The Chinese patent of " ZL201320753365.2 " discloses a kind of bathroom waste heat recovery heat pump hot-water heating system, and the structure utilizes two
Level heat exchange be cold water heat exchange and refrigerant heat exchange to absorb the heat in waste water, discharge after waste water heat release cooling, first waste water and certainly
Water is exchanged heat, and realizes that the first order exchanges heat, then waste water residual heat is further absorbed by refrigerant, for heating first order heat exchange
Current afterwards, make current heating turn into hot water, auxiliary heater is further heated to hot water when necessary, to reach user
Desired leaving water temperature.The structure preferably adds the recovering effect of waste water residual heat, auxiliary heating using two-stage heat-exchange method
The applicability of product, but the exactly live bad adaptability of two-stage heat exchange are also increased, its large area popularization and application, reason is constrained
It is that waste heat recoverer is built-in with two kinds of pipelines（Cold water pipe and refrigerant pipe）, it is more expensive to manufacture, installation difficulty is big, and dismount and remove
Fortune easily causes coolant leakage.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides the heat pump hot-water system that shunting strengthens backheat, its structure
Simply, production cost is low, is convenient to mount and dismount, and meets execute-in-place and application.
The technical solution adopted for the present invention to solve the technical problems is：
Shunting strengthen backheat heat pump hot-water system, including the first heat pump assembly, the second heat pump assembly, for heating water
The firing equipment of stream, the first water inlet stream and the second water inlet stream, first heat pump assembly include the of composition circulation loop
One compressor, the first condenser, first throttle device and the first evaporator, second heat pump assembly include composition circulation loop
The second compressor, the second condenser, second throttling device and the second evaporator, the first water inlet stream by the first condenser and
Second evaporator, the second water inlet stream is by the first evaporator, firing equipment and the second condenser, and the firing equipment is arranged on
Between first evaporator and the second condenser, the second water inlet stream is provided between the first evaporator and the second condenser
Apparatus for ultraviolet disinfection.
As the improvement of above-mentioned technical proposal, the firing equipment is the waste heat exchanger for absorbing used heat.
As the further improvement of above-mentioned technical proposal, the firing equipment is solar thermal collector.
Further, the two ends of the first water inlet stream mutually concatenate or separated.
The beneficial effects of the invention are as follows：The heat pump hot-water system of the present invention is provided with two heat pump assemblies and two bursts of feed water flows
Road, the current heat of the second water inlet stream is extracted by the first heat pump assembly, the current of the second water inlet stream is entered again after cooling
Enter firing equipment, enhance endothermic effect, the current heat of stream while the first heat pump assembly is intake the second of extraction is used for
Current in the water inlet stream of heating first, are then removed the heat that the first water inlet stream reclaimed water stream absorbs by the second heat pump assembly
The current for absorbing firing equipment heat are shipped to, heat utilization rate is high, while the current of the second water inlet stream are disappeared by ultraviolet
Malicious device sterilization, it is ensured that water safety, and because refrigerant is in two heat pump assembly internal circulation flows, heating is not entered and is set
Standby interior, simple in construction, production cost is low, substantially reduces installation difficulty and maintenance rate, meets execute-in-place and application.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
