Energy Efficiency Services Limited
Under the National Energy Efficient Fan Programme, EESL provides BEE 5 Star rated ceiling fans which are 30% more energy efficient than conventional fans. Fans will be sold for Rs. 1,150 per fan. EESL has distributed 6.2 lakh energy efficient fans under this scheme which will save 2.4 lakh kWh and Rs 8.2 lakh per day to the consumers. The price difference is Rs. 500 which is the primary reason for its low penetration, along with the lack of awareness. With the usage of these energy efficient fans it is estimated that consumer’s electricity bills will reduce by about Rs. 700-730 per year, and recover the extra cost in less than 2 years.
Ceiling protection switch
Ceiling protection switches are installed in secondary condensate drain pans in split system HVAC applications. The switch has a buoyant component that floats when the secondary condensate drain pan fills with water from the primary drain pan and shuts down the HVAC system to avoid overflowing. The ceiling protection switch is mainly used in applications where a piece of HVAC equipment is located in an attic or interior space where water damage is likely to occur. The switch does not guarantee the prevention of overflow, but may reduce the amount. Overflow water occurs when the condensate drain line becomes clogged restricting the flow of condensation from the interior to the exterior of the space. Overflow also occurs when an indoor HVAC coil becomes frozen, which when thaws creates excess water.
