Normal Cooling
Refrigerant flows from the outdoor condenser through the
normally open Cooling Valve (CV.x) to the expansion
device. Reheat1 Valve (RH1.x) and Reheat2 Valve
(RH2.x) are closed.
Reheat1 (Subcooling Mode) -- 50TC04--07
This mode increases latent cooling and decreases sensible
cooling compared to normal cooling. Refrigerant flows
from the outdoor condenser, through the normally open
Reheat1 Valve (RH1.x), and through the reheat condenser
coil to the expansion device. Cooling Valve (CV.x) and
Reheat2 Valve (RH2.x) are closed.
Reheat2 (Hot Gas Reheat Mode) --50TC04--07
This mode provides maximum latent cooling with little to
no sensible capacity. This mode can operate to provide
dehumidification when there is no cooling demand. Like
Reheat1 mode, refrigerant flows from the outdoor
condenser, through the normally open Reheat1 Valve
(RH1.x), and through the reheat condenser coil to the
expansion device. The Cooling Valve (CV.x) is closed.
Reheat2 Valve (RH2.x) is open which provides some
compressor discharge gas to the reheat condenser to
further increase the reheat of the evaporator airstream.
