| Abstract: | According to the problems of starting-up high pressure and slow velocity of temperature drop,a tester was established and a pressure protector on the four-stage out-cascade refrigeration cycle was designed.The effect of suction and exhausting pressure and temperature drop was also analyzed.The experimental results show that the pressure protector can optimize the suction and exhausting pressure and increase the velocity of temperature drop. |
