Document Type and Number:
Japanese Patent JP2015190746
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a stable ground heat utilization heat pump device that easily switches a plurality of heat exchange parts according to temperature under the ground.SOLUTION: A ground heat utilization heat pump device includes a plurality of heat exchangers 101-104 buried in the ground, a compression unit 2, an expansion unit 3, a plurality of pipelines conducting a heat medium to the inside thereof, a first control unit 4, and a second control unit 5. The first control unit 4 changes over the direction of the heat medium in a corresponding pipeline, and the second control unit 5 changes over the direction of the heat medium and selects between use in heat collection or heat radiation operation with the heat exchangers 101-104 and non-use.
