Protection device, compressor overload protection. Under the rated temperature chiller, overload protection will jump at a certain current value, the current compressor motor off, and then protect the compressor 2, overcurrent protection. When the unit is running more than the rated current of freezing water, automatic stop running 3, low pressure protection. When the process unit operation with high and low pressure alarms and the unit will automatically stop running 4, ultra-low temperature protection. When the process of ultra-low pressure compressor operation occurs, the unit automatically stops 5, traffic protection. There are maximum and minimum pump flow, when this value is greater than or less than the water chilled water machine, the unit shut down 6, phase sequence / phase loss protection. Prevent reverse power protection devices have been 7, frost protection. Appear temperature is too low, the water circulation system is not 8, exhaust temperature protection. Excessive compressor fluid supply situation arise. Hung Fung brand frozen water machine Note: water-cooled chiller needs and outdoor cooling towers, circulating pumps used in conjunction with an open chilled water machine, the user needs based on water-cooled chiller cooling requirements, and select the appropriate cooling towers, circulating water pump; keep it cool cooling towers and water clean is very important, cooling water will affect the cleanliness of the water-cooled chiller life. Recommend appropriate filtration facilities, and water added preservatives, corrosion inhibitors, such as isothiazoline ketones; open chilled water machine, Maoming City, chilled water machine, water-cooler-long refrigeration industry by the Dongguan City-long Refrigeration Mechanical and Electrical Equipment Engineering Limited.
