Computer room in the application of industrial refrigeration air-conditioning chiller, because of is and production and processing equipment, the use of its running time is longer, if the customer in the daily lack of chiller for professional maintenance and routine equipment maintenance, and few consumption takes a periodic replacement, even from installed in no matter through a power machine open to it, then water chiller failure problem of frequency is very high, so small make up teach you know something about water chiller troubleshooting repair methods, such as chiller if the condition of high pressure on the low voltage side, the possible reasons to analyze how to judgment? 1, if the chiller is running, boot need refrigeration cooling side of chilled water temperature is too high, may be more than 40 ℃ hot water, then water chiller refrigerant low voltage value is very high, as the water chiller refrigeration run continuously, chilled water temperature will slowly drop after water chiller refrigerant low pressure value will be gradually reduce; 2, if the amount of refrigerant filling water chiller to join many, will appear the refrigerant pressure value of the chiller and low pressure value will be on the high side; 【 Room air conditioning 】 3, if the water chiller capillary throttling device or expansion valve damage, refrigerant throttling depressurization failures, so water chiller refrigerant low voltage value is higher; 4, if the water chiller runtime startup, high and low voltage value, there is no obvious change, i. e. without the compression ratio, and the value of the high and low pressure of water chillers in the state of downtime, this will likely is compression artifacts damaged inside the compressor, refrigeration compressor cannot be compressed; The above points can be summed up the chiller may be of low pressure values on the high side.
