Wind Powered Heat Pump in a Dairy Farm Application. Final Report

摘要

A 30-foot high and 20-foot diameter Darrieus wind turbine was installed on a 120-cow dairy farm. The wind turbine generated 3-phase electrical power which was used, in parallel with utility power, to operate the refrigeration equipment for milk cooling at the dairy farm. A milk precooler and heat recovery from the refrigeration condenser were also installed to supply the warm water requirements of the dairy. The system was operated for 183 days and its performance, along with wind measurements for the same period, was analyzed to yield predictions for the size of wind turbine required to supply needed energy and the size of ice storage unit needed to store refrigeration capacity over periods of low wind.
