Creativity
Interactive Air conditioner is a premium range air conditioner designed with the theme “Smart and energy efficient homes”. Product works on new-age Zigbee wireless technology. With its intelligent features like Trane mode, energy meter, Multi unit , hassle free control and home connectivity this air conditioner addresses the high degree of convenience, comfort & control and makes everyday living simple and intuitive. The product has an operating mode called ‘Trane mode’ which uses built-in, state of the art intelligence to maximize the comfort while keep the energy consumption at lower level. The Efficiency Meter on Interactive remote enables real time control of energy consumption without compromising on comfort. Unit assesses the weather outdoor, and accordingly sets an optimum indoor temperature and help in avoiding thermal shocks. Wireless technology brings convenience to the home user because they no longer have to point the remote control unit towards the AC. This technology allows the user to sit anywhere in his home and control up to 18 AC unit installed anywhere in the house. With home connectivity feature user can turn off Air conditioners with just click of ‘Away’ button on the lock while leaving home. ‘Home’ button on the lock switches on Air conditioners automatically.

Just by pressing a button on the Interactive Remote, one can lock door from anywhere in the house. The remote control unit displays easy to understand & actionable service alerts. The Trane AC has a multi bend evaporator coil which takes lesser space than a normal coil, therefore rendering an ultra slim look to the AC. Its exceptional concave profile helps in better air distribution and powerful cooling. There is no temperature display on the unit and hence clean & plain look resulting in discreet appearance and comfortable ambience. The general appearance of interactive remote control is characterized by a clearly organized interface and an altogether harmonious front design. Beauty and elegance of the product comes from a sense of simplicity and design consistency. The design of the interactive air conditioner is integrating state of the art intelligence at the same time establishing comfort, harmony and ecological commitment.
Design Challenges
To get home connectivity through Wireless Interaction of the Air conditioner with Remote control and Electronic lock was the most challenging task. Need to use various advanced manufacturing processes to develop slim AAA Battery operated remote control design. Thickness of the Remote control is 14mm which is one of the slimmest AAA Battery operated Air conditioner remote control available in India. User interface of remote control displaying lot more information compared to other remote controls and more feature set with minimum number of buttons on Remote was another challenging task.

Louver fins are made up of PVC. Colour of front panel, middle panel cover is Snow White Pantone 11-0601 TPX. Copper Tubing ensures long & trouble free life of AC due to usage of copper for condenser, evaporator & interconnecting pipes A full length barrier makes the body waterproof and thus protects electrical parts from rain water. It also reduces the possibility of short circuits Corrosion resistant screws & washers provide longer life & lower noise. Valve Protection cover protects valves against any impact during transportation, and also prevents them from dripping condensed water. Grooved Copper tubing & Coated Aluminum Fin improves heat exchange efficiency by lowering power consumption. Due to sound reduction jacket for compressor and screw free protection grills, the outdoor unit operates at a lower noise Remote control unit: Front housing of remote control unit is made up of Polycarbonate material. Screen on the front cover is of Transparent Black Polycarbonate (1.5 gm. of black colour additive per Kg. of transparent polycarbonate). Back housing and battery cover is made up of PC + ABS material. Colour of front cover, back cover and battery cover is Snow White Pantone 11-0601 TPX. Dome switches are used to get feel of gentle press. In order to backlight the keypad for better visibility at night, silicon based keypad is used with transparent polycarbonate button caps on it. Infrared window is made up of standard Indigo colored Transparent Polycarbonate. LCD glass is packaged with ABS frame and is secured with rubber film on top of it. Production method: Indoor air conditioner unit: Base chassis, middle frame, front panel is made up of HIPS and is injection molded. Unit that holds control panel is made up of Fire rated ABS is injection molded. Louver fins are made up of PVC and Injection molded. Copper tubing are welded together with interconnecting pipes and fins are assembled to it. Corrosion resistant screws & washers used for the assembly of the unit.
