摘要： A shell side condenser inlet diffuser (114) for a vapor compression refrigeration system is provided. The diffuser (114) includes an inlet (127) to receive a compressed refrigerant from a compressor of a refrigeration system. A chamber is in fluid communication with the inlet (127) to receive compressed refrigerant, the chamber having an upper side and a lower side and lateral sides bridging the upper and lower sides, the chamber having a plurality of openings (186,188) to discharge refrigerant inside the condenser (112). A protrusion (176) is disposed inside the chamber. The protrusion (176) and the chamber are configured and disposed to diffuse and direct a flow of refrigerant from the compressor to inside the condenser (112), the refrigerant leaving the chamber having a higher pressure level than the refrigerant entering the chamber.

摘要： A system and method are provided for variable speed operation of a screw compressor (108) to obtain increased capacity and efficiency. The screw compressor (108) is connected to an induction motor (106) driven by a variable speed drive (104), wherein the screw compressor (108) has a variable output capacity that is dependent on the output speed of the motor (106). To obtain increased capacity and efficiency, the screw compressor (108) is operated at a speed greater than the screw compressor's rated speed and does not include a slide valve. The maximum operating speed of the screw compressor (108), which speed is greater than the rated speed, is related to the maximum operating speed of the motor (106) when operated at a voltage and frequency provided by the variable speed drive (104) that is greater than the motor's rated voltage and frequency in a constant flux or constant volts/Hz mode.
摘要翻译：提供了一种用于螺杆压缩机（108）的可变速度操作以获得增加的容量和效率的系统和方法。螺杆式压缩机（108）连接到由变速驱动器（104）驱动的感应电动机（106），其中螺杆式压缩机（108）具有取决于电动机（106）的输出速度的可变输出容量，。为了获得更高的容量和效率，螺杆式压缩机（108）以大于螺杆压缩机的额定速度的速度运行，并且不包括滑阀。螺杆式压缩机（108）的最大运行速度（该速度大于额定转速）与在变速驱动器（104）提供的电压和频率下操作时电机（106）的最大运行速度有关，大于电机额定电压和频率的恒定通量或恒定电压/ Hz模式。

摘要： A chiller system 10 includes a refrigerant loop 90, the refrigerant loop 90 further including a compressor 60, an air-cooled condenser arrangement 70 and an evaporator arrangement 80 connected in a first closed refrigerant loop 90. A motor 40 is connected to the compressor 60 to drive the compressor 60, a drive 30 is connected to the motor 40 to power the motor 40 and a power/control panel 50 controls the refrigerant loop 90. The power/control panel 50 and the condenser arrangement 70 are connected in a second closed coolant loop 100. The second closed coolant loop 100 provides cooling to the enclosure 120 and/or components 115 within the enclosure 120 disposed on a chill plate 110. Condensation is substantially prevented from forming inside the enclosure 120, despite the enclosure 120 lacking a humidity control device.

摘要： An oil separator for use in separating oil from refrigerant gas in a chiller system is provided. Its operation is based on centrifugal separation principles and does not require the use any type of filter or media pack to remove oil from refrigerant gas. The oil separator includes a non-circular (e.g., elliptical) refrigerant outlet pipe that transitions the linear flow from the inlet connection to a swirling (e.g., circular) flow within the cylindrical housing. The non-circular shape of the entrance to the refrigerant outlet pipe provides for more turbulent gas flow and a greater extraction of oil as well as minimization of pressure losses.
摘要翻译：提供了一种用于将冷冻机中的制冷剂气体分离的油分离器。其操作基于离心分离原理，不需要使用任何类型的过滤器或介质包来从制冷剂气体中除去油。油分离器包括非直线（例如，椭圆形）制冷剂出口管，其将线性流从入口连接转变成圆柱形壳体内的旋转（例如圆形）流。制冷剂出口管入口的非圆形形状提供更多的湍流气流和更大的油的提取以及压力损失的最小化。

摘要： Air cooled chillers having a condenser section (300) sized to match chiller capacity and auxiliary cooling requirements satisfied by use of an independent cooling coil (314) dedicated to providing auxiliary cooling. The independent cooling coil (314) is located within the current condenser (300), but utilizes available space within the existing condenser, as well as a small portion of the airflow driven by the existing condenser fan (320). Thus, the auxiliary cooling capacity is provided with a single dedicated coil design, but which otherwise uses existing equipment and space.
