We are currently seeking a number of skilled Mechanical Commissioning Engineers to join my clients growing team in Dublin. As a Mechanical Commissioning Engineer, you will play a crucial role in ensuring the effective operation and commissioning of HVAC equipment within data centers, contributing to the resilience and redundancy of critical systems.

HVAC/Mechanical Commissioning Responsibilities:

The HVAC/Mechanical Commissioning Engineer is responsible for testing and validating each component of HVAC/mechanical equipment used in data centers. The goal is to ensure that each piece operates in accordance with the building owner's design specifications and intent. Commissioning engineers then conduct comprehensive system tests to verify redundancy and resilience, aligning with the owner's design intent.

Experience in commissioning at least two of the following types of HVAC equipment is essential:

  • Chillers (Air or Water cooled) and associated Chilled Water System (CWS) distribution circuits.
  • Evaporative coolers.
  • Air Handler Units (AHU).
  • Computer Room Air Conditioner (CRAC) or Computer Room Air Handler (CRAH).
  • Pumps.
  • Variable Speed Drives (VSD)/Variable Frequency Drives (VFD).

Control Systems:

  • Experience in commissioning control systems is crucial.
  • Demonstrated ability to conduct functional testing of building control systems and integrate them with HVAC/mechanical equipment.
  • Familiarity with Direct Digital Control (DDC), Programmable Logic Controllers (PLC), and Building Management Systems (BMS).
  • Ability to interpret Functional Description or Sequence of Operation documents and ensure equipment and systems operate per specifications.

Testing and Validation:

  • Proven capability to conduct thorough testing, including:
  • Equipment local and remote Start & Stop.
  • Testing of all controls (e.g., temperature, humidity, pressure control PID loops).
  • Validation of failure modes.
  • Testing and verification of alarms locally and at BMS/SCADA graphics.
  • Validation of BMS graphics accuracy and correct representation of data points.
  • Setup of data trending and alarm handling.

Note: Candidates are not required to have PLC or BMS programming qualifications but must be able to read functional description documents or Sequence of Operation documents and understand the logic required to operate and test the equipment and systems. Candidates should demonstrate hands-on experience working with HVAC and mechanical equipment.

Educational Background:

  • Graduates in mechanical, refrigeration, HVAC, or controls/automation disciplines are welcome.
  • Apprenticeship-trained trade professionals with experience in mechanical/HVAC, refrigeration, and/or building controls are encouraged to apply.
