Advantageous effect：

The utility model discloses a kind of serial power handpiece Water Chilling Units.

The utility model simplifies the cold-electric-thermal co-generation system being widely used at present, improves system effectiveness, and reduction accounts for Ground area, and wide adaptability make full use of external electrical network time-of-use tariffs, can reduce operating cost, while can also improve summer The stability of external electrical network allows combustion gas and electric power to realize have complementary advantages, while Dual-energy source system is more safe and efficient.This practicality is new Type main innovation point is as follows：

1. one of the utility model innovation：Rotor simplifies when transmission flywheel, system.

When only heat power machine being used to drive compressor, the prior art thinks that motor is to no avail at this time, is generally used multiple Motor and heat power machine and compressor are detached from by miscellaneous device, and in the present invention by the mechanical, electrical machine of heat power and compression Machine three's transmission shaft is directly connected, when individually using combustion gas refrigeration, heat power machine must first driving motor, then drive compression Machine, at this time motor neither generate power nor generate electricity, seem extra, completely outstripped the common usage of motor, however by right The reapective features of the mechanical, electrical machine of heat power and compressor are found after having done in-depth analysis：

The compressor of air conditioner cold water unit, especially high-power handpiece Water Chilling Units all use centrifugal compressor, centrifugal compressor Interior wheel speed is up to more than 10,000 turns, and internal structure cooperation is very accurate, to the stationarity of transmission shaft, i.e. axial vibrations and diameter It is required to vibrations very high.

Heat power machine it is more common have internal combustion engine, gas turbine, steam turbine, wherein hot internal-combustion engine rotational speed is relatively low, by multiple Piston-cylinder is alternately pushed and is compared with motor drive, and output torque has certain pulsating nature, there are a certain amount of axial direction and Radial vibrations, even will appear pinking sometimes；Gas turbine and turbine speed are higher, but in operation load variations when be difficult Avoid existing surge phenomenon, output shaft that from will necessarily also having strenuous vibration.

If therefore directly driving centrifugal compressor with heat power machine, under prior art, due to heat power machine be unable to reach with The same stationarity of motor, the components such as quick runner, high-speed bearing will be unable to bear heat power machine in air-conditioning centrifugal compressor Vibrations, and air-conditioning centrifugal compressor itself also will appear surge at low load, can also influence heat power machine in turn Safe operation, this is also one of the reason of technology is currently without real application.

However increase the motor of a Same Efficieney in the utility model between compressor of air conditioner and heat power machine, due to Motor stator winding open circuit, no current, for stator to rotor without torque, rotor is in free state, when the engine that is heated drives, only Only a small amount of rotor bearing frictional force.Simultaneously when the passive high-speed rotation of rotor, it is equivalent to dynamic in compressor of air conditioner and heat Increase an inertial flywheel between power machine, and by two groups of bearings before and after electric motor units, can firmly locked rotor axial direction Displacement is dynamic and radial displacement, can just fully absorb the vibrations of heat power machine, ensure to input to the torque of compressor axial and Radial is steady, is isolated to form good buffering with heat power machine in compressor, stationarity can reach straight with motor Drive compressor of air conditioner equivalent effect.Therefore seem the way for not conforming to convention, be built upon in fact really understand centrifugal compressor, Used best-of-breed technology scheme on the work characteristics basis of the mechanical, electrical machine of heat power is the innovation place of the utility model.This Though when do not use the electrical characteristic of motor routine, the mechanical structure of motor is cleverly utilized, makes rotor passively empty Turn, is served as between heat power machine and centrifugal compressor with buffering, the inertial flywheel stablized.

Relative to the system that other use engine and motor parallel, when engine driving compressor, detaches motor, though The friction of motor idle running, but complicated, poor practicability can so be reduced.And the layout structure of mechanical series is used to realize that heat is dynamic Power machine direct-drive compressor carries, and transmission efficiency is not only convenient for motor and compressor is operated alone, and also allows for engine Independent Power Generation, Keep whole device simple and reliable for structure, while can facilitate and graft existing and very ripe fuel generator and the airborne skill of compression Art makes the utility model have good practicability.

The two of the utility model innovation：Motor is transformed into anti-gravity bearing, system high efficiency.

When motor only makees transmission shaft and inertial flywheel, since rotor weight is heavier, certain friction energy loss is will produce, and Due to using the structure of anti-gravity Exciting Windings for Transverse Differential Protection in motor, it will not only increase frictional force, can also reduce whole system instead Frictional resistance.At this time by increasing extraction wire in motor stator, isolated in stator winding top one or more groups of Winding is individually powered as anti-gravity Exciting Windings for Transverse Differential Protection, and to it, and using stator core and rotor core, forming an energy will turn The electromagnet structure that up attracts of son enables electromagnetic attraction size to allow the level of electric motor units transmission shaft by controlling electric current Spring bearing reduces together with the pressure straight down suffered by the horizontally-supported bearing of heat power machine and compressor transmission shaft or is Zero.

Since the mechanical, electrical machine of heat power and compressor are horizontal installation, and the moving component in three, rotor Opposite other component to be weighed more with the weight of transmission shaft, what the frictional force that bearing generates when transmission shaft rotates only was born with bearing Radial pressure is related straight down, and unrelated with the level of torque of compressor load and transmission shaft, once the pressure reduces even It is zero, frictional resistance when bearing rotates will be substantially reduced, while vibrations and noise can be reduced.

This plain bearing adds the frame mode of rotor and anti-gravity Exciting Windings for Transverse Differential Protection, energy similar with magnetic bearing structure So that the gravity that bearing radial direction is born is reduced even to zero, is equivalent under weightlessness, acquisition is similar to magnetic suspension shaft The effect held.Since using motor and heat power machine and the direct cascaded structure of compressor, entire motor is not only at connection at this time The transmission shaft and flywheel of heat power machine and compressor when coupling device is using rigid connection, or work as motor, heat power machine and compression When machine uses the same transmission shaft, also become the anti-gravity bearing that can support heat power machine and compressor itself transmission shaft, thus This entirety for generating anti-gravity effect is named as anti-gravity bearing.

Motor becomes bearing, and anti-gravity Exciting Windings for Transverse Differential Protection structure seems very complicated, but does not need in fact on motor body again Additional to increase component, bearing, rotor and stator are all that motor itself is existing, simply by optimization stator winding, increase and draw Conducting wire produces unique anti-gravity Exciting Windings for Transverse Differential Protection structure, and making to have motor becomes a huge anti-gravity bearing and one more Good zero-g inertial flywheel, and cost only have magnetic suspension bearing some thousandths of, this be exactly the utility model it is ingenious it Place.When motor needs to make in electric motor mode or generator mode, by the switch unit in anti-gravity control module, to anti- The lead of gravity Exciting Windings for Transverse Differential Protection switches over, and anti-gravity Exciting Windings for Transverse Differential Protection is recovered immediately to the stator winding of motor or generator In.

The utility model has advantage following prominent：

1. reducing operating cost, perfection realizes that combustion gas is complementary with power price.

For much use tou power price user, when daytime power grid be in wave crest, when electricity price is high, more passed through using combustion gas When Ji, pass through gas driven air-conditioning or power generation；When night power grid is in wave crest, when electricity price is relatively low, pass through electric power and motor driving Air-conditioning.It can not only lower user's operating cost, but also pair can stablize network load, lower operation of power networks and administration fee.

2. reducing investment of equipment

Existing many central air conditioner users, such as hospital, hotel, megastore, central air conditioner room and generator are all Independent standard configuration can save user and buy generator unit expense, and the cost of erection of installation and computer room by the utility model With.

3. energy security, constructed Dual-energy source even multiple-energy-source framework, can reduce energy risk.

In occasions such as hotels of hospital, once having a power failure, gas driven this system may be used, not only can ensure air-conditioning just Often operation, moreover it is possible to further provide power supply for illumination etc.；When compressor of air conditioner and power generation are run simultaneously, generating electricity can also drive The auxiliary devices such as water pump, the wind turbine of central air conditioner system allow entire Air Conditioning Facilities that can be detached from external electrical network operation.The sky of building Load is adjusted to typically constitute from the 60-70% or more of building electricity consumption load, once air-conditioning system can not depend on external electrical network, in conjunction with this reality With novel generating function, just meaning whole building can not depend on external electrical network yet, while other than available natural gas, heat Engine can also use the energy such as fuel oil, bio-fuel, can greatly improve energy strategy safety in this way.

3. realizing the efficient utilization of the energy.

Combustion gas or fuel oil are converted into mechanical energy by the high-grade thermal energy that the burning of heat power machine generates, and directly drive compression Machine, generates a large amount of high-temperature residual heat flue gas and cooling water, and the recycling of supply absorption installation is freezed again.It adopts compared with the existing technology With combustion gas directly to unit refrigeration is absorbed, using energy source is much higher, thus has significant economic benefit and huge society Benefit.

4. operation simple in structure is flexible.

Cascaded structure makes simple system, by the simple switching of clutch, can realize plurality of operating modes in systems： （1）Compressor is operated alone by heat power machine；（2）Heat power machine is disconnected, compressor is operated alone by electric power by electric motor units； （3）Heat power machine and electrode unit drive compressor jointly.

In addition, under the cooperation of speed change gear, the matched well of compressor and a variety of actuating units can be realized, so that Each equipment can be operated in optimum state, realize economy and the stable operation of whole system.

Further, the utility model also has a variety of operating conditions, and therefore, flexibility is extremely strong.

In conclusion the serial power handpiece Water Chilling Units and serial power water chilling unit control method of the utility model are easy to real It applies, it is simple in structure.Operation is flexible, and energy utilization rate is high, is suitble to promote and apply.
