The objective of HVAC are to control the temperature of air inside the designated “Air Conditioned space along with control of moisture, filtration of air and containment of air borne particles, supply of outside fresh air for control of oxygen and carbon dioxide levels in the air conditioned space, and finally control of the movement of air or. An HVAC controller receives information from sensors and sends signals to actuators.

It is often located in the mechanical equipment room (Figure 4). Figure shows a typical single zone DDC system. Pipe Fan Coil System , Chiller 5. HVAC stands for Heating, Ventilation, and Air Conditioning and is a complex branch of engineering.

In this article we learn HVAC for beginners along with the processes of Air Conditioning, comfort zone within a psychometric chart and a discussion about the need for comfort air engineering. Heating, Ventilation and Air Conditioning systems are tasked with circulating fresh air within living spaces, while maintaining the optimal temperature to keep the occupants comfortable. Maintaining an efficient, working HVAC system is paramount to keeping management smooth and providing thermal comfort. New VRV systems offer high levels of energy efficiency, as well as flexibility. They operate quietly and provide the user full control of the environmental temperatures.

On heat pump models there are two basic types of VRF systeheat pump systems and energy- recovery. These are also known as two-pipe systems. Choose from both rectangle and round configurations designed specifically for things like safety applications, low-leakage and heavy duty industrial needs, and backdraft for pressure relief.
