Understanding Charlotte HVAC systems

July 8, 2014by Sophie The Dog

Charlotte HVACHVAC systems are known as one of the best inventions of our time. These systems have provided us with comfortable living environments by eliminating excessive humidity and offering an improved inside atmosphere. These systems transfer clean air into our homes and businesses regardless of what the weather may be outside.

HVAC stands for heating, ventilation and air conditioning. HVAC equipment creates a comfortable environment by either decreasing or increasing the temperature and controlling the humidity level. These systems help in improving the indoor air quality by supplying access to fresh air and removing all airborne and odor contaminants.

System designs for HVAC are based on the laws of thermodynamics, heat transfer and fluid mechanics. Even though the operation of this unit may seem complex from inside the home, its functioning is really quite simple. There are three essential components of all HVAC and weather control systems: warm or cool air source, a system regulator, and channels to distribute the warm or cool air to different rooms. An indoor coil comprises the unit with several tubes that increase the refrigerant temperature. The liquid used as a heat transferring agent in the unit depends entirely on the system. While the tubes in the indoor coils increase the cold surface area, the temperature between the liquid passed through the coil and the air passed over the coil increases as well.

Once the refrigerant passes through the outside coil, it condenses and loses its heat while also maintaining a higher temperature and pressure. Through a cooper tube located in the fan unit, this refrigerant liquid is transferred to the evaporator coil. The refrigerant is converted into low pressurized gas that expands and absorbs the heat from the air inside your home through the duct system. This leaves cool air behind for distribution. The same cycle continues each time you switch on your Charlotte HVAC system for air conditioning.

Contrarily, when you need it to heat your home, the process gets reversed. The system absorbs the heat from the outside air and pumps it to the evaporator coil for distribution inside your house or office. While these systems push out warm or cool air, they also remove excess humidity. The extra moisture in the air is transported to the outside coil in the unit and then transferred to a drain. Used in industrial, corporate and residential environments, air conditioning HVAC systems assist in regulating temperature while promoting a healthy environment.
