Evaporator heat exchanger is used in the refrigeration system for heat exchange between refrigerant and low temperature heat source equipment, is also one of the main heat exchange equipment in the refrigeration device, in the evaporator, the refrigerant liquid vaporized at low pressure and low temperature absorb the heat of the cooled medium, becoming the refrigerant dry saturated gas or superheated steam under low temperature and low pressure, thus generating and output cold in the refrigerati
Evaporator heat exchanger as a heat transfer equipment, the application range is very wide, mainly used in the following areas:
(1) Chemical industry: Evaporators are widely used in distillation, crystallization, extraction and other processes in the chemical industry.
(2) Food field: The application of evaporator in the food field is mainly to concentrate or dry some food by evaporation.
(3) Pharmaceutical field: Evaporators are widely used in the process of concentration, drying or solvent recovery in the pharmaceutical field.
(4) Seawater desalination field: Evaporators are also widely used in the field of seawater desalination to remove the salt in seawater by evaporation and make fresh water.
(5) Environmental protection: Evaporators are also used in the field of environmental protection, mainly through evaporation to remove harmful substances in wastewater.
