<p>This cooling cycle (10) is a vapor compression cooling cycle having a vaporizer (24) and a vaporizer (17). The vaporizer (24) cools cell-directed air which blows toward a secondary cell (26) as a result of the vaporization of a low-pressure coolant. The vaporizer (17) cools air-conditioning air which blows toward a space to be air conditioned as a result of the vaporization of a low-pressure coolant. A circulation-ventilation channel (34) is formed in the interior of a casing (32) and circulates the cell-directed air, in order, between the air-discharge side of the vaporizer (24), the secondary cell (26), and the air-intake side of the vaporizer (24). The present invention controls in a manner such that the coolant vaporization temperature in the vaporizer (24) is not higher than 0°C, while the coolant vaporization temperature in the vaporizer (17) is higher than 0°C.</p> |
