Health Compliance Package – Filter Replacement

Objective/Method/Outcome

Objective: Determines if the filter needs replacement

Method: Calculates if differential pressure is over 20% than average. If the DP is over 20%, for more than the acceptable amount of time, an insight is triggered.

Outcome: To calculate an urgency score, the ventilation impact and an insight.

Description

Monitors filter differential pressure and compares it to average values from the previous 60 days to determine if filter may need to be replaced.

This rule is part of the CopperTree Standard ruleset.

Default Priority

Medium

Diagnosis

  1. Check filter.
  2. Replace filter if necessary.

Message

Filter may need to be replaced, differential pressure is higher than historical average.

Inputs

Input Unit Tags Description
Filter DP   Filter Differential Pressure The recorded filter differential pressure
Threshold – Max DP Above Range %   The minimum differential pressure that can trigger an insight
Threshold – Ventilation Impact Trigger %   The minimum ventilation impact that can trigger an insight
Threshold – Urgency Score Trigger %   The minimum urgency score that can trigger an insight
Threshold – DP Above Average %   The minimum differential pressure that can trigger an insight

Notes

Default Thresholds:

  • Threshold – DP Above Average [%]: 20
  • Threshold – Ventilation Impact Trigger [%]: 14
  • Threshold – Urgency Score Trigger [%]: 40
  • Threshold – Max DP Above Range (Urgency Score @ 100) [%]: 100
