- product introduction:Application:
It is mainly used in low temperature cold storage below 10000T and IQF below 1T/h cooling source
Features:
The high temperature side is NH3, and the three-stage throttling refrigeration system with double flash tanks is adopted, which is energy-saving and efficient;
The low temperature side is CO2, which ensures that there is no oil in the evaporator and there is no performance degradation;
It is applied to evaporative condenser system, and lower than water cooling condensation temperature and energy saving;
The NH3 compound two-stage semi-hermetic screw compressor with permanent magnet variable frequency motor is energy-saving and efficient;
Motor cooled by siphon refrigerant has a good cooling effect without scaling, which is more energy-saving and safe than spray cooling;
The plate-shell oil cooler is also cooled by siphon refrigerant liquid, with small volume
Vertical centrifugal oil separator with high molecular sieve structure is adopted, with oil separation efficiency of 3ppm;
The horizontal siphon tank with the functions of liquid reservoir and washing oil separation is adopted to make the ammonia liquid entering the plate-shell condensing evaporator free of lubricating oil, so as to ensure that the heat exchange efficiency of the plate-shell heat exchanger will not be attenuated by lubricating oil, and there is no need to lay complex oil return pipeline, which is energy-saving and efficient;
Full liquid plate and shell condenser evaporator reduces the equipment height and can be transported as a whole;
The CO2 pump is one for use and one for standby to ensure the safe operation of the system;
The amount of ammonia in the system is small;
?Complete safety protection with fully automatic operation.
