Evaluation of mechanical dehumidification concepts. 1.

Author(s) : TARAS M. F.

Summary

In recent years, humidity concerns have gained increasing attention in the air conditioning industry. In part, this increased attention is the result of high indoor air quality standards and newly introduced legislation and industry regulations. Humidity concerns have become even more visible since the introduction of alternate refrigerants with superior thermo-physical properties that may adversely affect system dehumidification capability. Although various dehumidification concepts have found their way into standard equipment offerings, the choice of the system type and configuration is not obvious and entails detailed evaluation of multiple characteristics. This paper analyzes various mechanical reheat/dehumidification concepts and highlights their advantages and drawbacks. The conclusion reached is that the reheat method utilizing a two-phase refrigerant mixture may provide a viable alternative to existing concepts in terms of application coverage and operational flexibility while preserving system functionality and reliability.
