Designing A Refrigeration and Heat-Removal System for Rapid Detector Based on Freezing Point

摘要

Based on a detection method of freezing point, the paper proposed a simple, reliable, portable, and low-cost refrigeration and heat-removal system. Semiconductor refrigeration was chosen through comparing operating principles and features of three refrigeration solutions. Forced air cooling was then selected through comparing three heat dissipating methods for hot ends of semiconductor chilling. After determining the refrigeration and heat-removal solution, semiconductor refrigeration and heat dissipating by air cooling for the hot ends were selected as erection schemes, with stirring apparatus and condensate water processing unit. Mechanical compression was chosen for fixation through comparing features of three installation methods. It is safe to say that this refrigeration and heat-removal system can be used to rapidly detect the categories and quantities of adulterated milk with accuracy.
