The pipeline of the fan coil of end is connected, and heating was provided for interior.
An at least water pump is using foregoing double dynamical water pump, other pump bodies in the freezing or cooling water pump
Double dynamical water pump or the pump body of single electric drive can be used.
Further, secondary waste heat recover is further included, wherein secondary waste heat recover uses air-water heat exchanger.Winter system
When hot, high-temperature flue gas or input the low-temperature flue gas come out from a waste-heat recoverer, the water of output that input engine is discharged
It is then connected with the water at low temperature of evaporator, can both improve chilled water temperature, and then improve the heating efficiency of heat pump unit, and can be with
The chilled water of low temperature is allowed further to reduce exhaust gas temperature, it might even be possible to allow the exhaust gas temperature of engine down to below temperature.Summer
Then the water side of waste-heat recoverer and freezing water route are cut off by water valve during refrigeration.
When air-conditioning thermic load is smaller, such as spring and autumn transition season, air-conditioner host or boiler many times are in intermittent duty shape
State, and freeze and continuously run always with cooling water pump；If using gas driven water pump as Air-conditioning Cycle water pump, although
Although the power of water pump is smaller with respect to air-conditioner host, when running continuously, it can successively add up to generate a large amount of waste heats, can subtract
The energy consumption of few air-conditioner host or boiler, it might even be possible to be started without, only need to continuously run double dynamical water pump, so that it may meet heating need
It asks.
Advantageous effect：
The invention discloses a kind of double dynamical water pump, water source heat pump system, main innovation point is as follows：
1. one of present invention innovation：It only also can heating with water pump
Any central air conditioner system cycled using water, all be unable to do without water circulating pump, and all water pumps all only possess promotion water
The function of body movement, water pump cannot be heated or generated heat in itself, it is necessary in addition using heat pump or boiler as heat source.
By the present invention, the water circulating pump in air-conditioning system is changed to double dynamical water pump, it is same in driving air-conditioning waterway circulating
When, the fume afterheat of gas driven water pump is very absorbed into air-conditioning water route, as air conditioning heat, although water pump is relatively empty
The power for adjusting host is smaller, but the water pump operation time is the several times of air-conditioner host run time, can be by small heat accumulation energy
Into big heat, the energy consumption of air-conditioner host can be reduced, when thermic load is smaller, such as spring and autumn transition season heating or even can not have to open
Dynamic air-conditioner host.
2. the two of innovation of the invention：The full heat utilization of fuel, system high efficiency；
The heat energy efficiency height of fuel, exhaust gas temperature is most notable index, during the heating of existing boiler, even if using efficient boiler,
Institute's smoke discharging also has more than 100 degrees Celsius；And what the present invention innovated is combined combustion gas flue gas with the cryogenic vaporizer of heat pump, in the winter
When season heats or even the flue-gas temperature of fuel can be allowed also lower than outside air temperature, can really realize the full heat utilization of fuel.
3. the three of innovation：Rotor simplifies when transmission flywheel, system.
By taking being linked in sequence of engine, generator, pump motor and pump body as an example, when individually using fuel driven water
When pumping the pump housing, pump body must first drive generator and pump motor, then drive pump body, though pump motor does not produce at this time
Lively power, generator also do not generate electricity, and rotor passively dallies, but are served as with buffering, surely between engine and pump body
Fixed inertial flywheel.
Compared with other using the system of engine and motor parallel, by motor point when by engine driving pump body
From although the friction of motor idle running, complicated, poor practicability can be reduced.And use the layout structure of mechanical series real
Existing engine direct drives pump body, and transmission efficiency is not only convenient for motor and pump body is operated alone, and also allows for engine independence
Power generation, makes whole device simple and reliable for structure, while can facilitate and graft existing and very ripe fuel generator and water pump pump
Body technique makes the present invention have good practicability.
4. the four of innovation：Generator, pump motor are transformed into antigravity bearing, system high efficiency.
When motor only makees transmission shaft and inertial flywheel, since rotor weight is heavier, certain friction energy loss can be generated, and
Due to using the structure of antigravity Exciting Windings for Transverse Differential Protection in motor, it will not only increase frictional force, can also reduce whole system instead
Frictional resistance.
By increasing extraction wire in generator or pump motor stator, isolated in stator winding top one group or
Multigroup winding is individually powered as antigravity Exciting Windings for Transverse Differential Protection, and to it, using stator core and rotor core, forms an energy
The electromagnet structure that rotor is up attracted by controlling electric current, enables electromagnetic attraction size to allow generator or pump motor
The horizontally-supported bearing of transmission shaft or together with suffered by the horizontally-supported bearing of engine and pump body transmission shaft straight down
Pressure reduces or is zero.
Since engine, generator, pump motor and pump body are horizontal installation, and the movement portion in four
Part, generator and the weight of pump motor rotor and transmission shaft are more with respect to what other component to be weighed, and bearing produces when transmission shaft rotates
Raw frictional force only it is related with the vertical radial pressure that bearing is born, and with the level of torque of pump body load and transmission shaft without
It closes, once the pressure reduces even zero, frictional resistance when bearing rotates will be substantially reduced, while vibrations can be reduced and made an uproar
Sound.
This plain bearing adds rotor and the frame mode of antigravity Exciting Windings for Transverse Differential Protection, energy similar with magnetic bearing structure
The gravity that bearing radial direction is born is made to reduce even to zero, is equivalent under weightlessness, acquisition is similar to magnetic suspension shaft
The effect held.
Due to using engine, generator, pump motor and the direct cascaded structure of pump body, at this time entire generator and
Pump motor not only into connection engine and the transmission shaft and flywheel of pump body, coupling device using during rigid connection or
When generator, pump motor, engine and pump body use same transmission shaft, engine and water pump can be supported by also becoming
The antigravity bearing of the pump housing itself transmission shaft, thus the entirety of this generation antigravity effect is named as antigravity bearing.
Generator or pump motor become bearing, and antigravity Exciting Windings for Transverse Differential Protection structure seems very complicated, but in fact and need not be
On generator and pump motor body again additionally increase component, bearing, rotor and stator be all generator and pump motor in itself
It is existing, simply by optimization stator winding, increase extraction wire, produce unique antigravity Exciting Windings for Transverse Differential Protection structure, make to have
Generator and pump motor become a huge antigravity bearing and a more good zero-g inertial flywheel, and cost
But there was only some thousandths of of magnetic suspension bearing, this is exactly the ingenious part of the present invention.
When generator or pump motor need to recover power generation and driving function, pass through the switching in antigravity control module
Unit switches over the lead of antigravity Exciting Windings for Transverse Differential Protection, and antigravity Exciting Windings for Transverse Differential Protection is restored to generator or water pump electricity immediately
In the stator winding of machine.
