The working form of evaporator and condenser is different, condenser is to cool the medium to liquify, external heat release; Evaporator is the medium of heat absorption gasification, absorption of external heat, that is, the refrigerant is changed from gas to liquid, is a condensation heat release process, its internal pressure is generally high; The refrigerant of the evaporator is changed from liquid to gas, which is a process of evaporation and heat absorption, and the internal pressure is generally low;
2, the appearance of the difference: evaporator shell stage for water, pipe stage for refrigerant; The condenser is the opposite. There is little difference in appearance, but the material of evaporator tube box is generally better than that of condenser. If the head tube box is cast it is generally condenser. In summary, the condenser is one of the main heat exchange equipment in the refrigeration device. Its function is to cool and condense the superheated steam of the refrigerant discharged by the booster of the refrigerator into the refrigerant liquid, and release the heat in the cooling medium, the commonly used cooling medium is: water and air.
3. Evaporator is the equipment used for heat exchange between refrigerant and low temperature heat source in the refrigeration system, and also one of the main heat exchange equipment in the refrigeration device. In the evaporator, the refrigerant liquid vaporizes at low pressure and low temperature to absorb the heat of the cooled medium, and becomes the refrigerant dry saturated gas or superheated steam under low temperature and low pressure, so as to generate and output cold capacity in the refrigeration system. The evaporator is located between the throttle valve and the air return main pipe of the refrigerator or between the liquid supply and the air return pipe of the vapor-liquid separation equipment, and is installed in the cold room or place where cooling and freezing are required.
4. Evaporator, as a heat-absorbing component, uses the volatile characteristics of liquid low-temperature refrigerant under low pressure to transform into steam and absorb the heat of the cooled medium to achieve the purpose of refrigeration. From the structure, it can be divided into box type, tube type, plate type and other different types. As a heat releasing component, the condenser can convert the high temperature and high pressure gaseous refrigerant compressed by the compressor into the liquid state of low temperature and high pressure, so as to emit heat to the outside world. It absorbs and releases with the evaporator, so as to realize the conservation of heat. From the structure, it can be divided into shell and tube type, casing type, plate type, water spray type and other different types.
