ABSTRACT = {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 design. These include a low pressure protection, a high pressure protection, an exhaust temperature protection and a differential pressure protection. Some 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 temperature. The 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 speed. Moreover, the Energy efficiency ratio (COP) decreases with the rise of
the saturation exhaust temperature. This 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.},
