It could be the internal relief valve in the compressor. I wouldn't worry too much about it. Unless it causes problems.

Not related to the ssssssssssssssssssssssshhhhhhhhhhh noise
but what does an economizer do on a chiller?? or is it really a low ambient control

no, it is an economizer.

Economizer = Motor cooling

the Economizer is a refrigerant to refrigerant, compact
plate-type heat exchanger to maximize chiller capacity
and efficiency by subcooling liquid refrigerant
delivered to the cooler expansion valve.
