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 -
To do refrigeration, first understand the...
Refrigerant, also known as refrigerant, is the working substance in the refrigeration system. At present, there are more than 80 kinds of substances that can be used as refrigerants. The most common refrigerants are Freon (including: R22, R134a, R407c, R410a, R32, etc.), ammonia (NH3), water (H2O...Read more -
Refrigeration piston compressor does not ...
The compressor is a complex machine with high-speed operation. Ensuring sufficient lubrication of the compressor crankshaft, bearings, connecting rods, pistons and other moving parts is the basic requirement for maintaining the normal operation of the machine. For this reason, compressor manufact...Read more -
Parallel Refrigeration Unit Pipeline Dire...
1. Introduction of Parallel Refrigeration Units Parallel unit refers to a refrigeration unit that integrates more than two compressors into one rack and serves multiple evaporators. The compressors have a common evaporation pressure and condensation pressure, and the parallel unit can automatical...Read more -
What are the common reasons for the poor ...
1. Why the colder the weather, the worse the heating effect? Answer: The main reason is that the colder the weather and the lower the outdoor temperature, the more difficult it is for the air conditioner to absorb the heat of the air from the outdoor air environment, resulting in a relatively poo...Read more -
Screw refrigeration compressors are prone...
Screw refrigeration compressors are volumetric compressors. Since they have been used since 1934, due to their excellent performance, no wear and tear, and large unit cooling capacity, they have dominated small to large and medium-sized refrigeration systems. So what types of failures are prone t...Read more
