Abstract

A water heating system using waste head of boiler flue gas and an air-source heat pump unit comprises a fuel hot water boiler, a boiler flue and a hot water tank, wherein a flue gas heat exchanger is arranged on the boiler flue. Cold water flows to the flue gas heat exchanger through a water inlet valve and flows out of the flue gas heat exchanger through a water outlet valve after heat exchanging; the water from the flue gas heat exchanger is fed to the air-source heat pump unit through a booster pump; an electrically regulating outlet valve of the air-source heat pump unit is connected with a water inlet valve of the hot water tank; the air-source heat pump unit further heats the hot water from the flue gas heat exchanger; and the hot water flows to the hot water tank, then flows outside from the water outlet valve of the hot water tank. By recycling the waste heat of the boiler flue gas and using the air-source heat pump to supply domestic hot water, the water heating system overcomes the disadvantages in heating water by using the hot water boiler or the air-source heat pump unit independently, thereby solving the problem of fuel deficiency in winter, improving the energy efficiency of the air-source heat pump unit, and lowering the production cost of domestic hot water.

Background technology
Existing hotel produces the domestic hot-water and uses hot-water boiler separately or use net for air-source heat pump units to produce life hot water separately, but the employed fuel cost height of hot-water boiler, and winter diesel oil or the supply of fuel such as natural gas relatively more nervous, fuel is more difficult to get assurance sometimes; And contain a large amount of energy of utilizing of not obtaining in the boiler smoke, its exhaust gas temperature up to 120-200 ℃ between, cause the thermal efficiency lower, the hot water cost is higher; Boiler generally is installed on basement in addition, and the temperature of basement is quite high; Make the operator at high temperature work for a long time the influence healthy.Use the air-source heat pump hot water group to produce hot water, this hot water unit only when summer, environment temperature was high efficiency higher, and when winter, environment temperature was low, its efficiency was lower, cause winter with the hot water amount when big the hot water amount be difficult to be guaranteed.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of residual heat from boiler fume and net for air-source heat pump units hot-water heating system are provided, and to realize making full use of the surplus horse reins of boiler smoke, improves the thermal efficiency; Can alleviate fuel anxiety in winter again, reduce the hot water production cost.
The utility model comprises fuel heat homogeneous solution-type reactor, boiler exhaust gas road, boiler, it is characterized in that: on the boiler exhaust gas road, be provided with a flue gas heat exchanger, cold water flows into through flue gas heat exchanger through water intaking valve and carries out heat exchange after the water that outlet valve flows out links to each other with net for air-source heat pump units by booster pump, the motorized adjustment outlet valve of net for air-source heat pump units links to each other with the boiler water intaking valve, net for air-source heat pump units further heats flue gas heat exchanger and flows through next hot water, enter boiler, flow out through the boiler outlet valve.
The outlet conduit of described net for air-source heat pump units is provided with cooling-water temperature sensor, is provided with environment temperature sensor near net for air-source heat pump units; Described cooling-water temperature sensor links to each other with the signal receiving end of environment temperature sensor with the PLC controller, the signal of PLC controller sends end and links to each other with forced draft fan with the motorized adjustment outlet valve, cooling-water temperature sensor and motorized adjustment outlet valve are chain and regulate the control leaving water temperature by the PLC controller, described environment temperature sensor and forced draft fan are chain and control by PLC, when environment temperature is lower than a certain setting value, the starting air-introduced machine is forced the high temperature air of distant place environment is caused net for air-source heat pump units, improves the efficiency of net for air-source heat pump units.
The bottom of described flue gas heat exchanger is provided with heat exchanger blowoff valve and condensed water drain valve.
Described booster pump entrance point is provided with filter.
Advantage of the present utility model: the fume afterheat of hot-water boiler is reclaimed, and produce the domestic hot-water in conjunction with net for air-source heat pump units, overcome independent use hot-water boiler or used net for air-source heat pump units to produce the shortcoming of life separately with hot water, alleviated boiler oil anxiety in winter, improved the efficiency of net for air-source heat pump units, reduced the production cost of life with hot water.
