This post was last edited by YORK Industrial Refrigeration on 2017-9-2 at 08:42. Starting from now, in order to enhance communication among members, a \"Question of the Day\" activity has been launched on the Mechanical Equipment Technology forum. We hope everyone will participate actively to progress and improve together! ! ! Rewards: 3 wealth for active participation, 10-15 wealth for accurate answers. This question is valid for two days; no scoring will be given after that. Question: When the temperature of the cooling water is normal, which parameters can indicate the efficiency of heat exchange in the condenser, and how should they be interpreted? http://down.hcbbs.com/attachment/forum/201708/30/093407merrieo4fozdjrt4.jpg Answer: Small temperature difference; outlet water temperature – exhaust gas superheat ================================ Promotion: Petrochemical sector – “Creative Ideas for Energy Saving” 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)

Temperature of cooling water inlet and outlet connected to the condenser

By observing the exhaust pressure, it can be seen that the condenser is not working effectively; little gas is liquefied, so the pressure rises compared to normal levels
Reply #42017-08-31
High and low pressures increase, as well as the temperature of the chilled water

You can directly check the water temperature of the cooling water as it enters and exits.
Reply #62017-08-31
Observe the exhaust pressure and the temperature difference between the inlet and outlet of the cooling water
Reply #72017-08-31
Exhaust pressure. The greater the pressure, the worse the heat exchange efficiency
