REFRIGERATION FLOW DIAGRAM

27 DryAire Systems

DEHUMIDIFIER ONLY [Fig. 1]

The DryAire dehumidifier installed by itself will always

discharge warm dry air back to the room. The dis-

charge air temperature will be approximately 10°F to

20°F above the inlet air temperature. The moisture

content of the air will also contribute to the tempera-

ture rise.

If the discharge of warm supply air becomes a con-

cern, especially during summer months, we recom-

mend an optional Remote Outdoor Condenser that

properly matches the system.

REMOTE OUTDOOR

AIR-COOLED CONDENSER

[Fig. 2-3]

The addition of a DryAire remote outdoor condenser

will transform the dehumidifier into an air conditioner

and allow cool dry air to discharge back into the

room. The cool dry discharge air temp will be approx-

imately 10°F to 20°F below the inlet air temperature.

This function is controlled by an automatic change

over thermostat.

SYSTEM DESIGN

When the DryAire de-humidistat control calls for

dehumidification, the thermostat monitors the room

temperature; if the temperature is above the set-

point, the changeover thermostat will automatically

switch to cooling mode.

An electronically operated solenoid valve will divert

the flow of refrigerant from the internal condenser in

the dehumidifier to the outdoor remote condenser,

allowing the dehumidifier to discharge cool dry air

into the room.

When the thermostat is satisfied and the room tem-

perature falls below the heating setpoint, the thermo-

stat will automatically call for heat and the solenoid

valve will divert the refrigerant back to the internal

condenser located in the dehumidifier and discharge

warm dry air.
