A saline solution condensation temperature is low, so it can be used in medium and low temperature cold water machine carrying cold quantity is usually selected, calcium chloride, magnesium chloride, sodium chloride aqueous solution. The concentration of the brine, the condensation point depends on the concentration of salt added, condensation point decreased, when the condensation point down to the lowest point, if the concentration of added, condensation point increased. Then, as the concentration of low temperature cold saline brine when airborne refrigerant in the end how to grasp? East Star Refrigeration today and everyone together to analysis this problem.
If the concentration of salt in brine density will increase, so the pump power consumption increased delivery of saline. If you cut the heat capacity of brine, brine flow will deliver certain amount of cooling required increased, adding the same pump power consumption. Therefore, should be selected according to the concentration of saline brine condensation point below the minimum temperature of refrigerant in the system can show the criterion.
The common method is to choose the concentration of brine condensation point than cold water machine the transpiration of low temperature 5 to 8 DEG C (if the selection of tank type evaporator is 5 to 6 DEG C, the shell and tube evaporator is 6 to 8 DEG C). In view of this, Sodium Chloride Solution only use refrigeration system in temperature is higher than -16 DEG C, calcium chloride solution cooling system use not less than -50 DEG C in the evaporation temperature.
Because of the density of the above characteristics of brine, so low temperature in the refrigeration industry in saline water machine has been widely used in different industry refrigeration technology. Brine screw chiller Shenzhen Dongxing refrigeration company can provide 0 DEG C to -6 deg. brine or ethylene glycol aqueous solution and 5 --60 degree centigrade chilled water brine chillers, can be used as the ice storage and cold air distribution and various other places a host of chilled water.
