Thermal Comfort In Hospital Operating Room

can be accomplished with 18 beds resulting in similar average performance as the current system. Ahmed Abdulelah Salim [25] studied two and three dimensional analysis for thermal comfort in a hospital operating room. Model of room consist of a patient lying on an operating room table, four surgical staff members standing around, and surgical lights above the patient. Cold clean air was supplied to the room through high sidewall grilles and from ceiling diffuser and exhausted through low sidewall grilles on the opposite and same wall. Steady state heat and mass transfer in the operating room was replicated by engaging computational fluid dynamics (FLUENT V.6.3) modeling approach. The results showed that an increasing in the ACH means increasing in air velocity and then decreasing

[27] studied a three-dimensional analysis for thermal comfort in a hospital operating room. room model contains a patient lying on an operating table, four surgical staff members standing around, and surgical lights above the patient. Cold clean air was supplied to the room through the ceiling and exhausted through low sidewall grills sustaining 20 ACH private the room. The steady-state heat and mass transfer in the room are simulated by employing computational fluid dynamics modeling approach. It was explored the effects of door opening on thermal comfort. The air was decreased on the upper limbs of the patient's body till door was opened 90o but further opening reverses the situation, mean age of air increased slightly on staff upper limbs but increases obviously on their lower limbs. These causes contradict in thermal sensation. The gradual door opening causes an increase in the mean age of the air on the lower limbs of patient and staff member relative to the upper limbs which contradicts comfort conditions and the gradual door opening causes hot and humid zones to propagate inside the room which deviates from the desirable thermal
