Basic DRY-O-TRON
®
The basic DRY-O-TRON
®
controls the humidity in
the space and returns to the pool the heat it has lost
to evaporation.
The same amount of return air passes through the
evaporator and the evaporator bypass.
The outdoor-air intake flow rate can be up to 15%
of the total supply airflow rate, or up to 35% if the
unit has the air-conditioning option, depending on
outdoor temperature. The incoming outdoor air
must be heated (by others) to not less than 32°F
(0°C). There may be limitations on maximum flow
rates. See subsequent page in this manual.
Any unit with more than 15% outdoor air must have an auxiliary pool heater, which may be by others.
A built-in clock may limit the intake of outdoor air and/or the exhaust of room air to occupied periods only.
DRY-O-TRON
®
with Economizer
The economizer reduces the amount of energy
required for cooling by using a full flow of outdoor
air when possible.
The same amount of return air passes through
the evaporator and the evaporator bypass.
Under normal (not economizer) mode the
outdoor-air intake flow rate can be up to 15%
(or up to 35% with air-conditioning option) of the
total supply airflow rate, depending on outdoor
temperature.
Except in economizer mode, the incoming
outdoor air must be heated (by others) to not less
than 32°F (0°C). There may be limitations on
maximum flow rates. See subsequent page in
this manual.
In order to maintain a negative pressure on the
natatorium, the exhaust airflow rate should be 110% of the outdoor air intake flow rate.
When outdoor air conditions permit, the refrigeration system is automatically stopped and the room exhaust
air and outdoor air intake flow rates are varied to control temperature.
The outdoor-air intake damper(s) must be adjusted mechanically to limit the intake flow to maintain a slight
negative pressure on the room.
Natatoriums with DRY-O-TRON
®
units having the Economizer option must also have auxiliary pool heaters,
which may be by others.
Some units with the economizer option may also be equipped with the Intelligent Energy Saver option.
The Intelligent Energy Saver
® economizer reduces the amount of energy required for cooling and for
dehumidification by using an increased flow of outdoor air when possible. A preset amount of outdoor air is
brought in during occupied periods, and is increased only as necessary for dehumidification or cooling.
For more information on the Economizer option, refer to Appendix M5 - Economizer.
