THERMAL ENERGY STORAGE

Testing and Commissioning

From my personal experience out of Thermal Energy storage – Off peak Air-conditioning – Ice Storage Plants, in this day I shall present you the full story of Testing and Commissioning.

See below four steps:

1.     PRE-COMMISSIONING

2.     TESTING & COMMISSIONING

3.     PERFORMANCE TESTING

4.     OPTIMIZATION

 

PRE-COMMISSIONING

This is the period of completing the Design and that of budgeting and call for tender.

The Commissioning Provider is called for the Design Review, so there is always a time lag to reach the Tender Date.

Then, is Procurement phase, by the Contractor as well as the shop drawings in order to send Work orders.

The Commissioning Provider is called for examine the submittals whether they meet MEP specifications and drawings.

Next step is Installation by sub-contractors with the help of shop drawings and Foreman’s supervision.

The Commissioning Provider is called to oversee the installation and keep notes on pre-commissioning forms.

Flushing is a required process on all equipment as well as on all piping.

The Commissioning Provider is called again to check the process.

Project Management is an obligation of the Contractor together with Quality Assurance and Quantity Surveying.    

 

COMMISSIONING

Starts with the completion form of “READY FOR COMMISSIONING”, by the Contractor.

 The Commissioning Provider is called to check that Ice storage plant is completed, Construction Check lists and Point Lists are updated as well as the as built drawings are in hand.

Sequence of operations is clear to BAS provider and the BAS Architecture is updated.

Next step is Start up of all machinery by Manufacturer’s Service Team.

The Start-up Report is clear of every comment regards machinery performance failure.

The Commissioning Provider is called to verify Start-up procedures with help of Graphics Display of BAS.

Last important is signage of all |every machineries as well as every piping arrangement.

The Commissioning Provider is called to verify all signs in the plant room.

 

PERFORMANCE TESTING

In this step a full measurement is done on all flow rates, temperatures, current drawn, power input, etc

Calculations on EER are done on all cycles of Ice storage plant.

The Commissioning Provider is called to verify measurements and calculations.

 

OPTIMIZATION

Here we start with trending through BAS all ice storage cycles for 3 working days of the week, as well as non-working days.

We trend the Occupancy profile of the Building for 1 or 2 weeks.

We make minor changes in ice making time plan, in order to get best results.

Alternative Electricity tariffs are very important, to consider at this time.

Last and important is Operators Training as well as a 2-year Service Contract with Main Manufacturer and equipment provider.

The Commissioning Provider is called to verify this Optimization step.

Dear customer you could decide today to adopt THERMAL ENERGY STORAGE.

Yours, for business together.
