Document Type and Number:
Japanese Patent JP7325111
Kind Code:
B2
Abstract:
To sufficiently exert a performance of a heat utilization apparatus.SOLUTION: A geothermal unit includes: a heat source-side piping system 10 forming a circulation flow channel of a heat medium liquid between an underground side and a ground side; a utilization-side piping system 30 forming a circulation flow channel of a liquid for utilizing heat at the ground side independently from the heat source-side piping system 10; a first heat exchanger 20 exchanging heat between the heat medium liquid flowing in the heat source-side piping system 10 and the liquid flowing in the utilization-side piping system 30; an auxiliary piping system 40 branched from the utilization-side piping system 30 at a downstream side with respect to the first heat exchanger 20, and joined to the utilization-side piping system 30 at a downstream side with respect to a branch point; a second heat exchanger 50 exchanging heat between the liquid flowing in the auxiliary piping system 40 and the air outside of the auxiliary piping system 40 in a passage of the auxiliary piping system 40; and a cylindrical duct 70 disposed in the second heat exchanger 50 for circulating the air.SELECTED DRAWING: Figure 1
