Apparatus for energy conversion

An embedded heat exchanger comprising:

• a ring module configured to be removably encased within a vane motor, wherein the vane motor is configured to receive a working medium fluid at an introductory pressure;
• and
• a peripheral enclosure along a periphery of the ring module, the peripheral enclosure defining:
• a closed space, wherein the peripheral enclosure is configured to receive an energy carrier fluid in the closed space;
• and
• an inner wall creating an interface between a working medium fluid within the vane motor and the energy carrier fluid within the closed space, for heat exchange to occur between the working medium fluid and the energy carrier fluid, wherein upon heat exchange between the working medium fluid and the energy carrier fluid, temperature and pressure of the working medium fluid are to increase whilst the temperature of the energy carrier fluid is to decrease,
• wherein the vane motor is rotated under combined effect of the working medium fluid entering the vane motor at the introductory pressure and the pressure of the working medium fluid increasing upon the heat exchange, and
• wherein the embedded heat exchanger is embedded within a wall of the ring module.

A method of energy conversion, the method comprising:

• releasing a working medium fluid stored in a storage container via a pressure release valve coupled with the storage container, wherein the working medium fluid is stored in the storage container at a first temperature and a first pressure, wherein, as a result of release, the temperature of the working medium fluid drops to a second temperature and the working medium fluid is released at a second pressure, the second pressure being less than the first pressure, and the second temperature being less than the first temperature;
• inputting the working medium fluid to a vane motor at a third pressure, the third pressure being greater than the second pressure;
• interfacing the working medium fluid within the vane motor with an energy carrier fluid, via an embedded heat exchanger embedded within a ring module encased within the vane motor, for heat exchange to occur between the working medium fluid and the energy carrier fluid, wherein upon the heat exchange, the temperature and pressure of the working medium fluid increases and the temperature of the energy carrier fluid decreases,
• wherein the vane motor is rotated under combined effect of the working medium fluid entering the vane motor at the third pressure and the pressure of the working medium fluid increasing upon the heat exchange, to drive an electricity generator mechanically coupled within the vane motor to generate electric power;
• and
• receiving the energy carrier fluid in a chiller heat exchanger from the embedded heat exchanger, wherein the chiller heat exchanger is configured to raise the temperature of the energy carrier fluid up from the third temperature.
