Fully automatic water-cooled screw chiller

The fully automatic water-cooled screw chiller can be used in various industries such as plastic, electroplating, electronics, chemical, medical, purification, food, metallurgy, etc. to provide cooling system support and engineering. At the same time, it also provides high-performance water systems for shopping malls, office buildings, hotels, hospitals, residential villas and other places to create a quiet and comfortable living and working environment for customers.

　　Fully automatic water-cooled screw chillerA central air conditioning unit that uses water as the cooling medium in conjunction with a screw type chiller and a cooling tower or other stable cooling water source to meet the year-round cooling needs of buildings or process systems. The unit adopts a twin-screw compressor and a designed evaporator, which is energy-saving and efficient.

　　Fully automatic water-cooled screw chillerIntroduction:

The chiller produced by Shanghai Hanyi Refrigeration Machinery Co., Ltd. is an industrial chiller that uses a screw compressor to provide a large cooling capacity. Therefore, it is commonly used in industries such as injection molding, printing, concrete construction, chemical industry, pharmaceutical and food industry, central air conditioning system, etc.

High Efficiency and Energy Saving

1. The refrigeration energy efficiency ratio is 5.0, and the partial load reaches 5.5; 2. The host adopts a semi enclosed screw compressor, with an integrated motor and screw, and no shaft seal leakage; 3. The electrical and refrigeration system accessories are branded.

low-carbon operation

1. The unit can implement intelligent program control according to the demand of the load: 100%, 75%, 50%, 25%, saving energy consumption; 2. The total number of components in screw compressors is only 1/10 of that of reciprocating compressors, with a simple structure, few vulnerable parts, no suction or exhaust valves, insensitivity to wet stroke, and low failure rate; 3. The screw compressor can operate for up to 40000 hours.

Safety protection device

1. Pressure protection: high and low voltage electrical automatic protection devices; 2. Motor protection: undervoltage protection, phase loss protection, reverse phase protection, overload protection, motor overheating protection, oil shortage protection; 3. Anti freezing protection: When the temperature of the chilled water is too low, the unit will automatically shut down; 4. Safety valve protection: When the refrigerant pressure exceeds a certain value, the safety exhaust valve will automatically open.
