Central air conditioning system

This post was last edited by Strive with a smile on 2016-7-7 15:49. The high exhaust temperature of the compressor causes the equipment to shut down: 1. Is the high return air temperature of the compressor related to the thermal expansion valve? 2. Does a screw-type refrigeration compressor cause the motor to overheat? 3. Does scaling on the copper tubes of the condenser directly lead to excessively high exhaust temperatures, increasing the likelihood of equipment shutdown? 4. How can one determine when reverse expansion occurs? Since both the reverse expansion process and the inhalation process are very brief, can the temperature rise resulting from this process be ignored?
For the issue you mentioned, 1. first clean the condenser to see if that helps. No. 2: A low current level indicates a lack of refrigerant; these two problems have been basically resolved
If the expansion valve is damaged, the cooling effect will be extremely poor. It’s possible that it won’t cool at all
I’ve never heard of the term “anti-expansion.” A expansion valve is generally adjusted based on the temperature at the outlet of the condenser
