Water to water reversible heat pump
The Water to Water heat pump alone is not capable of cooling the liquid as additional heat sources (eg well water, ground heat, etc.) are needed. The heat pump equipment is located inside the building. The heat generated by the heat pump is transferred to the building by a water transfer medium, where additional units (eg fan coil, air handling unit, etc.) can be used to produce the desired temperature conditions in the spaces. In terms of the operation of the Water to Water heat pump, we distinguish 2 types. For smaller and more intelligent solutions, the heat pump includes a shift valve, which in itself can reverse the direction of operation (cooling or heating). For larger systems, this shift must be built into the external hydraulic system and solved for shift control.
