What should I do if there is insufficient refrigerant in the chiller

What should I do if there is insufficient refrigerant in the chiller? Today, the editor of okmarts.com will teach you the correct way to deal with it. Please remember it!

1. When the water temperature is above 5℃ and the low pressure meter shows less than 3Kg/cm2, it means that the refrigerant is insufficient. Generally, we must first repair or treat the leakage of refrigerant, then replace the desiccant, re-vacuum and charge Fill with appropriate refrigerant.

　　2. When you find that the leaking refrigerant part is immersed in water, please stop the operation of the chiller, quickly drain the water in the water tank, and notify the company to send personnel to deal with and repair as soon as possible, so as to prevent the compressor from sucking water into the system and approve more serious damage.

　　 In addition, what should I do if I find that the refrigerant is insufficient?

　　(1) Failure phenomenon;

The refrigeration effect of the whole vehicle is poor, the air at the outlet is only slightly cool, and the manifold pressure gauge is used to check that the high pressure and low pressure side pressure are both low (when the compressor speed is 2000/mim and the ambient temperature is about 35C, the low pressure meter index is lower than 1kg/CM square, the high pressure meter index is lower than 10kg/CM square", while the flow of bubbles can be seen in the sight glass.

　　(2) Reason for failure:

　　 The refrigeration system has refrigerant leakage points, which results in insufficient refrigerant.

　　(3) Treatment method:

　　1) Use an electronic leak detector to find out the leakage point and perform treatment or replacement of parts.

　　 2) If the parts are not replaced, only a proper amount of refrigerant can be added; if the parts are replaced, a proper amount of refrigerating oil should be added as required, and sufficient refrigerant should be added after the system is vacuumed.
