【Mechanical Equipment Technology Edition】Daily Question 20170730: Identifying problems in refrigeration systems
Thread Content
Starting today, in order to enhance communication among those interested in marine equipment, we have launched the 【Question of the Day】 initiative on the Technical Forum for Mechanical Equipment. We encourage everyone to participate actively so that we can all progress and improve together! ! ! Rewards: 3 wealth for active participation, 10 wealth for correct answers. This question is valid for two days; no scoring will be given after that. Title: Refrigeration system – high pressure and high temperature on the high side, low pressure on the low side; bubbles present in the liquid supply sight glass. What is the reason? (Avoiding issues such as ice blockages, dirt blockages, and problems with the throttling mechanism) Answer: Content hidden in this post. Content hidden in this post. Content hidden in this post. Poor condensation performance (poor heat exchange efficiency of the condenser) ================================ Promotion event: Petrochemical sector – “Creative Ideas for Energy Saving” campaign (the second phase of this campaign 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)
The condensation effect is poor (the heat exchange efficiency of the condenser is low)
There is too little refrigerant, or there is air in it.
Fluoride deficiency or damaged compressor, etc.
Insufficient refrigerant; excessive system pressure difference
Some of the refrigerant evaporates in advance, resulting in a gas-liquid mixture
