1 Tr=12000 BTU=3024Kcal
To obsorv 3024 kCal Heat in Temp.diff Of 37(Amb)-23
(Required)=14 c It consumped 4 Hp Energy.
Then Amp=w/1.732*0.8*415 In 3 Phase
Energy Efficiency Ratio for AC:
•EER = cooling capacity / Power consumption (both in Watt)
•EER of 1 TR (about 3,514 W) capacity air conditioner
consuming power 1,500 W = 3,514/1500 = 2.34
•Star Rating System based on EER - 1-Star: 2.5, 2-Star:
2.7, 3-Star: 2.9, 4-Star: 3.1 and 5-Star: 3.3……………………for
 1 TR = 1500 W (Power Consumption- Including comp and fan
 1 TR = Thumb rule says it's 1.2kw to 1.5kw ..........
Depend on EER OR Star Rating
 1 TR = 3514 W (cooling capacity)
Hence approximate full load Current (I) is =
1500W /230V = 6.5 Amp ………for 1 Star Rating AC.
( Re: WHAT SHOULD BE THE RATING OF MCCB FOR 415V,3Ph,50KVAR
# 1 The capacitor current would be kvar x 1000 / (415 x
sqrt3). This would be 70a approx. The MCCB selected should
have *atleast 1.4 times this current i.e. 1.4 x 70= 98. So
you should choose at least 100 A mccb.)
regarding to this answer,i would like to know why the
current have to times 1.4 to get the right amphere for the
mccb.hows the formula to get the 1.4??tq
