Livestock and dairy operations are often seen to be requiring huge air and water heating requirements. In modern poultry farms, animals are kept in enclosed buildings where temperatures as well as air quality need to be kept under check so as to ensure the best growth and health of the animals. The air which is trapped indoors needs to be removed at regular intervals so as to remove moisture, toxic gases, odours, and dust. When this air needs to be heated, it requires a large amount of energy which can be provided by solar heaters. These can be installed in the buildings to heat the incoming fresh air. These systems can also be used to increase natural ventilation levels during summers.
Large amount of energy is needed in Commercial dairy farms to heat water and to clean equipment along with warming and stimulating cows’ udders. The process of heating water and cooling milk can utilise 40% of the dairy farm energy.
