Abstract
A heating, ventilation and air-conditioning (HVAC) system is provided. The HVAC system includes a first HVAC unit, a second HVAC unit including a battery, a panel receptive of grid power and a switch element. The switch element is separate from the panel and configured to assume a first state in which electricity is transmissible from the panel to the first and second HVAC units when the grid power is available and a second state in which electricity is transmissible from the battery to the first HVAC unit when the grid power is unavailable.
Claims20
A heating, ventilation and air-conditioning (HVAC) system, comprising:
- a first HVAC unit;
- a second HVAC unit comprising a battery;
- a panel receptive of grid power;
- and
- a switch element separate from the panel and configured to assume:
- a first state in which electricity is transmissible from the panel to the first and second HVAC units when the grid power is available, and
- a second state in which electricity is transmissible from the battery to the first HVAC unit when the grid power is unavailable.
A heating, ventilation and air-conditioning (HVAC) system, comprising:
- a first HVAC unit;
- a second HVAC unit comprising a battery;
- a panel receptive of grid power;
- first and second power lines by which electricity is transmissible from the panel to the first and second HVAC units, respectively;
- and
- a switch element separate from the panel and configured to assume:
- a first state in which electricity is transmissible from the panel to the first and second HVAC units via the first and second power lines, respectively, when the grid power is available, and
- a second state in which the first and second power lines are electrically open and electricity is transmissible from the battery to the first HVAC unit when the grid power is unavailable.
A method of retrofitting a heating, ventilation and air-conditioning (HVAC) system with battery switching,
- the HVAC system initially comprising first and second power lines electrically interposed between a panel, which is receptive of grid power, and first and second HVAC units, respectively,
- the method comprising:
- disposing first and second switches separately from the panel and along the first and second power lines, respectively;
- and
- configuring the first and second switches to assume:
- a first state in which electricity is transmissible from the panel to the first and second HVAC units via the first and second power lines, respectively, when the grid power is available, and
- a second state in which the first and second power lines are electrically open and electricity is transmissible from a battery of the second HVAC unit to the first HVAC unit when the grid power is unavailable.
