Air conditioning systems consist of compressors to change the refrigerant gas from a gas to liquid, and evaporators to remove the heat. Fans produce the cooled air by forcing air over the pipes that contain the cooled refrigerant. There have been many variants to Air Conditioning Systems systems, and this vary from individual room air conditioners, split units, central air conditioning systems and much more.
There is a high need for energy in all HVAC units and research is always in place to help to reduce the requirement of energy. Utility bills are often a major cost for households and need to be controlled. Starting currents are a major portion of power needed for air conditioners, that constantly switch on and off, as per thermostat settings. Technology has come up with variable speed motors that obviate the need for the intermittent working of compressors and this has led to a drastic reduction in power required. These motors can only run on direct current, instead of the alternating type that most utilities supply. These modified air conditioners have inbuilt inverters that convert the alternating current to direct current so that variable speed motors can be used.
Before any installation of HVAC equipment, it is needed to design it for the particular living space. It makes sense to conduct an energy audit of the home or property where such installation is required. This audit will judge the efficiency of the living areas to retain the temperatures that can come from the HVAC units. Doors and windows must seal correctly and not allow any leakage of air. Heat can also escape, or come in, through walls, roofs, and window glass. Walls and roofs can be insulated to reduce this loss or gain. Windows can have double glazing that is very effective in increasing insulation and reducing noise. Once this audit is done, corrective measures can be put in place.
It is also necessary to design the HVAC system so that it is tailored to the home or property. Room dimensions, ceiling heights can come into play and help to decide the likely load on the equipment. Location of the property and its orientation can also have an effect on HVAC design.
It is necessary that HVAC installations are carried out by professionals By http://sandiegohvacexperts.com who are knowledgeable and conversant with the equipment being installed. Maintenance of units is also a must and if done regularly it can greatly extend the life of the equipment, and prevent any need for repairs. Proper use and setting the right temperatures can play their own part in reducing running costs.
