HVAC basically stands for heating, ventilation, and air conditioning and it is a technology that focuses on ensuring vehicular and indoor environmental comfort. The main aim of HVAC systems is to make sure that there is a thermal comfort for various spaces occupants. HVAC systems tend to be applicable in various spaces including schools, homes, offices, hospitals, hotels, vehicles industries or any other places where human may be living or spending time. The HVAC focus on providing the right levels of temperature and humidity and at the same time ensure fresh air circulation in the space in question. Ventilation tends to involve replacement of air even as it also focuses on ensuring temperature control, removal of moisture, replenishment of oxygen, removal of heat, smoke, odors, carbon dioxide, airborne bacteria and other gases.
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. The central heating system tends to be responsible for the heating and may involve boilers, furnaces, heat pump among other critical 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. In most cases, electricity source tends to be an alternative or a backup 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 know that incomplete combustion can be hazardous especially to the house occupants. Incomplete combustion, for example, tends to lead to a health hazard. For one to avoid instances where he or she ends up with impure air, it would be essential to work with the best HVAC technicians.
Dpending on the HVAC in question, it would be possible to have free cooling. Dehumidification is yet another aspect of the HVAC you need to know about. Most HVAC systems tend to get any moisture back to the liquid form before it gets into the living space. The vapor is collected as water and piped out of the house. The main aim of dehumidification is to make sure that the moisture levels in the house are not too high. 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. It is essential for one to know when he or she should check the filters.
