Installation and commissioning of cold st...
Assembly and installation of refrigeration unit 1. Both semi-hermetic or fully-closed compressors should be equipped with an oil separator, and an appropriate amount of oil should be added to the oil. When the evaporation temperature is lower than -15 degrees, a gas-liquid separator should be ins...Read more -

The oil return problem of refrigeration compressors has always been a hot topic in refrigeration systems. Today, I will talk about the oil return problem of screw compressors. Generally speaking, the reason for the poor oil return of the screw compressor is mainly due to the gas mixing phenomenon...Read more -
Cold storage refrigeration compression cl...
Introduction to the types of refrigeration compressors in cold storage: There are many types of cold storage compressors. It is the main equipment in the refrigeration system. It converts electrical energy into mechanical work and compresses low-temperature and low-pressure gaseous refrigerant in...Read more -
The effect of the cold storage is not goo...
The cooling capacity cannot meet the warehouse load requirements (low compressor efficiency) There are two main reasons for the lack of refrigerant circulation. First, the refrigerant charge is insufficient, and only a sufficient amount of refrigerant is needed at this time; Another reason is tha...Read more -

Freezing: The process of using the low temperature source generated by refrigeration to cool the product from normal temperature and then freezing it. Refrigeration: The operation process of obtaining a low temperature source by using the change of the physical state of the refrigerant to obtain ...Read more -
Defrosting operation mode of refrigeratio...
When the refrigeration equipment is running, the surface of the evaporative coil is prone to frost. If the frost is too thick, it will affect the cooling effect, so it needs to be defrosted in time. For the defrosting operation of low temperature refrigeration equipment and medium temperature ref...Read more -
What should I do if the freezer compresso...
Freezers are widely used in our daily life, and due to external and internal factors such as improper use or poor quality, freezers will have a series of failure problems. If the compressor stops after starting the freezer, the first thing to check is the cooling condition of the freezer. If the ...Read more -

I often go to a Yonghui supermarket for shopping, and found that the tally staff in the vegetable and fruit section of this store basically poured whole boxes of tomatoes, apples and other vegetables and fruits on the display table when restocking. Thinking of the exquisite fruit and vegetable di...Read more -
Factors that cause the temperature of the...
1. The frost on the surface of the refrigeration evaporator is too thick or there is too much dust, and the heat transfer effect is reduced Another important reason for the slow drop of the storage temperature is the low heat transfer efficiency of the evaporator, which is mainly caused by the ...Read more -
Reasons and solutions for the slow temper...
It is a common phenomenon that the temperature of the supermarket freezer does not drop and the temperature drops slowly. Now I briefly analyze the reasons for the slow temperature drop, hoping to bring some help to my colleagues in the work. 1. Due to the poor heat insulation or sealing perfor...Read more -
What are the methods to prevent ground cr...
When the length or depth of the cold storage is greater than 50m, an expansion joint should be installed. There are many large-scale cold storages. Since there is no expansion joint on the floor of the cold storage, the ground has a large area of cracks, which will cause the floor of the cold s...Read more
