1 Purpose The purpose of this document is to provide a brief overview of refrigerants R410A and R407C, describe their characteristics and compare their environmental impact, regulatory compliance and resulting system efficiency.407C and R410A R407C is a non-ozone depleting blend of three HFC refrigerants (R32, R125, R134A) and was designed to match as closely as possible R22 pressure and performance to allow a smooth transition from R22 to R407C.
Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetative cover.
There are essentially four reasons why wind energy is a bad idea. Wind can only produce electricity when the wind is blowing at between 6 mph and 55 mph. Above 6 mph, it gradually increases its output until it reaches a maximum output at around 35 mph. Above 55 mph, the wind turbine is shut down to prevent damage to the turbine.
