Abstract: PROBLEM TO BE SOLVED: To provide a device for attachment of a thermoelectric module, which hardly damages the thermoelectric module and lessens the leakage of cold. SOLUTION: In the device for attachment 2 of the thermoelectric module, an inner box 26, a heat conductive member 20, etc., are arranged within an outer box 25, and a cooling member 17 and a heat radiating member 18 are attached to both ends. The inner box 26 and the heat conductive member 20 are both in a concentric positions to the outer box 25, and space 65 exists between the whole peripheral face of the heat conductive member 20 and the inner face of the inner box 26, thereby the cold from the heat conductive member 20 is not transmitted to the side of a heat-insulating wall 5. Since the thermoelectric module 5 is pressed properly to the heat conductive member 20 and the heat radiating member 18 by the elastic force of O-rings 21 and 22, the transfer efficiency of the heat is high. Thermal deformation is absorbed by the O-rings 21 and 22.

Abstract: PROBLEM TO BE SOLVED: To simplify manufacture of a circular thermoelectric module while facilitating formation of multistage structure by sandwiching a rectangular thermoelectric module bonded with a plurality of Peltier elements arranged squarely between discs. SOLUTION: A circular thermoelectric module 10 comprises a rectangular thermoelectric module 11 sandwiched between discs 12, 13. The thermoelectric module 11 employs a known Peltier element wherein P type semiconductors and N type semiconductors are arranged side by side. The thermoelectric modules 11 are connected in series through upper and lower alternating electrodes and secured vertically by means of a ceramic insulating board. A set of P type and N type thermoelectric semiconductors constitutes a minimum unit of Peltier element. Solder is used frequently for bonding each thermoelectric semiconductor and the electrode. A known adhesive is used for bonding the disc 12, 13 and the thermoelectric module 11.

Abstract: PROBLEM TO BE SOLVED: To improve energy saving and properties of preservation of freshness of foodstuff. SOLUTION: A variable capacity compressor 7 and a control means 14 which makes the compressor 7 operate in a low capacity and also makes a refrigerating chamber damper 6 open while a freezing chamber damper 13 is held in a closed state, when the temperature detected by a refrigerating chamber temperature detector 5 is an upper-limit set temperature or above when a temperature detected by a freezing chamber temperature detector 4 is a set temperature or below, are provided. By this constitution, the variable capacity compressor is operated in the low capacity so as to cool only a refrigerating chamber, when it happens that the temperature of the refrigerating chamber alone rises to the upper-limit set temperature or above although the temperature of a freezing chamber is the set temperature or below. In this way the temperature of the refrigerating chamber is always kept to be a prescribed one and the freshness of foodstuff in the refrigerating chamber is prevented from lowering due to a rise in the temperature thereof.
