Background technology:
The function of the compressor is to compress the steam with lower pressure into steam with higher pressure, so as to reduce the volume of steam and increase the pressure. The compressor sucks the working medium steam with lower pressure from the evaporator, increases the pressure and sends it to the condenser. It condenses into a liquid with higher pressure in the condenser. After throttling by the throttle valve, it becomes a liquid with lower pressure, and then sends it to the evaporator. It absorbs heat in the evaporator and evaporates into a steam with lower pressure, and then sends it to the inlet of the compressor to complete the refrigeration cycle, Due to the high load of refrigeration cycle, large industrial refrigeration systems mostly adopt the refrigeration cycle with more than two stages of compression and intermediate cooling. Compressor is the heart of refrigeration cycle, and its optimal design is particularly important. Therefore, for the refrigeration cycle commonly used in industry, considering the limitations of refrigeration coefficient, compressor efficiency and structure, designing an optimal refrigeration cycle with optimal refrigeration coefficient, reasonable compressor structure and low power consumption is the development trend of industrial refrigeration system design. In practice, the general method of refrigeration standard of traditional national standard specification is adopted.
The inventor found that there are at least the following technical defects in the prior art:
In practice, the design method of the prior art has complex system design and high requirements for the compressor, and the refrigeration system and compressor are generally designed by different professional manufacturers. Generally, the design standard is calculated according to the maximum refrigeration coefficient, and the compressor design parameters determined according to the maximum refrigeration coefficient calculation principle meet the design requirements, but can not meet the economic requirements; If the non-standard design is adopted, the design and manufacturing cycle of the compressor is long and the efficiency is low, which will cause the mismatch between the compressor and the process system and can not meet the cooling load requirements of the refrigeration cycle.
In view of this, the present invention is proposed.
