Abstract
A single unit HVAC system for a unit in a multi-unit building comprises a first heat exchanger thermally connected to a riser stack, a plurality of fan coils, each fan coil comprising a unit heat exchanger and a motor and fan assembly wherein, in operation, the motor and fan assembly delivers air to a location in the unit, and a closed loop fluid flow path extending between the first heat exchanger and the plurality of unit heat exchangers. In operation, the first heat exchanger exchanges heat between the riser stack fluid and the closed loop fluid, each unit heat exchanger exchanges heat between the closed loop fluid and air that is delivered to a different room in the unit.
Claims20
A multi-unit building HVAC system comprising:
- (a) a riser stack;
- and,
- (b) a first single unit HVAC system for a unit in a multi-unit building, the first single unit HVAC system comprising:
- i) a first heat exchanger thermally connected to the riser stack;
- ii) a first fan coil comprising a first unit heat exchanger and a first motor and fan assembly wherein, in operation, the first motor and fan assembly delivers air to a first location in the unit;
- iii) and a second fan coil comprising a second unit heat exchanger and a second motor and fan assembly wherein, in operation, the second motor and fan assembly delivers air to a second location in the unit;
- and,
- iv) a closed loop fluid flow path extending from the first heat exchanger and to each of the first unit heat exchanger and the second unit heat exchanger prior to returning to the first heat exchanger,
- wherein, when the closed loop fluid is being circulated in the closed loop fluid flow path and the first and second motor and fan assemblies are in operation, the first heat exchanger exchanges heat between the riser stack fluid and the closed loop fluid, the first unit heat exchanger exchanges heat between the closed loop fluid and air that is delivered to the first location in the unit, and the second unit heat exchanger exchanges heat between the closed loop fluid and air that is delivered to the second location in the unit.
A multi-unit building HVAC system comprising:
- (a) a riser stack;
- and,
- (b) a first single unit HVAC system for a unit in a multi-unit building, the first single unit HVAC system comprising:
- i) a first heat exchanger thermally connected to the riser stack;
- ii) a first fan coil comprising a first unit heat exchanger and a first motor and fan assembly wherein, in operation, the first motor and fan assembly delivers air to a first location in the unit;
- iii) and a second fan coil comprising a second unit heat exchanger and a second motor and fan assembly wherein, in operation, the second motor and fan assembly delivers air to a second location in the unit;
- and,
- iv) a closed loop fluid flow path extending between the first heat exchanger the first fan coil and the second fan coil, wherein the closed loop fluid flow path is connected in series with the first and second fan coils.
A multi-unit building HVAC system comprising:
- (a) a riser stack;
- and,
- (b) a first single unit HVAC system for a unit in a multi-unit building, the first single unit HVAC system comprising:
- i) a first heat exchanger thermally connected to the riser stack;
- ii) a first fan coil comprising a first unit heat exchanger and a second fan coil comprising a second unit heat exchanger;
- and,
- iii) a closed loop fluid flow path extending from the first heat exchanger and to each of the first unit heat exchanger and the second unit heat exchanger prior to returning to the first heat exchanger,
- wherein, in operation, the first heat exchanger exchanges heat between a riser stack fluid in the riser stack and a closed loop fluid in the closed loop fluid flow path, and each of the fan coils is operable to modulate a temperature of a portion of the unit.
