Abstract

A data collection system allows occupants in one or more locations to provide indications as to their respective levels of comfort. The indications as to comfort level are preferably provided through personal computers in these locations. Each computer is programmed to display a menu of comfort level options that may be selected by the user of the computer. Each computer is operative to require that any selected comfort level be accompanied by a verification as to the user making the one or more selections. The verification preferably requires an entry of an identification that may be checked against a stored identification. Each computer is operative to timely provide the selections as to comfort level by a recognized user to a network computer. The network computer is operative to analyze the comfort level information from these computers and send one or more commands to an HVAC system providing conditioned air to the locations.

Claims

1. A process for collecting information for the control of one or more systems that provide conditioned air to a plurality of locations, said process comprising the steps of:

providing for the entry of at least one level of comfort in a plurality of data entry devices at each location;

requiring that the entry of at least one level of comfort at each data entry device be accompanied by an entry of an identification of the person making the entry of comfort level; and

verifying that the entered identification is recognized by the data entry device.

2. The process of claim 1 wherein said step of verifying that the entered identification is recognized comprises the step of:

comparing the entered identification with at least one previously stored identification to determine whether the entered identification matches the previously stored identification.

3. The process of claim 2 wherein said step of providing for the entry of at least one level of comfort in a plurality of data entry devices comprises the step of generating a menu of different comfort levels that may be selected at each data entry device, and wherein said process further comprises:

storing at least one comfort level that is selected in the data entry device when the entered identification matches a previously stored identification.

4. The process of claim 1 wherein said step of providing for the entry of at least one level of comfort in a plurality of data entry devices comprises the step of generating a menu of different comfort levels that may be selected at each data entry device;

and wherein said process further comprises;

storing at least one comfort level that is selected in the data entry device when the entered identification is recognized.

5. The process of claim 1 further comprising the steps of:

collecting information as to the levels of comfort entered at the data entry devices at each location that are accompanied by an entered identification that is recognized by the data entry device;

determining the overall level of comfort for particular groupings of data entry devices from the collected information as to the levels of comfort entered into the data entry devices; and

transmitting indications as to the overall level of comfort for the particular groupings of data entry devices to at least one system that provides conditioned air to the plurality of locations.

6. The process of claim 5 wherein said step of collecting information as to the levels of comfort entered at the data entry devices at each location comprises the step of:

collecting information as to the levels of comfort entered at the data entry devices by the particular location in which the levels of comfort were entered whereby the overall level of comfort for a particular grouping of data entry devices is determined with respect to the collected information at the particular location.

7. The process of claim 5 wherein said step of determining the overall level of comfort for particular groupings of data entry devices comprises the steps of:

computing an overall level of comfort for each particular grouping of data entry devices;

determining whether the computed level of comfort for each particular grouping of data entry devices exceeds a threshold value for assigning a particular overall level of comfort; and

assigning a particular level of comfort for each particular grouping of data entry devices when the computed level of comfort exceeds the threshold value.

8. The process of claim 5 wherein each particular grouping of data entry devices is provided with a unique identifier and wherein said step of determining the overall level of comfort for each particular grouping of data entry devices comprises the step of:

computing an overall level of comfort for each particular grouping of data entry devices as a function of the information collected as to the levels of comfort entered at the data entry devices having the unique identifier for each particular grouping of data entry devices.

9. The process of claim 1 wherein each data entry device is a personal computer.

10. A system for providing conditioned air to a plurality of locations, said system comprising:

a plurality of data entry devices at each location, each data entry device being operative to provide for the selection of at least one level of comfort at the location, each data entry device being furthermore operative to require that the selection of at least one comfort level be accompanied by the entry of an identification of the person using the data entry device;

at least one computer in communication with the plurality of data entry devices, said computer being operative to collect information as to the selections of comfort level entered at the data entry devices that are accompanied by a verified entry of an identification of the person using the device and being furthermore operative to determine overall levels of comfort for each location from the collected information; and

at least one HVAC control being operative to control the provision of conditioned air to the locations in response to the determination of overall levels of comfort for each location.

11. The system of claim 10 wherein each data entry device is operative to generate a menu of different comfort levels that may be selected and entered at each data entry device.

12. The system of claim 11 wherein each data entry device is operative to store the entry of a particular comfort level from among the different comfort levels in the menu when the identification of the user is verified by the data entry device.

13. The system of claim 12 wherein each data entry device is operative to provide the stored entry of a particular comfort level to the at least one computer in communication with the plurality of data entry devices.

14. The system of claim 10 wherein each data entry device is a personal computer.

18. The system of claim 10 wherein each data entry device is a personal computer.

15. A system for providing conditioned air to at least one location, said system comprising:

a plurality of data entry devices at the location, each data entry device being operative to provide for the selection of at least one level of comfort at the location, each data entry device being furthermore operative to require that the selection of at least one comfort level be accompanied by the entry of an identification of the person using the data entry device;

at least one computer in communication with the plurality of data entry devices, said computer being operative to collect information as to the selections of comfort level entered at the data entry devices that are accompanied by a verified entry of an identification of the person using the device and being furthermore operative to determine an overall level of comfort for the location from the collected information; and

at least one HVAC control being operative to control the provision of conditioned air to the location in response to the determination of an overall level of comfort for the location.

16. The system of claim 15 wherein each data entry device is operative to generate a menu of different comfort levels that may be selected at the particular data entry device.

17. The system of claim 16 wherein each data entry device is operative to store the selection of a particular comfort level from among the different comfort levels in the menu provided that the identification of the person using the data entry device is verified.
