Description
Technical Field
The utility model relates to a novel not frozen liquid circulation refrigeration plant belongs to not frozen liquid circulation refrigeration plant technical field.
Background
The solubility of refrigerant and oil is divided into 2 cases of limited dissolution and complete dissolution, when the refrigerant and mineral oil are limited dissolution, the layering can occur when the content of lubricating oil in the refrigerant exceeds a critical value, the lower part is a lean oil layer, and the upper part is an oil-rich layer. The excessive content of the lubricating oil in the liquid refrigerant participating in the circulation can seriously affect the economical efficiency and the stability of the system operation, and even cause the system to be incapable of working normally. The reduction of lubrication oil in the compressor may have an effect on the lubrication safety of the compressor. In order to ensure the normal operation of the refrigeration system, measures must be taken to effectively control and stably maintain the content of the lubricating oil in the liquid refrigerant at the low-pressure side.
Disclosure of Invention
In view of the above, it is necessary to provide a circulation cooling system which can reduce the operation power of a pump, is easy to maintain, and has a good cooling effect.
The utility model provides a novel do not freeze liquid circulation refrigeration plant, includes compressor breathing pipe, evaporimeter, low pressure circulation bucket, cistern, refrigerant pump, oil return controlling means, compressor induction port, the low pressure circulation bucket passes through the pipeline and links to each other with the cistern, and the low pressure circulation bucket passes through the pipeline and links to each other with the compressor breathing pipe, and the low pressure circulation bucket passes through the pipeline and links to each other with the evaporimeter, and the low pressure circulation bucket passes through the refrigerant pump and links to each other with the evaporimeter, and the refrigerant pump passes through the pipeline and links to each other with oil return controlling means, and oil return controlling means.
The utility model has the advantages that: the oil return control device is arranged on a bypass pipeline at the outlet of the pump liquid supply refrigeration system, and the liquid refrigerant containing lubricating oil enters the oil return control device through the H-inlet ferrule joint, enters the outlet ferrule joint after being limited by the flow limiting orifice plate, and finally is connected with the air suction pipeline of the compressor and enters the air suction port of the compressor.
