ICAR-CIPHET, Ludhiana gives licensing on "High Volume Low Speed (HVLS) Fan" to Jagraon based Fan Company (M/s Chana Mechanical Engg.)
The technology is highly useful for providing cooling and comfort in cattle sheds, animal shelters, warehouses and other high ceiling buildings and structures
Ludhiana, 09 September 2019:
Ventilation of animal housing to remove moisture and odors and replacing them with fresh air is necessary for livestock productivity and also provides air movement that promotes cooling and improves air quality for confined animals. Achieving this with normal fans is expensive both in terms initial investment as well as operating costs. Also the air in shelter is stratified due to temperature gradients. Keeping in view the need, ICAR-CIPHET, Ludhiana has developed High Volume Low Speed (HVLS) fan. The technology wa jointly by developed by Dr. K. Narsaiah, Dr. Sandeep Mann, Dr. Yogesh Kumar and Mrs. Leena Kumari.
Elaborating more about the technology, Dr. K. Narsaiah said that the technology was highly useful for providing cooling and comfort in cattle sheds, animal shelters, warehouses and other high ceiling buildings and structures. HVLS fans are generally ceiling fans although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed." HVLS fan with custom designed large paddle type blades move the air as one large cylinder (less drag as less interface area). The flow is in laminar regime resulting less energy loss in friction. The secondary flow of the fan after hitting the floor would further cover additional area. In this way one HVLS fan can approximately give performance equivalent to 6 normal fans. The power required to run the fan at low speed is significantly less and results in low operational costs.
Mr. Karnail Singh Chana, Proprietor M/s Chana Mechanical Engg., Jagraon approached the institute for this technology. Awarding the license of the technology to entrepreneur on 09.09.2019, Dr. R.K. Singh Director (Acting), ICAR-CIPHET, Ludhiana remarked that this technology is energy efficient and provides gentle breeze to ensure cooling and comfort with minimum noise and disturbance. On this occasion Dr. Sandeep Mann, Dr. Yogesh Kumar and Dr. Ranjeet Singh were also present.
