HVLS stands for High volume low speed, HVLS fans are large diameter fans above 7 feet in diameter normally used for cooling or air circulation over large spaces. These Ceiling fans majorly finds application for large area like auditorium, indoor stadium, railway station, airport, public places, School, cafeteria, animal cooling etc Ceiling fans produces column …
Lighting load is significant for residential, commercial or industrial building or spaces. Windows enlarging and providing light passage for reducing day time lighting load is the best technique for solar light harvesting, while this option is suitable for only walls exposed to solar light and controlling lighting is also difficult. To solve this problem light …

What is RefrigerantA refrigerant is a substance or mixture, used in a refrigeration cycle. Generally, It undergoes phase transitions from a liquid to a gas and back again. Types of Refrigerant: 1. Primary Refrigerant:Primary refrigerant directly take part in refrigeration, Eg Freon ( R11, R22, R32, R407C, R134a etc), Ammonia, water. Theses refrigerants directly absorb …
Ceiling fans are most common household appliance after lighting, considering the power consumption in summer it has significant energy contribution for middle and lower middle class people. The power consumption in fans should not be ignored while considering energy planning. To promote energy efficiency in fans, Bureau of energy efficiency (BEE) in India has included …
Development of a country depends on some certain basic infrastructure pillars and one of those is the availability of quality and reliable power in the country. The country needs 24×7 continuous electricity supply to all customers, as well as consistency in sector service and customer participation. After the 2003 Electricity Act was enacted, Indian power …
Chiller performance depends on the various factors like condenser temperature, evaporation temperature, compressor loading, refrigerant quantity etc. One of the major factors which impact the chiller performance is condenser saturation temperature. Condenser saturation temperature depends on various factors like Variation in cooling water temperature. cooling water temperature depends upon performance of cooling tower and atmospheric …

Ensure correct utility for process: If a process is capable to run on 5 Deg C never use 1 Deg C Chilled water, lowering every 1 Deg C will increase power consumption from 2.5 to 4% in compressor power. During Design insure proper IPLV / NPLV selection : Chillers/ refrigeration system never operates on full …
Transformer efficiency is one of the areas which may help in reducing energy cost, Transformers are one of the most energy efficient equipment and its efficiency can go upto 99%,if operated in the best efficiency area. In transformers efficiency loss is subject to the loading of the transformer. Total loss LT can be easily calculated by LT = …
Area of Improvement: 350 TR Screw chiller, with refrigerant as R134a was in operation. Chiller inlet and outlet temperature was designed for 12 deg C and 7 Deg C. variation in cooling water temperature was from 22 deg C to 32 deg C. Cooling tower water treatment program was well maintained. Condenser cleaning procedure was …

In shell and tube heat exchanger, especially where the cooling media is cooling water, there is higher probability of fouling. Therefore periodic heat exchanger cleaning is required to improve the heat transfer of the heat exchanger. In general heat exchanger’s are cleaned either chemically or mechanically, both type of cleaning requires shutdown of the heat …
