Charge Inventory

Pro

Refrigerant charge totals with PSM, RMP, EPCRA, and RCL checks.

Overview

Charge Inventory builds the system refrigerant inventory component by component — vessels, heat exchangers, piping — using saturation properties at each component’s operating state and editable liquid-fraction assumptions that follow common PSM/RMP charge-estimate practice. The total is checked against the federal thresholds that drive compliance scope, plus the ASHRAE 34 refrigerant concentration limit for the machinery room, and comes out as a report ready for review.

Key features

• Component-by-component inventory with per-row liquid-fraction assumptions
• Saturation properties (CoolProp) at each component’s operating condition
• Federal threshold checks: CERCLA RQ, EPCRA §302 TPQ, OSHA PSM (29 CFR 1910.119), EPA RMP (40 CFR 68)
• ASHRAE 34 RCL check — machinery-room concentration vs the occupied-space limit
• Handles halocarbons and CO2 too (no federal quantity trigger; RCL rules still apply)
• Resources tab with the RCL table, threshold citations, and estimate guidance
• Compliance report view for documentation

How to use it

1. 1

   Click Charge Inv. on the RIME ribbon (Refrigeration panel).

2. 2

   Add components with their volumes and operating states; adjust liquid fractions per row.

3. 3

   Enter the machinery-room volume to include the RCL concentration check.

4. 4

   Open the Report view — thresholds, verdicts, and the total inventory in one place.
