چکیده مقاله :
One of basic principles in designing treatment environments is to design air conditioning/ventilation system proportionate to environment. Essentially, appropriate air conditioner in treatment spaces must bear the following capabilities: providing healthy and clean air, reducing the concentration of pollutants produced in the atmosphere, emission of pollutants and impeding their spread in exterior space. Due to significance of the foregoing items in designing treatment spaces, in this research which has been conducted by descriptive-analytic method and using library studies, examination of hybrid ventilation system in treatment environments have been dealt with. Designing air conditioners in hospitals include ventilation design methods in form of natural/passive, mechanical, and hybrid ventilation systems. In this research, innovative design approach of hybrid ventilation system of hospitals have been introduced; having studied architecture of Iranian windtowers and greenhouse behavior of building façade and advantages and disadvantages of this system and superiority of the proposed system have been addressed. The system will be designed by using triple-walled shell (for the purpose of heating in winter season and airflow circulation in summer season) and cooling tower (plan design by viewing a vertical space in overall volume of the project and having direct access to AHU Rooms) A considerable advantage of this method is to reduce amount of energy consumption and subsequently decreased suction fan rotation period in cooling tower system as well as energy consumption reduction for heating air via fancoil.
