    • A superheat control utilizes a sensor at a location downstream of an evaporator after some heat is delivered to the refrigerant. In one embodiment, the compressor is a sealed compressor with at least a portion of the refrigerant being heated by an electric motor. The temperature is sensed after the refrigerant temperature has increased after passing over the electric motor. In another embodiment, the refrigerant temperature is measured after some minimal compression and minimal temperature rise has occurred within the compressor pumping elements. In either case, by measuring the temperature of the refrigerant after some additional heat has been added to the refrigerant, the refrigerant superheat leaving the evaporator can be controlled to a lower value. The improved superheat control enhances the system performance by increasing system efficiency, system capacity and improving oil return to the compressor.
    • 过热控制在将一些热量输送到制冷剂之后,在蒸发器下游的位置使用传感器。 在一个实施例中,压缩机是密封的压缩机,其中至少一部分制冷剂被电动机加热。 在通过电动机之后制冷剂温度升高后感测温度。 在另一个实施例中,在压缩机泵送元件中发生一些最小压缩和最小温升之后,测量制冷剂温度。 在这两种情况下,通过在向制冷剂添加一定量的热量之后测量制冷剂的温度,可以将离开蒸发器的制冷剂过热控制在较低的值。 改进的过热控制通过提高系统效率,系统容量和改善对压缩机的回油来提高系统性能。

    • A mobile network comprises remote base transceiver station (BTS) nodes (3, 4) linked with a central base station controller (BSC) node (9). The latter is in turn linked with a mobile switching centre (MSC, 10), a visitor location register (VLR, 11), and a home location register (HLR, 8). Mobile stations (2, MS-A, MS-B, and MS-C) are located in the cells of the BTSs (3, 4). The remote nodes (3, 4, 3(a), 4(a)) are connected to the central node BSC (9) over a remote backhaul satellite connection. Calls are routed locally while the central nodes continue to manage calls and services from central feature-rich and typically more reliable switches of a core network. This means that calls set up between subscribers on the same remote node get connected within the remote node but call supervision is still carried out by the central nodes. The features and services of the existing core network are preserved. For example, if the calling subscriber is a pre-paid GSM subscriber and their account runs out during the call a release signal will still be sent from the central node to the remote even though the voice traffic is being handled by the remote node.
    • 移动网络包括与中央基站控制器(BSC)节点(9)链接的远程基站收发台(BTS)节点(3,4)。 后者又与移动交换中心(MSC,10),访问者位置寄存器(VLR,11)和归属位置寄存器(HLR,8)链接。 移动台(2,MS-A,MS-B和MS-C)位于BTS(3,4)的小区中。 远程节点(3,4,3(a),4(a))通过远程回程卫星连接连接到中央节点BSC(9)。 呼叫本地路由,而中央节点继续管理来自核心网络的中心功能丰富且通常更可靠的交换机的呼叫和服务。 这意味着在同一个远程节点的用户之间建立的呼叫在远程节点内连接,但呼叫监控仍由中央节点进行。 现有核心网络的功能和服务得以保留。 例如,如果主叫用户是预付费GSM用户,并且在呼叫期间他们的账户用尽,即使语音流量正在被远程节点处理,释放信号仍将从中央节点发送到远端。
