摘要： PROBLEM TO BE SOLVED: To provide a method of detecting leakage of a refrigerant in a refrigerating device capable of securely monitoring leakage of the refrigerant all the time even in an open space such as an outdoor space.
SOLUTION: In the method of detecting leakage of the refrigerant in the refrigerating device 10, outside air temperature (T0), cold water inlet temperature (T1) of an evaporator 40, cold water outlet temperature (T2) of the evaporator 40, evaporator pressure (P1) of the evaporator 40, cooling water inlet temperature (T3) of a condenser 30 and cooling water outlet temperature (T4) of the condenser 30 are detected. During operation, when a state where a temperature difference (ΔT1=T2-TR) between the cold water outlet temperature (T2) and evaporation temperature (TR) calculated from the evaporator pressure (P1) is larger than an operation predetermined value (A) is continued for a first predetermined time (Z1) or longer, leakage of the refrigerant is determined.

摘要： PROBLEM TO BE SOLVED: To provide a highly efficient motor cooler for a turbo refrigeration system.
SOLUTION: In this turbo refrigerator, taking the rotational speed of the motor as a rotational speed for a turbo compressor, as it is, is provided with a gas-liquid separator, which extracts refrigerant in the turbo refrigerator and separates the refrigerant into a gas phase and a liquid phase. A hole is formed in a stator, to form a passage for supplying refrigerant into a clearance between the stator and a rotor. Through the passage, the refrigerant of the gas phase extracted by the gas-liquid separator is introduced into the clearance for cooling. Because the refrigerant of the gas phase has less friction than that of the liquid phase (or the mixed two phases of the gas phase and liquid phase), the efficiency with which the motor converts electric power into mechanical power. is enhanced.

摘要： PROBLEM TO BE SOLVED: To provide a turbo refrigerating machine capable of coping with various temperatures.
SOLUTION: A turbo refrigerating machine of two systems is prepared, and the water heated by exchanging the heat with a refrigerant of a condenser of the first system is sent to an evaporator of a second system. The refrigerant is heated by exchanging the heat with the received water inside of the evaporator of the second system. Thus, the water of low temperature is supplied by the first system, the water of high temperature is supplied by the second system, and the temperature difference therebetween can be easily enlarged. Further by taking out the water flowing between the condenser of the first system and the evaporator of the second system, the water of intermediate temperature is supplied. Further by switching a valve, the first system and the second system can be functioned as independent two turbo refrigerating machines, large amounts of cold water and hot water can be supplied, and a large amount of ice can be made.

摘要： A condenser for condensing and liquifying a refrigerant by inducing the refrigerant into a receptacle (14), in which cooling water is fed through a plurality of thermal transmission pipes (15) which are arranged in bundles. A plate body (20) is provided between the bundles of the thermal transmission pipes, and slopes diagonally downwardly when viewed in cross-section from the direction of the length of the thermal transmission pipes. Consequently, the refrigerant falling toward the thermal transmission pipes at low positions is led diagonally downwardly by the plate body, so that the liquid film of refrigerant which adheres to the surfaces of the thertmal transmission pipes does not become too thick, thereby preventing reduction in the thermal transmittancy of the thermal transmission pipes.
