Abstract

Claims (27)

1. A method for controlling air temperature in a building, comprising:

obtaining as user input a target rate for achieving a target air temperature in the building, wherein the target rate includes a target time at which the target air temperature is to be achieved; and

operating a heating ventilation and air-conditioning (HVAC) system to achieve the target rate, wherein the operating comprises:

operating the HVAC system according to an initial control plan;

determining an actual rate at which the target air temperature is achieved, wherein the actual rate includes an actual time taken to achieve the target air temperature;

determining a modified control plan when the actual rate is not same as the target rate; and

operating the HVAC system according to the modified control plan.

2. The method of claim 1 , further comprising:

periodically repeating the steps of determining the actual rate, determining the modified control plan and operating the HVAC system according to the modified control plan.

3. The method of claim 1 , determining the modified control plan comprises:

obtaining a measurement of the air temperature in the building;

determining, based on the measurement, a rate of temperature change associated with a capacity at which the initial control plan is operating the HVAC system; and

modifying the capacity at which the modified control plan is to operate the HVAC system, based on the rate of temperature change.

4. The method of claim 1 , wherein the initial control plan includes operating the HVAC system at a first capacity.

5. The method of claim 4 , wherein the first capacity is a minimum capacity at with the HVAC system can be operated.

6. The method of claim 4 , further comprising:

determining that the actual rate is lower than the target rate;

wherein determining the modified control plan comprises determining the modified control plan to operate at least one equipment of the HVAC system at a second capacity which is higher than the first capacity.

7. The method of claim 4 , further comprising:

determining that the actual rate is higher than the target rate;

wherein determining the modified control plan comprises determining the modified control plan to operate at least one equipment of the HVAC system at a second capacity which is lower than the first capacity.

8. The method of claim 1 , further comprising:

receiving a heating call or a cooling call;

wherein the operating the HVAC system to achieve the target rate is in response to receiving the heating call or the cooling call.

9. The method of claim 1 , further comprising:

comparing the actual time taken to achieve the target air temperature with the target time to achieve the target air temperature; and

determining that the actual rate is not same as the target rate when the actual time taken is not same as the target time.
