Abstract
A cold state engine utilizing air heat energy to output work, refrigeration and water, includes a first cycle and a second cycle. The first cycle comprises of vaporizer, expander, and working fluid pump. The second cycle includes a vaporizer, circulation pump, air heat exchanger. The two cycles are opera lively interconnected via at least a vaporizer, 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 utilizing air thermal to output work, refrigeration and water, comprising:
- a first stage cycle device and a second stage cycle device,
- the first stage cycle device comprising:
- a vaporizer;
- an expander and a pump arranged to pump a cryogenic working fluid in a circuit through the expander and the vaporizer, and
- the second stage cycle device comprising:
- the vaporizer, an ambient heat exchanger, and a circulation pump arranged to pump a heat-transfer liquid in a circuit through the vaporizer and the ambient heat exchanger;
- wherein the vaporizer is arranged to act as a heat exchanger to transfer heat from the heat-transfer liquid to the cryogenic working fluid, which then absorbs heat to vaporizer into high pressure vapor, 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;
- and
- wherein the expander is installed between the vaporizer and the working fluid pump to convert high pressure vapor into mechanical work and cryogenic liquid, the expander comprises a cylindrical case, piston wheel, band-shaped sealing ring, shaft, beatings base, ends and the cylindrical case has an inlet and an outlet for working fluid and series of connection pipes, the piston wheel has at least one circle of beehive shaped chambers as piston chambers, and the circle of piston chambers are connected in series to obtain sufficient working displacement.
A method of using an apparatus to convert ambient air or water heat energy to output mechanical work, refrigeration and water in 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 vaporizer to a high pressure vapor state, transferred to an expander where the high pressure vapor is permitted to adiabatically expand, and used to output work and cryogenic liquid, thereby causing a decrease in a temperature and a pressure of the high pressure vapor until it is liquefied, the resultant cryogenic liquid then being pumped back to the vaporizer;
- and
- wherein, in the second cycle, a heat-transfer liquid is pumped from the vaporizer to an ambient heat exchanger where the heat transfer liquid 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 vaporizer to transfer heat to the cryogenic working fluid causing the temperature of cryogenic working fluid to increase and vaporize, thereby causing the temperature of the heat-transfer liquid to decrease;
- and
- converting high pressure vapor into mechanical work and cryogenic liquid via the expander, wherein the expander is installed between the vaporizer and the working fluid pump and comprises a cylindrical case, piston wheel, band-shaped sealing ring, shaft, beatings base, ends and the cylindrical case has an inlet and an outlet for working fluid and series of connection pipes, the piston wheel has at least one circle of beehive shaped chambers as piston chambers, and the circle of piston chambers are connected in series to obtain sufficient working displacement.
