摘要： In an absorption chiller/absorption chiller-heater wherein a pressure rise preventing means such as a safety valve (26), rupture disk or breakable plate is disposed in a high temperature regenerator or in the refrigerant vapor piping from the high temperature regenerator, with the discharge opening of the pressure rise preventing means being open to the atmosphere, in order to prevent the pressure rise in the high temperature regenerator (18), the discharge opening (28) of safety valve (26) is connected to low pressure units such as the low temperature regenerator (16) through pressure relief piping (30) so that, when the safety valve (26) is activated, the refrigerant vapor and absorption solution of the high pressure side will be discharged to low pressure units such as the low temperature regenerator (16) designed so as to generally maintain a vacuum therein during operation. By virtue of this construction, even when the pressure in the high temperature regenerator increases during operation causing the safety valve, rapture disk or the like to operate, it is possible to maintain the pressure reduction, assuring safety and avoiding the bad influence of corrosion due to open-to-atmosphere trouble, and also to quickly and readily perform the restoration.

摘要： The invention provides a screw compressor with increased efficiency at part load and a refrigerator capable of increasing the performance of an economizer circuit in a part load region. An inverter (22) controls the rotational speed of a motor (27) to control the capacity of a screw compressor (21). Since no slide valve is provided in the screw compressor (21), compression chambers (C1, C2) are sealed at part load, and the refrigerant is spouted through an economizer passage to the compression chambers (C1, C2). Consequently, refrigerant supply will not become short if it is spouted into the compression chambers (C1, C2). The efficiency at part load thus increases by the fact that the motor (27) and the screw rotor (33) rotate at low speed and that the refrigerant spouted through the economizer passage has a sufficient cooling effect without affecting the refrigerant supply to the compression chambers (C1, C2) at part load.

摘要： In a freezing cycle, if the pressure in a high-pressure line (8) reaches an abnormal level, the high-side pressure is released toward a low-pressure line (9) to lower the pressure without releasing the coolant into the atmosphere and the coolant is released into the atmosphere only when the pressure in the low-pressure line (9) reaches an abnormal level. A first means for a safety (10) that communicates between the high-pressure line (8) and the low-pressure line (9) is provided and a second means for safety (11) is provided between the low-pressure line (9) and the atmosphere, so that if the high-side pressure reaches a level equal to or higher than a first pressure level, the first means for safety (10) is engaged to leak the high-pressure coolant in the high-pressure line (8) into the low-pressure side to allow the increase in the pressure in the high-pressure line (8) to be absorbed in the low-pressure line (9), thereby lowering the pressure in the high-pressure line without releasing coolant to the outside. Since the coolant is released into the atmosphere by the second means for safety only if the pressure in the low-pressure line (9) reaches a level equal to or higher than a second pressure, the quantity of coolant released to the outside of the freezing cycle is minimized.
摘要翻译：在冷冻循环中，如果高压管线（8）中的压力达到异常水平，则高压侧压力朝向低压管线（9）释放以降低压力而不将冷却剂释放到大气中并且只有当低压管路（9）中的压力达到异常水平时，冷却剂才释放到大气中。提供在高压管线（8）和低压管线（9）之间连通的用于安全装置（10）的第一装置，并且在低压管线（9）和低压管线）和大气的压力，使得如果高压侧压力达到等于或高于第一压力水平的水平，则第一安全装置（10）接合以泄漏高压管路中的高压冷却剂（ 8）流入低压侧，以允许高压管线（8）中的压力增加在低压管线（9）中被吸收，由此降低高压管线中的压力而不释放冷却剂到外面去。由于只有当低压管路（9）中的压力达到等于或高于第二压力的水平时，冷却剂才通过第二安全装置释放到大气中，所以释放到冷冻外部的冷却剂的量周期最小化。
