Compared to water, air masses have a lower heat capacity. This means that they cool down faster, but they also raise the room temperature in a short time. Low thermal inertia allows literally in a few minutes to heat different in volume buildings. At the same time, all the heat goes only to heat the

An alternative to a constant air volume system is a variable air volume (VAV) system. Variable air volume systems are generally more complex than their CAV counterparts because they must utilize temperature control and control the actual volume of air blown into each room. Although more difficult to

for re-heating. The supply plenum directs air from the central unit to the rooms which the system is designed to heat. Regardless of type, all air handlers consist of an air filter, blower, heat exchanger/element/coil, and various controls. Like any other kind of central heating system, thermostats

Typically, the regulator damper is made of lightweight aluminum, and the self-balancing mechanism consists of plastic levers and transmission, a steel spring and silicone vibration dampers, which are necessary to prevent auto-oscillation.
345:
The basis of any CAV regulator is the self-balancing mechanism. It is the design of this mechanism that determines the accuracy of maintaining the set flow rate, noise level, minimum regulator resistance, flow range and other parameters.
401:
Disadvantages: require ducts with large cross-sections, it is necessary to reserve the supply unit and pump in the piping assembly, have a high gradient of air temperature over the height, have a small range of the jet.
275:
Air source types may not be suitable for cold climates unless used with backup (secondary) source of heat. Newer models may still provide heat when coping with temperatures below 0 °C (32 °F).

Self-balancing mechanism based on a silicone adjustment diaphragm that changes its volume depending on the air pressure in the duct, thereby increasing or decreasing the air flow area.
356:
Self-balancing mechanism with overlapping section. The self-balancing damper with spring automatically closes the remaining part of the cross-section depending on the duct pressures.
278:
A refrigerant coil is located in the air handler instead of a burner/heat exchanger. The system can also be used for cooling, just as any central air-conditioning system.
390:
Disadvantages: high noise level, disperse dust, each unit requires a supply of heat transfer fluid and electricity, have a high gradient of air temperature over height.

Advantages: presentable from a design point of view (only the grilles are visible), inexpensive (considering the combination with the ventilation system).
