Container for storing water, installed in e.g. building, for heat pump, has outer heat exchangers arranged outside of first zone of container, so that heat exchange is performed by heat exchanger filled with nonfreezing liquid

摘要

The container has outer container (2) enclosing an inner container (5). The inner container is divided into four zones (13). The solar energy having preset temperature is stored is acquired and stored in the container. The outer heat exchangers (4) made of plastic, are arranged outside the first zone of the container, so that heat exchange is performed by the heat exchanger filled with nonfreezing liquid.
