PANEL-TYPE HEAT EXCHANGER FOR UNDERGROUND THERMAL SOURCE HEAT PUMP

摘要

PROBLEM TO BE SOLVED: To provide a ground burial heat exchanger which is used for an underground thermal source heat pump system and can provide immense advantages in terms of cost containment, shortening in work periods and the like compared with existing ones.SOLUTION: A panel-type heat exchanger 1 for an underground thermal source heat pump includes: a steel plate 2; a concrete layer 3 attached to a surface on one side of the steel plate 2; and a pipe 4 embedded in the concrete layer 3. The steel plate 2 has a plurality of plate-like ribs 5 on a surface on a side opposite to the surface attached with the concrete layer 3. The pipe 4 has: an inlet 6 through which a liquid medium passing through the pipe is taken from an outside of the panel-type heat exchanger 1; and an outlet 7 for discharging the liquid medium taken from the inlet 6 to the outside of the panel-type heat exchanger 1.
