摘要： A method and control system for operating a refrigeration unit to permit random loading and unloading sequences of multiple compressors and unloaders. The random loading and unloading sequences of the two circuits of compressors and unloaders is performed by a microprocessor. A random sequence is selected at start-up and the selected sequence loads the compressors to full load, where upon another random sequence is selected to unload the compressors.The compressors are also loaded in response to the water temperature leaving the chiller. The leaving water temperature is compensated for by a return water temperature which determines the temperature drop through the heat exchanger. The temperature drop is divided by the number of active stages to determine the drop/stage, which is an indication of how the leaving water temperature will change when a capacity stage is either added or subtracted.

摘要： An improved cooler with level sensor for measuring variation in the liquid refrigerant level of a refrigerant within the cooler, comprises a cooler shell for holding the refrigerant, heat exchanger tubes for carrying the liquid to be cooled, and a liquid refrigerant level sensor comprising a probe extending to a point above the heat exchanger tubes, one or more thermistors; and a heating element. When the probe is totally within the vapor refrigerant above the heat exchanger tubes, the heater raises the temperature of the thermistors above the saturation temperature of the refrigerant. As the liquid refrigerant level begins to rise, the liquid refrigerant comes in contact with the outside of the probe. Since the heat transfer coefficient of the liquid refrigerant is significantly higher than that of the vapor refrigerant, the probe in that area is quickly cooled to the saturation temperature. This, in turn, increases the resistance of the nearby thermistor, causing the overall resistance of the thermistor circuit to increase. By measuring the resistance of the thermistor circuit, a porporant indication of the liquid refrigerant level can be obtained, and used to control an electronic expansion valve to adjust the liquid refrigerant level accordingly.
摘要翻译：一种用于测量冷却器内的制冷剂的液体制冷剂水平变化的液位传感器的改进的冷却器包括用于保持制冷剂的冷却器壳体，用于承载待冷却液体的热交换器管和包括探针的液体制冷剂液位传感器延伸到热交换器管上方的一个点，一个或多个热敏电阻; 和加热元件。当探头完全在热交换器管上方的蒸汽制冷剂内时，加热器将热敏电阻的温度提高到制冷剂的饱和温度以上。当液体制冷剂水平开始上升时，液体制冷剂与探针的外部接触。由于液体制冷剂的传热系数显着高于蒸气制冷剂的传热系数，因此该区域中的探针迅速冷却至饱和温度。这又增加了附近的热敏电阻的电阻，导致热敏电阻电路的整体电阻增加。通过测量热敏电阻电路的电阻，可以获得液体制冷剂液位的累计指示，并用于控制电子膨胀阀以相应地调节液体制冷剂水平。

摘要： A method and control system are disclosed for operating a refrigeration system to protect an evaporator in a refrigeration system against freezeups of a heat transfer fluid cooled in the evaporator by operation of the refrigeration system. A first signal indicative of the temperature of the heat transfer fluid in the evaporator and a second signal indicative of the temperature of the heat transfer fluid leaving the evaporator are provided to a microcomputer system which processes the first and second signals to determine when the temperature of the heat transfer fluid in the evaporator falls below the temperature of the heat transfer fluid leaving the evaporator by a selected amount. The microcomputer system generates an alarm signal to shut down operation of the refrigeration system if the microcomputer system determines that the temperature of the heat transfer fluid in the evaporator is less than the temperature of the heat transfer fluid leaving the evaporator by the selected amount.
