BRINE REFRIGERATION EQUIPMENT
KTE-6000BR
Equipment Introduction
-
Brine is an antifreeze that is a heat-carrying medium that is cooled by refrigerant through an evaporator and transmits a freezing effect to the object to be cooled.
-
With the refrigeration system using such a brine system, the degree of cooling of the object to be cooled according to the concentration of brine used as a secondary coolant can be identified in real time, and accordingly, freezing performance measurement experiments can be conducted.
-
This equipment is designed to standardize, miniaturize, and set up the complex, large-scale, and concealed ice shaft refrigeration devices and automatic control operation panels for easy access for experimental practitioners.
-
Students can improve your practical skills by integrating experiments required to configure ice shaft refrigeration devices, designing and configuring automatic control circuits required for practice and operation.
Equipment Characteristics
-

Condition
-
1) Evaporating temperature : -15℃
-
2) Condensing temperature : 30℃
-
3) Temperature at inlet of compressor: -15℃(Dry gas)
-
4) Temperature at inlet of expansion valve: -25℃(sub-cooling temp. 5℃)

Formula
-
1) Refrigeration ability (Qe) = ha ― he
-
2) Compressor work (W) = hb ― ha
-
3) Condensing load (Qc) = hb ― he = Qe + W
-
4) Coefficient of performance (COP) = Qe/W
-
5) Compression Ratio (Pr) = P2/P1
