Temperature control and dehumidification pipeline system for refrigeration house

The temperature control and dehumidification pipeline system comprises a refrigerating unit, an air cooler, a dehumidification temperature control pipeline and a control system, the temperature control and dehumidification pipeline is arranged in a pipeline, leading to the air cooler, of the refrigerating unit and comprises a temperature control pipeline and a dehumidification pipeline, and the temperature control pipeline and the dehumidification pipeline are connected in parallel; the original system layout of the refrigeration house is changed, the constant pressure device is used for adjusting the pressure in the pipeline, the evaporation temperature in the pipeline is lower than the dew point temperature in the refrigeration house, when exhausted air passes through the air outlet of the air cooler, the temperature on the fins is lower than the dew point temperature of the air in the refrigeration house, water drops are separated out from the air on the fins, and dehumidification is achieved.
