An expert in chiller - Dongguan Jiusheng Machinery Co., Ltd. tells you the principle, cooling characteristics and energy saving methods of chillers:
Our range of quality products such as Air-cooled Chiller, Water-cooled Chiller, Screw Chiller and more are a great choice for you.
The main features of the chiller:
1. Compression refrigeration
1) Screw chiller: simple structure, few wearing parts, long service life, high single-stage compression ratio, and tend to replace piston type in the range of large and medium cooling capacity.
2) Piston chiller: The technology is relatively mature, with high efficiency and wide temperature range. It can be made into large, medium and small products of various specifications. It is the most widely used type of chillers.
3) Centrifugal chiller: The high-speed rotating impeller makes the refrigerant gas obtain kinetic energy, and then increases its pressure through the diffuser and cools and liquefies, throttling and refrigeration. It has the characteristics of compact structure, large cooling capacity of single machine, and energy regulation. Machines used for air conditioning mostly use R11 and R12 refrigerants.
2. Absorption refrigeration
The refrigerant is evaporated and cooled by the adsorption of the absorbent on the refrigerant. Commonly used are ammonia-water absorption chillers and lithium bromide-water absorption chillers, which use heat source as power, consume less power, run smoothly, less wearing parts, and have a large energy adjustment range. Types of chillers. Chillers are widely used in industry, so how can we make chillers save energy? We have to master two key points, one is to increase the evaporating temperature, and the other is to reduce the condensing temperature. Thereby increasing the transformation of the cooling tower to ensure the cooling water efficiency. In this way, high efficiency and energy saving can be achieved, which saves money for the industry. We should also pay attention to regular maintenance and maintenance when using the refrigerator, so as to prolong its service life.
