Energy and Comfort Evaluation of Fresh Air-Based Hybrid Cooling System in Hot and Humid Climates

Maintaining mechanical ventilation has been identified as a potential strategy for reducing the risk of virus infections. However, in hot and humid climatic conditions, delivering fresh air to building comes at an energy cost could impact occupant comfort due persistent need simultaneous cooling dehumidification. In this paper, performance novel hybrid conditioning system that handles is studied. system, dehumidification accomplished by solid desiccant dehumidifier coupled with coil integrated tower existing chiller system. Using data available from operational system-level model developed validated study application climates. The found such effective sensible all types climates; thanks two-stage chilled water coils, respectively. thermal regions where climate relatively moderate ambient humidity. For tropical cities Darwin, Kuala Lumpur Bangkok, can provide comfortable temperatures, but faces challenges keeping humidity within zone. electrical coefficient (COP) higher than refrigerative systems. This also benefit over supply air, which entirely expected improve indoor environmental quality largely.
