Thread Content

Starting today, in order to enhance communication among those interested in marine equipment, we have launched the 【Daily Question】 initiative on the Mechanical Equipment Technology forum. We encourage everyone to participate actively so that we can all progress and improve together! ! ! Rewards: 3 wealth for active participation, 10-15 wealth for complete answers. This question is valid for two days; no scoring will be given after that. Question: Based on the diagram below, determine: the specific cooling capacity, the compression work, and the condensation heat; as well as the relationships among these three values! Answer: H1-H3, H2-H1, H2-H3. Condensation heat = Compression work + Cooling capacity ================================ Promotion activity: Petrochemical sector – “Creative Ideas for Energy Savings” campaign (the second phase is currently in progress). http://bbs.hcbbs.com/thread-1666758-1-1.html (Source: Haichuan Chemical Industry Forum) 2017 Coal Chemical Industry – “My Technical Upgrades”. http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Industry Forum)
