Creating Refrigerant Leak Settings

You can create specific requirements for those refrigerant or HVAC asset types based upon the guidelines and protocols for a specific country. In doing so, it provides consistency and precision for monitoring those assets within that country.

Leakthreshold Leakthreshold

Adjusting Leak Threshold

The next part of the process is to set the Leak Rate Threshold for all your refrigerated asset types. The rate that you set must be in compliance with all guidelines and protocols. It is necessary to check your local environmental agency for additional information. The thresholds you set for each of the four types of refrigerated asset types will be the same for all assets in that asset type. When any refrigerant or HVAC equipment is leaking and the leak rate meets or exceeds the specific threshold, Service Automation creates a leak record.

Calculating Methods

EPA outlines four acceptable methods that can be used either individually or in combination to assets full charge:

1. Equipment manufacturers' determination
2. Calculations based on component sizes, refrigerant density, volume of piping, and other considerations. 
3. Actual measurements of the amount of refrigerant added or evaluated from the appliance. 
4. Use of an established range based on the best available data. This method requires you to document how you determined the full charge. 

The full charge is necessary to determine the leak rate. For commercial refrigeration equipment, EPA says the trigger leak rate for a 12-month period is 35 percent of the full charge. According to the latest rule, there are two acceptable methods for calculating leak rate:

• 2790359160
• Rolling average

However, the equipment owner must select and consistently use only one method over the lifetime of all the appliances located at a facility.

Whenever the leak rate meets or exceeds the leak rate threshold you set for each refrigerant use purpose (Commercial Refrigeration, Industrial Refrigeration, Air Conditioning, or All Other Appliances), the system generates a leak record, also known as leak event.

If refrigerant is leaked based on various set trigger rates or exceeds the minimum thresholds, you must go back and inspect that asset. You can set the threshold based on a quarterly or yearly review based on the amount of refrigerant the asset holds.

PMpriority PMpriority

Refrigeration PM Priority

The Refrigeration PM Priority sets the priority assigned to all automatically generated Leak Inspection and Leak Detector Planned Maintenance Work Orders. Whenever a refrigerated asset has been repaired following a leak event, subsequent follow-up inspections are required to ensure the leak has been adequately repaired. The number of inspections required is dependent on the amount of refrigerant the asset holds. By setting all follow-up leak inspection work orders to the Refrigeration PM Priority, you will have an additional tool for monitoring your refrigerated assets. By default, the Refrigeration PM Priority is set to PM Leak Inspection.

CARB Report

Subscribers who operate refrigerated assets in the state of California are required to submit an annual report. The CARB Report is automatically generated from information contained within ServiceChannel. By selecting the Run CARB Report checkbox, the report will run once the user triggers the report from the Asset Manager module. Before running the CARB report, users must identify which assets are to be included in the report. This is done in the Asset Manager module. See CARB Reporting for more information.

Followupworkorder Followupworkorder

Follow-Up Work Order

You can specify whether a follow-up work order should be automatically created after the original service request is completed with the associated leak record left open.

Once a work order is moved to the Completed status while the associated leak record stays open, a follow-up request gets created and dispatched to the provider so that they can repair the leak and close the leak record. In the meantime, the provider can invoice the original service request.

Selecting this option ensures that no follow-ups get generated. Providers should first close leak records associated with work orders to be able to invoice them. When providers check out of a work order with a leak record left open and specify that they completed the requested service, the work order moves to the Completed / Open Leak Record status. The status signals that providers should go back to this work order to enter all the required leak record information before they can submit an invoice. With an open leak record, the work order cannot be moved to the Completed, Completed / Confirmed, or Completed / Pending Confirmation status. After the leak record is completed, the work order status changes to Completed / Pending Confirmation.

Refrigeranttrackingbylocation Refrigeranttrackingbylocation

Refrigerant Tracking by Location

You can decide whether refrigerant tracking should happen across all your locations or only at those where it’s required.

• For specific locations: Should you want to track refrigerant usage only at the locations where you have assets containing ozone-depleting refrigerants, the ServiceChannel team can activate refrigerant tracking only for these locations.
• For locations where there is no equipment with substances that are required to be tracked, the refrigerant tracking process can be deactivated. Turning off refrigerant tracking for a location implies that providers are not prompted to record information on refrigerants they use while servicing refrigeration or HVAC assets at the location.
• For all locations. You may need to track refrigerant usage across all your locations regardless of refrigerant types and quantities contained in assets at these locations. 

Once the ServiceChannel team configures this for you, the Refrigerant Leak Settings page displays locations the refrigerant tracking process is on.

While closing a leak inspection work order during the check-out process on a Planned Maintenance work order with at least one refrigerant asset, you can choose to add a requirement to select the leak inspection method used. There can be more than one method selected. In addition, the ability to add an acknowledge statement for users in Provider & Service Automation and SC Provider Mobile to confirm the leak inspection method. You can select at least one or all three platforms.
