The standby power system is a liquid cooled, commercial lp generator with block heater and battery warmer, installed to the standard of an emergency power system.
I'm somewhat skeptical about the freeze protection provided by the chiller manufacturer for hydronic components inside the chiller...
Using antifreeze of sufficient strength for burst protection is a common approach to providing freeze protection, but there are many applications where active freeze protection is relied on exclusively. Open and closed circuit cooling towers, as well as evaporative refrigerant condensers are...
If the discharge air from the desiccant wheel was added back in before the main cooling coil, than the amount of moisture that could be removed by that coil would be reduced. Using a separate coil for sensible post-cooling of the active desiccant wheel air stream will result in dryer leaving air...
I'm concerned about the risk of freezing damage occurring on a packaged air cooled scroll chiller. The unit was spec'd with factory provided heater for it's brazed plate heat exchanger, and heat tracing for the hydronic pumping package. The manufacturer claims the unit will be protected to...
