Abstract
A thermal-dynamic centrifugal water-source heat pump unit is a novel water-source heap pump unit with thermal-electric environment as the application platform and the steam turbine as mechanic power. The core elements of the unit include a centrifugal compressor unit driven by the steam turbine and a high ejection coefficient steam ejector. Through adjusting speed of steam turbine and indirectly linking the one adjustable outlet diffusers of the imported zero-grade adjusting guide blade, the flow of the compressor can be regulated, and the residual heat of the waste steam of the steam turbine can also be taken advantage of by steam ejector to realize second cascaded heating. The utility model adopts high-speed centrifugal compressor which enjoys high energy efficiency. The regulation during operation of the unit is more efficient and reasonable, the heating regulation range is wider and regulation range for working substance flow is extensive and the heating coefficient is obviously increasing.
Description
Technical field: the present invention is with high energy consumptions such as steam power plants, unnecessary thermal environment is a background, it is a kind of novel water source heat pump units, with steam or waste heat is power, with the steam turbine is machine power, promoting working medium with centrifugal compressor circulates in system, and the automatic speed regulation system by the original standard configuration of steam turbine is to the speed governing of steam turbine output shaft, and then indirectly link with import zero level variable vane-adjustable diffuser of outlet and realize Flow-rate adjustment to compressor, thereby a kind of device that utilizes waste heat realization secondary cascade such as exhaust steam in steam turbine to heat to finish heat-production functions (the compressor charge flow rate 〉=50m3/min).
Background technology: human residential space be unable to do without heat energy, and burn exactly each class A fuel A or consume of the conventional method of producing heat energy.Method with the low-rank fuel of burning as the coal heats, and not only will lose the basic energy resource of a large amount of bad regeneration, and very easily cause environmental pollution; And the high-quality like this energy of electricity consumption heats, convenient outwardly clean, but production process from electricity, bigger, more bad the tidying up of environmental pressure that electricity consumption heats the actual energy that is consumed and caused ... heat pump can be by consuming a small amount of high-quality energy, draw a large amount of low-quality heat energy, give the user the higher quality heat energy pump after synthetic.Experiment showed, that heat pump produces the basic energy resource that heat energy consumes and save one times even several times than traditional heating equipment.
Heat pump has mechanical compression heat pump (the invention belongs to this type), absorption heat pump, chemical heat pump, steam jet heat pump, thermoelectric heat pump etc. by the operation principle classification.At present, the source pump that heavy construction central air-conditioning project is adopted all is mechanical compression type heat pump and absorption heat pump mostly, the drive unit of its compressor mainly is motor, internal combustion engine and gas turbine, though centrifugal compressor heat pump dynamic balancing characteristic is good, vibrate little, the heating capacity adjustable range is big, life-span is long, but the centrifugal compressor gas channel is narrow, flow adjustment range (70-100%, Kang Puai company have DC speed regulation screw rod machine, and speed adjustable range is 20～100%) less than normal, surge takes place when condensing pressure is too high easily, makes heating efficiency low and unstable.
Summary of the invention: the present invention is to be application platform with thermoelectric environment, is the mechanokinetic water source heat pump units with the steam turbine.This source pump comprises: evaporimeter, the centrifugal compressor by Steam Turbine Driven, condenser (one-level heater), secondary heater, high mass ratio of induced-to-inducing air steam jet ejector, throttling expansion parts and circulating pump etc.Automatic speed regulation system by the original standard configuration of steam turbine is to the speed governing of steam turbine output shaft and then link with import zero level variable vane-adjustable diffuser of outlet indirectly and realize Flow-rate adjustment to compressor, and utilizes waste heat such as exhaust steam in steam turbine to realize that by high mass ratio of induced-to-inducing air steam jet ejector secondary cascade heats.
The advantage of the invention: increased the centrifugal compressor gas channel, flow adjustment range has obtained increasing substantially; Unit operation is steady, and stable work area (from stopping up point to pumping point) is well-to-do, and centrifugal compressor dynamic balancing characteristic is further enhanced, and complete machine oscillation is littler, moves more reliable; Regulating measure in the unit running process more effectively and reasonably; And the heating capacity adjustable range is wide, and the working medium flow degree of regulation is big; Using energy source is more reasonable, more economical, and utilization rate of waste heat is higher, and heating efficiency obviously strengthens, and machine life increases; Reduce the quality grade of power source.
Main technical detail is as follows:
Systematic working medium circulating pressure fluctuation range can remain on 1%-3%;
Flow adjustment range: 60-100%;
Operation noise: 85-90dB;
Heat regulation scope: 65-90 ℃;
Heating efficiency: 3.2-3.6.
