Industrial Refrigeration Systems How It Works

The ammonia gas condenses into ammonia liquid dark blue at high pressure.

Industrial refrigeration systems how it works. The coils on the back of the refrigerator let the hot ammonia gas dissipate its heat. Here are some basics on how industrial refrigeration systems function. The high pressure ammonia liquid flows through the expansion valve you can think of the expansion valve as a small hole. The compressor compresses the ammonia gas.

Modern vapor compression systems for comfort cooling and industrial refrigeration use one of several types of compressors. In this video were going to be looking at industrial refrigeration system basics with a focus on ammonia refrigeration systems we ll start at the basics and work our way up covering some typical systems for single stage two stage as well as cascade systems to help you learn the basics of industrial refrigeration. In order to experience cold you have to remove the heat from something and this is the basic principle behind all refrigeration systems. How a refrigeration system works.

This is the part of the refrigeration system that is doing the actual cooling. The compressed gas heats up as it is pressurized orange. Regardless of the type of refrigerant used refrigeration systems use several different devices including a condenser compressor evaporator and expansion device throughout the entire process. Industrial refrigeration system basics in this video we ll be looking at how ammonia refrigeration systems work starting at the basics to understand how in.

Refrigerant grade anhydrous ammonia is a clear colorless gas or liquid and about 99 95 pure. In some systems the compressor is driven by an external motor called open drive or open drive system. The purity of the anhydrous ammonia is vital to the properties that make it a good refrigerant. Ammonia refrigeration works much like industrial refrigeration systems using synthetic refrigerants with the major exception being that it uses anhydrous ammonia as the refrigerant.

Because its function is to absorb heat into the refrigeration system from where you don t want it the evaporator is placed in the area to be cooled the refrigerant is let into and measured by a flow control device and eventually released to the compressor. Some people believe cooling systems create cold air but this is not technically the case.
