Hitachi screw chillers use the latest Hitachi twin screw compressor to improve the structure of the heat exchanger, comprehensively improving unit performance and efficiency.
Can provide a wide variety of application products:
Water cooled: low temperature dual working condition unit
(Minimum temperature can reach – 20 ℃)
Heat recovery models, water source heat pump units, etc
Air cooled: year-round operating models, hot water units
Ultra quiet unit (industry’s lowest noise
Product refrigeration capacity range: above 45kW
Compared with other types of compressors, Hitachi screw compressors generally have the following advantages, and are widely used in air conditioning, refrigeration, plant equipment, air heating, and other aspects.
① The screw compressor has few sliding parts, and there are no parts such as actuating valves that must be exchanged in a short period of time. Therefore, it has high reliability, and there is no need for long-term overhaul The structure is simple, and the number of main parts is about 1/10 of that of reciprocating type (compared to our company) Adopt double sealing structure, low noise.
④ The refrigerant compression is low vibration because it is compressed through continuous suction.
⑤ High efficiency, especially in low-temperature applications, air heat source cooling and heating, can play an outstanding performance. ⑥ There are two methods of capacity control: phased and continuous, which can widely adapt to different needs.
⑦ If liquid refrigerant is injected at the suction side of the compressor, the temperature of the discharged gas will not rise above 120 ℃. ⑧ Use a special synthetic lubricating oil that has a discharge temperature of 120 ° C and does not carbonize or deteriorate@ The starting load of the compressor is small. The motor can be started by using a small starting flow delta type（ λ—— △）。
