Carbon dioxide as a refrigerant has the advantages of high density, low viscosity, small flow loss, and good heat transfer effects. At the same time, carbon dioxide has excellent environmental performance, low cost and easy acquisition, good stability, and is conducive to reducing the size of refrigeration equipment. However, the use of carbon dioxide as a refrigerant also has correspondingly high requirements. The relatively high critical pressure and low critical temperature of carbon dioxide have also brought many difficulties to its use as a refrigerant, and one of them is the difficulty in ensuring the accuracy of filling. CR744 series filling machine adopts CACL subcritical state process filling technology and is equipped with CA-6170 rear guide ejector rod filling gun with exquisite design. Filling accuracy.
