General Cooling Tips

• A. How do air coolers work?  

  When warm air is drawn into an Usha Air Cooler, it passes through a wet Honeycomb Cooling Media. As it passes through the honeycomb, water flowing over the honeycomb absorbs heat from the air causing the water to evaporate. This results in cooler, moisturized air. A powerful fan then propels the cool air into the room. The result is a constant low of fresh, moisturized, cool air while old and stale air is circulated out of the room through an open window or door.

  

• B. What is the difference between air coolers and air conditioners?  

  1. Air conditioners require a chemical cooling refrigerant and an energy-consuming compressor is used to absorb and condense hot air into cool air. The hot air must be released outside the room. The more complex composition of Air Conditioners also make them more expensive to purchase and they consume significantly higher electricity during use.
  2. Air coolers use the natural process of water evaporation to cool incoming warm air and use a powerful fan to expel the newly, cooled air. The temperature of dry air can drop significantly when liquid water transforms to water vaporous (through evaporation).

• C. What is the benefit of Usha air cooler ?  

  i. LOW PURCHASE COST

  Usha Evaporative Air Coolers are a budget-friendly cooling option because they are affordable to purchase and affordable to operate.

  ii. LOW ELECTRICITY CONSUMPTION

  Usha Evaporative Air Coolers consume very little electricity. Running an air cooler requires significantly less electricity than running an air conditioning unit, making them an attractive cooling medium in cities where electricity cost is high.

• D. How to increase affectivity of my Usha Air cooler?  

  i. Works Better In Low Humidity

  Evaporative Air Coolers are more effective in areas with maximum relative humidity of 60% or less. Warm, dry air is important for more effective evaporative cooling and the temperature decrease will be greater in drier environments because higher evaporation occurs when the humidity is low. Evaporative Air Coolers produce moisture and can be used to increase humidification in a room. They are ideal for maintaining a cool breeze and increase comfort in homes located in drier regions

  ii. Air Coolers require Cross Ventilation

  

  Evaporative Air Coolers should not be used in enclosed spaces. Doors and windows should be opened to allow free air flow. An Air Cooler works best when placed near an open window, drawing outside air and circulating it in the room before exiting via a window or door. The maximum cooling effect is felt when a person is near the flow of air coming out of the Air Cooler.

• E. What is honeycomb?  

  Honeycomb evaporative cooling pads in an air cooler are the special medium which hold the water for the air to pass through. The design of these pads resemble a honeycomb structure, thus the name. They give faster cooling, more durability and better efficiency as compared to the conventional Wood wool cooling pads. The honeycomb pad is made from an engineered thick cellulose paper which is chemically treated to resist deterioration, thus providing longer usage life. The cross fluted, unequal angle pad design is for the mixing of air and water for optimum cooling.

• F. What is Smart shield technology?  

  i. USHA Coolers now come with Smart Shield Technology powered by N9 Plastix. This technology ensures that your summers are fresh, safer and hygienic. In this technology the Water Tank is treated with an Anti-bacterial Additive which helps in reducing bacteria formation in the tank and limits algae growth.

  ii. How Does it Work?

  N9 Plastix is an unique composite. Silica present in the composite helps in the slow release of ions. These ions help in reducing bacteria formation and limits algae growth in the tank.

  The benefits:

  1. Safer: Anti- Bacteria – 99% reduction in bacteria growth on the water tank hence cooled air is much fresher and safer in comparison to other coolers with normal tank.

  2. Fresher: Algae Resistance – Limiting the Algae growth on the plastic tank that helps in keeping the cooler cleaner and reducing the associated malodour.

  3. Hygienic: Special Smart Shield Technology reduces the growth of microbes on plastic tank and thereby keeps the air fresh & Clean.

• G. How does the Float valve (Auto-fill) work?  

  Installed inside the cooler tank is a float valve, which is a device resembling a hollow ball. Every time the water comes below the minimum level, the water float valve will detect it and will start the water flow inside the tank, subject to a running water pipe being attached to the tank through the hose connector. In the same way it will also stop water in-flow when water reaches the maximum level. This is an automated process and will not require you to refill the water tank manually.
