Abstract
A supersonic cooling system operates by pumping liquid. Because the supersonic cooling system pumps liquid, the compression system does not require the use of a condenser. The compression system utilizes a compression wave. An evaporator of the compression system operates in the critical flow regime where the pressure in an evaporator tube will remain almost constant and then ‘jump’ or ‘shock up’ to the ambient pressure.

A method for pressure shock-induced cooling, the method comprising:
- increasing the pressure of a working fluid with the aid of a pump that maintains a circulatory fluid flow in a circulatory flow path;
- isenthalpically increasing a pressure of the working fluid through a compression shock wave after the working fluid exits an evaporator tube;
- and
- cooling the working fluid after the isenthalpic increase in the pressure of the working fluid, the cooled working fluid provided to the evaporator by the pump without passing through a heater.
A method for cooling and heating a fluid circulated through a fluid flow path, the method comprising:
- increasing the pressure of a working fluid with the aid of a pump that maintains a circulatory fluid flow in a circulatory flow path;
- isenthalpically decreasing a pressure of the fluid in an evaporator;
- increasing the enthalpy of the fluid at substantially constant pressure, the enthalpy of the fluid increased in the evaporator following the isenthalpic decrease in the pressure of the fluid;
- isenthalpically increasing the pressure of the fluid following the increase in the enthalpy of the fluid, wherein the isenthalpic increase in the pressure of the fluid is shock-induced after the fluid exits an evaporator tube;
- and
- decreasing the enthalpy of the fluid at substantially constant pressure after the isenthalpic increase in the pressure of the fluid, the fluid provided to the evaporator by the pump without passing through a heater.
