refrigeration system documentation
The Refrigeration System Documentation portion of the ARM program contains the information pertinent to the equipment in the process. This section outlines the location and use of all of the information pertaining to the Refrigeration System. This includes; Material Safety Data Sheets (MSDS), Refrigeration Flow Schematics, the ammonia charge (or maximum intended inventory), Refrigeration Plan Views, equipment lists, operating limits, ventilation system calculation, relief system calculation, operation and maintenance information and a listing of all of the ARM program documents including their location.
2a. Develop Refrigeration System Documentation Policy
Wagner-Meinert, LLC will develop a policy outlining the facilities policy for the development and maintenance of the Refrigeration System Documentation. This policy will then be reviewed with facility personnel and finalized before being turned over to facility employees for implementation.
2b. Maximum Intended Inventory Calculation
An Ammonia Inventory Calculation would be performed by Wagner-Meinert, LLC produced on our database, with individual ammonia charge listed for each piece of equipment and overall piping. Calculations will be made for liquid ammonia contained in; vessels, heat exchangers, pumps, evaporators, evaporative condensers, and piping. Additionally an allowance will be made for vapor in the system. This information would be stored in our database for use during the project.
In some instances system charging records will be compiled in addition to the maximum Intended Inventory Calculation.
2c. Develop / Verify Refrigeration System Flow Schematics
Wagner-Meinert, LLC will provide engineering labor to field verify the existing flow schematics, reviewing valves, pipe sizes, and direction of flow for the ammonia refrigeration piping.
In some cases, insulation will be “punched” to determine pipe size. In most instances, we will be relying on pipe size information from the existing schematics and from facility personnel.
Following the field survey, our CAD group will then update the existing Flow Schematics utilizing Wagner-Meinert, LLC drafting standards. During this update, our engineers will work with our CAD designers to answer any questions they may have. Additionally our engineers will proof the drawings when the CAD department is finished with the revisions.
Wagner-Meinert, LLC personnel will then assign (on the flow schematic) a valve number to each isolation, pumpout, control, or check valve. Gauge or pumpout valves installed on the bonnets of control valves will not be numbered. Additionally strainers bolted to control valves will not be numbered. Strainers installed independently of controls valve will be assigned a number.
Valve numbers will be consecutively numbered beginning with valve number V-001.
2d. Develop / Verify Refrigeration System Plan Views
Wagner-Meinert, LLC will provide engineering labor to locate the refrigeration equipment and large refrigeration piping on the existing Refrigeration system Plan Views. We will need an existing floor plan for your facility approximately two weeks prior to the site work. If these do not exist, Wagner-Meinert, LLC can develop them for an additional fee.

2e. Develop Refrigeration Equipment List
Wagner-Meinert, LLC will gather equipment information for the refrigeration system. This information is vital to the operators, when ordering spare parts, or trouble shooting the system. This information is also reviewed during annual inspections.
This information would be stored in our database for use during the project. Printouts containing this information would be stored in Volume II, Equipment Information of the binder set. If electronic copies are required by the facility, scanned .PDF format files will be made available.
2f. Establish Operating Ranges
Each component (compressor, vessel, pump, evaporator, condenser, etc.) operates based on a set point. It is vital that Refrigeration System Operators understand the safe range that equipment in the system can operate at. Wagner-Meinert, LLC will gather information pertaining to operating ranges. In some cases this is done by interviewing operating personnel or consulting manufacturer’s information.
2g. Document Safety Systems
Each safety system should be documented. Safety systems include; Compressors safeties (cutouts and alarms), Condenser pump and fans controls, Vessel alarms and cutouts, Temperature alarms, etc. Wagner-Meinert, LLC will gather information pertaining to the safety systems. In some cases this is done by interviewing operating personnel or consulting manufacturer’s information.
2h. Develop the Relief System Capacity Calculation
Wagner-Meinert, LLC would provide labor to perform a relief system calculation based on the latest edition of ANSI / ASHRAE 15.
The Calculation would include equipment relief rates, node calculations, and header calculations.
The calculation would consist of a written report and referenced flow diagram. The flow diagram would serve to identify each node and its location in the system.
2i. Develop the Engine Room Ventilation System Capacity Calculation
The ventilation system serving the ammonia refrigeration engine room is an extremely important safety system; Wagner-Meinert, LLC personnel would perform a calculation of the system. This calculation would be done per current industry standards.
2j. Compile Operation and Maintenance Manuals
Wagner-Meinert, LLC would assemble an Operation and Maintenance Library covering the equipment in the Ammonia Refrigeration System. The manuals would be organized in the same order as the Equipment Information. Typical information includes:
1. Manufacturer’s Operation and Maintenance Information
2. Manufacturer’s spare parts lists
3. Cut sheets on hand and control valves
4. General Safety guideline from manufacturers (vessel safety, etc.)
When the manuals are complete, or as complete as possible, two sets will be produced and delivered to the facility as “Volume V - Operation and Maintenance Information”.
2k. Acquire manufacturer’s data reports and Certified Drawings for vessels
Wagner-Meinert, LLC would attempt to acquire manufacturer’s Data Reports and Certified Drawings. In some instances this information is no longer available. If information is not available, this will be noted.
When the information is compiled, two sets will be produced and delivered to the facility as to be incorporated into “Volume V - Operation and Maintenance Information”.
2l. Develop a Master Document List
Wagner-Meinert, LLC will develop a document listing all of the documents in the Ammonia Refrigeration Management Program. This document will then be reviewed with facility personnel and finalized before being turned over to facility employees for use.
