Abstract

A system and method for asset management including tracking refrigerant characteristics is disclosed. The system includes a database including information relating to a refrigerant system and a database including information relating to service technicians. A server is programmed to track a refrigerant characteristic and to provide notifications to a user relating to the refrigerant characteristic.

Claims

1. A network-based equipment management system for managing a plurality of pieces of equipment located at a plurality of locations of an enterprise, the system comprising:

(a) a central processor accessible at the plurality of locations on a computer network;

(b) a database in communication with the central processor, the database configured to store;

(i) asset information relating to each of the plurality of pieces of equipment, wherein the information comprises at least a refrigerant level; and

(ii) service provider information;

(c) tracking software associated with the central processor, the tracking software configured to track at least one of a refrigerant leak rate, refrigerant usage, and refrigerant service events of each of the plurality of pieces of equipment;

(d) repair/retirement/retrofit coordination software associated with the central processor, the repair/retirement/retrofit coordination software configured to generate prompts for a user and further to generate a customized repair/retirement/retrofit plan based on input provided by the user, wherein the repair/retirement/retrofit coordination software is configured to generate a repair plan comprising;

(i) distributing a first notification regarding a first deadline for a first service attempt of a piece of equipment requiring service; and

(ii) if the first service attempt is unsuccessful, distributing a second notification regarding a second deadline for a second service attempt of the piece of equipment requiring service; and

(e) at least one predetermined limited user access level programmed into the central processor, wherein the at least one predetermined limited user access level is configured to restrict access of at least one user to solely a predetermined subset of the asset and service provider information based on a configurable user profile of the user, wherein the predetermined subset of the asset and service provider information is less than all of the asset and service provider information.

2. The system of claim 1, further comprising leak rate calculation software associated with the central processor, the leak rate calculation software configured to calculate the refrigerant leak rate.

3. The system of claim 2, wherein the leak rate is expressed as the percent of full charge that would be lost per 12-month period, using the following equation:

4. The system of claim 1, wherein if the second service attempt is successful, the repair/retirement/retrofit coordination software is further configured to distribute a notification regarding a testing deadline.

5. The system of claim 1, wherein if the second service attempt is unsuccessful, the repair/retirement/retrofit coordination software is further configured to distribute a third notification regarding a third deadline for a third service attempt of the piece of equipment requiring service.

6. The system of claim 1, wherein the information relating to each of the plurality of pieces of equipment further comprises a full charge capacity of at least one of the plurality of pieces of equipment, a refrigerant type of at least one of the plurality of pieces of equipment, and at least one prior work order of at least one of the plurality of pieces of equipment.

7. A network-based equipment management system for managing a plurality of pieces of equipment located at a plurality of locations of an enterprise, the system comprising:

(a) a central processor accessible at the plurality of locations on a computer network;

(b) a database in communication with the central processor, the database configured to store;

(i) asset information relating to each of the plurality of pieces of equipment, wherein the information comprises at least a refrigerant level; and

(ii) service provider information;

(c) tracking software associated with the central processor, the tracking software configured to track at least one of a refrigerant leak rate, refrigerant usage, and refrigerant service events of each of the plurality of pieces of equipment;

(d) identification software associated with the central processor, the identification software configured to automatically identify an appropriate service provider for a particular piece of equipment based on the particular piece of equipment and the service provider information;

(e) at least one predetermined limited user access level programmed into the central processor, wherein the at least one predetermined limited user access level is configured to restrict access of at least one user to solely a predetermined subset of the asset and service provider information based on a configurable user profile of the user, wherein the predetermined subset of the asset and service provider information is less than all of the asset and service provider information; and

(f) at least one client processor in communication with the central processor, the client processor being configured to allow the appropriate service provider to enter service information relating to maintenance or repair performed on the particular piece of equipment.

8. The system of claim 7, further comprising notification software associated with the central processor, the notification software configured to generate a notification and distribute it to at least one user.

9. The system of claim 8, wherein the at least one user is an owner, an operator, or the appropriate service provider.

10. The system of claim 7, wherein the client processor is further configured to allow the at least one user to access information about the particular piece of equipment or enter information via the client processor.

11. The system of claim 7, wherein the client processor comprises a computer or a kiosk.

12. The system of claim 7, further comprising notification software associated with the central processor, the notification software configured to generate a notification and distribute it to at least the appropriate service provider.

13. The system of claim 7, wherein the service information comprises identification of the particular piece of equipment, a name of an owner of the particular piece of equipment, location of the particular piece of equipment, identification of a system of which the particular piece of equipment is a part, a description of the maintenance or repair;

date of the maintenance or repair;

a service reference number; and

refrigerant information.

14. The system of claim 7, wherein the tracking software is further configured to calculate the refrigerant leak rate based on the service information entered by the appropriate service provider.

15. The system of claim 7, the client processor being further configured to allow the appropriate service provider to access information about the particular piece of equipment.

16. A network-based equipment management system for managing a plurality of pieces of equipment located at a plurality of locations of an enterprise, the system comprising:

(a) a central processor accessible at the plurality of locations on a computer network;

(b) a database in communication with the central processor, the database configured to store asset information relating to each of the plurality of pieces of equipment, wherein the information comprises at least a refrigerant level;

(c) tracking software associated with the central processor, the tracking software configured to track at least one of a refrigerant leak rate, refrigerant usage, and refrigerant service events of each of the plurality of pieces of equipment;

(d) notification software associated with the central processor, the notification software configured to;

(i) allow a user to select criteria for a notification;

(ii) allow the user to select a schedule for the notification; and

(iii) generate and distribute the notification based on the criteria and the schedule; and

(e) at least one predetermined limited user access level programmed into the central processor, wherein the at least one predetermined limited user access level is configured to restrict access of at least one user to solely a predetermined subset of the asset information based on a configurable user profile of the user, wherein the predetermined subset of the asset information is less than all of the asset information.
