Project Workflows


Starting a Project

A new project can be added by the technician in the field or from another entity from the home office.

From the main screen, tap “Project.”

The user will see a project workflow for the program they are testing in. In this example, we will use the Entergy Arkansas workflow. Users can also start a project from scratch by selecting a Test Mode.

Click on the “Entergy Arkansas” project workflow. User will see something similar to Figure 2.2 and Figure 2.3.

As seen in Figure 2.3 the user can choose to either start a blank project or use cloud data that the user has previously saved or data that the home office has populated for them.

Project Name

In this example, the project name will default to {Entergy Arkansas [date] [time]}. This can be edited if required or desired.

Project Workflow

Project workflows are unique to each utility program and contain a series of steps to gather information or collect measurements about the HVAC system or performance of the HVAC system.

The red “X” indicates the information in this section is incomplete or has not been completed.


Project Information

Tap “Project” to add or see specific details about the project.

Adding Project Information

Using the drop down menu, fill out the project information. Add project notes if there are any and either tap “Submit” or tap the check mark in the upper right corner.

After submitting, a green check mark indicates the project information is complete and has been entered successfully.

A red “X” indicates that the information in the associated category is incomplete. Missing information may be added or revised at a later time.


Adding Job Site Information

mQ finds the general location of the building or site and the user must drag the blue pin to the exact address. The geolocation is then recorded.

Tap “Customer Information” and continue to fill out the form. All the fields in bold MUST be filled out. mQ automatically populates the address to the customer information and records the coordinates.

After filling out each section, a green check mark indicates the customer information is complete and that all the required building information has been added.

If the user doesn’t see the green check, go back and complete the information now highlighted in red.

(Note: User can acquire the utility account number from home owner and/or scan the barcode of the meter when required.)


Equipment Information & System Profile

mQ will prompt the user to drag the blue pin to the EXACT location of the equipment that will be tested. The equipment geolocation is then verified and recorded.

The blue circle may not move with the pin depending on if the user is connected to WiFi. Do not be alarmed if the circle does not move. mQ uses the pin location as the equipment location. A phone GPS at best has a repeatable accuracy of 50′.


Adding System Details Using the Barcode Scanning Camera

Select the Barcode Scanning Camera Icon to the right of the field you are entering to scan model and serial numbers.


• Scan using the barcode camera reader.

• Align the barcode with the camera.

• The barcode scanning camera will pop-up with a dialog box to access the camera.

• Press “Ok”


Manually Entering the Model Number

If the barcode scanner worked, then great, but always double check. Barcode information is set up by the equipment manufacturer.

Barcode reading is hit-or-miss. based on the manufacturer. You must double check your number, correct any mistakes or enter the model number by hand.


Add Equipment Tag Photo

mQ makes it easy so that photos don’t have to be uploaded from another device.

Take a photo by tapping “Take Photo.”

User should have a clear photo showing the product and model number. If not, re-take.

Photos of verifications are stored on the smart device as well as in the project for “export with PDF” reports.


System Profile

The system profile is one of the most important elements of completing a project. Information entered here will drive all of the performance and diagnostic tools in the measureQuick application.

Nominal tons will be used to calculate capacity and airflow, the refrigerant type is used for coil temperatures as well as superheat and subcooling calculations.

Nominal airflow or “design airflow” will be used to determine suction pressure targets.

SEER will be used to determine the head pressure targets

The metering device type is used to determine the target superheat and subcooling as well as the charging process.

The high efficiency evaporator switch is used for evaporator targets.

Superheat and subcooling targets are drivers for correct charge indication.

Total External Static Pressure is the driver for allowable duct pressures.

Extended Performance Ratings drive performance targets when more precise information about the system operation is known.

Electrical Information is used for electrical diagnostics.


Project Tasks

A/C System Test In & Test Out

At this point in the project or at anytime time before this point, the user must hook up their wireless probes/gauges to the unit. Data can be viewed graphically or in a list.

Tapping “View on mQ Home” will bring up the gauge representation.

Tapping “View” on the right of the workflow navigation buttons will bring up a list view of the data in each section.

Outdoor Measurements

Tap “View” to display the measurements that would typically be made outside at the system condenser. Any wireless probes that are hooked up to the unit will auto populate in their associated fields.

If there are no probes hooked up, a grey box will be there for the user to enter the data manually. When all fields are filled in, tap “Capture.” Capturing the data will freeze-frame the data and upload it into the form. Tap “Submit” and return to the Tune-Up screen.

Indoor Measurements & Electrical Measurements

Electrical measurements are used for determination of the SEER and EER calculations, fan efficacy as well as the capacitor health of the system.

Measurements can be entered the following ways:

• Phase to Ground

• Phases to Phase

• Power Directly

Using a Redfish iDVM550 Singe Phase Power Meter is the fastest and most precise way to measure electrical. The iDVM550 measures power and power factor directly. Otherwise the power factor is assumed.


Capacity Calculations

Tapping the Performance Calculations will show the actual as well as the normalized capacity. Capacity is normalized (corrected) for the following:

• Outdoor air temperature

• Indoor dry & wet bulb

• Airflow

• Voltage

• Line set length

System airflow is calculated using a mass flow equation and determines the CFM/Ton of cooling. The rated capacity used in the system profile multiplies the CFM/Ton by the nominal tonnage to determine the total system airflow. If the nominal capacity is not entered mQ will default to 1-ton (12,000 BTUh).


Weather Conditions

Weather conditions are used to correct the temperature pressure charts for elevations, and to assure that the test conditions are within the guidelines of the program requirements. Weather information is pulled from nearby weather stations.


Diagnostics

The diagnostics show what may be wrong with the unit you are analyzing. Flags can be cleared by the user after a determination is made that the issue does or does not exist.

The number next to the flag is a “symptom of” the fault being shown. In this case there are three symptoms of a dirty condenser,a nd over charge of refrigerant and a liquid line restriction as well as two symptoms of a loose TXV bulb. The symptoms are derived from the minor faults that can be viewed by tapping the + sign. The technician is to perform a visual inspections and other tests to determine what the fault actually is. In this case, cleaning the condenser coil may clear all other the faults listed.

When diagnostics are done being analyzed, the user can return to the Tune Up screen and tap “Save Data.”

Return to Task screen and continue through A/C System Test Out. When done with that section, tap “Submit” under the Task screen.


Review

Under the Review tab, take pictures as requested that are required by the program. Return to the Project Main screen and tap “Complete.”

A prompt will appear informing the user that the project was submitted successfully. The project can now be exited.


Results

Previous projects or exited projects can always be reopened by tapping “Results.” The user can tap the project they want to reopen and then tap “set as active.” That project is now the active project and can be edited.


Education

The Education tab is a resource available to the user to look up information about measureQuick and products that are used with the app.
