Air-conditioning Cycle water pump although although the power of water pump is smaller with respect to air-conditioner host, when running continuously, can successively add up
A large amount of waste heats are generated, the energy consumption of air-conditioner host or boiler can be reduced, it might even be possible to be started without, only need to continuously run heat power water
Pump, so that it may meet heating demand.
When thermic load is larger, outside air temperature is relatively low, when using air source heat pump, as host, there are frequent defrost, heatings
The problem of effect is poor, and the flue gas of heat power water pump is introduced in net for air-source heat pump units surface cooler, solve the problems, such as defrost, Ke Yirang
The frostless operation of air-conditioner host.
For medium-and-large-sized air-conditioning system, pump power is larger, and the engine power of configuration heat power water pump is also larger, at this time
The net for air-source heat pump units configured in system is entirely the fume afterheat for absorbing heat power water pump, without being provided mainly for air-conditioning
Load, recycling hot water can converge in winter with air conditioning hot, share the load of the heating host such as boiler, and summer can carry for user
For free health hot water.
Further heat power water pump operation at operating mode 4 or 5, generate electricity can drive net for air-source heat pump units or its
His water pump, other water pumps i.e. but foregoing heat power water pump or common electric water pump；Entire Air Conditioning Facilities can so be allowed not
With external electrical network is completely dependent on, can work independently with natural gas or fuel oil.
The similarly above-mentioned heat pump system for including heat power water pump cannot be only used for summer system, the air-conditioning system of winter cold heating
System, can also use, whole year provides health hot water to the user as the hot water machine specially heated.
Advantageous effect：
This invention simplifies the cold-electric-thermal co-generation systems being widely used at present, improve system effectiveness, main innovation of the present invention
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 heat power 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.
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 air source heat pump, is heated in winter
When in addition the flue-gas temperature of fuel can be allowed also lower than outside air temperature, can really realize the full heat utilization of fuel, and air source heat pump
Also efficient frostless operation can be realized.
The three of innovation of the invention：Rotor simplifies when transmission flywheel, system.
The transmission shaft of engine, electric motor units and water pump is directly connected in the present invention, when individually using fuel driven water
During pump, gas engine must first drive generator and motor, then drive water pump, though motor does not generate power, generator at this time
Also do not generate electricity, rotor passively dallies, but is served as between gas engine and water pump with buffering, the inertial flywheel stablized.Relatively
In other using the system of engine and motor parallel, motor is separated when by engine driving water pump, although electricity can be reduced
The friction of machine idle running, but complicated, poor practicability.And the layout structure of mechanical series is used to realize the straight expelling water of gas engine
Pump, transmission efficiency are not only convenient for motor and water pump are operated alone, and also allow for gas engine Independent Power Generation, make whole device structure simple
It is single reliable, while can facilitate and graft existing and very ripe fuel generator and pump technology, there is the present invention good
Practicability.
The four of innovation of the invention：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 the pressure straight down suffered by the horizontally-supported bearing of engine and compressor transmission shaft
Power reduces or is zero.
Since engine, generator, pump motor and compressor 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 is only related with the vertical radial pressure that bearing is born, and with compressor load and the level of torque of 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 compressor, entire generator and water at this time
Pump motor is not only into connection engine and the transmission shaft and flywheel of compressor, and coupling device is using during rigid connection or when hair
When motor, pump motor, engine and compressor use same transmission shaft, engine and compressor itself can be supported by also becoming
The antigravity bearing of 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.
In conclusion the method for the present invention is easy to implement, it is simple in structure.Operation is flexible, and energy utilization rate is high, is suitble to popularization should
With.
