Thanks for the presentation - a good example of water cooled hvac is with boat heater and coolers that utilize sea water.

Right up my alley. I work on tons of WSHP'S, ERV HP's. Some of the tubes are also rifled as well for even better heat transfer and maximum contact time. We also have lots of plate and frame HXers.

I have a location with 3 walk-in boxes that a previous technician bypassed the air cooled condensers and installed coaxial water cooled coils. The water bill is through the roof. I’m sure the water regulator valves are wide open. How do I dial in the head pressure and save water? There isn’t a manufacturer spec sheet because this was a custom job. These are all r134a medium temp reciprocating compressors.

Go to change the run cap on one of those units. The coax coil starts leaking into the damn water.
-
Anyone ever seen an air condenser with a coaxial coil also attached ? So the refrigerant travels through the coaxial coil and then through a air cooled condenser and then to the evaporator.

Taking the fitting off the water lines on a 30 year old unit is a hole nother storyline. Some of the water piping in the buildings in los Angeles are like over 30 years old .

Hi Sir, how does the boiler trigger to supply hot water when there is a call for heating? TIA

What is the proper way to clean the coax coil, if there is glycol in the system

I'm running a service call tomorrow. Its a no heat and the original tech put in on the notes that the thermostat was not set up for heat pump. New tenants in an old space. Could this really be the case that it's not enegizing the reversing valve? The unit is suspended (little to no access) so I was just curious on what my first steps you would recommend?
