Starting from now, in order to enhance communication among users, a \"Question of the Day\" campaign 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. The control system of a chiller is crucial for the stability of the unit. We can get an idea of the system’s status from the several key parameters displayed on the home screen of the control cabinet. Which parameters, in your opinion, should definitely be shown on the home screen of a chiller? =============================== High-quality promotions: Mechanical equipment——Upgrade of York Quontum control centers https://bbs.hcbbs.com/thread-1804837-1-1.html Mechanical equipment——Summary of work by equipment managers for 2017 https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1881872 Mechanical equipment——Maintenance procedures for York screw compressors https://bbs.hcbbs.com/thread-1806833-1-1.html Mechanical equipment——Major overhauls of GEA Grauso 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 MYCOM screw compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=
