Abstract

Described herein are systems and methods for displaying HVAC information. One embodiment provides a method for displaying HVAC information including obtaining data indicative of a plurality of HVAC components of an HVAC system. For example, this data may be maintained by a building management system. The method further includes defining data indicative of a display object for rendering on a client display, the display object including a plurality of geometrically arranged indicator blocks, wherein each indicator block is associated with a respective HVAC component. For the purposes of this display object, each indicator block is bound with respective source of comfort level data for its associated HVAC component. Display characteristics are defined for each indicator block responsive to the comfort level data. The display characteristics are selectively modified responsive to changes in the comfort level data. The resulting display object is referred to as a “comfort map” for the present purposes.

Claims

1. A method for displaying information in relation to a Heating, Ventilation and Air Conditioning (HVAC) system, the method including;

obtaining data indicative of a plurality of HVAC components of an HVAC system;

defining data indicative of a display object for rendering on a client display, the display object including a grid defined by a plurality of commonly-sized geometrically arranged indicator blocks, wherein each indicator block is associated with a respective unique HVAC component;

binding each indicator block with a respective source of comfort level data for its associated HVAC component; and

for each indicator block;

(i) identifying comfort level data obtained from the source with which that block is bound, wherein the comfort level data includes a measured temperature value;

(ii) comparing the obtained comfort level data with a predefined comfort setpoint for that block, wherein the comfort setpoint includes a predefined preferred temperature value;

(iii) setting a display attribute for the block based on the relationship between the obtained comfort level data and the predefined comfort setpoint; and

(iv) repeating steps (i) to (iii) thereby to, on an ongoing basis, modify the display attribute responsive to changes in the comfort level data.

2. A method according to claim 1 wherein the plurality of HVAC components include a plurality of Air Terminal Units (ATUs).

3. A method according to claim 2 wherein each indicator block is associated with a respective ATU.

4. A method according to claim 1 wherein the display characteristics visually indicate whether a region serviced by the relevant HVAC component satisfies predefined comfort parameters.

5. A method according to claim 1 wherein the display characteristics include the colour of the indicator block.

6. A method according to claim 1 wherein the display component is sized responsive to the number of HVAC components.

7. A method according to claim 1 wherein the indicator blocks are quadrangular.

8. A method according to claim 1 wherein rows in the grid represent a first HVAC system attribute and columns in the grid represent a second HVAC system attribute.

9. A method according to claim 1 wherein a given indicator block, when rendered on a client display, provides an interactive object for accessing additional information describing its associated HVAC component.

10. A method according to claim 1 wherein the source of comfort level data is a data reference in a building management system.

11. A method according to claim 10 wherein the data reference is indicative of a value derived from analysis of one or more point values associated with the relevant HVAC component.

12. A method according to claim 1 wherein the source of comfort level data is an HVAC component.

13. A method according to claim 1 wherein the comfort level data is derived from two or more measured parameters including temperature data.

14. A method according to claim 13 wherein the two or more measured parameters include humidity data.

15. A non-transitory computer readable medium containing code that, when executed on one or more processors, causes the processors to perform a method according to claim 1.

16. A computer system comprising:

a memory for storing software instructions;

a processor coupled to the memory, the processor configured to read and execute software instructions in the memory to;

obtain data indicative of a plurality of Heating, Ventilation and Air Conditioning (HVAC) components of an HVAC system;

define data indicative of a display object for rendering on a client display, the display object including a plurality of geometrically arranged indicator blocks, wherein each indicator block is associated with a respective unique HVAC component;

bind each indicator block with a respective source of comfort level data for its associated HVAC component; and

for each indicator block,

(i) identifying comfort level data obtained from the source with which that block is bound, wherein the comfort level data includes a measured value;

(ii) comparing the obtained comfort level data with a predefined comfort setpoint for that block, wherein the comfort setpoint includes a predefined preferred value;

(iii) setting a display attribute for the block based on the relationship between the obtained comfort level data and the predefined comfort setpoint; and

(iv) repeating steps (i) to (iii) thereby to, on an ongoing basis, modify the display attribute responsive to changes in the comfort level data.
