Summarizes the high and low temperature refrigerator

　　Original source: original author summarizes the high and low temperature refrigerator: Lin Frequency Instrument
　　high and low temperature refrigeration unit is the administrative center of the refrigeration equipment, if it experienced mechanical energy is converted into power equipment, the ultra-high pressure vapor, is tightening high-temperature vapor pressure at the end, the ability to work to ensure that the refrigeration repeatedly carried out, is a manufacturer of high and low temperature refrigeration units for your description of the summary, please read the article:

　　I talk about this ring test enterprises with less than normal: axial refrigeration units, which rely on the effectiveness of cohesion, have been sucked into the vapor tightening, a large amount of air conditioning and refrigeration to achieve 30000KW, super-heavy areas for air conditioning ﹑ super heavy-duty storage and logistics refrigeration equipment, the daily task firm, limiting the role of longevity long, large refrigeration lethal, can carry out the Promise nursed back to health.
　　High and low temperature there is such a positive displacement chillers, it is a familiar analogy, the basic principle is the daily tasks of daily tasks by improved volume of the cavity, the regularity sucked into the vapor volume tightening, back and forth refrigeration tightening machine: back and forth on the topic of activities to improved cylinder volume of daily tasks, according to the structure is divided into: full-open, semi-open two kinds.
　　High and low temperature fully open: air-conditioning cooling capacity lower than 60KW, used for small and medium sized central air-conditioning and refrigeration equipment, generators and drive components themed events have been open at the same time, the less power but not easy to Peixiu;
　　high cold box half-open: cooling amount of 60 ~ 600KW, ethnic groups can be used in air-conditioning refrigeration apparatus ﹑ generated independently from the crankcase Tonghuazuoyong generator housing and closed time, the daily task of firmly long life limit refrigeration great lethality, can be used for a variety of loads, can Peixiu, but slightly higher noise. Into tight unipolar type (type general practice, butterfly valve type, uninstall type, connection type) and a bipolar type tightening.
