1. A system for controlling water distribution in systems used in at least one of a heating, ventilation, air conditioning, refrigeration, fluid heating and chilling configuration for heating or cooling a space or a fluid, the system comprising:
a cold water supply adapted to supply cold water;
a hot water supply adapted to supply hot water;
a plurality of fan coil devices;
a cold water supply line in fluid communication with the cold water supply;
a hot water supply line in fluid communication with the hot water supply;
a plurality of control valve devices, wherein:
one or more of the plurality of control valve devices comprises a first three-way control valve and a second three-way control valve,
the first three-way control valve is coupled to the second three-way control valve, and
the plurality of control valve devices comprises:
a cold water inlet in fluid communication with, and configured to receive cold water from, the cold water supply line;
a cold water outlet in fluid communication with, and configured to supply cold water to, the cold water supply line;
a cold water output in fluid communication with, and configured to supply cold water from, the cold water supply to at least one of the plurality of fan coil devices;
a cold water return inlet in fluid communication with, and configured to receive from, at least one of the plurality of fan coil devices, the cold water being supplied by the cold water output, and the cold water being output to the cold water supply line via the cold water outlet;
a hot water inlet in fluid communication with the hot water supply line;
a hot water return outlet in fluid communication with the hot water supply line;
a hot water output in fluid communication with, and configured to supply hot water from, the hot water supply to at least one of the plurality of fan coil devices; and
a hot water return inlet in fluid communication with, and configured to receive from, at least one of the plurality of fan coil devices, the hot water being supplied by the hot water output, and such hot water being output to the hot water supply line via the hot water return outlet;
a plurality of cold water tees, comprising:
at least one cold water tee connected to the cold water supply line comprising a first cold water outlet connected to the cold water inlet of a first control valve device, and a second cold water outlet connected to the cold water inlet of a second control valve device; and
at least one cold water tee connected to the cold water supply line comprising a first cold water inlet connected to the cold water return outlet of a first control valve device, and a second cold water inlet connected to the cold water return outlet of a second control valve device;
a plurality of hot water tees, comprising:
at least one hot water tee connected to the hot water supply line comprising a first hot water outlet connected to the hot water inlet of a first control valve device, and a second hot water outlet connected to the hot water inlet of a second control valve device; and
at least one hot water tee connected to the hot water supply line comprising a first hot water inlet connected to the hot water return outlet of a first control valve device, and a second hot water inlet connected to the hot water return outlet of a second control valve device;
at least one thermostat configured to sense a temperature of at least one of the space or the fluid; and
at least one pump in fluid communication with a fan coil device of the plurality of fan coil devices and at least one of the cold water output and the hot water output of a control valve of the plurality of control valves,
wherein:
the at least one pump is configured and positioned to selectively receive both hot water and cold water from the control valve, and
the at least one thermostat is in communication with at least one of a control valve of the plurality of control valves, the at least one pump, and a fan coil device of the plurality of fan coil devices, and is configured to selectively control at least one of a flow rate of cold water or a flow rate of hot water through the control valve, pump, and fan coil device.
