 Posted by: mukund400 ® 05/10/2008, 15:50:35 Author Profile eMail author Edit SELECTION OF AC DEPENDS ON FOLLOWING CRITERIA 1.AREA OF THE ROOM 2.HEAT GENERATING APPLIANCES IN THAT ROOM. 3.NO OF PERSON GOING TO OCCUPY THAT ROOM.GENERALLY-1.O TONN IS USED IN 100 SQFT AREA.NOW I TAKE YOUR QUEST. I ASSUME HERE THAT YOUR ROOM AREA IS 150 SQFT WITH CEILING HEIGTH OF 12 FTS. ALSO U SAID THAT HEAT OF 26 KW WILL BE GENEARATE BY UR SYSTEM.THAN BTU=0.7XWATTSX3.5 (0.7 IS TAKEN BECOZ 26 KW WILL NOT BE FULLY CONVERTED TO HEAT SO I TAKE 70%)SO BTU=0.7X26000X3.5=63700 ALSO IF THERE ARE 6 PERSON THAN BTU=6X350=2100 AS AREA IS 150 SQFT THE NUMBER OF BTU REQ IS=18000 BTU(1.5 TONN)SO TOTAL BTU=63700+2100+18000=83800 NOW TOTAL TONN=BTU/12000=83800/12000=6.9 TONNNOW HP=0.8TON =0.8X6.9 =5.5THIS IS THE ANSWER.I HOPE U HAVE UNDERSTOOD.FOR ANY QUERIES FEEL FREE TO CONTACT
