摘要： The invention is concerned with a cooling system for cooling telecommunication equipment at an unattended microwave relay station or the like located in desert or like regions where there is a large difference between the maximum daytime temperature and minimum nighttime temperature. The cooling system includes an outdoor heat exchanger disposed outside and above a shelter accommodating the telecommunication equipment, an indoor heat exchanger disposed in the shelter and a heat storage means disposed at an intermediate level between these heat exchangers. These heat exchangers and the heat storage means are connected with one another by conduit means charged with a condenseable refrigerant, such that the refrigerant is naturally circulated in said conduit means by gravity. When the outdoor temperature is low at night, most part of the cooling energy absorbed by the outdoor heat exchanger is stored in the heat storage means, while the remaining part is used for cooling the telecommunication equipment, whereas during the daytime when the outdoor temperature is high, the cooling energy is released from the heat storage means to effectively cool the telecommunication equipment. The cooling of telecommunication equipment can thus be performed without requiring any external electric power and frequent maintenance work.
摘要翻译：本发明涉及一种用于在位于沙漠中的无人值守的微波中继站等处的通信设备的冷却系统，其中最大白天温度和最小夜间温度之间存在较大差异。冷却系统包括设置在容纳电信设备的防护罩的外部和上方的室外热交换器，设置在防护罩中的室内热交换器和设置在这些热交换器之间的中间水平处的蓄热装置。这些热交换器和蓄热装置通过装有可冷凝制冷剂的管道装置彼此连接，使得制冷剂通过重力自然地在所述导管装置中循环。当夜间室外温度低时，室外热交换器吸收的大部分冷却能量被储存在蓄热装置中，而其余部分用于冷却电信设备，而在室外温度为高的冷却能量从储热装置释放出来，以有效地冷却电信设备。因此，可以在不需要任何外部电力并且频繁地进行维护工作的情况下执行电信设备的冷却。

摘要： A rotary type expander is provided with two rotary mechanism parts which differ from each other in displacement volume. The outflow side of the first rotary mechanism part of small displacement volume is fluidly connected to the inflow side of the second rotary mechanism part of large displacement volume. The processes by which the volume of a first low-pressure chamber in the first rotary mechanism part decreases and the volume of a second high-pressure chamber in the second rotary mechanism part increases are respectively in sync. Refrigerant at high pressure is first introduced into a first high-pressure chamber of the first rotary mechanism part. Thereafter, this high-pressure refrigerant passes through a communicating passage and then flows by way of the first low-pressure chamber into the second high-pressure chamber while expanding. The after-expansion refrigerant flows out to an outflow port from a second low-pressure chamber of the second rotary mechanism part.

摘要： In a compression/expansion unit (30) serving as a fluid machine, both a compression mechanism (50) and an expansion mechanism (60) are housed in a single casing (31). An oil supply passageway (90) is formed in a shaft (40) by which the compression mechanism (50) and the expansion mechanism (60) are coupled together. Refrigeration oil accumulated in the bottom of the casing (31) is drawn up into the oil supply passageway (90) and is supplied to the compression mechanism (50) and to the expansion mechanism (60). Surplus refrigeration oil, which is supplied to neither of the compression and expansion mechanisms (50) and (60), is discharged out of the terminating end of the oil supply passageway (90) which opens at the upper end of the shaft (40). Thereafter, the surplus refrigeration oil flows into an oil return pipe (102) from a lead-out hole (101) and is returned back towards a second space (39). This reduces the amount of heat input to the fluid flowing through the expansion mechanism from the surplus refrigeration oil which has not been utilized to lubricate the compression and expansion mechanisms.

摘要： Disclosed is a displacement type expansion machine. In the displacement type expansion machine, a communicating passage (72) for allowing fluid communication between an expansion-process intermediate position and an outflow position in an expansion chamber (62) is provided thereby to allow the fluid at the outflow side to return to the expansion chamber (62). Such arrangement prevents the pressure of the expansion chamber (62) from being lowered to an excessive extent in predetermined operating conditions, thereby avoiding the drop in power recovery efficiency.

摘要： A scroll fluid machine includes a stationary scroll having a spiral wrap formed on an end plate and a moving scroll having a spiral wrap formed on an end plate. A polymer actuator for adjusting the amount of space between the wrap and the end plate is disposed in a recess formed at a tip of the wrap. The polymer actuator changes its shape along a height of the wrap to adjust an amount of the space. The polymer actuator also functions as a seal between the end plate and the wrap. The recess is formed such that a wall of the recess including an inner circumference surface of the wrap has a thickness different from that of a wall of the recess including an outer circumference surface of the wrap.
