Which of the following is not a true statement about an all-water system?
Give this one a try later!
Since ventilation is controlled separately from heating and cooling,
acceptable indoor air quality is easily maintained
, Select the answer which best describes this system. Air is supplied to an undivided
conditioned space by a system capable of providing a warm or cool airflow as
required.

Single-duct single-zone variable air volume
In an air-and-water system, most of the heating and cooling is provided by water. The
air system only deals with ventilation needs, and hence there will be less airflow and
less dilution of contaminants. To compensate for this

The central system filters should be of higher efficiency than those typically
used in all-air systems
This system distributes hot or cold water or steam to terminal units in the zones for
heating or cooling, and relies on air ventilation combined with those terminal units or
separate arrangements that may include damper-controlled openings in the building
envelope or exhaust fans.

All-water system
This piping configuration uses one pipe to supply water and one to return it to the
boiler for re-heating od the chiller for re-cooling, depending on the season. This
