Evaporator selection problem of the construction of large and medium low temperature cold storage, should as far as possible with traditional tube evaporator. Cold storage use cold tube which can realize the temperature easy to control, and no effects on motor energy consumption at the same time.
Cold compressor shut down, exhaust pipe can cool storage of cryogenic liquid ammonia, library evaporation temperature fluctuations small and mild temperatures continue long time.
Because of cold discharge pipe evaporation area than evaporation air cooler tubes of evaporation area is much bigger, so increasing heat transfer area is one of the most effective way to strengthen heat transfer.
Although cold exhaust pipe and cooling fan than a one-time investment, but the operation cost is relatively reduced. At the same time using cold tube refrigeration system can be simplified, easy cold storage equipment system maintenance and management.
