Description
Technical field
The utility model relates to a kind of water heater, particularly a kind of water heater that utilizes air source heat pump and water resource heat pump as thermal source.
Background technology
Utilize air source heat pump or the water resource heat pump water heater as thermal source, generally include water tank and heating unit, be provided with the hot-water circulation pipe between water tank and the heating unit, water pump is installed on the hot-water circulation pipe, water tank is provided with the hot water outlet pipe.Along with the hot water in the water-heater water tank constantly consumes, need in water tank, replenish the cold water (running water) that equates substantially with water loss.Traditional water supplementing method is directly to replenish running water in water tank, and this water yield arbitrary way has following defective: because there is the bigger temperature difference in the hot water in running water and the water tank, therefore the running water that directly replenishes can significantly reduce hot water temperature in the water tank, thereby bring influence for the normal use of water heater, be unfavorable for the continuous use of water heater, and the mixing of running water and hot water need reheat original hot water again, so both increased the heat time heating time of hot water, correspondingly increased the load of heating unit, the heater group leader time is moved, cause the increase of water heater energy consumption, can reduce the service life of heating unit again.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of water heater, and energy consumption is little, heating is fast, the characteristics of the big long-time continuous use of output but this water heater has, and the service life that can improve water heater.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of water heater, comprise water tank and heating unit, be provided with heat cycles pipe and following heat cycles pipe between water tank and the heating unit, on the following heat cycles pipe water pump is installed, water tank is provided with the hot water outlet pipe, it is characterized in that the hot-water circulation pipe between described water pump and the heating unit is provided with the automatic water supplement pipe.
As the utility model improvement of the technical scheme, on the described automatic water supplement pipe non-return relief valve is installed, between non-return relief valve and the hot-water circulation pipe automatic switch is installed.
As the utility model further improvement in the technical proposal, on the following heat cycles pipe between described water pump and the automatic water supplement pipe check-valves is installed.
As the further improvement of the utility model technique scheme, be provided with return pipe between hot water outlet pipe and the following heat cycles pipe, magnetic valve is installed on the return pipe.
In the above-mentioned water tank electric heating equipment is installed; Temperature measuring equipment is installed in the water tank.
The utility model can adopt press-bearing water tank, also can adopt non-press-bearing water tank.
Above-mentioned heating unit comprises compressor and imports and exports condensing heat exchanger and the evaporating heat exchanger that is connected with compressor respectively, the described port of export of heat cycles pipe down is connected with the cold medium entrance point of condensing heat exchanger, and the entrance point of last heat cycles pipe is connected with the cold media outlet end of condensing heat exchanger.
The beneficial effects of the utility model are: the utlity model has that the heating of little, the big unit of little water tank thermal losses is fast, water consumption is big, the continuous water supply amount is big and hot water service time is long and moisturizing and water synchronously with the characteristics of amount, heat unit short, unit long service life running time simultaneously, thereby can reduce the energy consumption of water heater, and overcome the mixed water problems of water tank for a long time, eliminate the heating that repeats that mixed water brings, reached real purpose of energy saving.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a flow chart of the present utility model.
The specific embodiment
With reference to Fig. 1, the disclosed a kind of water heater of the utility model, comprise water tank 1 and heating unit, wherein heat unit and comprise compressor 2, be connected with evaporating heat exchanger 3 on the inlet tube of compressor 2, between evaporating heat exchanger 3 and the compressor 2 low tension switch 4 is installed, on the outlet of compressor 2, is connected with condensing heat exchanger 5, between condensing heat exchanger 5 and the compressor 2 high-voltage switch gear 6 is installed.Water tank 1 both can adopt press-bearing water tank, can adopt non-press-bearing water tank again, and electric heating equipment 7 and temperature measuring equipment 8 are installed in water tank 1.
Between water tank 1 and heating unit, be provided with heat cycles pipe 9 and following heat cycles pipe 18, the port of export of following heat cycles pipe 18 is connected with the cold medium entrance point of condensing heat exchanger 5, the entrance point of last heat cycles pipe 9 is connected with the cold media outlet end of condensing heat exchanger 5, on the heat cycles pipe 18 water pump 10 is being installed down, can connect temperature detect switch (TDS) on the water pump 10, water tank 1 is provided with hot water outlet pipe 11 simultaneously, also is provided with automatic water supplement pipe 12 on the following heat cycles pipe 18 between water pump 1 and the heating unit.
As shown in the figure, non-return relief valve 13 is installed on automatic water supplement pipe 12, to prevent that hot water from flowing backward to the running water pipe network from the automatic water supplement pipe, between non-return relief valve 13 and the following heat cycles pipe 18 automatic switch 14 is installed, automatic switch 14 is provided with the automatic controls that connects with hot water outlet pipe 11, when the hot water outlet pipe was in user mode, automatic switch was opened, and running water directly flows to water tank and forms an additional hot water program after condensing heat exchanger heats.
On the following heat cycles pipe 18 between water pump 10 and the automatic water supplement pipe 12, check-valves 15 is installed, flows backward in the water tank from consumption to prevent running water.
Be provided with return pipe 16 between hot water outlet pipe 11 and following heat cycles pipe 18, magnetic valve 17 is installed on the return pipe 16, so that the hot water outlet pipe is when longer, the hot water in the hot water outlet pipe can be back to the hot-water circulation pipe and continue heating.
Operation principle of the present utility model is: heating FCL hot water behind design temperature for the first time, when using hot water, the automatic water supplement pipe is opened, and running water directly flows to water tank and forms an additional hot water program after condensing heat exchanger heats, and this moment, water pump was not worked; The warm water of heating enter can reduce behind the water tank with water tank in the temperature difference of hot water, thereby reach the purpose that energy-conservation and long-time continuous is used hot water, when water not, starting of pump station carries out the hot water of cyclic heating water tank, makes its water temperature reach design temperature.So repeat automatic conversion work.Water can heat by automatic startup heating unit when standby, enters water tank to prevent too much cold water.
