Device for generating micro hydro power for buildings and process energy efficiency

摘要

The invention performs the technique called "pumping" in buildings using a lower tank and an upper tank, which are connected by a single pipe. The upper tank can be filled from the lower tank by a pump and the lower reservoir is fillable the upper tank by passing the water through a turbine. Both the pump and the turbine forming a unified machine with a motor, usually asynchronous induction, which is operated in reverse mode as either a motor or a generator. The invention also comprises a process that exploits differential price peak electricity during peak times and also reduce the peaks of the demand curve of the building, thereby enabling to improve energy efficiency.
