  Industrial chillers  can realize mutual switching, speed up production progress, reduce energy consumption, improve product molding efficiency, suppress product defects, and reduce the occurrence of defective products. Screw chillers are widely used in many fields such as electronics, rubber, plastics, papermaking, petroleum, chemical industry, food, machinery, brewing, vacuum coating, pharmaceuticals, etc., and are also widely used in places with centralized cooling to facilitate centralized management. In industrial manufacturing, chillers are crucial to the transfer of heat. However, many chiller ma chines are prone to poor heat dissipation after a period of actual operation. At this time, product maintenance should be carried out in a timely manner. First of all, let's clarify the signs of poor heat dissipation of the chiller. When the condenser of the chiller has poor heat dissipation, the efficiency of the compressor will decrease, and the operating current will increa...

  Both   air-cooled screw chillers   and   water-cooled screw chillers   use semi-hermetic screw compressors, and screw compressors have a high energy efficiency ratio. At present, the compressors of screw-type industrial chillers mostly use compressor brands such as Hanbell Bitzer, Fusheng, and Refcomp and other compressor brands. The main difference between the air-cooled screw chiller and the water-cooled screw chiller is the form of heat dissipation. The air-cooled screw chiller uses a fan to dissipate heat, uses air as the cooling medium, and dissipates heat through the air through a fin condenser and a low-noise fan. To cool the refrigerant, the water-cooled chiller uses water as the cooling medium, and then the cooling water cools the refrigerant. Secondly, the installation of the air-cooled screw chiller is simple and does not require a cooling tower. Because the screw chiller machine is relatively large, an external water tank is used. The air-cooled sc...

  There are many parts of the   screw chiller , among which there are several major components, namely the compressor, condenser, evaporator and microcomputer control system of the screw chiller. The operation panel and computer control system of the screw chiller are very important. Therefore, the four parts of compressor, condenser, evaporator and microcomputer control system are the core parts of screw chiller. Let us discuss these four components in detail. 1. Compressor As the name suggests, the screw chiller uses a semi-hermetic screw compressor as the compressor of the chiller. There are several major brands of screw compressors we use, such as Hanbell compressors from Taiwan, Bitzer compressors from Germany, or Fusheng compressors from Taiwan. These compressors have reliable quality, low failure rate and high energy efficiency ratio. In contrast to screw chillers, there are scroll chillers and piston chillers. The main brands are Copeland, Danfoss, Bitzer, etc. We won'...
