1 Wellea Split System
1.1 System Schematic
Wellea is an integrated air-to-water heat pump system which is one-stop solution for space heating, space cooling and
domestic 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 hydro module with water tank. The heated water in the
hydro module circulates to low temperature heat emitters (under-floor heating loops or low temperature radiators)
to provide space heating. The 4-way valve in the outdoor unit can reverse the refrigerant cycle so that the hydro module
can provide chilled water for cooling using fan coil units. Because the water tank is integrated design in the hydro
module, so it can provide hot water directly to the users.
The heating capacity of heat pumps decreases with ambient temperature dropping. Backup electric heater is standard
equipped to provide additional heating capacity for use during extremely cold weather when the heat pump capacity is
insufficient.
