Frequently Asked Questions
1. What is an Inverter Air Conditioner? Is it more efficient than a conventional air Conditioner?
An Inverter Air Conditioner works on a variable speed compressor which does not switch on and off like regular Air Conditioners. Rather, depending on the heat load of the room it varies its speed & achieves the desired temperature with lesser power consumption. Thus, it is more efficient. Voltas All Star Inverter ACs are powered with Two Stage Steady Cool Inverter Compressor which provides two stage compression under two stage expansion. Hence, it is more efficient than a conventional Inverter compressor.
2. What is ISEER rating for Air Conditioners?
The Bureau of Energy Efficiency (BEE) has introduced a new star rating regime called Indian Seasonal Energy Efficiency Ratio (ISEER) starting from January 1, 2018 for all Air Conditioners. It factors in variance in higher temperatures and different climatic zones in India and rates Air Conditioners accordingly by. It measures energy efficiency of Air Conditioners based on a weighted average of the performance in outside temperatures.
3. What is the electrical consumption of an air conditioner per month?
Estimated Electrical Consumption = Input (kW) X No. of hours used X No. of days per month X Current Utility Rate.
4. What is the average life span of a room air conditioner?
The average life span of an air conditioner is 6 to 10 years. This depends on the installation process followed, hours of usage and annual maintenance of the product. This should be done by an authorized company technician.
5. What type of AC one should buy, Split or Window?
In terms of monetary value, split ACs are slightly more expensive as compared to window ACs. Also, since the outdoor & indoor unit are separated in case of split ACs, they are quieter in operation. From an aesthetics standpoint also, split ACs are better. Window ACs are preferred when we have installation constraints.
6. What tonnage of AC is ideal for my room?
The normal tonnage of an AC is 1, 1.5 or 2 ton. Bigger the room area, direct exposure of the roof to sun and more no of doors & windows would lead to higher tonnage capacity requirement for the AC.
7. What star rating of AC is ideal for my room?
More the no. of hours of usage of the AC, higher is the star rating requirement. Buying a higher star rated AC would help to lower the units of electricity consumption over a period of time. The star rating can range between 1,2,3,4 & 5 stars.
8. What is cool mode in an AC?
Ideal for comfort setting. Use of this mode is recommended when the outdoor temperature is 22 – 46°C.
9. What is dry mode in an AC?
Ideal for humid conditions & rainy season. Use of this mode is recommended for dehumidifying when room temperature is over 16°C.
10. What is fan mode in an AC?
Ideal for quick room air circulation. When using this mode the device would work as a simple air circulator. Use this function to dry the interior of cooling unit at the end of summer and at the beginning of season.
1. What is an Evaporative Air Cooler?
An Air Cooler works on the principle of evaporative cooling process. When warm air is drawn into the cooler, it passes through a wet Honeycomb/WoodWool Cooling Media. As it passes through, it mixes with the water held in the Honeycomb/WoodWool Cooling pads, causing the water to evaporate and lose heat, resulting in cool & moisturized air. A powerful fan then propels the cool air into the room (or outdoor area, if outdoors). The result is a constant flow of fresh, moisturized, cool air while old and stale air is circulated out of the room.
2. Why does evaporation cause lower temperature?
The temperature of dry air can drop significantly when liquid water transforms to water vapor (through evaporation). Water always has lesser temperature than air called dew point temperature. So, water evaporates by taking heat energy from warmer air which mixes with it & hence it results in temperature drop.
3. How is a room air cooler different from a fan?
Normal fans use fan blades to circulate air around the room without offering any cooling. Room Air coolers use the natural process of water evaporation to cool incoming hot air and use a powerful fan to evenly distribute newly cooled air. The temperature of dry air can drop significantly when liquid water transforms to water vapor (through evaporation).
4. What are honeycomb cooling pads and how are they different from conventional wood wool pads?
The honeycomb cooling pads are more durable and also provide uniform cooling. Moreover, they do not allow dirt & sediments to deposit on the pads. Hence, it gives cool & fresh air.
5. How do I select the right type of room air cooler (Personal, Desert, Window or Tower)?
Desert Cooler – if the room size is big (>250 sqft) and climate is dry & hot.
Window Cooler - if the room size is big (>250 sqft) and climate is dry & hot. The window cooler comes with a trolley which can be used under multiple applications.
Personal Cooler – If the room size is small (<150 sqft) and the climate is humid or temperate. It is mostly used for personal or spot cooling.
