Open type freezing system in which air in the refrigerated warehouse circulates directly while the air is compressed by a compressor and cooled by an expander before adiabatic expansion to lower the temperature for cooling the warehouse. Unification of compressor and expander and use of power generated at adiabatic expansion for power of compressor to attain high efficiency.
Manufacturer: Mayekawa Manufacturing Co., Ltd.
Highly efficient freezing machine using natural refrigerant, utilizing up-to-date technologies reducing energy consumption, thereby contributing to reduction of CO2 emissions from fuel.
Carbon dioxide is cooled and condensed by ammonia with cascade condensers and then supplied to load as secondary refrigerant by a liquid pump. The load is cooled using vaporization latent heat of supplied carbon dioxide. Realizes higher energy-saving performance and lower environmental load through utilizing natural refrigerant efficiently and safely.
