 |
| |
|
| |
| Obsolete components should be replaced
with better, newer technology. Moreover ACs in general
have become more energy efficient over last year
or so. Hence, it does payoff to upgrade your airconditioning
system. |

|
| |
| Q:
Is it important to have a service/maintenance contract
for my AC? |
| |
| Your machine needs regular checks
to ensure its proper working condition. An Annual
Maintenance Contract with the company or dealer
is ideal, as a trained person can conduct checks
for any invisible faults or detect problems before
they become irrevocable. |

| |
| Q:
In a hotel/restaurant/kitchen there are food smells inside
the premises; is there a way to get rid of these? |
| |
| For areas like Hotels/Restaurants/Bars/Kitchens,
air-conditioners, which give out fresh air like
Packaged Units/ Ducted Splits, should be used. |
|
| |
|
| |
| Q:
And what about rooms full of smokers? |
| |
| Smoke being heavier than air tends
to stay within the air-conditioned areas. The absence
of fresh air to dilute smoke levels could also result
in this. Hence, use Packaged Units/ Splits, which
can handle fresh air and also ensure higher velocity
of supply air in the room to remove the haze. |

|
| |
| Q:
How to reduce my operational costs? |
| |
| Specify energy efficient systems
like Scrolls, Centrifugals. Ask for details of part
load performance. AC Systems are designed for peak
loads, which occur only for 2% or so of the time.
How the AC works during part loads is important.
Use multiple circuits wherever possible for better
part load performance. |

| Q:
What use is a sun film of? |
| |
| Sun film reduces heat entry through
glass. Using good a sun film can cut heat entry
by a good 70%. |
|
| |
|
| |
| Q:
Do computers affect the heat load? |
| |
| Yes! Each computer consumes about
300 Watts per hour and does add to the heat of the
room. The heat generated from 10 computers needs
1 tonne of air conditioning to keep the room comfortable. |
|
| |
|
| |
| Q:
Do lights add to the heat in a room? |
| |
| Yes. Every light adds 40 to 60 watts
of heat. 30 bulbs need 0.5 tonnes of air-conditioning
just to compensate for the heat they create. Tubelights
emit much less heat and you could put almost 100
tubelights and yet require only 0.5 tonnes of air
conditioning. |
|
| |
|
| |
| Q:
Which components in an air-conditioner consume electrical
power? |
| |
Almost 70-90% of the total power
consumption of a refrigerator is attributed to the
compressor. The evaporative fans, condensers, blowers,
water-pumps all require power but much less comparatively.
Conservation of energy certainly saves us money,
but it is also a duty, which we owe to our generation
and the next. To have your AC work efficiently,
these steps should be followed like a mantra. |
|

|
| |
| Q:
How safe is it to have pantry within the air-conditioned
space? |
| |
| Bad idea. Placing pantry within the
airconditioned space will lead to higher electricity
bills as more the heat generated, more the air-conditioning
required. And if there are stoves, there is a lot
of heat. But if you have an office pantry with a
microwave oven and a small electric kettle, it should
be OK. Keep the refrigerator away from the air-conditioned
space. |

|
| |
| Q:
Should I buy a Split AC or a Window AC? |
| |
| A room airconditioner is ideal for
rooms upto 200 sq.ft when one of the walls is exposed
to the outside. If there are no exposed walls a
Split AC is the only option. In addition, in a Split
AC the compressor is kept outside and hence, noise
levels are lower. |
|
| |
|
| |
| Q:
Do I need 3 phase supply if I have to buy an AC for my
house? |
| |
| Window ACs and Mini Split ACs work
on single phase. However, it is better to have a
3 phase supply and distribute the other loads like
Geysers, washing machines, pumps and lights in the
other 2 phases. |
|
| |
|
| |
| Q:
How can I reduce heat input into my room? |
| |
Providing a false ceiling (especially
for Room Airconditioners/ Multi-split Airconditioners)
reduces the volume to be cooled. Also, providing
curtains/ blinds /sun film on windows reduces
heat input into the room. In addition, insulating
the ceiling which is exposed to the sun with 50
mm thermocole drastically reduces heat input into
the room. |
|
| |
|
| |
| Q:
Do I have to necessarily buy a Voltage Stabilizer when
I buy an AC? |
| |
| The compressor which is the most
critical component in the AC works between 190 to
240 V. With voltages in most parts of our Country
going well below 190 V, we recommend using a Voltage
Stabilizer. |
|
| |
|
| |
| Q:
What is the ideal location for a Window AC? |
| |
At a height of 5 feet behind you.
Ensure that the AC air from the airconditioner
does not hit you directly. |
