Cold State Engine for Utilising Air Thermal Energy to Output Work, Refrigeration and Water

摘要

A cold state engine utilising air heat energy to output work, refrigeration and water, includes a first cycle and a second cycle. The first cycle comprises of vaporiser, expander, and working fluid pump. The second cycle includes a vaporiser, circulation pump, air heat exchanger. The two cycles are opera lively interconnected via at least a vaporiser, piping, valves, sensors and a generator. Using air or water as a high temperature heat source, an expander generates cryogenic liquid as a low temperature heat source, using natural gases (such as N2, He, Air, CO2 etc.) as a working fluid, based on methods of cryogenic working fluid thermodynamic—refrigeration cycle and frost-free two stage heat exchange cycle.

1. An apparatus for Utilising Air Thermal Energy to Output Work, Refrigeration and Water, comprising a first cycle and a second cycle, the first cycle comprising: the vaporiser; an expander and a pump arranged to pump a cryogenic working fluid in a circuit through the expander and the vaporiser, and the second cycle comprising: the vaporiser, an ambient heat exchanger, and a circulation pump arranged to pump a heat-transfer liquid in a circuit through the vaporiser and the ambient heat exchanger; wherein the vaporiser is arranged to act as a heat exchanger to transfer heat fern the heat-transfer liquid to the cryogenic working fluid, which then absorbs heat to vaporise.-into high pressure vapour, the adiabatic expansion, occurs in the expander to produce work and cryogenic liquid, and the ambient heat exchanger is arranged to act as a heat exchange unit to transfer heat to the heat-transfer liquid from an external heat source (such as water or the surrounding air), and to output refrigeration, capacity, condensate and dry air.
