Advantageous effect：
The invention discloses a kind of heat power compressor, heat pump system and control method, main innovation point is as follows：
1. one of innovation：Rotor simplifies when transmission flywheel, system.
By taking being linked in sequence of engine, generator, motor and compressor as an example, when individually using fuel driven compressor
When, compressor must first drive generator and motor, then drive compressor, though motor does not generate power, generator at this time
Also do not generate electricity, rotor passively dallies, but is served as between engine and compressor with buffering, the inertial flywheel stablized.
Compared with other using the system of engine and motor parallel, by motor point when by engine driving compressor
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 drive compressor, transmission efficiency are not only convenient for motor and compressor are operated alone, also allow for engine and independently send out
Electricity makes whole device simple and reliable for structure, while can facilitate and graft existing and very ripe fuel generator and compressor skill
Art makes the present invention have good practicability.
The two of innovation：Generator, 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 motor stator, one group or more is isolated in stator winding top
Group winding is individually powered as antigravity Exciting Windings for Transverse Differential Protection, and to it, and using stator core and rotor core, forming one can be by
The electromagnet structure that rotor up attracts by controlling electric current, enables electromagnetic attraction size to allow generator or electric-motor drive
The horizontally-supported bearing of axis subtracts together with the pressure straight down suffered by the horizontally-supported bearing of engine and compressor transmission shaft
It is small or be zero.
Since engine, generator, motor and compressor are horizontal installation, and the moving component in four,
The weight of generator and motor rotor and transmission shaft is more with respect to what other component to be weighed, and what bearing generated when transmission shaft rotates rubs
It is only related with the vertical radial pressure that bearing is born to wipe power, and it is unrelated with the level of torque of compressor load and transmission shaft, once
The pressure reduces even zero, will substantially reduce frictional resistance when bearing rotates, while can reduce vibrations and noise.
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, motor and the direct cascaded structure of compressor, entire generator and electronic at this time
Machine not only into connection engine and the transmission shaft and flywheel of compressor, coupling device using during rigid connection or when generator,
When motor, engine and compressor use same transmission shaft, engine and compressor itself transmission shaft can be supported by also becoming
Antigravity bearing, thus by it is this generation antigravity effect entirety be named as antigravity bearing.
Generator or motor become bearing, and antigravity Exciting Windings for Transverse Differential Protection structure seems very complicated, but in fact and need not send out
Additionally increasing component on motor and motor body again, bearing, rotor and stator are all that generator and motor itself are existing,
Simply by optimization stator winding, increase extraction wire, produce unique antigravity Exciting Windings for Transverse Differential Protection structure, make have generator and
Motor becomes a huge antigravity bearing and a more good zero-g inertial flywheel, and cost only has magnetcisuspension
The some thousandths of that floating axle is held, this is exactly the ingenious part of the present invention.
When generator or motor need to recover power generation and driving function, pass through the switching list in antigravity control module
Member 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 motor immediately
In stator winding.
The three of innovation：With driven compressor compressor
For air-conditioning, many times need to operate in low load condition, are often compressed by frequently stopping compressor or control
The discharge capacity of machine is realized；But optimal mode is to reduce compressor electric motor frequency of supply, reduces the rotating speed of compressor electric motor, can obtain
Obtain Energy Efficiency Ratio most preferably.But the price of frequency converter is relatively expensive, complicated and reliability is controlled not as good as simple contactor.
Particularly with powerful compressor variable frequency device, price nearly close to Same Efficieney engine and generator total price, and
Change the rotating speed very simple of engine, also no at all increase any cost, be its basic function.
Existing engine and generator are made full use of in the present invention, by simply changing the engine in heat power compressor
Rotating speed just can easily change the working frequency of other compressors, simple and reliable.
In addition when compressor is used for high-speed permanent magnetic synchronous motor, such as centrifugal compressor, wheel speed is up to
15000-30000 r/min are arrived the 50 Hz or 60Hz supply frequencies promotion of external electrical network, it is necessary to using extraordinary frequency converter
250-500Hz, price are even more than the price of high-speed permanent magnet motor.And the present invention is used, by using high speed engine, such as
Gas turbine or the gear speedup case and High Speed Permanent Magnet Synchronous Generator for using technology very ripe, the 250- that can easily obtain
The power supply of 500Hz.
The present invention has advantage following prominent：
