Temperature adjustment device and temperature adjustment system

A temperature adjustment system for wine stored in a concrete wine tank, the temperature adjustment system comprising:

• a first temperature adjustment device;
• and
• a second temperature adjustment device,
• wherein each of the first temperature adjustment device and the second temperature adjustment device includes:
• a circulation pipe including an inlet port configured to be on a surface of the concrete wine tank, an outlet port configured to be on the surface of the concrete wine tank, and a main pipe portion configured to be embedded in a wall of the concrete wine tank;
• underground water inside the circulation pipe;
• an extraction pump configured to pump up the underground water, the extraction pump including a feeding pipe portion which is coupled to the inlet port of the circulation pipe;
• and
• a discharge pipe portion coupled to the outlet port,
• wherein:
• the first temperature adjustment device and the second temperature adjustment device are configured to circulate the underground water inside the main pipe portion;
• the first temperature adjustment device is configured to be at a first position in a vertical direction of the concrete wine tank;
• the second temperature adjustment device is configured to be at a second position in the vertical direction of the concrete wine tank;
• the first temperature adjustment device and the second temperature adjustment device are configured to control an upper-side temperature of the wine in the concrete wine tank and a lower-side temperature of the wine in the concrete wine tank to be different by 1° C. to 2° C.;
• and
• the circulation pipe of the first temperature adjustment device is discontinuous from the circulation pipe of the second temperature adjustment device such that the circulation pipe of the first temperature adjustment device is always in fluid noncommunication with the circulation pipe of the second temperature adjustment device.

• an extraction pump configured to pump up the underground water;
• and
• a temperature adjuster configured to adjust a temperature of the underground water and coupled to:
• (i) a feeding pipe portion of the extraction pump configured to receive the underground water;
• (ii) the inlet port of the circulation pipe;
• and (iii) the outlet port of the circulation pipe,
• wherein:
• the first temperature adjustment device and the second temperature adjustment device are configured to circulate the underground water inside the main pipe portion while the temperature of the underground water is adjusted;
• the first temperature adjustment device is configured to be at a first position in a vertical direction of the concrete wine tank;
• the second temperature adjustment device is configured to be at a second position in the vertical direction of the concrete wine tank;
