HVAC stands for heating, ventilation, and air conditioning. These systems provide the indoor climate control for both residential and commercial buildings. When it comes tothis, one size does not fit all. As a matter of fact HVAC systems can be quite complicate. calculating the right kind of system for your home or building is extremely important for the system to heat and cool effectively and to be energy efficient in addition.
HVAC systems come in many types and applications. They are classified as either central or local. The central air conditioning and heating system provides the necessary heating and cooling and ventilation from a central location in the building such as from a boiler or furnace. It works by circulating heated water or steam by piping or ductwork to unprotected to heating and cooling.
Central air conditioning units use a compressor and a condenser unit that uses a refrigerant or coolant such as Freon. The refrigerant is circulated by copper tubing. The refrigerant absorbs the heat, turns to vapor, travels to the compressor, and moves to the outdoor wire where the heat is forced out. Then the refrigerant passes by a device where it is converted to a low pressure, low temperature liquid and returned to the indoor wire. The cool air is then circulated by the ductwork to provide cooling for the structure.
Local HVAC systems are devices that provide heating and cooling to immediate areas or rooms. They do not circulate throughout complete structures. Local HVAC systems may include wood or pellet stoves, window air conditioners, and space heaters. Electric baseboards are also considered to be local HVAC systems if the unit is installed into a single area.
calculating which HVAC system is right for you and your needs should be determined by an HVAC specialized in order for you to get the maximum benefits from the system. A qualified and certified HVAC contractor will determine the kind unit that is best for you and will install the unit in the proper place so that it will meet your cooling and heating requirements.
