Roy, who also has a condominium in Gurgaon, sets the AC temperature at 27 degrees during the day and moves to degrees with a ceiling fan at low speed, if required, at night. Though the apartment has six ACs, only about are used at a time, but all are set at degrees, which means that the compressors are mostly not on or are on only intermittently," said Roy. A study in India shows that we are acclimatized to be comfortable at higher temperatures of up to 29 degrees, provided other thermal comfort parameters are met, said Mili Majumdar, managing director, Green Business Certification Institute GBCI and senior vice-president, US Green Building Council.
The perception of comfort is a cumulative of temperature, humidity and air velocity, she added. Not only that, you also end up conserving kWh energy in a year assuming your AC functions for eight months.
If you are setting the AC at low temperature and using a quilt or a blanket, it is not only unhealthy, it is also pure wastage of energy. Normal human body temperature is approximately degrees and putting your body through extreme high temperature on the outside and low temperature on the inside can affect your health.
So increase the temperature of your AC and keep it at moderate levels in order to not only conserve power, but also save on electricity bills.

There are many benefits of air-duct cleaning , including catching mold before it gets a hold on your system; keeping dust out of the air and off your clothes, furniture and surfaces; and improving the efficiency of your air-conditioning system.
Keep your home cool with these air conditioner maintenance tips to help prolong the life of your unit. Air conditioners are more sophisticated and energy efficient than ever. They come in a range of styles and sizes to suit any living situation, making it simple to find the best air conditioner for your home.

How to Choose an Energy-Efficient Air Conditioner There is possibly no modern invention more essential to comfortable living than air-conditioning. Select the information you need in order to find the best air conditioner and to maximize its energy efficiency:.
A too-large unit will cool the air but leave it damp and clammy. A too-small unit will have to work overtime to maintain the set temperature, driving up your energy bill. Air conditioner sizing is probably the single most important factor to consider. Central air systems are frequently even more flexible. Energy-saving setting: Another feature to look out for in the best air-conditioners is an energy-saving setting, which means that the unit will turn off not only the compressor but also the fan once your space has cooled off, thus conserving energy.
This certification means that this particular unit has met or exceeded higher efficiency standards than other similar models. Because these units are so adjustable, the energy-saving possibilities are amazing and allow you to really fine-tune your usage. How to choose an air conditioner size Properly sizing an air conditioner is important to ensure your home is cooled without using excess energy.
This lists the type of air conditioner and any key features. This is the make, model and size of the appliance. This is the average projected yearly cost of running the air conditioner.
Choosing Between Different Types of Air Conditioners Different types of air conditioners are better suited for different living spaces. Split air conditioners Split air-conditioning units usually come in two pieces—an exterior compressor and an interior fan system of some kind. Other types of air conditioners. Portable air conditioners Portable air-conditioning units look a lot like dehumidifiers.
When this has been attained, it adjusts the frequency to maintain the temperature without consuming excess power efficiently. It runs at full power to achieve the desired temperature; then it runs at part load to retain it, thereby using up less power than a non-inverter AC. An inverter air conditioner never turns off its compressor; instead, it adjusts the load according to the temperature of the room.
The continuous running of the compressor in an inverter AC means it can function for longer and it is also able to maintain the temperature of a room with more efficiency than regular air conditioners.
Non inverter air conditioners run on compressors which go on and off while maintaining the temperature of a room. The compressors run on full power to reach the desired temperature. When this is achieved, they go off until the temperature falls a few degrees, then they turn back on to get back the original temperature, on full power.
The non inverter air conditioners run on the AC system, which uses up more energy than the DC system. As shown above, the Inverter air condition run at a comfortable temperature by auto adjusting itself immediately after reaching the comfortable zone. Whenever it starts, it draws most of the power, and it runs on that power the temperature is achieved.
This results in higher consumption of power. Meanwhile, an inverter AC converts the input power of the AC to DC power to be able to adjust the frequency according to the load of the room. This makes it a more energy saving choice. A non inverter air conditioner has a fixed speed of air conditioning. It delivers a fixed amount of temperature to maintain the required room temperature.
This is not the same when using inverter air conditioning. An inverter air conditioner provides precise cooling in a very short time.
This can vary according to the time of day, size of the room, season, etc. In a non inverter air conditioner, when the set temperature is achieved, the compressor goes off.
It comes back on when the temperature falls by a few degrees. This causes fluctuations in room temperature. The inverter AC, on the other hand, has a compressor that adjusts its motor rotation speed to maintain the set temperature, ensuring a standard temperature. One of the top reasons to choose an inverter AC is the durability.
The compressor lasts longer than that of a non inverter air conditioner because of its smooth running without constant fluctuations. They are usually worth their cost. There are a few things you need to know about the electric energy consumption of Air conditioners.
Generally, energy star rating in BEE Bureau of energy efficiency , i. A 5-star rated non inverter AC of 0. A 5-star rated non inverter AC of 1 ton consumes units of power in hours while a 3-star rated inverter AC of the same capacity consumes units of power in hours. A 5-star rated non inverter AC of 2 ton consumes units of power in hours while a 3-star rated inverter AC of the same capacity consumes units of power in the same timeframe.
Based on this information, notice that the higher efficiency inverter ACs have a lower power consumption. In all, inverter ACs are the top choice for anyone looking to buy an air conditioner because they are more energy saving and also good for the environment. Energy efficiency is measured by SEER rating. Your SEER rating should depend on your location and environment.
Inverter ACs are the quietest ACs so far due to the constant and smooth working of the compressor. Having an AC with heating and dehumidification properties can save you a lot of time, work and money.
