The invention discloses an energy-saving sanitary type
hot water supply system. The
system is mainly composed of a
solar heat collector, an air source
heat pump unit, a heat source control box, a heat source
circulating pump, a displacement
heat exchanger, a hot water sterilization device, a hot water
circulating pump, a control cabinet and a hot
water pipe network. The
solar heat collector is in parallel connection with the air source
heat pump unit, and the
solar heat collector and the air source
heat pump unit are each connected with a heat
source water supply
pipe for water inlet; a water returning part of the solar heat collector and a water returning part of the air source heat pump unit are each connected with a heat
source water returning
pipe; the heat
source water supply
pipe and the heat source water returning pipe are each connected with the arranged displacement
heat exchanger, and the displacement
heat exchanger comprises a first heat exchange unit and a second heat exchange unit; and the outlet water portion of the displacement heat exchanger is connected with the
hot water supply pipe, and the hot water sterilization device is arranged on the
hot water supply pipe. The energy-saving sanitary type hot
water supply system has the beneficial effects of being sanitary, energy-saving, efficient, safe,
environmentally friendly, good in using effect and the like, and the system is a centralized hot
water supply system which can be widely applied to houses, hotels, offices, markets, bath centers and the like.
