【発明の名称】5又は8kW冷凍装置及び該装置のための遠心圧縮機のアッセンブリ
Document Type and Number:
Japanese Patent JP3247992
Kind Code:
B2
Abstract:
The 8 kW refrigerating system comprises a condenser, evaporator and two-stage centrifugal compressor assembly with an electric motor provided with a cooling system. The condenser inlet is connected to the compressor assembly outlet, while the condenser outlet is connected via the first and second choke elements to the inlet of the evaporator and to the cooling system. The evaporator outlet communicates with the compressor assembly inlet, the cooling system outlet communicates with the inlet of the second stage of the assembly. The cooling system is provided with a cooling skirt whose cavity lies between the stator and housing. The system is provided with a separator vessel, a recuperative heat exchanger and a heat-regulating valve controlled by the coolant pressure and temperature at the cooling skirt inlet and fitted in series with the separator vessel in the line connecting the condenser inlet to the evaporator. The separator vessel is connected by the gas phase to the coolant feed duct. The heat exchanger is connected by the coolant to the line connecting the condenser outlet to the evaporator inlet via the separator vessel. The second choke element is a heat-controlled valve regulated by the pressure and temperature of the coolant in the coolant discharge line from the cooling skirt.
