Title:
吸収式冷凍機
Document Type and Number:
Japanese Patent JP6999628
Kind Code:
B2
Abstract:
An absorption chiller (2) with a controller (30) configured to cause the dilute solution in the regenerator (11) to be heated by the heating medium and to cause an obtained concentrated solution to be supplied to the absorber (14) so as to perform a heat exchange with the cooling water in the cooling water pipe (12a, 14a), and to cause a vapor refrigerant generated by the heating of the dilute solution to perform the heat exchange with the cooling water of the cooling water pipe (12a, 14a) in the condenser (12), when the temperature detected by the cooling water temperature detector (31) is equal to or lower than a predetermined temperature, in a wet lay-up state including a state in which the cooling water inlet shut-off valve (V2) and the cooling water outlet shut-off valve (V3) are closed and the cooling water pipe (12a, 14a) is filled with the cooling water; and a first pressure relief valve (V9) provided on the cooling water pipe (12a, 14a), wherein the controller (3) is further configured to control the pressure relief valve to relieve an internal pressure in the cooling water pipe (12a, 14a) generated from the heat exchange.
