METHOD AND A DEVICE FOR STORAGE AND RECOVERY OF LOW TEMPERATURE THERMAL ENERGY

摘要

A novel method and device is provided herein for improved storage and recovery of low temperature thermal energy from a mass capable of storing such energy by heat exchange with a heat carrying medium, e.g. in combination with a heat pump. The conduit system for the heat carrying medium is arranged at the underside of a continuous bed which is placed on or in said mass, the latter being e.g. a body of water, watery or solid ground. The bed is preferably a floating plate construction of heat insulating material. Preferably at least part of the upper side of the bed is arranged to absorb solar radiation, which energy is transferred to said mass by washing the bed surface with water from the mass or another source. Especially on water or watery ground the bed may provide a support for e.g. plantations, grounds for ball sports etc.
