When you choose a career in HVAC repair, you have a wealth of knowledge to learn before you are ready to jump into the field. Someday you will be able to enter a home and solve a radiator problem or air conditioning malfunction, but before that happens you must internalize information regarding the three most important areas of HVAC repair information. These areas include heat transfer, thermodynamics, and fluid mechanics.
Although these HVAC repair terms may seem daunting now, they should pose no more of an intimidation than any other unknown vocabulary. Once these definitions have been explained and demonstrated, they will simply become descriptions of well-understood procedures.
It has been said that the very best place to start is the beginning. Heat transfer encapsulates the heart of HVAC repair, and so it is fitting to consider this procedure the beginning of the journey. The process of heat transfer occurs naturally in nature, and can be reproduced by people in order to control temperatures of certain environments. In HVAC repair, you will encounter various types of heat transfer. These types of heat transfer include radiation, heat convection, and heat conduction.
The next stop on the journey to becoming an HVAC repair technician will familiarize you with the world of thermodynamics. Basically, thermodynamics is the science behind heat transfer, and therefore, HVAC repair. It is important to understand thermodynamics so that the principles behind a working heating or cooling system do not remain a mystery. If the study of thermodynamics particularly appeals to you, then you can reach beyond HVAC repair and become the thermodynamics engineer who develops the heating and cooling systems of the future.
Finally it will be time to focus on fluid mechanics. When studying fluid mechanics, an HVAC repair student will begin to understand the way that various forces affect fluids such as liquids, plasmas, and gases. Fluid mechanics includes the areas of fluid motion, fluids at rest, fluid dynamics, and fluid kinematics. Because fluids play an integral role in HVAC repair, it is crucial to understand basic elements about them.
Although all of this information may seem overwhelming, it is simply a matter of spending some time figuring out what it is all about. Before you know it, you will be the one to save the day when the mall’s air conditioning system breaks. HVAC repair can be a very demanding job, one that interrupts your sleep, your vacations, and your holidays. However, the service that you will be providing to others makes it all worthwhile.

Process Chillers
A process chiller is a device that provides a cooling system that can be useful in many different organizations. This type of unit is basically a cooling system that uses a liquid to absorb heat first and after that is goes through a cooling process to get rid of the heat that is present.
Process chillers are used in different workplaces and in different devices such as refrigeration and air conditioning. If you think about how your refrigerator or air conditioner works, it makes all of the heat in your house or removes all of the heat from your food and cools it.
The process occurs with heat being removed with an absorption refrigeration sequence or a vapor compression technology piece. To create a coolant, it is possible that you can use plain water in the different portions of process chillers; a glycol based mixture is more common to use. If both are not available, you may also use a corrosion inhibitor to get the job done.
The unit is more used in air conditioning than any other device. Within the air conditioner, there are a series of different coils throughout the system. In that system of coils, your coolant – whether it be water or another type of coolant absorbs the heat as well as releases it in a cycle that lasts until the temperature that is needed is reached.
Many different factories and industries are known to use the process chillers device. For example, a plastics industry, or metal work, welding, food processing, and HVAC industries use process chillers. In addition to all of these industries, a main and important workplace uses a process chiller, a hospital. A hospital uses a process chiller because it is necessary to keep the MRI machines and lasers at the correct temperature for it to work correctly.
Many different industries use centralized or decentralized chillers. A centralized chiller can handle more than one machine and a decentralized chiller can handle the control of a separate machine.
Be sure to consider certain things when you are researching a process chiller. The price of purchase and total cost of operation, the capacity of the chiller’s cooling, the type of evaporator, the material of the evaporator, types and materials of the compressor, and the different specifications of the process pumps. The different specification can be listed as pressure, flow, and the pump material.
To save more money be sure to look at which chiller is environmentally safe and is the best for your uses.

Chillers and the People They Work For
A chiller can be incredibly common and may seem quite simple as well. Sometimes a chiller keeps your food fresh, like a refrigerator or freezer. Other times a chiller keeps your house at a reasonably comfortable temperature, like an air conditioner. A chiller may be hiding in a place that you least expect to find it. For example, many DVD players and laptops harbor a tiny little chiller that keeps the little motor running smoothly. On our end of the deal, a chiller makes life convenient and comfortable, and all we have to do is plug in the cord and pay the electric bill. However, a chiller can be much more serious and complex for the people whose lives depend on it functioning properly.
While most people use a chiller in the form of a refrigerator in order to keep food fresh and safe, some people need a chiller to keep food and drugs at very specific temperatures. In the food processing industry, a chiller must keep foods at certain temperatures during the preparation period, then at a different temperature for the packing stage, and then at another temperature for the shipment and storage stage. If a chiller malfunctions anywhere along the way, the food could be spoiled or develop colonies of bacteria. Every time there is a recall for an outbreak of salmonella, the situation might have been prevented with a properly functioning chiller.
Prescription drugs can be very tricky to work with as well. During the processing stage, certain ingredients must be mixed together at specific temperatures, and developers rely on a chiller for these steps. If the ingredients are mixed together at a temperature that is too low, then the ingredients will not homogenize thoroughly. If the ingredients are mixed together at a temperature that is too high, some of the active cultures and bacteria could be killed. It would be very dangerous for people to receive medications that have lost their healing power. People who take heart medications, or blood thinning medications, or even anti-psychotic prescriptions place their lives in the hands of the drug companies.
In some cases, a chiller is used in a very common way, but the results of a malfunction or technical failure could be disastrous. Think about hospitals and nursing homes, especially the ones that are many stories high. People who reside in these facilities often do not have the strength or capability of resisting high temperatures. Small summer heat waves could fatally injure these people who depend upon the staff at the facility to take care of their health. If the chiller that provides temperature control in the building were to falter, the end result could be tragic.

It's not IF you have a dryer fire.....It's WHEN!
Don't become a statistic!
The above statement used to be a scare tactic, until we researched our nations 15,500 clothes dryer fire statistics. With 10 deaths, 310 injuries and $84.4 million in property damage in 2006 alone, they’re troubling! Just as troubling, at least 28% of these fires are caused by “lack of proper maintenance.” Read More >>
