ABSTRACT:
A high temperature heat pump comprising a low temperature heat exchanger to produce vapor of a first fluid from heat transferred from a second fluid to a mixture of liquid and vapor of the first fluid; a compressor to increase the pressure and temperature of the produced vapor; a high temperature heat exchanger to heat the second fluid to useful, high temperatures from the condensation of the first fluid; and an expander to lower the pressure and temperature of the first fluid producing a mixture of vapor and liquid.
