    摘要： A cooling system has both pumped refrigerant economization and direct expansion cooling. When outside air temperature is low enough that pumped refrigerant economization can provide enough cooling to satisfy cooling demand, only pumped refrigerant economization cooling is used to provide cooling. When outside air temperature is low enough that pumped refrigerant economization can provide some but not all of the cooling needed to satisfy cooling demand, the pumped refrigerant economization is operated at one hundred percent capacity and the direct expansion cooling is operated at a capacity to provide any supplemental cooling that is needed. If the outside air temperature is high enough that pumped refrigerant economization cannot provide any cooling, then only direct expansion cooling is used to provide cooling.

    摘要翻译： 一个冷却系统既节省了制冷剂，又节省了直接冷却。 当室外空气温度足够低时，泵送的制冷剂节约能够提供足够的冷却以满足冷却需求，仅使用泵送的制冷剂节约冷却来提供冷却。 当室外空气温度足够低时，泵送的制冷剂节约可以提供满足冷却需求所需的一些但不是全部的冷却，泵送的制冷剂节约率以百分之百的容量运行，并且直接膨胀冷却以能够提供任何 需要补充冷却。 如果外部空气温度足够高，泵送的制冷剂节约不能提供任何冷却，则仅使用直接膨胀冷却来提供冷却。

    摘要： A cooling system includes a cooling circuit having an evaporator, a condenser, a compressor, an expansion device, a liquid pump, and a receiver/surge tank coupled between the condenser and the liquid pump. The cooling system has a direct expansion mode and a pumped refrigerant economizer mode. When the cooling system switches from the direct expansion mode to the pumped refrigerant economizer mode, refrigerant is flushed from the refrigerant/surge tank so that the cooling circuit is overcharged when it begins operating in the pumped refrigerant economizer mode.

    摘要： A pumped refrigerant cooling system having multiple pumping units for providing working fluid to a load to enable cooling of a space via the load. The pumped refrigerant cooling system operates the pumping units at less than capacity. When a pumping unit is deactivated, the output of the remaining pumping units is increased to maintain fluid flow.
