Using heat pipe heat exchangers for reducing energy consumption of treating ventilation air in an operating theatre in a tropical climate: a simplified model

For that study, the software package TRNSYS (transient systems simulation program) has been applied to estimate the energy consumption of a typical operating theatre in a tropical climate (Malaysia). For the simulation, typical meteorological year (TMY) data for the Kuala Lumpur area (Malaysia), and an operating theatre located in the University of Malaya Medical Centre (UMMC)(Kuala Lumpur), are used. Simulations and results are presented.The current HVAC system could be improved with heat pipe heat exchangers (HPHXs). In tropical HVAC systems, a double HPHX system should be applied for the reduction of energy consumption and dehumidification enhancement.
