HVAC

Industries: HVAC

Heating and ventilation are of utmost importance in both homes and office buildings. That’s why we employ the help of HVAC systems. Heating, Ventilation and Air Conditioning (HVAC) systems function to maintain the comfort and safety of building occupants. Heating and air conditioning components assist us by controlling indoor climate and proper airflow, ensuring that we neither freeze nor sweat. Health benefits of a well-maintained HVAC system come into play with the prevention of mold, which frequently thrives in warm, damp areas. We want to do our best to maximize efficiency.

Heat Exchangers in HVAC

Heat exchangers are essential part of any kind of HVAC system nowadays. Heat exchangers contribute substantially towards energy conservation and reduction in energy bills. The main function of a heat recovery system is to increase the energy efficiency by reducing energy consumption and also by reducing the cost of operating by transferring heat between two gases or fluids, thus reducing the energy bills.

The heat exchangers are the best known devices for this purpose. In heat exchangers, as the name suggests, there is a transfer of energy from one fluid to another. Both these fluids are physically separated and there is no direct contact between the fluids. The transfer of heat can be between steam and water, water and steam, refrigerant and water, refrigerant and air, water and water.

Heat Exchanger Failure Mechanism
  • Process corrosion
  • Process fouling
  • Steam/condensate corrosion
Three main areas for improvement to minimize future in-service tube failures.
  • Tube testing
  • Retubing strategy
  • Design improvements.
Tube Testing

Technologies for inspecting heat exchanger tubes are rapidly changing and continuously improving. Variance in test results depending on both the instrument and operator. The impact of human factors on non-destructive examination (NDE) performance is more prominent with the increased complexity and sophistication of today`s NDE techniques. Root cause analysis of some of the tube failures identified the need for reliable technicians and technologies.

APRIS provides solution to tube inspection problems with important advantages to HVAC industry by minimizing downtime and improving operational productivity.
