Hi fine gents.
Here's the story. I have a 130kw heat pump water/water x2 circuits per heat pump. These heat pump use Sporlan BBIZE-15-GA TXV (TEV'S depending on which way you dress) and there are 2 per circuit inline (7/8 TEE then to TXV then to drier then TEE'd to 7/8). Having just changed the compressor I checked the bulb line and found the charge was gone. The compressor had burnt out. The question I have is this....If one of the TXV's on the same circuit (sharing common pipework) fails what would be the knock on effect? I am suspecting this is the reason the compressor failed and what happens is that by losing a TXV it is more or less a restriction. Problem is that the system does not act like its a restriction except for lower Delta T across the load heat exchanger.
Any ideas fine gents?
