1Productivity
If external mechanical rotary kinetic energy or electric motor is used to drive fluid pump set, then heat exchange efficiency is improved, but installation cost and energy consumption increase
Solution Approach 1:
The thermal energy fluid system serves itself by using its own pressure to drive the fluid actuation device, which in turn drives the secondary fluid pump set. This self-service mechanism eliminates the need for external mechanical rotary kinetic energy or electric motors, reducing energy consumption while maintaining heat exchange efficiency.
Solution Approach 2:
The patent replaces the conventional mechanical/electrical drive system with a thermal pressure-driven system. The thermal energy fluid's pressure replaces the function of external motors, substituting mechanical energy input with thermal energy utilization, thereby reducing energy consumption and installation costs.
2Device complexity
If thermal energy fluid is pumped to open space without return operation, then heat exchange process is simplified, but thermal energy is unnecessarily dissipated
Solution Approach 1:
The system recovers thermal energy by implementing a return operation where the thermal energy fluid circulates back through the heat exchanger after releasing thermal energy to the secondary fluid. This recovery mechanism prevents thermal energy dissipation while maintaining process simplicity through continuous circulation.
Solution Approach 2:
The thermal energy fluid maintains continuous circulation through the system, continuously releasing thermal energy to the secondary fluid and returning to the heat exchanger. This continuous useful action ensures thermal energy is consistently utilized rather than dissipated, improving energy efficiency while keeping the process straightforward.

AI summary
A building heating/cooling system utilizes secondary fluid that at least partially circulates through a secondary fluid pump set and a heat exchanger. The secondary fluid is heated or cooled by thermal energy exchange with a thermal energy fluid in the heat exchanger. The thermal energy fluid in the heat exchanger also drives the secondary fluid pump set that circulates the secondary fluid.
