Starting from now, in order to enhance communication among users, a 【Daily Question】 activity has been launched on the Mechanical Equipment Technology forum. We hope everyone will participate actively to progress and improve together! ! ! Rewards: 3 points for active participation, 10-15 points for correct answers. This question is valid for two days; no scoring will be given after that period. As mentioned in the previous section, oil content was discussed. Please look at the diagram below: What type of refrigeration equipment is this? What are the differences between the two diagrams below, and what are their respective names? What is its function? What is the principle? Both are oil coolers; the one above uses a siphon oil cooling system, where the oil flows through the tube side while the refrigerant flows through the shell side. The oil used in this siphon oil cooling system comes from a siphon tank, and it is the density and flow rate that enable heat exchange between the liquid refrigerant and the oil, with the gaseous refrigerant being sent back to the siphon tank. Below is water-cooled oil cooling, with water flowing in the tube side and oil flowing in the shell side. ================================ High-quality promotions: Mechanical equipment——Maintenance procedures for York screw compressors https://bbs.hcbbs.com/thread-1806833-1-1.html Mechanical equipment——Upgrading of York Quinton control centers https://bbs.hcbbs.com/thread-1804837-1-1.html Mechanical equipment——Major repairs for GEA Grasso screw compressors https://bbs.hcbbs.com/thread-1800467-1-1.html Mechanical equipment——Disassembly and maintenance of British HOWDEN screw compressors https://bbs.hcbbs.com/thread-1832529-1-1.html Mechanical equipment——Disassembly and maintenance of Japanese Maekawa MYCOM screw compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1786445
