摘要： Operation of a transcritical refrigerant vapor compression system is controlled, when operating in a high capacity mode, through control of the refrigerant pressure in the refrigerant heat rejection heat exchanger (40) or the compressor (30) discharge pressure, also referred to herein as the high side pressure, so as to optimize energy efficiency. When operating in unloaded low capacity mode, such as for chilling perishable product during temperature maintenance operation, the high side pressure is controlled so that the system can operate in a continuous running mode.

摘要： A system includes a dynamic compressor and a controller having a processor and a memory. The compressor includes a first compressor stage having a first variable inlet guide vane (VIGV) and a second compressor stage having a second VIGV. The memory stores instructions that program the processor to operate the compressor at a current speed, a first position of the first VIGV, and a second position of the second VIGV to compress the working fluid, and to determine if a condition is satisfied. If the condition is not satisfied, the processor is programmed to continue to operate the compressor at the current speed, the first position of the first VIGV, and the second position of the second VIGV. If the condition is satisfied, the processor is programmed to change the second position of the second VIGV to a third position and maintain the first position of the first VIGV.

摘要： An air conditioner and a method of controlling the air conditioner includes a variable capacity compressor being operated at a maximum capacity in a case of starting an operation of the compressor after an extended stoppage for a lengthy period of time longer than a preset reference time, thus increasing a flow rate of a circulated refrigerant during an initial stage of the operation and increasing a quantity of heat generated from the motor of the compressor to vaporize and forcibly discharge a remaining liquid refrigerant from the compressor during the initial stage. Therefore, the variable capacity compressor of the air conditioner does not require heaters conventionally used for heating the refrigerant during such a stoppage, and so easy designing and production of the compressor is achieved, in addition to a reduction in a production cost of the air conditioner. This air conditioner also accomplishes a reduction in a maintenance cost thereof.
摘要翻译：一种空气调节器和空调的控制方法包括：在长时间长于预先设定的基准时间的长时间停止后开始压缩机运转的情况下以最大容量运转的可变容量的压缩机，在初始阶段增加循环制冷剂的流量，并且增加从压缩机的马达产生的热量，以在初始阶段汽化并强制地从压缩机排出剩余的液体制冷剂。因此，空调机的可变容量压缩机不需要通常用于加热制冷剂的加热器，因此除了降低空调的制造成本之外，还可以容易地设计和生产压缩机。该空调还实现了其维护成本的降低。

摘要： PROBLEM TO BE SOLVED: To provide a refrigerating device comprising an expander for recovering power, capable of properly setting its operating state according to various operating conditions while keeping high efficiency.
SOLUTION: In a heat source unit 15 for heating a heat medium water in a heat storage tank 16, a low stage-side compressor 52, a high stage-side compressor 62 and an expander 65 for recovering cover are disposed in a refrigerant circuit 30. The low stage-side compressor 52 is rotated and driven by a motor 54 connected with its driving shaft 53. The high stage-side compressor 62 is rotated and driven by a motor 64 connected with its driving shaft 63, and the expander 65. A high stage-side control portion of a controller 90 adjusts a rotating speed of the high stage-side compressor 62 so that a measurement value of an outlet water temperature sensor 77 reaches a target temperature. Further a low stage-side control portion of the controller 90 adjusts a rotating speed of the low stage-side compressor 52 so that a measurement value of a discharge pressure sensor 74 reaches a target high pressure.
