Use it for drawing HVAC system diagrams, heating, ventilation, air conditioning, refrigeration, automated building control, and environmental control design floor
plans and equipment layouts.
"Ducts are used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. These needed airflows include, for example, supply air, return air, and exhaust air. Ducts also deliver, most commonly as part of the supply air, ventilation air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort.
A duct system is often called ductwork. Planning ('laying out'), sizing, optimizing, detailing, and finding the pressure losses through a duct system is called duct design." [Duct (HVAC). Wikipedia]
The vector stencils example "Design elements - HVAC ductwork" is included in HVAC Plans solution from the Building Plans area of ConceptDraw Solution Park.

This mechanical room HVAC plan sample shows the layout of air handler (air handling unit, AHU) equipment: mixing chamber, air filter, fan (blower), heat exchanger coil, diffusers.
"Ventilating (the V in HVAC) is the process of "changing" or replacing air in any space to provide high indoor air quality (i.e. to control temperature, replenish oxygen, or remove moisture, odors, smoke, heat, dust, airborne bacteria, and carbon dioxide). Ventilation is used to remove unpleasant smells and excessive moisture, introduce outside air, to keep interior building air circulating, and to prevent stagnation of the interior air.
Ventilation includes both the exchange of air to the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Methods for ventilating a building may be divided into mechanical/ forced and natural types.
"Mechanical" or "forced" ventilation is used to control indoor air quality. Excess humidity, odors, and contaminants can often be controlled via dilution or replacement with outside air. However, in humid climates much energy is required to remove excess moisture from ventilation air.
Ventilation increases the energy needed for heating or cooling, however heat recovery ventilation can be used to mitigate the energy consumption. This involves heat exchange between incoming and outgoing air. Energy recovery ventilation additionally includes exchange of humidity." [Ventilation (architecture). Wikipedia]

This HVAC schematics sample depicts the house cool mode of central air pool heater. It was drawn on the base of the HVAC schematics in the post "Central Air Pool Heater" from the Nathan Stratton's blog.
"With House Cool Mode, hot gas leaves the compressor runs through the reversing value into the condenser where it condenses into a liquid. Valve #1 is ON so liquid is able to leave the outside unit and run through the filter dryer and site glass into the evaporator upstairs in the house where the liquid flashes into a gas as it passes through the expansion valve and absorbs heat from the air passing through the evaporator. The cold gas travels downstairs and outside to the compressor and the cycle starts all over again." [robotics.net/ projects/ central-air-pool-heater/ ]

The vector stencil library "HVAC control equipment" contains 81 HVAC control equipment icons.
Use it for drawing HVAC system diagrams, heating, ventilation, air conditioning, refrigeration, automated building control, and environmental control design floor
plans and equipment layouts.
"HVAC (stands for Heating, Ventilation and Air Conditioning) is a control system that applies regulation to a heating and/ or air conditioning system. Usually a sensing device is used to compare the actual state (e.g., temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g., start the blower).
More complex HVAC systems can interface to Building Automation System (BAS) to allow the building owners to have more control over the heating or cooling units. The building owner can monitor the system and respond to alarms generated by the system from local or remote locations." [HVAC control system. Wikipedia]
