This project aims to study and design of refrigeration and air conditioning systems for sterile operating room. . In designing air conditioning for sterile operating rooms. A room no larger than 60 square meters and has a cooling load of not more than five tons of cooling (60,000 Btu / hr) that can control the amount of air circulation. Ventilation, temperature, humidity, air pressure and air filtration that meets performance requirements. In designing refrigeration systems conditioning aseptic will calculate Condenser coil, Evaporator coil, Reheat coil to determine the size of the pipe and rows of coils
from the calculation, the nozzle by air volume in 2650, we will. has a total area of Filter Filter 3.36 square mater 36.17square foot, but each has an area of 6.8 square foot must use HEPA six nozzle plate to come by at the air show in 2650 that the air supply HEPA 441.67 CFM per sheet cost pressure. 80 Pa drop across the filter design has a filter HEPA H13 6 plates will pressure drop 480 Pa or 1.927 in.wg Depth of coil 3 Row 3 row because it does not use the graphs 4 row without sprays. 6 fins / in. Total pressure Drop 2.375in.wg
Condensor Coil size 23x35 inch pipes Type L size red ½ inch hose to the back for a total of 28 rows of tubes, pipes, four rows
Evaporetor coil size 21x37 inch copper pipe. Type L 3/8 inch hose to return the total number of rows of tubes 14 tubes 12 in
a Reheat coil size 20.35x37.5 red square inch pipe size Type L ½ inch hose to the back for a total of 30 pipe rows. three rows of tubes are very close to the values entered in the program.
