摘      要：In order to ensure the safe operation of the compressors used in water chillers,in the present study some interlock protections have been added to the related *** include a low pressure protection,a high pressure protection,an exhaust temperature protection and a differential pressure *** tests have been conducted by tuning the saturation suction and exhaust temperatures of the compressor through adjustment of the cold source outlet temperature and the ambient *** results show that the ambient temperature increases with decreasing device load and increasing fan speed under the same saturated suction temperature;the device refrigerating capacity steps up with augmenting load and dropping saturation exhaust temperature,while it is not greatly affected by the fan ***,the Energy efficiency ratio(COP)decreases with the rise of the saturation exhaust *** parameter is not affected much by the device load and fan speed at high saturation exhaust temperature,while it improves on increasing the device load and decreasing the fan speed at low saturation exhaust temperature.
