There are different types of chillers available in the market today but you should be aware to know which is best for yourself. Industrial chillers are classified as a refrigeration system that cools a process fluid or dehumidifies air in commercial and industrial facilities. A chiller will use either a vapor compression or absorption cycle to cool. Chilled water has a variety of applications from space cooling to process uses. Let's dive into the article to know more about different types of chiller-

types of Industrial Chillers

A chiller is rated between one to 1000 tons of cooling energy.  There are three different types of chillers:

•  air

• water 

• evaporative condensed chillers. 

There are four subcategories in each of the above categories for industrial chillers:

•  reciprocating,

• centrifugal,

• screw driven

•  And absorption chillers.

 The first three types are mechanical chillers which are powered by electric motors, steam, or gas turbines.  An absorption chiller is powered by a heat source such as steam and uses no moving parts. 

Components of an Industrial Chiller

The mechanical compression cycle has four basic components through which the refrigerant passes: (1) the evaporator (2) the compressor (3) the condenser (4) the expansion valve.  The evaporator in the chiller will operate at a lower pressure and lower temperature than the condenser.

How an Industrial Chiller Works:

In an ideal cycle, the condenser serves as a two fold component.  Before any condensation occurs, the high pressure vapor must be first brought to a saturated condition (de-superheated).  Enough heat must be transferred from the refrigerant to lower its temperature to the saturation temperature.  At this point, condensation can begin.  As heat continues to be transferred from the refrigerant vapor to the air (or water, if a water condenser is used), the quality of the refrigerant (% of the refrigerant in the vapor state) will continue to decrease, until the refrigerant has been completely condensed.  In the ideal system, this occurs at the outlet of the condenser.  

So, in order to reduce the temperature, the pressure has to be reduced, and some sort of restriction is required for this to occur.  It would be preferable if the restriction could regulate itself as the system load demands change.  This is exactly what the thermostatic expansion valve does; it is an adjustable restriction which causes a reduction in liquid refrigerant pressure, yet will modulate in an effort to maintain constant superheat at the evaporator outlet. 

Our ideal cycle has experienced a pressure drop in the thermostatic expansion valve.  Sub cooling or superheat cannot exist where there is a mixture of liquid and vapor.  Therefore any place in the system where the refrigerant exists in two states, it will be at the saturation temperature for its pressure.

Some of the liquid refrigerant is required to boil as a means of removing the heat necessary to achieve this lower temperature.  Yet another heat transfer process, which yields a lower liquid temperature.  The liquid that is sacrificed in the boiling process explains the increase in refrigerant quality.  The greater the difference between the liquid temperature and evaporator temperature, the more liquid will have to be boiled in order to achieve the new saturation temperature.  This results in an even higher refrigerant quality.

Evaporators in Industrial Chillers

Shell & Tube Evaporators:  Typically configured with the refrigerant flowing through the tube side and the process fluid through the shell side of the unit.  Tube construction can be copper, cupronickel, or stainless steel.  Shell construction can be cast iron, brass, cupronickel, or stainless steel.  This style of evaporator has lower pressure drops than Brazed Plate technology and is available up to 500 tons in standard construction.

A central air conditioner costsminimal as compared to the features it offers the most convenient and cost-effective way to cool and dehumidify your entire home. Individually, it costs more than a room AC or an evaporative cooler, but its price can be less than that of multiple, smaller units combined. If you already have existing ductwork, expect to pay a lower installation cost. The strategic location of vents allows it to cool areas more evenly.

Benefits Of Central Air

Installing central air has many benefits and few drawbacks. For some people, the cost of central air can be prohibitive, but financing is usually available. Here are just a few important benefits of central air systems:

CENTRAL AIR SYSTEMS OFFER MANY SPACE SAVING OPTIONS

You have a choice from among hundreds of different models of central air systems. You will be able to find one that suits your lifestyle and that fits into the space of your home. For example, if you live in an older home that does not already have ductwork or the space to install it, you can get a central air conditioning system that does not require ductwork. With a ductless system, you will not be forced to give up square footage to accommodate new ductwork. Moreover, you won’t have the expense of installing it. These ductless air conditioning systems are a great choice if your home cannot accommodate ductwork easily.

If you want to replace a furnace and install a new air conditioning system at the same time, you can opt for a system that combines a central heating system and a central air system in one cabinet that is all housed outdoors. These packaged systems are another way to save space because they eliminate the need for a separate furnace indoors.

It provides cleaner air for your home 

Your central air conditioning system circulates air by pulling it out of the rooms in your house through the return air ducts. During this process, the air is pulled through an air filter. Depending on the density of the filter, the filter removes airborne particles such as dust, lint, pet dander, and allergens. Some filters are designed to remove microscopic allergens and other pollutants. The filtered air is then routed to air supply ductwork that carries it back to the rooms. Especially for people with impaired or sensitive respiratory systems, a central air conditioning system can contribute to better health. This gadget will reduce the number of pollutants that get circulated through your system and into your home. Not only does the GPS kill the mold and bacteria floating in the air, but it also eliminates odors. 

Low maintenance and reduced cost 

The new systems require very little maintenance. With a simple annual inspection and routine service, your new central air system should operate at optimal levels for many years. Get a service contract with a professional HVAC technician to have your system tuned up each year before the warm season starts. Think of annual maintenance like a tune-up for your car. It will keep the components clean, lubricated, and working properly. If it needs minor repairs or replacement parts, you can take care of it before it becomes a major issue.

Adding a central air conditioning system can make your home more competitive with other homes on the market. Central air will add to the desirability of your home. It is an investment that will add immediate value and hold its value over the longer term.
