An Introduction To Cooling Fans For Refrigeration
Cooling fans for refrigeration can be found in several different types of machines from large air conditioning systems to the refrigerators you use to keep your food cold in your own home. This article will discuss a few of the applications where these devices are typically to be found.
Cooling Fans For Refrigeration
The everyday wall or window mounted air conditioners are common devices that use cooling fans for refrigeration. Of course these aren’t the only types of air conditioners that make use of them as larger split systems and central units that utilize ductwork have them as well. This is true, because all of these units are basically like refrigerators without the use of an insulated box.
They all work on the same principle by evaporating a coolant such as Freon.
- The process begins with the Freon gas being compressed causing it to heat up.
- The heated Freon then passes through a set of coils which dissipates the heat and it turns into a liquid.
- It then passes through an expansion valve where it is evaporated and turns cold.
- The now cold gas runs through the coils which allow it to absorb the heat and cool down your home.
Industrial Fridges And Cooling Fans For Refrigeration
Industrial fridges are another example of the many modern inventions that use cooling fans for refrigeration. These devices are like large refrigerators that can store a large amount of food at a time. They typically can be walked into so it is easy to retrieve whatever you need when you need it. A freezer unit is usually built right in that is kept at 0 degrees Celsius so frozen foods can be stored safely, and is also typically used for wine cooling systems. These units have a defrost cycle, because ice will commonly build up on the evaporator. During this cycle a heating process is used to melt any frost that has built up over time.
Water Chillers
Water chillers are used to provide air conditioning to massive building structures where other methods such as window units and split systems will not be practical.
- They can also be used to lower the temperature of certain pieces of equipment like robot machines and computer parts.
- One of their main parts is the compressor which works in a very similar fashion to cooling fans for refrigeration.
- The coolant in these systems gathers up the heat and then removes it from the air.
- The evaporator sends the heat back into the atmosphere and the coolant goes back into the condenser where it is compressed into a liquid.
As you can see, there are many different uses for cooling fans for refrigeration and until now you probably took them for granted. They are a major part of the HVAC industry and without them we would be without a wide range of machines including those listed above as well as many others which are outside the scope of this articled to discuss.
