Frequently Asked Questions about Industrial Freezers
Author: Beijing Hengxing and Technology Co., Ltd. Source: http: //
Industrial refrigerators are being widely used by more and more companies and units. Industrial refrigeration equipment has become an important player in some industries. It is with industrial refrigeration equipment that we have known industrial freezers that make our lives change differently.
Among the applications of industrial refrigerators, the first thing that matters to us is the frozen series and the food field. In these two aspects, it has been shown how industrial freezers are close to our lives. Industrial freezers have once again highlighted its industrial characteristics during the summer. Make the frozen series more perfect.
Since it is a machine, there will be problems. Together with the climate change this season, we at Beijing Hengxinghe Technology Co., Ltd. made the following questions for the related problems of industrial refrigerators.
1. Compressor problems in industrial refrigerators What is the cause of frosting in the lower part of the compressor (low pressure) of industrial refrigerators? This is a Japanese compressor, 5p compressor, 5p chiller under normal working conditions, the cooling effect can also be achieved, that is, the compressor body frost. The frosting area is over 90%. How should it be solved?
Hengxing and: The low pressure tube of the compressor is frosted, but the body should not be frosted. If the body is frosted, it will cause liquid impact, which will cause damage to the internal parts of the compressor, such as connecting rods, pistons and valve plates. There are several reasons for the above reasons. The first point is that there are too many refrigerants. The second point is if there are multiple units (the combined unit has a control panel to set the start and stop time of each unit), then the frosting unit is turned on. Long, the third point is a unit, one is that the expansion valve is too large, (can be fine-tuned to small points), if the electronic expansion valve needs to adjust the circuit control panel. Whether it is open type, or semi-closed, fully enclosed, 5p or a few p and other compressors, it is found that the body frosting phenomenon is basically caused by the above reasons. It can also be referred to too much refrigerant or excessive expansion of the expansion valve.
2. The problem of low pressure and oil pressure difference in industrial refrigerators Why is the high pressure of industrial refrigerators under normal conditions such as low pressure and oil pressure difference? When the freezer works, the low pressure is normal (0.45MPa), the cylinder temperature is normal (70-80 degrees), but the high pressure is only 1.0MPa, the host current is only 75A, the chilled water temperature can not drop, the refrigeration effect is not good. How can I solve it?
Hengxinghe: The compressor efficiency is reduced or the valve plate and valve disc are leaking. (recommended for repair)
3, the temperature control problem of industrial refrigerators How to control the temperature of industrial refrigerators? Is controlling the cooling power or controlling the flow of water?
Hengxinghe: It is difficult to understand your problem. Each machine has a rated cooling power. When the freezer meets the required outlet temperature, the compressor will automatically stop working. The pump will cycle normally and the water will be cooler than you. At the set temperature, the compressor will automatically restart and work, and the temperature requirements can be set on the operation panel.
Through the above questions and answers, I hope to help everyone. We will continue to summarize the problems that often arise in the industrial refrigeration industry. I hope that these knowledge summaries will be helpful to the majority of users.
