Read： 814 Time：20months ago Source：Transform the World with Simplicity

With the development of modern industry and the improvement of people's requirements for indoor comfort, the cold water system is one of the important components of modern construction equipment, and its requirements are getting higher and higher. The screw chiller as a high efficiency and energy saving cold water system, its application is more and more widely. So, what is its working principle?

1. screw chiller working principle

compressor is the core component of screw chiller, its structure is composed of the main screw and auxiliary screw two screw. The envelope on the main screw and the envelope on the secondary screw cooperate to form a "gas chamber", and there are multiple such "gas chambers" in the compressor to work, thus completing the compression process. The
is
in the chiller. After the refrigerant absorbs heat and evaporates in the evaporator, it is compressed by the compressor. The compressed high-temperature and high-pressure gas is cooled and cooled, and becomes liquid after heat transfer in the condenser, and then passes through the throttle After the valve is reduced in pressure and liquefied, it has been cycled back and forth to achieve the purpose of refrigeration.

2. Advantages of screw chillers

screw chillers have the following advantages over other cold water systems:

(1) High efficiency and energy saving: screw compressors have the characteristics of high efficiency and low consumption, and the unit cooling capacity during operation is more efficient than other compressors. At the same time, its cooperation with the control system also helps to realize the control of energy consumption.

(2) Good stability: the screw compressor runs smoothly, has low noise, and low maintenance cost; its structure is simple and strong, the failure rate is low, and the service life is relatively long.

(3) has a wide range of applications: it can be applied to refrigeration systems with constant temperature and humidity and high control accuracy. It is often used in commercial centers, industrial plants, office buildings and other places to meet the needs of different occasions.

3. screw chiller energy saving and maintenance

in order to improve the efficiency of screw chiller, improve energy saving effect, should pay attention to the following aspects of the work:

(1) control system upgrade: modern computer energy saving control system, can automatically adjust the cooling capacity and the transfer of cooling and heating load to adapt to reduce energy consumption.

(2) Optimization of heat dissipation equipment: The heat dissipation effect is directly related to the working efficiency of the screw chiller. It should ensure that the radiator pressure difference is small, the ventilation system is clean, and the energy consumption is reduced.

(3) Regular maintenance: regular maintenance is carried out every year, and the internal parts and equipment of the unit are checked and cleaned, which can reduce the failure rate and improve the stability.

conclusion:

screw chiller as a low energy consumption, good stability of the refrigeration equipment, widely used. However, in the process of use, we should also pay attention to its working principle and the maintenance of each part, so as to ensure its normal long-term operation and maximize its effectiveness. I hope that the introduction of this article can make everyone have a deeper understanding and understanding of screw chillers.
