Abstract
An apparatus for controlling temperature and humidity of a conditioned space uses an outside air cooling coil circuit in fluid communication with coolant from a cooling supply. Outside air is introduced over the outside air cooling coil circuit through a damper having open and closed positions. A valve in fluid communication with the coolant supply and the outside air cooling coil circuit has an open setting for permitting and a closed setting for preventing the circulation of coolant through the outside air cooling coil circuit. An HVAC unit control is operatively associated with the valve and the damper for controlling their operation. An occupancy control generates a signal indicating the presence of a human within the conditioned space and is operatively associated with the HVAC unit control. The HVAC unit control, in response to a signal from the occupancy control indicating the presence of a human within the conditioned space, causes the damper to be open and enables the valve to be switched between the closed and open settings. A method of conditioning the air within a conditioned space provides an outside air cooling coil circuit. The presence or absence of a human within t…
