50YEW Water-To-Water Design Features

The 50YEW 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 efciencies. 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.

The 50YEW 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-specic controls make the 50YEW series ideal for hydronic heating and domestic hot water generation. The heating-only refrigeration circuit is optimized for high water temperatures, heating efciencies, and capacities.

The dual level compressor isolation mounting system, insulated compressor enclosure, and compressor discharge mufer make the 50YEW series one of the quietest water-to-water heat pumps available. The attractive “Euro-style” cabinet allows the unit to t into any decor.

50YEW 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.
