The primary function of an HVAC system is to provide thermal and acceptable indoor air quality. HVAC technologies can be categorized as heating, ventilation, and air conditioning. If you’re not sure what these systems do, here’s a brief introduction. These systems work to keep buildings, homes, and offices comfortable, and they can be found in a variety of settings. Some common types of HVAC systems of urdesign are residential air conditioners, commercial central air conditioning, and car heaters.
Air entering a building is sent through a specially-designed air inlet unit, and is then routed to different rooms and spaces. Depending on the system, air may be used for a variety of purposes, including removing dust and allergens, cooling and heating, and reducing humidity. This filtration process also allows the air to be moved to the appropriate places throughout a building, so that it can be used to achieve the desired temperatures.
The HVAC system also consists of several components. The outdoor unit includes a furnace, air blower, and evaporator coil. The indoor unit is typically located in a closet, basement, or attic. A control system uses a thermostat to set the temperature and humidity in the building. A compressor also controls the temperature of the indoor units and circulates refrigerant fluid throughout. The entire system can be controlled remotely with a computer, making it possible to monitor the temperature and humidity of a building.
The ventilation portion of the HVAC system includes the circulating fan and return and supply vents. The air filter is responsible for removing particles and preventing mold and mildew growth in the air. Ductwork and filters are also important components of the ventilation part of the HVAC system. While it may seem complicated, the workings of an HVAC system are often hidden. A single stage system, for example, will work even if there is no need for it.
The heating and cooling parts of an HVAC system may be separate and independent systems. These systems can be combined with the cooling and heating components of a hybrid HVAC system. A combination of both types of HVAC systems will have a variety of features. A hybrid HVAC system is a hybrid system where the heating and cooling components switch depending on the temperature. These are the most common types of HVAC systems. A home or office with a climate that changes drastically during the year will require a different type of HVAC system than a house in a colder climate.
During a school assembly, CO2 concentrations in the auditorium increase. Variable occupancy HVAC systems automatically respond to these conditions by increasing outside air volumes and reducing the amount of inside air when there is no need for the outside air. During school assemblies, the ambient CO2 levels in the auditorium are monitored and controlled using CO2 sensors. The variables of a hybrid HVAC system depend on how the building is configured and where the primary equipment is located.
