The Ad­van­tages and Dis­ad­van­tages of an In­verter AC

Consumer Voice - - Inverter Air Conditione­rs -

Ad­van­tages

a) About 30 per cent to 50 per cent cheaper to run as it con­sumes less power com­pared to a con­ven­tional AC

b) No volt­age fluc­tu­a­tion caused by com­pres­sor

c) Main­tains con­stant room tem­per­a­ture

d) Ef­fi­cient cool­ing and heat­ing

e) Can be run on so­lar pan­els

f) Apart from sav­ings in monthly elec­tric­ity bill, there is huge sav­ings on fuel if run on backup gen­er­a­tor

g) The ad­di­tional price paid for an in­verter AC gets re­cov­ered in elec­tric­ity bills within a few months

h) Environmen­t-friendly due to the use of bet­ter re­frig­er­ants

i) Safe for house­hold wiring due to lower power con­sump­tion

j) Suit­able for large and small rooms

Dis­ad­van­tages

a) If room is not in­su­lated, power con­sump­tion in­creases and so does the elec­tric­ity bill

b) Ef­fi­ciency de­creases at noon if weather is ex­tremely hot (over 45 de­grees C)

c) Rel­a­tively ex­pen­sive re­pair and main­te­nance due to the ex­pen­sive ser­vice sup­port and the com­po­nents used

d) Mod­els too pow­er­ful for the room size may run fre­quent short cy­cles to achieve the target tem­per­a­ture. This can re­sult in the room get­ting too cold or too hot; in­ad­e­quate de­hu­mid­i­fi­ca­tion (that is, not dry­ing the air enough, mak­ing the room feel less com­fort­able); in­creased power us­age and run­ning costs; and wear and tear on the sys­tem e) Un­der­pow­ered mod­els may have to run more of­ten at max­i­mum out­put and dry the air too much

Keep Your Check­list Handy Noise

Check the air con­di­tioner’s noise lev­els; these can be found in the spec­i­fi­ca­tions. Some mod­els have a quiet mode for the in­door unit, and some­times the out­door unit too. This may re­duce the cool­ing/heat­ing power or air­flow, but will keep the air con­di­tioner run­ning at a very quiet level.

A noisy in­door unit may in­ter­fere with your ac­tiv­i­ties, con­ver­sa­tion, or sleep. A noisy out­door unit can dis­turb you or your neigh­bours.

Ca­pac­ity

The ca­pac­ity of the air con­di­tioner should be con­sid­ered de­pend­ing on the floor size of the room where it will be in­stalled. A rough mea­sure is that an area in the range of 120 ~140 sq. ft area will need a 1 ton AC, 150 ~180 sq. ft area will need 1.5 ton, and 180 ~240 sq. ft area will need 2 tons.

Star-rat­ing la­bels

Once you’ve worked out what ca­pac­ity you need, com­pare the star rat­ings of mod­els of sim­i­lar ca­pac­ity. The more the stars (from 1 star to 5 stars), the lower the run­ning costs and green­house gas emis­sions. Air con­di­tion­ers come with star-rated en­ergy-ef­fi­ciency rat­ings; these have been stan­dard­ised/im­ple­mented by the Bureau of En­ergy Ef­fi­ciency (BEE), Govern­ment of In­dia. There­fore, any AC with more stars will con­sume less elec­tric­ity than one with a lower star rat­ing.

Af­ter-sales ser­vices

Af­ter-sales ser­vice and other add-on fea­tures like war­ranty will cer­tainly be a plus for your pur­chase. Look for longer war­ranty and a ser­vice-ori­ented brand that has the ca­pa­bil­i­ties and good net­work to meet the ser­vic­ing need of your prod­uct.
