Heating, ventilation and air conditioning are the more refined concerns for the construction and maintenance agencies these days. HVAC Companies are dedicated to the cause of providing people with better and more economic solutions in this regard. Specialization and continuous researches in engineering help these companies in their endeavor. Let’s peep into the issue more closely. Heating The need to heat up a room or many rooms has been a concern particularly with the regions of cold climates. There are heaters, boilers to perform this. But modern way to heat the living or working area has improved a lot. The researches and improvements have been on diverse lines including use of warm air to heat up the room. Even water has been used for the purpose. The benefit of using warm air is that the same path of airflow can in summers be used by the air conditioning equipment to cool the room or area. The path for the air is in the form of ducts and it is called ductwork. Ventilation You know that suffocation is the result of improper ventilation. One may or may not feel the lack of proper ventilation or one may get habitual to the improper ventilation; it is all the more harmful for the health and efficiency of the people working in such environments. Like any of the construction agencies that have to take care of the individuals who reside or work in a particular space within the room while working out the exact minimal ventilation arrangement. The comfort of a place is widely decided by its ventilation. It has in turn to do with temperature regulation, the humidity of a place. Lack of it may result in a humid and infectious environment with lots of bacteria and fungi present in the space and the walls, cupboards etc. It is more important for the big buildings, each and every section of which cannot be relied upon the natural air flow for ventilation. Hence the force mechanical ventilation is to be applied. A condition is still dangerous when the building as whole exchanges enough air from exterior but the air is not circulated uniformly inside the buildings. Inner sections of the building may remain suffocated in such situation. To unite the ventilation concerns with the heating/cooling concerns is what is done with a good HVAC system. Air Conditioning Air conditioning means to remove the heat to keep the room cool. Air, water, various chemicals and ice are all used for the purpose of refrigeration. They are used as conductors or mediums of heat transfer. Air conditioners mostly regulate temperature ventilation and humidity. There is a cycle involved in the process of refrigeration. The cycle can be divided into four parts to have an understanding of it. The medium is in its gaseous state in the first part of the cycle. This is at a high temperature and pressure when it performs its heat transferring action. It emits energy to outside of the building. Due to this loss of heat it converts into liquid. The liquid is again allowed to pass through the sections of the machine inside the room. This circulation helps in cooling as the liquid is cool now. The regulation of temperature is by way of regulating the amount of the liquid to circulate. As the liquid circulates making the surroundings cool it gets warmed up. And the process is repeated again and again. Efficiency and economy In the overall system of HVAC that unites all above aspects, efficiency of the system is most important. Efficiency is measured in terms of the high effect at lower expense of electricity or other source of energy. It in turn results in economy of the system.
