The condenser is a heat equipment, the evaporator absorbs heat with heat input power of compressor transformation with the transfer of the cooling medium ( such as water or air ).

Condenser: vapor of the refrigerant from the generator is cooled down by the cooling water running in the heat transfer tubes of the condenser thus becoming condensate after condensation.

Therefore, it is very important to study heat transfer and evaporation performance of pilot plant of wiped thin-film evaporator with an inner condenser and extend its applications.
