Treatment of Frosting in Refrigeration System of High and Low Temperature Test Chamber

Frost fall and wet stroke arrangement of the bottom pressure cylinder in the high and low temperature test chamber are generally caused by poor operation of the volatilization system software or the bottom pressure high and low temperature test chamber, and their omens and solutions are the same as those of unipolar. Frost fall of high pressure cylinder is usually caused by high liquid level of positive intermediate cooling tower, and its omen is the same as that of monopole. What are the solutions? Let's master it together with the small editor!

1. First, turn down the suction valve of the refrigeration compressor in the high and low temperature test chamber and unload it to at least the number of cylinders for operation.

2. Then close the liquid supply valve of the intermediate cooling tower and adjust the suction valve of the high pressure cylinder.

3. After the high pressure cylinder recovers, enlarge the suction valve of the bottom pressure cylinder, resume operation, and supply liquid to the intermediate cooling tower.

4. If the frost on the high pressure cylinder is serious, the generator set shall be stopped.

5. Align the intermediate cooling tower to solve the problem of liquid discharge.

6. The solution of cooling circulating water is the same as that of single pole solution.

2、 Prevention of frost falling:

Frost on the refrigeration compressor of the high and low temperature test chamber usually has signs in advance, such as the gloss of the surface paint on the side of the breathing chamber will suddenly fade and cause condensation water to frost. The temperature of the suction and exhaust pipes of the refrigeration compressor drops suddenly, the human body gets cold, the running noise is thick, and the pump casing vibrates with unclear noise. After this situation is found, corresponding countermeasures should be taken to adjust the cooling load of the high and low temperature test box system software.
