The evaporation capacity of industrial high temperature refrigeration units is an influence factor

Evaporator is one of the four components of refrigeration system of industrial high temperature refrigeration unit group, which is a part or equipment that provides liquid refrigerant boiling evaporation.
evaporation is a heat-absorbing process, the evaporator is the embodiment of the refrigeration capacity and function of the refrigeration system of the industrial high temperature refrigeration unit group.
, depending on which object is cooled is air or liquid, the evaporator is commonly known as an air cooler or liquid cooler.
factors that affect the evaporation capacity of evaporators in industrial high-temperature refrigeration units?The main index to measure the evaporator of industrial high temperature refrigeration unit is heat transmission coefficient and heat transmission surface.
in order to improve the efficiency of the evaporator, the heat transmission coefficient should be increased first.
to improve the heat transfer coefficient is to improve the flow of heat between the refrigerant and the wall of the heat transfer tube.
Because the surface heat transfer coefficient when the refrigerant boils is much greater than the heat transfer coefficient between the vapor and the pipe wall, the contact surface of the liquid in the evaporator with the pipe wall is larger, and the steam generated when boiling is quickly drained.
, it is difficult to increase the heat transmission coefficient.
the heat transfer coefficient, the size of the heat exchange surface determines the evaporation capacity of the evaporator of the industrial high temperature refrigeration unit.
the number of heat transmission tubes and the use of rib tubes (fin tubes) can effectively large heat transmission surface, which is a common measure to improve evaporation capacity.
Industrial high-temperature refrigeration unit how to refrigerate industrial chiller according to refrigeration mode, large categories can be divided into water-cooled chiller and industrial high-temperature refrigeration unit, in terms of price, water-cooled chiller than industrial high temperature chiller is much lower; Incorporated cooling tower, external water pump can be used, industrial high-temperature refrigeration unit is mobile, no space, no other auxiliary, connected to the power supply can be used, but industrial high-temperature refrigeration unit only by fan cooling, there are entreaties to the environment: such as ventilation, humidity, temperature, air acid and alkali values and so on.
