Dear friends,
We have designed a chiller unit with a Tecumseh CBP compressor, rating 750 BTU. Of the three machines, one machine is working fine. Other two machines are taking too long to cool. I have replaced the synthetic oil in the compressor with mineral oil as we are using hydro carbon as refrigerant. The variation in the parameters are as follows
Discharge line temp in OK machine = 65 deg Centrigrade immediately within 5 secs
Discharge line temp in problematic machine = 40 deg after 10 mins
Condenser air flow temp in OK machine = 42 Deg
Condenser air flow temp in problematic machine = 30 Deg
What I could understand is that the system is not throwing out enough heat, but could understand where is the problem.
Please suggest trouble shooting options
Thanks and regards
Giridhar
