It is an integrated air-to-water heat pump split system which is one-stop soluon for space heang, space cooling and domesc
hot water. The outdoor heat pump system extracts heat from the outdoor air and transfers this heat through refrigerant piping to
the plate heat exchanger in the hydronic box. The heated water in the hydronic box circulates to low temperature heat emiers
(under-oor heang loops or low temperature radiators) to provide space heang, and to the domesc hot water tank to provide
domesc hot water. The 4-way valve in the outdoor unit can reverse the refrigerant cycle so that the hydronic box can provide
chilled water for cooling using fan coil units.
The heang capacity of heat pumps decreases with ambient temperature dropping. Backup electric heater is customized to
provide addional heang capacity for use during extremely cold weather when the heat pump capacity is insucient.
