HVAC System Components & How You System Works

An HVAC system is simply a collection of special HVAC components working together to move heat to where it is wanted (the conditioned space) or to remove heat from where it is not wanted (the conditioned space) and put it where it is unobjectionable (the outside air).

HVAC System Components

The basic components in a common central commercial HVAC system as illustrated are:

HVAC DiagramFan(s) circulate the supply air (SA) and return air (RA).

Supply air ductwork moves the air from the supply fan to the environment space.
Air devices like the air outlets send return air inlets.

The ductwork moves the air flows back from the environment space to the mixed air chamber.
The outside air (OA) device allow for the entrance of outside air into the mixed air chamber.
Filter section(s) remove dirt and dust particles.

Depending on the type of heat exchanger (hot water coil(s), steam coil(s), refrigerant evaporator, or chilled water coils) add heat to or to remove heat from the circulated air.

Some systems use auxiliary heating devices such as natural gas furnace(s) or electric heating element(s).

The compressors function is to compress the refrigerant vapor and pump the refrigerant around the system.

Your condenser, remove heat from the refrigerant vapor and then condense it to a liquid.
Fan(s) circulate the outside air across air-cooled condensers.

Some central systems use water or steam boiler(s) as the heating source, but some central systems use water chiller(s) as their central cooling source.

Many system controls are used to start, stop, or regulate the flow of air, water, steam, refrigerant and electricity.

The Types of Heat Transfers Methods

The three types of heat transfer are conduction, radiation, and convection. When your hand touches a cold wall, this is an example of heat transfer by conduction. A glowing red-hot portable electric heater is an example of heat transfer by radiation.

When air is heated, it rises; this method is called "natural" convection. "If a fan or pump is used, this is called Forced" convection.

HVAC System Example

Deciding on the size of your HVAC system is calculated based on the heating, cooling and ventilation loads. The air volumes are in units of cubic feet per minute (cfm).

As an example, if the total volume of air supplied to the environmentally controlled space is 6,000 cfm. Of this 6,000 cfm circulated through the space and back to the air handling unit (AHU), 1,000 cfm is exhausted in the return air plenum through the exhaust air damper. The remaining 5,000 cfm goes into the mixed air chamber.

At the same time, 1,000 cfm is exhausted; another 1,000 cfm is brought in through the outside air (OA) dampers in the mixed air plenum. This 1,000 cfm of outside air is mixed with the remaining 5,000 cfm of return air. The 6,000 cfm of mixed air then travels through the filters into the coil sections.

Ventilation is the process of supplying outside air to buildings in the proper amount to offset the contaminants and odors produced by people and equipment.
