Heat engines move heat from a source to a sink. In a subset of heat engines, called heat pumps, the temperature of the source is below that of the sink. A subset of heat pumps, called working-fluid heat pumps, accomplishes the heat-pumping function by varying the temperature of a working fluid over a range that includes the temperatures of both the source and the sink. A subset of working fluid heat pumps, called Bernoulli heat pumps, accomplish this temperature variation of the working fluid by means of Bernoulli conversion of random molecular motion into directed motion (flow). This invention is a Bernoulli heat pump in which Bernoulli conversion is accomplished using a rotating disk, similar to those used in computers for data storage. Most working fluid heat pumps used for cooling and heating accomplish the temperature variation by compression of the working fluid. In contrast to compression, Bernoulli conversion consumes no energy.
