs are created. Usually we have a dry filter in the system.
Oil filling effect: at present, the lubricating oil of ammonia refrigeration system is mineral oil, which cannot be mixed with ammonia. Oil separators and oil collectors are usually installed, and lubricating oil is returned to the compressor through automatic or manual control.
