Hygiene evaluation of construction and design for central ventilation and air-conditioning systems in dining area of supermarket

Objective To prevent and control the health risk factors in central ventilation and air-conditioning systems in dining area of a supermarket.Methods The contents of hygienic checkup on the construction and design,field investigation on surroundings and risk factors inspection were carried out,data was collected and analyzed to evaluate based on hygienic standards.Results Reference standards for temperature parameters design was not correct on central ventilation and air-conditioning systems in dining area of the supermarket.Air conditioning refrigeration design didn’t meet summer cooling load requirements,and lacked purification and disinfection equipments before ventilator,which both fell short of health requirements.Environmental hazards monitoring indicators were in line with standards,adaptable to site designated construction for the construction projects.Conclusion In order to ensure environmental health safety in public places,it is suggested that services specialty of dining area of a supermarket should be entirely considered,and central ventilation and air-conditioning systems design should be optimized.
