Noise reduction scheme:

1. main noise sources such as compressor with vibration reduction spring and damping pad can reduce noise, reduce equipment damage factors due to vibration, and extend the service life of equipment. The frozen pipe is fixed by a clamp to effectively reduce vibration

The internal wall of 2. refrigeration unit combined with high quality absorbing cotton can effectively reduce the noise effect of refrigeration unit.

Add vibration absorber hose outside of connecting the 3. compressor and the pipe.

The flow of the refrigeration system is automatically switched under different working conditions, and the excess system is cut off for energy-saving operation

• Cooling control: multi-stage evaporator combination can obtain more uniform and efficient cooling exchange efficiency and refrigeration output; flow control is automatically adjusted by their matching electronic expansion valves;

The 2) control system automatically adjusts the optimal energy saving condition of refrigerant operation according to test conditions; condensate pressure regulating valve (cooling water flow regulating device), evaporative pressure regulating valve (prevent evaporator freezing), and compressor return cooling circuit. The controller digital displays the high, low pressure, exhaust temperature and operating current of the compressor of the refrigeration system

3) Refrigeration process: the protection measures for the compressor are fully considered in the design of the refrigeration system, such as the automatic compressor suction and exhaust pressure protection function, which keeps the compressor to maintain the operating temperature within the normal temperature range, to avoid the compressor too cold or overheating, so as to prolong the service life of the compressor. High-quality anaerobic copper pipe gas protection welding method is adopted, which avoids the damage of oxides on the inner wall of the copper pipe to the refrigeration system and the compressor. In the design of the refrigeration system, the vibration reduction measures of the unit operation, such as the compressor installing spring shock absorber, and adopting the way of increasing arc bending on the refrigeration pipeline to avoid pipeline deformation and leakage caused by operation vibration and temperature changes, thus improving the reliability of the whole refrigeration system.

Other energy saving measures: the following effective energy regulation measures are adopted, such as refrigeration volume regulation, gas-liquid bypass regulation, evaporation temperature regulation, etc. At any low temperature point, the operation power can be reduced to half, reducing the operation cost and failure rate of the cooling system to a relatively economic state.

5) compressor air return temperature regulation: automatically adjust the air return temperature of the compressor to keep the compressor temperature within the normal range and avoid over-cold and overheating of the compressor.

6) vibration reduction measures: 1. Compressor: spring vibration damping.2. Refrigeration system: special rubber pad overall secondary vibration damping; the refrigeration system pipeline adds R and elbow to avoid the variation of the copper pipe caused by vibration and temperature changes, thus causing the rupture of the refrigeration system pipeline.

7) noise reduction: refrigeration cabinet: wavy special acoustic sponge.
