Abstract
A cooling mechanism includes a controller that controls the degree of opening of a variable expansion valve and the rotational speed of a compressor to cause a COcoolant to follow a route that is defined by set pressure values and set temperatures in surrounding relation to a critical point specified by a critical temperature of 31.1° C. and a critical pressure of 7.38 Mpa, in order for a temperature value measured by a first temperature sensor or a second temperature sensor to reach a set temperature.
