HVAC involves heating, ventilation, as well as air conditioning both in houses as well as in vehicles. The main aim of HVAC systems is to make sure that there is a thermal comfort for various spaces occupants. Among the places where HVAC systems may be applicable include in homes, hospitals, vehicles, ships, submarines, offices, schools, among other spaces. HVAC systems also tend to focus on ensuring the right temperature, fresh air circulation and also ensure the right humidity. Even as the HVAC system focus on ensuring the right temperature, it also need to make sure that the air in the area in question is clean of smoke, carbon dioxide, odors, airborne bacteria among other impurities.
The ventilation tends to focus on ensuring the right temperatures and at the same time ensure replacement of new air from the outside. Heating on the other end tends to aim at keeping the building or the vehicle warm. When it comes to houses, the heating system tends to involve the central heating system which tends to come with systems such as furnaces, boilers, heat pump to heat water among other heating aspects. One would also need to know that that the sources of energy tends to range from solid sources, liquid sources as well as gases. However, electricity may be yet another source of heat. For heat to be distributed throughout the house, there tends to be a need to use water or even steam.
One would need to note that uses of space heaters, furnaces, and boilers demand proper installation and also ensure proper and regular repairs bearing in mind that incomplete combustion can lead to emission of carbon monoxide, nitrogen oxides, volatile organic compounds, formaldehyde among other combustion byproducts. Incomplete combustion, for example, tends to lead to a health hazard. One would need to consider working with the best HVAC technician to avoid instances where he or she ends up having impure air in the interior space.
HVAC also tends to involve free cooling which tends to have high efficiencies. Dehumidification is yet another aspect of the HVAC you need to know about. One would need to know that the evaporator tends to operate at a temperature below the dew point making the moisture to condense on the coil tube. The vapor is collected as water and piped out of the house. The dehumidifying aspect of HVAC tends to focus on controlling of humidity in a building or a room. Basements with higher relative humidity would need to be installed with a dehumidifier. One would need to know that dust tends to build over time and hence the need to make sure that filters are always cleaned. Homes with furry pets or even dusty environment would need to consider checking their gauze more often.
