ABSTRACT:
Multiple coil fittings are connected in series to a closed loop single pipe circuit. Each coil fitting provides a paralleled chilled water flow to a fan coil servicing an enclosure. The coil fitting has a housing enclosing a first tubing for directing chilled water to the fan coil and a second tubing for directing return water to the pipe circuit. A baffle is mounted radially on the end of the second tubing proximal to the pipe circuit causing a portion of the chilled water in the pipe circuit to flow into the first pipe with the return water entering the pipe circuit below the baffle so there is no mixing of return water with the chilled water entering the first tubing regardless of the direction of flow in the pipe circuit. A humidistat mounted near the load coil farthest from the chiller sends a relative humidity signal to a diverter valve that changes the direction of chilled water flow in the pipe circuit.
