Heating, Ventilation and Air- Conditioning System (HVAC)

HVAC is the acronym for Heating, Ventilation and Air-conditioning system. HVAC is a technological system used to achieve distribution of a balanced air-heat regulation in the environment. HVAC helps improve the quality of indoor air and helps in providing a relaxing atmosphere. This technology is built upon the principles of thermodynamics, fluid mechanics and heat transfer. Refrigeration is sometimes added to this system, where we might have something like HVAC&R OR HVACR. But what we commonly find is HVACR.

HVAC are used to provide and regulate heating and cooling services to buildings. With an HVAC system installed in a home, the ambient environment of a residential building or a commercial building and an industrial space is regulated. The indoor installation of HVAC system is not only done in residential buildings or commercial spaces. HVAC system can also be installed on ships and submarines, and in marine environments, where best building practices demands putting into consideration the peculiar temperature and humidity of water bodies or areas The ambient environment which includes the temperature, humidity, air flow and air filtering must be properly planned for as demanded by best practices in the construction industry. Requirement for standard practices in the construction of new buildings demand that an HVAC system be installed. An HVAC system is used to provide a relaxing and comfortable indoor atmosphere; the system is used to make available outdoor air that helps in diluting air from inside which have been contaminated with airborne contaminants such as odors from people within, volatile organic compounds (VOC’s) emitted from interior furnishings, chemical used for cleaning, and biological and synthetic airborne contaminants. . The indoor environment of buildings generally is therefore safe and healthy with the installation of HVAC system which uses fresh air from outdoors and escapes contaminated air from within through outward channels.

The HVAC industry grew from the inventions and discoveries made by tech giants Nikolay Lvov, Michael Faraday, Willis Carrier, Edwin Ruud, Reuben Trane, James Joule, William Rankine, Sadi Carnot, and a host of other inventors along this field. The HVAC industry started full blown at the same time with the industrial revolution. As the years passed by, new improvements were made upon this technology, higher efficiency and control of the system are being introduced by companies and inventors worldwide. The HVAC industry is a multi-dimensional enterprise, companies and individual experts can choose to specialize in the different levels of specialized industrial focus. The different levels of activities in the HVAC industry include operation and maintenance, system design and construction, equipment manufacturing and sales, also education and research to come up with novel ideas and improved innovation in the existing technology foe better performance according to industry standard.  There are several organisations that regulate and standardize the manufacturing and installation in buildings. Some are defined by country location while others have an international spread.  include American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), HARDI, SMACNA, ACCA. The International Standard Organisation (ISO) which has an international outlook is also involved in the regulatory and standardization process of the HVAC industry.

HVAC system categories that you need to know

The HVAC systems that we use both in our homes and industrially come in various types. The specific one to choose is dependent on the specific application for which it is required. Unfortunately, we often rush to make decisions on which type or category of HVAC system to purchase. This leads to ending up with a system that is not suited to our specific needs. Resulting in a waste of resources and dissatisfaction with the operation of the purchased system. This article outlines the major and important categories of HVAC systems and which ones are applicable for specific circumstances.
Single Stage HVAC systems
A single stage HVAC system can be simply described as an on and off heating or cooling system. There is only one possible temperature to which it can be set. This means that at every point in time for which a single stage HVAC is on, it is operates at its maximum energy output. This sort of system is useful for locations with extreme temperatures. Nordic countries for example that are prone to extreme cold will benefit from single stage cooling systems. Tropical countries in West Africa too with high exposure to heat from the sun will also find good use for single stage cooling systems. Another benefit of single stage HVAC systems is in non-human applications like cold rooms or providing cooling for instrumentation. Since these applications only require a fixed temperature, single stage HVAC systems will serve the purpose perfectly.
The drawback with this kind of system, however, is the fact that Energy consumption cannot easily be regulated except by turning off the system. Also, areas with the most extreme weather conditions often experience periods during which atmospheric conditions are temperate. A single stage HVAC system would not be easily regulated to suit the purposes of periods like this.
Multi-Stage HVAC systems
Multi-stage HVAC systems are just what the name implies- they have two or more heating or cooling levels. Most modern HVAC systems (including those connected to the Internet of Things) are multi-staged in design. This is not surprising. Multi-stage HVAC systems are more energy efficient since they do not have to operate at maximum capacity all the time, unlike single stage systems. Also, multistage HVAC systems can be modified to suit the comfort of the user. This is another reason why they’re more preferable than single stage systems.
Zoned HVAC Systems
Rather than heating the whole area within which they are installed, zoned HVAC systems are designed to be able to provide heating or cooling to specific areas of the building. This is achieved by the inclusion of valves which are able to either block or allow the flow of air to the desired areas. Zoned HVAC systems are also quite energy efficient. For example, they help to ensure that unoccupied areas within a building are not cooled or heated unnecessarily thereby reducing the overall energy expended. When incorporated with multi-stage design, Zoned HVAC systems provide very high energy efficiency. more info

Why you shouldn’t DIY HVAC Repairs

You could be one of those individuals who love trying their hand at most projects in your home, but it’s important to note that certain repairs and projects need experience and the technical know-how of a well-trained expert. Whether everyone in your home knows you for being pretty handy or you want to save money on your projects, DIY HVAC repairs is something you should never attempt. Of course, it normal for homeowners to take ownership of their homes and even want to handle all the repairs themselves. One of the reasons people want to attempt DIY repairs is to save money, but this usually ends up in more serious problems which require more cash. So, why should you avoid DIY HVAC repairs?

Safety Concerns

Attempting to deal with something you don’t know and understand will definitely result in injuries. Understand that HVAC units are highly technical and can it can be dangerous to handle them on your own. In fact, these systems usually use high-voltage electrical circuits which, when not handled with care, can result in serious injury. It’s obvious that you don’t have any experience or training dealing with electrical repairs which means you could disrupt the power service in your home or cause short-circuiting.

According to the Environmental Protection Agency, you’re supposed to have a specific certification before handling the chemicals which HVAC systems rely on to function. Don’t put your home and family at risk. Hire a well-trained, experienced professional to handle your HVAC installation or repairs.

HVAC work requires proper training and specialized Tools

As mentioned, HVAC work requires the right technical training and experience to get things right. Additionally, you cannot try building a chair without tools like a saw and a hammer. This is the same case when it comes to air conditioning companies. You need specialized tools so as to identify the problem before making the necessary repairs. The fact that you don’t have these tools means you shouldn’t risk causing more damage your HVAC unit.

HVAC replacement is Tricky

When dealing with HVAC units, it’s not just a matter of getting any unit and fixing it in your home. It’s important that your home gets a unit of the required size and capacity which is why you need a trained and experienced technician.

Small Problems could end up becoming Bigger HVAC problems

In most cases, a small issue could just be an indication of a bigger problem. You could end up causing more damage to something you thought you could handle. It’s, therefore, crucial that you hire a trained technician to help diagnose and fix the problem rather than attempting it yourself. It could end up becoming a costly, dangerous problem in the long run.

Voiding your Warranty

Well, it all depends on the HVAC system you have as well as its years of service. It’s important that you review the information on your warranty agreement to find out if there’s need for regular maintenance and repairs by a trained expert to ensure your warranty is not voided. You might repair small issues yourself only to realize you’ve ruined your chances of having major or rather larger repairs done at a lesser or no cost with your warranty. http://www.airconditionerclearwater.com/
