Concentration control of brine in low temperature cold water machine

        Salt water solution has a lower condensation temperature, so it can be used in the medium and low temperature cold water machine to carry cold, usually choose calcium chloride, magnesium chloride, sodium chloride solution. The condensation point of salt water depends on the concentration of salt water, concentration, condensation point drops, when the condensation point drops to the lowest point, if the concentration and then add, the condensation point but 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 resolve this problem.

        If the concentration of the brine increases, the density of the brine will increase, then the power consumption of the pump transporting brine increases. If the brine of the specific heat capacity is reduced, then the delivery of a certain amount of cooling water flow will be increased, the same amount of 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.

        At present, the common selection method is to select the concentration of brine so that condensation point than the low temperature cold water machine transpiration temperature of 5 ~ 8 degrees Celsius (if the selection of water tank evaporator 5 ~ 6 degrees Celsius, the use of shell and tube evaporator is 6 ~ 8 degrees Celsius). In view of this, Sodium Chloride Solution is only used in the hair temperature is higher than the -16 of the refrigeration system, calcium chloride solution can be used in the evaporation temperature of not less than -50.

        Because of the density of the above salt water, so in the refrigeration industry in low temperature salt water chiller has been widely used in different process of refrigeration industry. 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.
