Air Conditioning Repair

The water chiller is used for a wide variety of purposes relating to cooling water quickly at a specified temperature.  In addition, these chillers help improve the quality of a product, making it possible for equipment to run more efficiently and effectively.  Typically, water is chilled by using a chiller, which is a quick and cost effective process, often seen used for cooling various types of equipment to helping with the molding process.

Today, high-tech and sophisticated chillers are available for cooling ozone generators, laser equipment, plastic vacuum pumps, welding machines, cutting equipment, x-ray machines, packing machines, printing equipment, and much more.  These chillers work by controlling water flow temperatures.  For instance, if a type of refrigerant is used, the water can be chilled to a temperature that can actually be adjusted within a heat exchanger.

While there are many refrigerant options, many people concerned with the environment are turning to solutions such as R-407c and R-134a gas, which is not only highly efficient but also environmentally friendly.  Developers of chillers who are making the equipment to help the environment include Doulton, Ultracool, Zarsky,and TrueTon, although there are many other developers of chillers that use refrigerants considered harmful.

When it comes to advantages of using a chiller, there are numerous things to consider such as:

• Low noise
• Low power consumption
• Motor protection for circuit breakers
• Antifreeze thermostat
• Level and flow switches

A chiller also comes in a variety of cooling capacities depending on the model. For instance, some will actually provide a cooling range of 0.7 to 470 kw.  As mentioned, there are many uses for chillers.  For instance, many are used to cool air.  Depending on the use, the design of the chiller would also vary.  In this case, the outside construction would likely be made from stainless steel.  These chillers also come in a huge selection of sizes with some so small they can fit nicely underneath a kitchen sink while others are quite large, being used for commercial reasons.

The price of a chiller has a wide range, which depends on the capacity, purpose, and model chosen.  A high efficiency unit that would be used for home purposes might cost only $500 to $1,000 whereas commercial chillers would cost into the thousands.  Regardless, chillers serve one purpose, which is to eliminate heat from liquid by using a type of vapor compression or absorption cycle.

For industrial or commercial uses, the chiller cools water and dehumidifies air for large industrial or institutional facilities.  These machines are highly precise in their function and again, for commercial use, they are expensive and cost a lot to operate.  Even so, they are a much needed piece of equipment and as long as they are maintained and cared for properly, they will last a long time.

When it comes to air conditioning, a chiller will use the chilled water to distribute out to coils, also known as heat exchangers.  Within the air handing unit, the used water is then returned to the chiller.  The coils take heat, both latent and sensible from the air within the chilled water, which is what creates the cooling capacity of the air conditioning unit.

Then for commercial uses, the cooled water is pumped through a type of laboratory equipment, which helps to keep machines, equipment, and even products at the necessary temperature.  As with molding and plastics, once melted, these materials have to be cooled at just the right temperature, which is what the chiller does.  The same would be true for any type of welding, metal working, die casting, formulation of pharmaceuticals, chemical processing, power supplies, and so on.

Without chillers, it would be impossible to process many of the things that people use on an everyday basis.  Within a commercial situation, chillers have multiple purposes, each with a set of advantages.  When looking at chillers, there are many types but five considered the most used.  These include:

• Scroll Compression
• Reciprocating Compression
• Screw-Driven Compression
• Centrifugal Compression
• Absorption

The first four types of chillers are types of mechanical machines, which means they are powered with gas turbines, electric motors, or steam.  The last type of chiller is run by a heat source, usually by combustion, hot water, or steam.  Regardless, chillers of all types and sizes are a huge part of the world in creating and maintaining important things we use.
