Abstract

There is provided an internet-based method of controlling a mechanical system to which a resource such as energy or water is fed along at least one conduit The resource is consumed variably with respect 1o time and ambient conditions, whereby as the performance of the system changes, the pattern of consumption is altered. The method includes a) monitoring the pattern of consumption of the resource and ambient conditions, using the internet, b) through analysts of the pattern of resource use with respect to time at a central server, determining when a significant performance deficiency occurs; and c) altering the performance of the system.

Claims

1. An internet-based method of controlling a mechanical system to which a resource is fed along at least one conduit, the system having a variable consumption of the resource with respect to time and ambient conditions, such that as the performance of the system changes, the pattern of consumption is altered, the method comprising the following steps:

a) monitoring the said pattern of consumption of the resource and ambient conditions, using the internet;

b) through analysis of the pattern of resource use with respect to time at a central server, determining when a significant performance deficiency occurs; and

c) altering the performance of the system.

2. The method claimed in claim 1 in which the mechanical system is a clothes dryer, and an analysis of the consumption of energy with respect to time is used to more accurately determine the point of termination of the drying cycle, thereby improving the performance of the clothes dryer.

3. The method claimed in claim 1 in which the mechanical system is the water supply system for a building, and through analysis of the pattern of consumption of water with respect to time, the performance of toilets, cooling towers, fountains faucets and fixtures can be determined and corrected.

4. The method claimed in claim 1 in which the mechanical system is the heating system for a building, the pattern of fuel consumption and ambient conditions being used to determine and correct the heating performance of the building and heating plant.

5. The method claimed in claim 1 in which the mechanical system is a cooling system, the pattern of fuel consumption and ambient conditions being used to determine and correct the cooling performance of the building and the cooling system.

6. The method claimed in claim 1 in which the mechanical system is a refrigerator and analysis of the pattern of electrical consumption with respect to time is used to determine and correct the performance of the refrigerator.

7. The method claimed in claim 1 in which the mechanical system is a water heater and analysis of the pattern of energy and water use with respect to time is used to determine and correct the performance of the water heater.

8. The method claimed in claim 1 in which the resource monitoring means is an internet connection to the utility meters of the building.

9. The method claimed in claim 1 in which the means of control is by the provision of data and analysis through the internet to building owners and operators to enable the correction or replacement of defective equipment.

10. The method claimed in claim 1 in which the means of control is by a relay or controller located at the building site, which is in internet communication with the central server.

11. The method claimed in claim 3 in which the daily pattern of water consumption in multi-unit residential buildings is analysed over a period of time to create an index, this index being the average minimum value of the water consumed over a period, divided by the average value for that same period, such index being used as an indicator of water performance for the building.

12. The method claimed in claim 4 in which the pattern of fuel consumption is taken over a given period where the ambient daily temperature on each day is below 10 C, pattern of fuel consumption is related mathematically to the water consumption and outside temperature pattern for the same period to create a dimensionless energy efficiency index which determines the performance of the building and its heating system.

13. The method claimed in claim 6 in which the pattern of electrical consumption of the refrigerator, can be identified by its characteristic ON-OFF pattern and through analysis of the energy use determine the efficiency of the refrigerator and recommend corrective action.
