The difference between ammonia refrigeration system and fluorine refrigeration system

The difference between ammonia refrigeration system and fluorine refrigeration system

In the early stages of the development of the refrigeration and refrigeration industry, ammonia refrigeration systems have been widely used. With the development of the times, the shortcomings of ammonia systems have gradually been exposed, and they have been gradually replaced by freon refrigeration systems, and have been widely used in food processing, refrigeration and refrigeration. , Refrigeration logistics and other fields, today okmarts.com editor will analyze the difference between ammonia refrigeration system and fluorine refrigeration system.

1. Control comparison: Ammonia system needs to be set up with special personnel to operate, which cannot realize automatic operation, while fluorine system can realize remote automatic control, making the operation of the unit safer and more reliable. Not only that, the fluorine system can save nearly half of the electricity and operate more accurately. Thereby improving the quality of the product, reducing the cost of use, and ensuring safety.

2. Safety comparison: Ammonia is a toxic liquid, which will cause strong irritation to the human body. When the ammonia in the air reaches 0.6%, it will cause human body poisoning. When the concentration reaches 14%, it can cause combustion, and when it reaches 25%, it will Causes an explosion, threatening people’s lives and property; the Freon system uses environmentally friendly R22 and R404A refrigerants, which are colorless, odorless, non-flammable, and non-explosive, and can be used in various places, safe and stable, and eliminate In order to prevent the occurrence of the accident, the life safety of employees and surrounding people is effectively guaranteed.

3. Operation comparison: As the ammonia system is relatively backward, it consumes a lot of electricity during cooling, has a short use time, is prone to failure, and has many auxiliary equipment, and the unit is complicated. If one system fails, it will affect the operation of the entire unit. The effect is to reduce the efficiency of refrigeration; the system of the fluorine machine is relatively rigorous and the operation efficiency is high, which fundamentally reduces the power consumption, is not prone to failure, and ensures the stable operation.

4. Energy-saving comparison: Most ammonia systems use single-head compressors. The energy efficiency ratio of part load is lower than that of full load, especially when the load drops to 70%, the energy efficiency ratio drops more severely. Insoluble in lubricating oil, resulting in the formation of an oil layer on the surface of the pipe and evaporator, which reduces the heat exchange effect of the system; the Freon system uses PLC control, which has high accuracy and significant efficiency. On the other hand, Freon is soluble in lubricating oil, so it is opposite to the transmission. The image of the thermal effect is small, it can save half of the electricity than the ammonia system, and the energy saving effect is significant.

5. Civil construction investment comparison: the ammonia unit has a large structure and covers a large area. In addition to the unit, auxiliary equipment such as high-pressure liquid storage tanks and circulation barrels need to be installed. The total area is 5 times that of the fluorine system, while the Freon unit structure Compact, small footprint, so the requirements for the installation environment are relatively low, and the scope of application is wider.

6. Investment comparison: The ammonia system operates as a stand-alone unit. In order to avoid malfunctions and affect the use, it needs to be equipped with auxiliary equipment, and the unit uses a large amount of electricity, so the use cost is relatively high. Freon can realize automatic control, although the initial investment is relatively large Large, but no need for equipment crowding, low power consumption, long service life, and overall economy is significant.

　　 From the above point of view, the fluorine system has more obvious advantages compared with the ammonia system. In the future, the fluorine system will gradually occupy the refrigeration market and will be the mainstream of the development of the industry.
