Dear All,

I have two identical system, the only diffenece i am finding is the TXV, as

Following are the observations,

1. The Suction temp. and pressure are higher as

System #1 System #2

20°C 28°C

2. The Eva. temperature is also on the high side as

System #1 System #2

3°C 10°C

Rest all parameters are same in both the systems


Can you suggest what all possibilities are there?

Thanks
Amit Saxena

Very likely there is less airflow through the condenser in system #2.

What are the entering and leaving air temps on both systems?

is the heat load a bit lower in one room?
