HVAC stands for heating, ventilation and air conditioner and it is a kind of technology that assists you in under roof thermal relief and control indoor humidity and air flow. HVAC works in a dual aspect because the temperature can be raised and lowered. It takes care of proper filtration and air movement. It contains a small AC inside which during summer convert warm air into the cold. It also works as a heating device in winter and converts cold air into warm. In short, irrespective of the temperature outside it maintains your indoor comfort throughout the year. It can be used at temperature-sensitive commercial & industrial areas, at malls and hospitals as well.
Heating and cooling requirements vary with nature. In winter your body needs a higher temperature to keep it warmer than outside. During the summer your body requires less temperature to stay cool. In order to fulfill these requirements, you need an efficient HVAC system installed at home. Before purchasing it, you must keep in mind your home comfort system. You will not take this decision repeatedly in your life because it requires an investment. Indeed, selecting the right option can be a hectic task. According to www.mytrustedcontractor.com you need consulting services of heating and air conditioning contractors. Technology, which is efficient and consistent with comfort should be installed. Old HVAC, were less efficient and were not environment-friendly. A perfect HVAC system must have properly programmed thermostat, well-sealed ductwork, and ample insulation.
Before buying a new or upgrading your HVAC system, you need to consider the following points.
Nowadays, we are polluting our surroundings by using the technologies that appear to be useful and beneficial but in reality, they are causing damage to our environment a lot that we can’t even imagine. Our environment needs to be conserved and safe. The technologies we are utilizing are affecting our habitat badly. One form of such pollutant is Chlorofluorocarbons which is disturbing our eco by depletion of the ozone layer. As a result, the harmful infrared rays and ultraviolet rays are doing harm to us in the form of various severe diseases like Skin cancer and solar elastosis, etc. We must upgrade our HVAC system which should be eco-friendly and doesn’t produce such chemicals that are injurious to our health. Nowadays upgraded HVAC system releases chemicals i.e. R-410A which is less damaging.
As we are living in a universe where dearness is increasing constantly. Everyone prefers to purchase essentials at a low cost. In this case, if you are upgrading your HVAC system, always take notice of which form of energy (that can be used to operate this system) is less expensive, for example gas and electricity. If electricity rates are cheap, you should move to heat pumps that not only provide warmth to your homes in winters but also keeps your surrounding temperature balanced in summers as well. And if in case gas is less costly, you should switch to gas.
While upgrading your HVAC, the efficiency of the system should be your foremost priority. This system ingests a remarkable amount of energy. So, if we make it more efficient it will use less amount of energy and ultimately becomes economical. To check heating efficiency, we can use Annual Fuel Utilization Efficiency, the greater it is, the greater will be the system’s efficiency. And cooling efficiency can be analyzed by the Seasonal Energy Efficiency Ratio, the higher it is, the higher will be the efficiency of the air-cooling system.
Noisy furnace or air conditioner is more than just annoying. It basically indicates the failure of any operation. Different sounds have ultimately different causes and results. For instance, a blower fan can produce some grinding noises if it scrapes opposite to any other metal. Or the shaking of the motor may occur due to loose mounting bolts. And it also produces some crazy operating noises. So, while upgrading its noise level should be checked in decibels (db.) and the noise level of the upgraded system should be under 60 db. approximately.
In a nutshell, HVAC is a vast unit concerned with many applications ranging from comfort air conditioning, process cooling, industrial cooling, datacenter cooling, pharmaceutical process and manufacturing center of medicines or drugs. It is a sub-discipline of mechanical engineering which has its concepts and application based on thermodynamics, heat transfer and fluid mechanism. Its most common application is comfort. It is concerned with maintaining indoor temperature and moisture content of the air in such a way that the occupants in the room can feel comfortable and this condition is maintained by fixing a specific temperature of the air at a specific moisture content.
