Abstract:
A humidity control kit to be used with a residential air conditioning system having a refrigeration coil in an air plenum and with a residential hot water heater having a cold water inlet and hot water outlet connected to a hot water tank, the kit comprising:a reheat coil sized-to fit downstream of the refrigeration coil in the air plenum;an inlet temperature monitor measuring the temperature of the air upstream of the refrigeration coil;an outlet temperature monitor measuring the temperature of the air downstream of the reheat coil;a pump unit providing controlled circulation of water from the hot water tank via the hot water outlet, through the reheat coil and back to the hot water tank via the cold water inlet when the pump unit is connected to the hot water heater and reheat coil via piping;a humidistat measuring an ambient humidity in air from the plenum; anda controller communicating with the inlet and outlet temperature monitors, the pump unit, and the air conditioning system to cause cooling of the refrigeration coils to lower the temperature of air entering the air plenum, and the circulation of water through the reheat coil to raise the temperature of air leaving the air plenum, so that inlet temperature monitor indicates temperature substantially equal to that indicated by the outlet temperature monitor, when the humidistat indicates that the ambient humidity is above a desired humidity setpoint.
