TranquilityWater-To-Water (THW) Design Features
TheTHW Series is unlike any other water-to-water heat pump on
the market today. The large operating map of the scroll compressor
allows high temperature operation,up to 145°F [63°C] leaving
load water temperature even at 32°F [0°C] entering source water
temperature. The combination of a coaxial (tube-in-tube) heat
exchanger for the source (ground loop) side and a brazed plate
heat exchanger for the load (heating/hot water) side provides very
high efficiencies. Integral controls for hydronic heating and domestic
water heating avoid the need for external microprocessor-based
controls for outdoor temperature reset, warm weather shutdown,
staging and other controls.
TheTHW has an extended range refrigeration circuit,capable of
ground loop (geothermal) applications as well as open loop (well
water) applications. Standard features and factory-installed options
are many. Unique application-specific controls make theTHW
series ideal for hydronic heating and domestic hot water generation.
The heating-only refrigeration circuit is optimized for high water
temperatures, heating efficiencies,and capacities.
ClimateMaster’s dual level compressor isolation mounting system,
insulated compressor enclosure,and compressor discharge muffler
make theTHW series one of the quietest water-to-water heat
pumps available. The attractive“Euro-style” cabinet allows the unit to
fit into any decor.

THW operating parameters are as follows: Min Source EWT = 20°F; Max Load LWT = 145°F (see application section for design guidelines).
Interpolation is permissible; extrapolation is not.
Operation below 40°F EWT (source) is based upon 15% methanol antifreeze solution.
All performance data is based upon the lower voltage of dual voltage units.
Antifreeze for source water is required for operation in the shaded area and all source EWTs below 40°F.
