Abstract
A system includes multiple HVAC systems. After receiving a demand request, a multiple-system controller a first anticipated power consumption associated with operating a first HVAC system at a first temperature setpoint during a future period of time of the demand response request and a second anticipated power consumption associated with operating a second HVAC system at a second temperature setpoint during the future period of time. Based at least in part on the first and the second anticipated power consumptions, a staging schedule is determined that indicates when to operate the first and second HVAC systems.
Claims20
A system comprising:
- a first heating, ventilation, and air conditioning (HVAC) system configured to regulate a first temperature of a first space based on a first temperature setpoint;
- a second HVAC system configured to regulate a second temperature of a second space based on a second temperature setpoint, wherein the second HVAC system is different from the first HVAC system;
- and
- a multiple-system controller communicatively coupled to the first HVAC system and the second HVAC system, the multiple system controller comprising:
- a memory configured to store enrollment data indicating which HVAC systems are participating in an automatic demand response operation;
- and
- a processor communicatively coupled to the memory and configured to:
- receive a demand response request indicating an upper limit on combined power consumption by the first and second HVAC systems during a future period of time;
- determine, based on the enrollment data, that both the first HVAC system and the second HVAC system are participating in the automatic demand response operation;
- determine a first anticipated power consumption associated with operating the first HVAC system at the first temperature setpoint during the future period of time of the demand response request;
- determine a second anticipated power consumption associated with operating the second HVAC system at the second temperature setpoint during the future period of time of the demand response request;
- determine, based at least in part on the first anticipated power consumption and the second anticipated power consumption, a staging schedule indicating when the first HVAC system is either turned on or turned off, and when the second HVAC system is either turned on or turned off;
- and
- operate the first HVAC system and the second HVAC system according to the determined staging schedule.

A method of operating a first heating, ventilation, and air conditioning (HVAC) system configured to regulate a first temperature of a first space based on a first temperature setpoint and a second HVAC system configured to regulate a second temperature of a second space based on a second temperature setpoint, the method comprising:
- receiving a demand response request indicating an upper limit on combined power consumption by the first and second HVAC systems during a future period of time;
- determining, based on enrollment data, that both the first HVAC system and the second HVAC system are participating in an automatic demand response operation, the enrollment data indicating which HVAC systems are participating in the automatic demand response operation;
- determine a first anticipated power consumption associated with operating the first HVAC system at the first temperature setpoint during the future period of time of the demand response request;
- determining a second anticipated power consumption associated with operating the second HVAC system at the second temperature setpoint during the future period of time of the demand response request;
- determining, based at least in part on the first anticipated power consumption and the second anticipated power consumption, a staging schedule indicating when the first HVAC system is either turned on or turned off, and when the second HVAC system is either turned on or turned off;
- and
- operating the first HVAC system and the second HVAC system according to the determined staging schedule.
