Two-stage compressor refrigeration principle
The two-stage compressor refrigeration cycle generally uses two compressors, namely a low-pressure compressor and a high-pressure compressor. 1.1 The process of refrigerant gas increasing from evaporating pressure to condensing pressure is divided into 2 stages The first...Read more -
How much does it cost to build a cold storage?
How much does it cost to build a cold storage? This is a question frequently asked by many of our customers when they call us. Cooler Refrigeration will explain to you how much it costs to build a cold storage. The small cold storage adopts a fully enclosed or semi-herme...Read more -
How to judge whether the screw refrigeration unit is operating normally?
When the screw refrigeration unit is started, the first thing to know is whether the refrigeration system is operating normally. The following is a brief introduction to the content and signs of normal operation, and the following is for reference only: The cooling water of the condenser should b...Read more -
How to defrost the cold storage?
Combined with the example of cold storage engineering rectification, I will tell you the technology of cold storage defrosting. Composition of cold storage equipment The project is a fresh-keeping cold storage, which is an indoor assembled cold storage, consisting of two parts: a high-temperature...Read more -
How to make cold storage more energy-saving?
As we all know, cold storage consumes a lot of electricity, especially for large and medium-sized cold storage. After several years of use, the investment in electricity bills will even exceed the total cost of the cold storage project. Therefore, in the daily cold stor...Read more -
What’s application advantages and disadvantages of refrigeration compressors?
Semi-hermetic piston refrigeration compressor At present, semi-hermetic piston compressors are mostly used in cold storage and refrigeration markets (commercial refrigeration and air conditioners are also useful, but they are relatively less used now). Semi-hermetic pist...Read more -
How to choose refrigeration compressor？
1) The cooling capacity of the compressor should be able to meet the peak load requirements of the cold storage production season, that is, the cooling capacity of the compressor should be greater than or equal to the mechanical load. Generally, when selecting a compressor, the condensing tempera...Read more -
How to deal with the reverse rotation of the cold room compressor？
The refrigeration compressor is the heart of the entire refrigeration system and the most important in the refrigeration system. Its main function is to compress the low-temperature and low-pressure gas from the evaporator into high-temperature and high-pressure gas to provide the source power fo...Read more -
Cause Analysis of Cylinder Stuck Caused by Refrigeration Compressor？
1. Cylinder stuck phenomenon Cylinder stuck definition: It refers to the phenomenon that the relative moving parts of the compressor are unable to operate due to poor lubrication, impurities and other reasons. Compressor stuck cylinder indicates that the compressor has been damaged. Compressor st...Read more -
Do you know the layout and design principles of cold storage ?
Freon piping layout The main feature of Freon refrigerant is that it dissolves with lubricating oil. Therefore, it must be ensured that the lubricating oil brought out from each refrigeration compressor can return to the refrigeration compressor after passing through the...Read more -
What are the common causes of frosting in cold storage evaporators?
The air cooler is an important component of the refrigeration system of the cold storage. When the air cooler works at a temperature below 0°C and below the dew point of the air, frost begins to form on the surface of the evaporator. As the operating time increases, the frost layer will become th...Read more -
What are the steps of cold storage installation?
Cold storage project installation steps The construction and installation of the cold storage project is a systematic project, which is mainly divided into the installation of the storage board, the installation of the air cooler, the installation of the refrigeration un...Read more
