Patent ID: 7832214

Claim:
An air-conditioning device for cooling comprising: a pump sending a thermal medium; a thermoelectric conversion unit absorbing heat from the thermal medium so as to cool the thermal medium; a target setting unit manually setting a target cooling value for cooling the thermal medium; and a controlling unit controlling a flow amount of the thermal medium from the pump based on the target cooling value and controlling a heat-absorbing amount of the thermoelectric conversion unit based on the target cooling value, wherein the controlling unit increases the flow amount of the thermal medium from the pump gradually from a first flow amount to a second flow amount in accordance with the target cooling value and stops the thermoelectric conversion unit from absorbing heat, when the target cooling value is smaller than a predetermined value; the controlling unit increases the heat-absorbing amount of the thermoelectric conversion unit in accordance with the target cooling value and keeps the flow amount of the thermal medium from the pump at the second flow amount, when the target cooling value is equal to or larger than the predetermined value; and the second amount of the thermal medium from the pump is in a range between 60% and 100%, when a maximum amount of the thermal medium from the pump is defined as 100% and when a minimum amount of the thermal medium from the pump is defined as 0%.
