Description

Waste heat recovery air source water heater
Technical field
The present invention relates to a kind of air source water heater that the hot water of discharge can be carried out waste heat recovery.
Background technology
Air source water heater is the product of scientific-technical progress in recent years and technological breakthrough, owing to air source water heater is heat pump principle of work, its heating efficiency is the several times that same power direct heating is obtained heat, thus can save a large amount of energy, it is widely used, and moves towards rapidly huge numbers of families.
Air source water heater have also been obtained more and more uses in public arena, such as large-scale bathroom, hotel and natatorium etc., owing to the air source water heater of public arena uses frequency height, thus using amount of hot water is very big, hot water still has a large amount of waste heats after using, and directly discharge is unfortunately.
We advocate energy-saving and emission-reduction, environmental protection and economy present stage energetically, if a kind of device can be designed, by waste heat recovery, can not only meet the policy of China's present stage energy-saving and emission-reduction, also can save a large amount of electric power and cost. But appoint in the manufacturing and designing of air source water heater waste-heat recovery device and so have many technical barriers do not broken through, carry out waste heat recovery it is crucial that utilizes waste heat to reduce the power consumption of water-heater, but the hot water enthalpy after using is low, temperature is low, heat recuperation is difficult, it is difficult to reach satisfied effect.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, it is provided that a kind of structure is simple, coefficient of heat transfer height, waste heat can be utilized effectively to reduce the air source water heater of power consumption.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of waste heat recovery air source water heater, comprise Heat exchanging water pot, Heat exchanging water pot top is provided with temperature sensor and heat exchange coil, temperature sensor is connected with heat pump main frame with heat exchange coil, it is characterized in that: a newly-increased auxiliary heat water storage tank, auxiliary heat water storage tank carries out pump circulation and is connected with Heat exchanging water pot top, connects loop and is provided with multiple hot water valve; Being provided with gutter channel near hot water valve, for collecting the spent hot water after use, gutter channel connects used heat tank, and used heat tank is connected with lift pump import, and lift pump exports through drip tray connection used heat water tank; Being provided with coil pipe in used heat water tank, coil pipe import connects water inlet pipe, and coil outlets connects Heat exchanging water pot.
Described Heat exchanging water pot and auxiliary heat water storage tank top are provided with vent valve, and bottom is provided with wash water valve. Vent valve can air in drain tank body, the space in tank body is fully utilized, wash water valve can carry out blowdown operation, discharges the dregs of bottom.
Described Heat exchanging water pot bottom is provided with into water splitter, water inlet splitter connects coil outlets, the water that the effect of water inlet splitter can make to enter in Heat exchanging water pot is different with temperature, the flow distribution that automatic generation exports up and down, is unlikely to upset the rule that water temperature in Heat exchanging water pot from top to bottom distributes. Because, heat exchange coil is positioned at the top of Heat exchanging water pot, and during heat pump host work, the distribution of heat exchange coil inner refrigerant condensing temperature is that upper height bends down, can ensure that in heat exchange coil and tank, water carries out adverse current high efficient heat exchanging like this, and the temperature in Heat exchanging water pot always keeps the rule that from top to bottom temperature reduces naturally. Inside and outside heat exchange coil, coil pipe, fluid heat transfer is all the high performance counter current heat exchange pattern in specialty, and recovery used heat is in optimal economic state, it is achieved low carbon runs.
Being provided with upflow tube in described used heat water tank, when waste water liquid level exceedes to a certain degree, the spent hot water that used heat water tank bottom temp is lower can be flowed out by upflow tube.
Used heat water tank bottom is inverted cone-shaped structure, and the cone end is provided with wash water valve, when the degree of cleaning of spent hot water are poor or residue is more, can open the dregs that bottom discharged by wash water valve.
Described water inlet pipe is provided with water intaking valve, and water inlet pipe also can lead directly to the bottom of Heat exchanging water pot.
It is provided with filter mantle in described used heat tank, avoids the damage lift pump of the solid particulate in used heat tank.
Described Heat exchanging water pot, auxiliary heat water storage tank, used heat tank and connecting tube thereof are provided with thermal insulation layer.
The workflow of the present invention is as follows:
The hot water that hot water valve is discharged, after using, enters used heat tank containing the spent hot water having surplus heat by gutter channel, is inputted the drip tray of used heat water tank by lift pump, and the existence of drip tray can make the from top to bottom NATURAL DISTRIBUTION of the hot water temperature in used heat water tank.
The overflow effect of upflow tube can constant level in certain position, like this can when water is excessive, by upflow tube discharge bottom cold water reduce thermal losses.
Open water intaking valve, the malleation of two water pot systems can be kept, just automatically fill into during hot water. When filling into, heated by spent hot water by the water of waste water tank coil pipe, then enter Heat exchanging water pot, it is achieved the waste heat recovery of spent hot water, greatly reduce the power consumption of water-heater.
Compared with prior art, the useful effect of the present invention is also:
During water heater working, open the pump between Heat exchanging water pot and auxiliary heat water storage tank, can ensure to open any hot water valve, hot water can be carried out rapidly, the waste of front-seat cold water of avoiding having a bath.
Device structure is simple and reliable, running cost is low, is particularly suitable for having a large amount of hot water have a bath and need the place consuming a large amount of hot water, can save a large amount of electric power; Perfect heat recuperation is combined with efficient countercurrent flow, promotes the energy-efficient feature of air source water heater further. The present invention is used for reality, it is possible to obtain good economic and social benefit, possesses stronger market outlook.
