発電設備の冷却装置
Document Type and Number:
Japanese Patent JP7380303
Kind Code:
B2
Abstract:
To provide a cooling device for power generation equipment which can use natural refrigerants that have no environmental impact without problem with equipment even when the power generation equipment continues to operate if the device is minor even in a case in which a pinhole occurs in a cooling distribution, and does not need to make major changes to the current equipment.SOLUTION: In circulating a refrigerant through cooling pipes 22, 32, and 42 arranged in lubricating oil to cool the lubricating oil that lubricates sliding points of power generation equipment and cooling the lubricating oil, a refrigerant circulation cycle 50 that circulates the refrigerant through the cooling pipes is set as a heat pump cycle using dry air. The refrigerant circulation cycle 50 includes an expander-integrated compressor 51 in which a compressor 51a and an expander 51b are coaxially connected, and connects at least the pipes of the compressor 51a, a heat radiating device 52 that dissipates the compressed refrigerant, the expander 51b, a pressure adjusting valve 53, the cooling pipes 22, 32, and 42, and a check valve 54 are connected in this order.SELECTED DRAWING: Figure 1
