Abstract
A fan coil for a single unit in a multi-unit building has hot and cold riser stacks. Heating and cooling closed loop fluid flow paths thermally connect the fan coil in thermal communication with the hot and cold riser stacks, respectively. The fan coil has a housing that houses heating and cooling heat exchangers in thermal communication with the heating and cooling closed loop fluid flow paths, respectively. A fan in the housing may draw ambient air through the fan coil. In a heating mode, the air collects heat from the heating heat exchanger and in a cooling mode, the air is cooled by the cooling heat exchanger. The heated or cooled air exits the fan coil and enters a room.
Claims21
A fan coil for a single unit in a multi-unit building, the multi-unit building having a hot riser stack and a cold riser stack wherein a heating closed loop fluid flow path thermally connects the fan coil in thermal communication with the hot riser stack and a cooling closed loop fluid flow path thermally connects the fan coil in thermal communication with the cold riser stack, the fan coil comprising:
- (a) a housing having an air distribution flow path;
- (b) a heating heat exchanger provided in the housing, the heating heat exchanger is in thermal communication with the heating closed loop fluid flow path;
- (c) a cooling heat exchanger provided in the housing, the cooling heat exchanger is in thermal communication with the cooling closed loop fluid flow path;
- and
- (d) a first fan and motor assembly provided in the housing and, when the fan coil is operating in a heating mode, ambient air flows through the fan coil and collects heat from the heating heat exchanger before exiting the fan coil and entering a room and when the fan coil is operating in a cooling mode, ambient air flows through the fan coil and is cooled by the cooling heat exchanger before exiting the fan coil and entering a room.
