Rain Water as a Factor of Enhancement of Power Efficiency of Heat Pumps
Summary
A scheme of the use of a heat pump with an underground collector damped with rainfall with the help of a special system is developed. The enhancement of power efficiency and a coefficient of weekly output of heat pumps due to purposeful flushing of underground collectors without additional auxiliary power is proved. When using the flat collector with a flushing system the expenditures for operation and maintenance of a heat pump of water-brine type go down from 735 to 688 Euro per year. Capacity of heat extraction is increased with the help of wetting of squashy ground from 10 to 30 Wt/m2 aproximately.
