SUPER LOW TEMPERATURE CASCADE REFRIGERATION SYSTEM USING ENVIRONMENTAL FRIENDLY NATURAL REFRIGERANTS

摘要

The present invention is to provide a dual refrigeration system that can implement ultra-low temperature by using an environmentally friendly natural refrigerant to use ammonia on the high pressure side and ethane refrigerant on the low pressure side is a refrigeration system that can implement an ultra-low temperature below -90 ℃ will be.;The refrigeration system of the present invention has an effect of ensuring a stable operation at all times by mounting a small auxiliary cooler to prevent this, especially when the discharge side of the low-pressure compressor is a high temperature and high pressure drops sharply.;Natural refrigerant, cryogenic, binary refrigeration system, ammonia, ethane, environmental pollution, ozone layer
