When working under heating mode, the 4-way valve AB will be activated, so that the refrigerant will
circulate in reverse to the cooling process. The refrigerant gives out heats in indoor heat exchanger (Under
specific
conditions, the electric heating elements will start to work and give out heats). In the outdoor heat
exchanger, the refrigerant will absorb heat to perform heat pump heating cycle, so as to achieve the
purpose of heating.
When working under heating and hot water generation mode, the 4-way valve AB will be activated, so that
the refrigerant will give out heats in indoor heat exchanger and Hydro-box, but absorbing heats in outdoor
heat exchanger for heat pump heating and hot water generation cycle, thus to achieve the purpose of both
heating and hot water generation.
When working under hot water generation mode, the 4-way valve B will be activated, so that the refrigerant
will give out heats in Hydro-box, but absorbing heats in outdoor heat exchanger for heat pump heating and
hot water generation cycle, thus to achieve the purpose of hot water generation.
When working under cooling and hot water generation mode, the 4-way valve B will be activated as
needed, in which case the refrigerant will give out heats in Hydro-box, but absorbing heats in indoor heat
exchanger for cooling heating and hot water generation cycle. Under this mode, test may be done for
complete recycling of the heats. But when the water temperature is very high, only a part of heats can be
recycled. The system may identify according to reliable working range. In this way, the machine realizes the
purpose of both cooling and hot water generation.
