Ventilation and air conditioning system design of nuclear medicine building in a general hospital
Taking the nuclear medicine building of a certain comprehensive hospital as an example,this paper introduces the design of the ventilation and air conditioning system of the nuclear medicine building.Based on the characteristics of the hospital's nuclear medicine discipline,it is necessary to determine the specific equipment situation with the owner in the early stage of design to determine the suitable capacity configuration of the air conditioning system and the reserved civil engineering conditions;Radiopharmaceuticals and other diagnostic and therapeutic methods in the nuclear medicine department have strict requirements for environmental impact and prevention of radiation spread.Such places should be divided into different air conditioning and ventilation systems according to the control and supervision areas.It is recommended to set up separate exhaust systems or exhaust branches for high radiation areas within the supervision areas to meet the flow direction from low radiation areas to high radiation areas,and to meet the requirements of air flow direction and pressure control.
