The performance of a cold room unit cooler (evaporator) depends on several design and operating parameters that determine how efficiently heat is removed from the storage space.1. Airflow RateAirflow generated by the fans is critical for heat transfer.Higher airflow increases the heat exchange rate.

Why do unit air coolers frost? What are the methods of defrosting? As an important component of the cold storage refrigeration system, when the unit air cooler operates at temperatures below 0°C and below the dew point of the air, frost starts to form on the surface of the evaporator, and the frost
