<p>A refrigerating circuit (1) for a refrigerating device has successively connected thereto a compressor (10), a condenser (11), an electric expansion valve (13), an evaporator (17), and a suction proportional valve (21). A control means (30) operates so that in suppressing the refrigerating capacity, it throttles the suction proportional valve (21) to change the state of the refrigerant on the delivery side of the evaporator (17) into the state of wet saturated vapor and sets the degree of opening of the electronic expansion valve (13) to change the state of the refrigerant in the whole interior of the evaporator (17) into the state of wet saturated vapor.</p> |
