Recently, many small partners are interested in water-cooled screw chillers. Let me ask the editor what is a water-cooled screw chiller. Water-cooled screw chillers are large and medium-sized refrigeration equipment that provide chilled water. Now everyone is following Shanghai Laofu Refrigeration Co., Ltd. Let's take a look at the company together.
Screw chillers are chillers with various types of screw compressors as the host. It is composed of screw refrigeration compressor, condenser, evaporator, thermal expansion valve, oil separator and automatic control
An assembled refrigeration device composed of components and meters. At present, screw chillers are being used more and more widely in the field of refrigeration and air-conditioning in my country, and their typical cooling capacity ranges are
700~1000kW.
advantage:
1. Simple structure, few moving parts, few wearing parts and long service life.
2, the circular motion is stable, and there is no "surging" phenomenon during low-load operation.
3. The compression ratio can be high, and the EER value is high.
4. It can be adjusted steplessly in the range of 10%~100%, with high efficiency under partial load and obvious power saving.
5. Not sensitive to wet stroke.
shortcoming:
1. The price is higher than the piston type. The capacity of a single machine is smaller than that of the centrifugal type, and the speed is lower than that of the centrifugal type.
2. The lubricating oil system is more complicated and consumes a lot of fuel.
3. The noise of the large-capacity unit is higher than that of the centrifugal type.
4. High processing precision and assembly precision are required.
The above are some of the advantages and disadvantages of water-cooled screw chillers compiled by Shanghai Raof Refrigeration Co., Ltd. I believe that everyone has a certain understanding of water-cooled screw chillers after reading this article. If you need more consultation, please call consult.
