Comparison and advantages of carbon dioxi...
The refrigeration efficiency of carbon dioxide air conditioners is generally lower than that of common refrigerant systems under the same working conditions, and it is much lower. Whether heating can really be more efficient is doubtful. I have seen this statement in many places, but I don’...Read more -
What kind of “chain” is the c...
what is cold chain Cold chain refers to the special supply of certain products in the process of processing, storage, transportation, distribution, retail, and use, and all links are always in the specific low temperature environment necessary for the product to reduce loss, prevent pollution and...Read more -
How harmful are refrigerants to the human...
The refrigeration function of the air conditioner mainly relies on the refrigerant difluoromethane. Difluoromethane is odorless and non-toxic at room temperature, and generally has little effect on the human body. However, it is a flammable gas, and after being highly volatile, it may quickly for...Read more -
What should I do if the air conditioner l...
Condenser During the cooling process of the air conditioner, condensed water will inevitably be produced. Condensed water is generated in the indoor unit and then flows outdoors through the condensed water pipe. Therefore, we can often see water dripping from the outdoor unit of the air condition...Read more -
How to “save” soaked and damp...
Due to the impact of a series of climate changes such as the northward shift of the precipitation line and the impact of typhoons on land, some areas of my country have recently experienced extreme weather such as concentrated heavy rainfall, and many places have been hit by heavy rain. Some area...Read more -
Case Analysis of Chillers
The refrigeration host is referred to as a chiller, which is an important part of the data center air-conditioning system. The refrigerant is generally water, referred to as a chiller. The cooling of the condenser is realized by heat exchange and cooling of normal temperature water, so it is also...Read more -
Working principle of screw compressor and...
1. Compared with reciprocating piston refrigeration compressors, screw refrigeration compressors have a series of advantages such as high speed, light weight, small volume, small footprint and low exhaust pulsation. 2. The screw refrigeration compressor has no reciprocating mass inertial force, g...Read more -
Refrigeration people must understand the ...
1. Basic knowledge of central air conditioning 1. What is a refrigerant and what is its working principle? The working substance that transfers heat between the object to be cooled and the ambient medium, and finally transfers the heat from the object to be cooled to the ambient medium in ...Read more -
How to clean the refrigeration system of ...
Screw chillers can be divided into air-cooled screw chillers and water-cooled screw chillers according to different heat dissipation methods. The water-cooled screw chiller uses the cooling tower water circulation system to dissipate heat, while the air-cooled screw chiller uses finned air to dis...Read more -
Installation of cold storage specific imp...
1. The built environment (1) Before building the cold storage, the user is required to lower the floor of the cold storage area by 200-250mm, and prepare the floor; (2) Drainage floor drains and condensate discharge pipes are required to be left under each cold storage. There is no drainage floor...Read more -
The principle of multi-line cycle and the...
Compressed by the compressor, the original low-temperature and low-pressure refrigerant gas is compressed into high-temperature and high-pressure superheated steam, and then discharged from the exhaust pipe of the compressor. After the high-temperature and high-pressure gaseous refrigerant is dis...Read more -
The extremely cold winter is coming, come...
In winter, we not only need to protect ourselves from the cold and keep warm, but as refrigeration workers, we also have to “love and maintain” our refrigeration equipment, especially in the cold north. We must pay attention to the central air-conditioning and take precautions against...Read more
