sealed screw water chiller air conditioner

AUX air-cooled screw compressor heat pump / chiller with the world's leading semi-enclosed twin-screw compressors, superior performance and reliable operation, long service life, including: 1. use of dual-axis rotating exhaust design (gear ratio 5: 6), increased compression ratio and efficiency, refrigerant cooled motor, improve motor efficiency, energy saving up to 10%; 2. compression automatically Vi (content volume ratio) control, to avoid excessive compression and cooling loss due to realized in the wide range of applications to high efficiency; 3.asymmetric surface profile closely with twin-screw type, reducing the bearing and retaining shelves design stress, ensure the compressor is running smoothly, reducing noise and vibration. Water side heat exchanger shell and tube heat exchange with internal thread, the refrigerant in the pipe, water pipe outside the flow, with a compact, light weight, small occupation area, return the oil to facilitate the heat transfer efficiency is high. Air-side row heat exchanger tubes from the four condensation, inverted M-type arrangement, efficient aluminum fins from the copper and mechanical expanding, heat pump units are hydrophilic aluminum fin.
