Learning The “Secrets” of HVAC

Role of the HVAC Systems

Indoor cooling and heating system in a building is a combined system of heating, ventilation and air conditioning usually abbreviated as a HVAC system. Heating, ventilation and air conditioning system are required to be combined for heating and cooling in a building. Purpose of installing the HVAC system is to ensure thermal comfort in a building as well as enhance the indoor air quality. The HVAC system can be used in both residential and commercial setting including apartments, hotels, single-family homes, and hospitals. Air quality and cooling is enhance by ventilating a building where outdoor air replaces indoor air. Ventilation ensures that there is cooling of the room as well as removal of odors, smoke, dust, heat, airborne bacteria and other gases that may accumulate in a room.

Air conditioning system are installed in rooms to enhance humidity and cooling of a building. The most appropriate buildings to install air conditioning systems is where windows are sealed to prevent disruption of the working of system. The disruption would hinder the proper working of the system hence inability to maintain indoor air conditions that are constant. In the heat exchange section, fresh air from outside gets in through a vent creating a positive air pressure. The vent also enhances removal of heat from the building using various processes including radiation, conduction and convention.

Systems used for high temperature heating provided either by electricity or combustion of fuel are referred to as a furnace. The furnace is used to supply heat into a living space through an intermediary distribution system in a building. The furnace can also function as a boiler which provides hot water that can be used for washing and bathing. Traditional furnaces used the passive air circulation system in the heating of a room. Warm air rises up to heat a room while cooler air sinks for reheating in a passive air circulation system. Recently, modern furnaces have been developed which depend on a fan that pulls cool air , reheats it and releases it into the environment for cooling the building.

HVAC systems in the air heating and air conditioning are beneficial for use in a building. The systems are energy efficient utilizing minimal amount of energy hence saving on the amount of power used and consequently lower cost of electricity. Comfort is key in buildings hence HVAC systems are essential in maintaining an appropriate temperature. It is also ensuring that the air in a building is cleaner free from odors, harmful gases and also harmful air-borne microorganisms. HVAC repair is also essential to ensure that it runs efficiently at all times to ensure proper air quality and temperature in a building. HVAC repair should be done by professionals who are specialized and have the right tools and equipment for repair and maintenance.
