ATCS-HVAC: Air conditioning chillers energy efficiency optimization

On-Line HVAC Chiller Tube Cleaning

ATCS-HVAC conserves the heat exchange efficiency of condenser tubes of water cooled air conditioning chillers by maintaining the condenser tubes free of fouling. Rubber balls are recirculated at set time intervals to capture deposits accumulated in the condenser tubes.

Fouling in the chiller’s condenser tubes is a costly problem

  • Energy consumption spikes: as little as 0.3mm of dirt in the chiller’s condenser tubes increases energy consumption by 10% or more..
  • Environment is affected: Greenhouse gases are released to the atmosphere.
  • Profits drop: expenses increase due to extra energy consumption and repeated tube cleaning.
  • Conventional tube cleaning cleaning methods are temporary, expensive, cumbersome and progressively inefficient.

Advantages of ATCS-HVAC over conventional systems

  • Cost-effective: maximizes chiller efficiency for multiplied savings in operation, manpower and energy – up to 25% savings in the chiller’s annual operation cost.
  • Environmentally safe: uses no chemicals, produces no hazardous waste.
  • Continual operation: works while the chiller is on.
  • Automatic: computer-timed cleaning with no need for intervention.
  • Reliable: high-performance parts.
  • Efficient: one ATCS-HVAC installation can handle an entire facility.
  • Measurable savings: reliably measure savings with installation of the optional Integrated Performance Tracker.

How ATCS Works

CQM’s ATCS is installed on the chiller’s condenser and keeps tubes clean without human intervention. The system periodically injects into the tubes sponge balls that are slightly larger in diameter then the tubes themselves. The natural pressure head pushes the balls through the tube, which is thus rubbed clean. The balls are then trapped in the outlet of the heat exchanger, where they are prepared for the next cleaning cycle.

Up to 25% electricity savings with automatica heat exchanger tube cleaning
Typical comercial installations take less than 25 man hours, and requires only 8 hours of process shutdown. Trapping units are available in a variety of shapes and flow configurations to accommodate piping routes design and available space for installation.
