摘要： Evaporative coolers are disclosed. An evaporative cooler includes a cooler housing, a centrifugal fan, and a motor. The cooler housing defines an interior region, a single air inlet, and an air outlet. The single air inlet is positioned to permit air flow into the interior region generally along an inlet axis. The air outlet is positioned to permit air flow from the interior region generally along an outlet axis. The inlet axis and outlet axis are angled with respect to one another. The centrifugal fan is mounted within the interior region of the cooler housing. The centrifugal fan is oriented to rotate about a vertical axis that is substantially orthogonal to the inlet and outlet axes. The motor is mounted within the interior region of the cooler housing and is coupled to the centrifugal fan. The motor is configured to rotate the centrifugal fan about the vertical axis.

摘要： A method for measuring characteristics of a power line signal having a fundamental frequency is provided. The method includes estimating the fundamental frequency of the power line signal, and generating a sampling clock that is substantially synchronized to the estimated fundamental power line frequency. The power line signal is sampled with the substantially synchronized sampling clock to generate data samples that include one or more substantially complete cycles of the power line signal. The data samples are processed to detect zero crossings of the power line signal, and the detected zero crossings are used to calculate an r.m.s. voltage of the power line signal measured over one full cycle, commencing at a zero crossing, and refreshed each half-cycle. Other aspects are also provided.
