Abstract
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.

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.
A method of using an apparatus to convert ambient air or water heat energy to output mechanical work, refrigeration and/or water in a two cycles, the method comprising a first cycle and a second cycle;
- wherein, in the first cycle, a cryogenic working fluid is heated in a vaporiser to a high pressure vapour state, and is then transferred, to an expander where it is permitted to adiabatically expand, and used to output work and/or cryogenic liquid thereby, causing a decrease in the temperature of the vapour until it is liquefied, the resultant cryogenic liquid then being pumped back to the vaporiser;
- and wherein, in the second cycle, a heat-transfer liquid is pumped from the vaporiser to an ambient heat exchanger where it receives heat from the ambient air, causing the temperature of the air to decrease and the temperature of the heat-transfer liquid to increase;
- the heat-transfer liquid being then circulated to the vaporiser to transfer heat to the cryogenic working fluid and vaporise, thereby causing the temperature of the heat-transfer liquid to decrease.
