Lighting Turn off the lights when not in use Take advantage of daylight by using light-colored, loose-weave curtains on your windows to allow daylight to penetrate the room. Also, decorate with lighter colors that reflect daylight De-dust lighting fixtures to maintain illumination Use task lighting; instead of brightly lighting an entire room, focus the light where you need it Compact fluorescent bulbs are four times more energy efficient than incandescent bulbs and provide the same lighting Use electronic chokes in place of conventional copper chokes Fans Replace conventional regulators with electronic regulators for ceiling fans Install exhaust fans at a higher elevation than ceiling fans Electric iron Select iron boxes with automatic temperature cutoff Use appropriate regulator position for ironing Do not put more water on clothes while ironing Do not iron wet clothes Kitchen Appliances Mixers ·         Avoid dry grinding in your food processors ( mixers and grinders) as it takes longer time than liquid grinding Microwaves ovens ·         Consumes 50 % less energy than conventional electric / gas stoves ·         Do not bake large food items ·         Unless you're baking breads or pastries, you may not even need to preheat ·         Don't open the oven door too often to check food condition as each opening leads to a temperature drop of 25°C Electric stove ·         Turn off electric stoves several minutes before the specified cooking time ·         Use flat-bottomed pans that make full contact with the cooking coil Gas stove ·         When cooking on a gas burner, use moderate flame settings to conserve LPG ·         Remember that a blue flame means your gas stove is operating efficiently ·         Yellowish flame is an indicator that the burner needs cleaning ·         Use pressure cookers as much as possible ·         Use lids to cover the pans while cooking ·         Bring items taken out of refrigerators (like vegetables, milk etc) to room temperature before placing on the gas stove for heating Use Solar Water Heater – a good replacement for a electric water heater Electronic Devices Do not switch on the power when TV and Audio Systems are not in use i.e. idle operation leads to an energy loss of 10 watts/device Computers Turn off your home office equipment when not in use. A computer that runs 24 hours a day, for instance, uses - more power than an energy-efficient refrigerator. If your computer must be left on, turn off the monitor; this device alone uses more than half the system's energy. Setting computers, monitors, and copiers to use sleep-mode when not in use helps cut energy costs by approximately 40%. Battery chargers, such as those for laptops, cell phones and digital cameras, draw power whenever they are plugged in and are very inefficient. Pull the plug and save. Screen savers save computer screens, not energy. Start-ups and shutdowns do not use any extra energy, nor are they hard on your computer components. In fact, shutting computers down when you are finished using them actually reduces system wear - and saves energy Refrigerator Regularly defrost manual-defrost refrigerators and freezers; frost buildup increases the amount of energy needed to keep the motor running. Leave enough space between your refrigerator and the walls so that air can easily circulate around the refrigerator Don't keep your refrigerator or freezer too cold. Make sure your refrigerator door seals are airtight Cover liquids and wrap foods stored in the refrigerator. Uncovered foods release moisture and make the compressor work harder. Do not open the doors of the refrigerators frequently Don't leave the fridge door open for longer than necessary, as cold air will escape. Use smaller cabinets for storing frequently used items Avoid putting hot or warm food straight into the fridge Washing machines Always wash only with full loads Use optimal quantity of water Use timer facility to save energy Use the correct amount of detergent Use hot water only for very dirty clothes Always use cold water in the rinse cycle Prefer natural drying over electric dryers Air Conditioners Prefer air conditioners having automatic temperature cut off Keep regulators at “low cool” position Operate the ceiling fan in conjunction with your window air conditioner to spread the cooled air more effectively throughout the room and operate the air conditioner at higher temperature Seal the doors and windows properly Leave enough space between your air conditioner and the walls to allow better air circulation A roof garden can reduce the load on Air Conditioner Use windows with sun films/curtains Set your thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower will be energy consumption. Don't set your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling. Don't place lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary. Plant trees or shrubs to shade air-conditioning units but not to block the airflow. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun

ONIDA the pioneer of Television in India wishes all the viewer happy World Television Day

World Television Day will be observed on November 21 (Monday) across the globe including India highlighting the importance of television media in promoting awareness about important issues and events.

Different public and private institutions will observe the day through arranging discussion programmes and interactive sessions regarding development of electronic media in India.

World TV Day is marked every year to revive the endeavours of governments, organizations and individuals toward advancement of electronic media.

Electronic media has become a major source of information as well as entertainment for the public as they get pictorial footage of different happenings through this mode of communication.

The United Nations (UN) acknowledges that television can be used to educate many people about the world, its issues and real stories that happen on the planet.

Television is one of the most influential forms of media for communication and information dissemination. It is used to broadcast freedom of expressions and to increase cultural diversity.

The UN realized that television played a major role in presenting global issues affecting people and this needed to be addressed.

On December 17, 1996, the UN General Assembly proclaimed November 21 as World Television Day to commemorate the date on which the first World Television Forum was held earlier that year.

Some tips for washing machine users

1. Don't put more number of clothes than the specified number in your user manual. If you put more clothes, it may not wash the clothes properly as there will be no space for rotation and spin.

2. Nowadays seperate powders for washing machine from all the popular brands like RIN,Ariel,Surf etc are available.Use it instead of normal washing powders.

3. Never put silk sarees or delicate clothes in washing machine.Instead wash it by hand or give it for laundry.

4. Don't put the colour clothes and white clothes together in the washing machine unless you are very sure that the colour wont come out from the clothes.

5. Clean the dust collector bag in the washing machine frequently.

6. If your washing machine has got the option for cleaning the tub, do it atleast once in a month.

7. While putting shirts, handwash the shirt's collar before putting it to washing machine as most of the machines are not removing these kind of stains whatever detergent we use.

8. Keep the warranty card and customer care number of your washing machine always in hand in case of any problem. Normally washing machines come with 2 years warranty.

9. Don't put woolen clothes like socks in the washing machine as the threads may came out. 

10. Don't use washing machine for just 2 or 3 clothes. Instead you can wash that by hand.

Air Conditioner buying tips

Air Conditioner – an inexpensive luxury :
Now it has become easy to purchase Air Conditioner, a ‘luxurious’ item, for a common man due to several reasons like:

• Lowered price of equipment due to technical advancement
• AC s are made energy efficient, lighter in weight with no or less noisy
• Installation of Air Conditioner is no longer a tedious job
• Maintenance cost of Air Conditioner is much lower now
• A comparative study of brands, prices and efficiency can be done online easily

Types of Air Conditioner:
Air Conditioners are available in many models like Window AC, Split AC, Cassette AC and floor standing AC. There price vary with their type, size, ability to provide comfort and features. Usually Window AC or Split AC is in use in India. The type of AC to be chosen also depends on the place of its installation.Size of Air Conditioner: Split Air Conditioners: Split air conditioners are also available in various sizes like 0.75ton, 1ton, 1.5ton 2ton etc. The size of AC should be according to the size of room where AC is to be installed. It is suitable to install a 1ton AC in the room of size 12ftx12ft or so. A smaller room will need the smaller AC and the bigger one will need accordingly a bigger AC.

Offers more flexibility on where to locate the outside component than wall models

• Can cool open-plan areas well
• Very quiet operation
• Attractive and aesthetic designs
• Good air distribution for ACs of same size

Wall or window model Air Conditioners: Wall or window models can be installed in a window or an external wall.

• Can cool single rooms well
• Smaller units can be plugged into existing power points
• Single Unit
• Require lesser upfront cost as installation is simple

Power efficiency of the Air Conditioner:
In today’s expensive power situations, electrical equipment should be power efficient. It is declared by the manufacturing companies by displaying its energy efficiency rating provided by BEE. Though an equipment having 5/5 (5 star) rating is the most efficient one but AC is rarely found in this rating. Air Conditioners with 4star or 3star rating are considered to best.
Cooling Capacity:
The cooling capacity defines the price of air conditioners. Most air conditioners are rated in BTU per hour (British thermal unit) or by tonnage. One ton is equal to 12,000 BTU per hour. The cooling capacity that you need would depend on factors.
Average ambient temperature:
Higher the average temperature of the outside air in the area where your house is located, the more will be the cooling capacity required.
Size of the room:
The cooling capacity required is proportional to the area of the room you wish to cool.
Number of people present:
The cooling capacity of an air conditioner also depends on the number of people present in the room. The more the people present, the higher will be the capacity required.
Exposure:
Direct exposure of any of the walls of your room to sunlight would lead to higher requirement in cooling capacity.
Proximity of your room to kitchen:
If the room is nearer to the kitchen the cooling capacity required would be higher.
The tonnage of the AC can be selected based on the chart below: 

Rooms Size (Sq ft)	Tonnage Capacity
Up to 90 sq ft	0.8 Ton
Up to 120 sq ft	1.0 Ton
Up to 180 sq ft	1.5 Ton
Up to 220 sq ft	2.0 Ton

Types of Compressors

The compressor is the air conditioner's most important component and is often called the heart of the refrigeration system. It helps in the cooling process, by circulating the refrigerant through all the refrigeration parts. There are three types of compressors - reciprocating, rotary and scroll either of which can be used in split ACs.

1. Reciprocating compressor: It compresses the air by sliding the piston over the cylinder. Air conditioners fitted with a reciprocating compressor are generally less expensive and not as efficient or silent as the ones fitted with a rotary compressor. These are good for high duty cycles e.g. with higher capacity cooling ACs which need to be run for longer times.
2. Rotary compressor: This is a superior type of a compressor over the conventional reciprocating type. It compresses air by centrifugal action of high-speed impeller in a confined space. This method reduces the loss in pressure of the refrigerator gas. Rotary compressors are more compact, operate quietly, built for continuous operation and typically see less maintenance. The down side is the initial costs are higher. For less than 3 ton these are good options as they don't need high duty cycle and have better energy ratings. Rotary technology, though dominant in the Asian market for close to three decades due to its low cost, is new to India.
3. Scroll compressor: Scroll compressors have a wide operating voltage, economical running and low sound and vibration as compared to reciprocating and rotary compressors. Scroll compressors are generally available in ACs with cooling capacity above 2.5 tonnes. Rotary and Scroll compressors are not repairable once the failure occurs out of warranty period. Reciprocating compressors are reparable - mostly by respective compressor manufacturers in India.

AC Installation: 

• Make sure that you install the unit in an area that provides good ventilation. The air conditioner must not be blocked by any obstacle affecting the air flow near the air inlet and air outlet.
• Make sure that you install the unit in an area which can endure the weight and vibration of the unit.
• Make sure that you install the unit away from heat or vapor.
• Make sure that you install the unit in an area where the cold air can evenly spread in a room.
• Make sure that you install the unit in an area which provides easy drainage for condensed water.
• Make sure that you install the unit in an area not exposed to rain or direct sunlight. (Install a separate sunblind if exposed to direct sunlight.)

Do not install the unit in an area subjected to noise or vibration amplification which may affect your neighbour.

Microwave Cooking Tips

Planning to cook in Microwave, here are some of the tips, which can make your microwave cooking experience much better.

Even cooking

o    For cut vegetables make sure pieces are of equal size for equal cooking.

o    If you are cooking an assortment of vegetables, arrange large or tougher vegetables (carrots, cauliflower, broccoli etc.) toward the outside of the plate and small or tender ones (peas, mushrooms, capsicum etc.) in the center so they finish cooking at the same time.

o    Never pile food one on top of the other. In a microwave food always cooks evenly when spaced apart.

o    Turning is necessary to ensure even distribution of microwaves through the food. Especially food such as large potatoes and cauliflower need to be turned over during cooking. 

o    Round dishes give more even cooking results than squares or rectangles.

o    Ring shaped dishes are infact the best for cooking foods which cannot be stirred during microwave cooking. Improvise a ring shaped bowl by placing a small round bowl in the center of a large round dish. 

o    An omelet is best cooked at 50% (medium). If cooked at 100% (high) the edges may be done before the center and become leathery by the time the whole omelet is done.

            Standing time

• Food continues to cook when removed from the microwave cooker, by the heat generated within it. So always take into account standing time. Large or dense vegetables and fruit need standing time rather than more microwave time.
• If the food has been cooked with a cover leave it covered for the standing time. If it was cooked uncovered add a loose covering of foil to retain the heat.

Covering

• A cover holds in the steam to tenderize the food, keep it moist and shorten cooking time. 
• A tight cover is ideal for foods that have little or no added water, like when steaming vegetables. Use a dish with a tight lid or cover with cling film. 
• For foods cooked in liquid, or which create a great deal of juice, make a gap in the cling film cover by rolling back one edge. This allows excess moisture to escape. Or use special microwave lids, which have slits in them.
• Cover the dish with tissue paper while preparing "temper" or frying seeds like cumin, mustard etc. The tissue paper retains the seeds while allowing the moisture to escape.
• While reheating patties, kachori or mathri, place absorbent kitchen paper underneath to prevent them from turning soggy. Absorbent paper stops fat splattering and absorbs excess moisture.
• Not all cling films are micro-safe. If you are going to use cling film in the microwave be sure that it is marked as micro-safe.

Dos & Don'ts 

• Use a fork to pierce or prick whole vegetables, like potatoes and squash, which are cooked in their skins to allow excess steam to escape. If this is not done steam will build up inside, causing the skin to burst.
• Avoid using alcohol in puddings, which have to be microcooked, since it may catch fire.
• Season vegetables with salt after cooking them in microwave. Salting before hand could leave brown spots.
• You cannot fry in the microwave, as cooking fat in large quantities is dangerous. 
• When cooking rice in the microwave don't add all the water at one go, as it will boil over. 
• Milk based foods tend to boil over so use a larger and deeper container.
• Keep half a glass of water next to the dish while cooking too small a quantity of food.
• Increase microwave time in the same ratio as the amount of food to be cooked.
• Always start off with the shortest cooking time listed in the recipe, this way vegetables will not be overcooked. You can always cook it for some more time if required.

Micro benefits

• Melting chocolate in a microwave is so simple-it does away with the need for a double boiler. Microwave it at 50% (medium) for 2 ½ minutes.
• Warming oranges for 1-2 minutes produces more juice when squeezed.
• Microwave is very useful for steaming green leafy vegetables like spinach. 
• Clarify butter by heating cream (approx. 250 gm) on Micro 60 for 16 minutes.
• Increase shelf life of Sooji, Dalia, Idli rawa and other nuts and pulses by microwaving them on Micro high for 2-3 minutes (approx. 500 gm) This helps remove the moisture from these food items thus increasing their shelf life, especially in damp weather conditions.
• It is much easier to make sauces for Continental food in the Microwave, doing away with the endless stirring. Remember to cook the sauces on medium or medium low.
• To effortlessly remove a coconut from its shell, heat it on Micro high for 3 to 4 minutes.
• Blanch almonds by microwaving them with water for 3 minutes.
• 'Boil' potatoes in a jiffy. Microwave them in a polythene bag. For 4 potatoes microwave for 5 minutes. 
• Sterilize jars for storing homemade jams and pickles.
• 'Cook' your dishcloth in the microwave oven for 60 seconds to eliminate disease-causing microorganisms.

To use a conventional recipe in a microwave keep in mind the following points-
For curries, stews, etc.

• Use less water as there is less evaporation in the microwave.
• Start with 2/3rd of the water given in the conventional recipe, than add more if required.
• Cook on Micro High for about 5 minutes to bring to a boil and then simmer on lower power.
  For steaming
• Remember to cover
  Baking
• Don't cover
• Remember there will be no browning, so to get a better look try using cocoa in the recipe.
• Don't beat too much otherwise the cake will collapse in the microwave. 
• Infact a cake in the microwave rises higher than in a conventional oven.
• Add an extra 2 tbsp (approx.) of milk as the batter should be thinner than the ordinary batter. It should be of a pouring consistency. 
• Use powdered sugar otherwise the sugar will burn.
• Use round dishes.
• Fill dishes only half.
• Cakes require standing time.
• Microwave cakes taste best if eaten after a few hours.

Important facts about Air Conditioning

An air conditioning system can vary by the particular brand. That being said, here are some of the common components you will run into.

A true airconditioning system performs three basic functions. The one that would first occur to anyone entering an air conditioned room from the outside during the summer is air cooling. The lowering of the temperature of the air is one of the basic characteristics of an air conditioning system. Cooling capacity is measured, strangely enough, in a heating measurement, the BTU. A BTU is a British Thermal Unit which is the amount of energy needed to raise the temperature of one pound of water one degree of temperature measured in Fahrenheit.

The efficiency of an air conditioning unit can be measured by a standard known as SEER rating. SEER stands for Seasonal Energy Efficiency Rating. The minimum SEER rating has been 10, but recently was raised to 13 in January of 2006. The SEER is defined as the total annual BTU output of the unit defined by its energy input. The Federal Government and the Department of Energy have regulated the required SEER of all new air conditioning units in an attempt to reduce energy consumption.

High efficiency in cooling is more critical in climates where annual temperatures are higher and the demand for air conditioning is greater. It is actually worse to have a unit that is too large for the size of the building being cooled. An oversized unit not only costs more than it should, but runs efficiently. It will also not run long enough to properly dehumidify the air.

The ability to remove moisture from the ambient air is another characteristic of an air conditioner. Humidity is often as important to comfort as air temperature. High humidity also can contribute to health problems and contributes to mold growth in the duct work of the system and in the home itself. A regular refrigerant type air conditioner removes moisture from the air by condensation as the moist air passes over the cooling coils. The process is similar to what happens when you have a glass of cold liquid on a hot, humid day. Just as water will condense out of the air on the outside of the glass, it condenses on the tubing of the cooling coils. The condensed moisture drips off the pipes and is removed by a drain in the duct work.

Air filtering is the third characteristic of an air conditioner. Filtering is done by passing the air intake flow through a filter that removes dust and lint. Some filters can be used that remove microscopic pollutants from the air. The filters need to be changed on a frequent basis as a clogged filter greatly reduces the efficiency of the unit. Cooling, dehumidifying, and filtering are all characteristics of a good system, and produce air that is comfortable, dry, and clean.
