Description
Technical field
The present invention relates to a kind of conditioner, the particularly a kind of low-temperature heat source of nature existence or conditioner that thermals source such as industrial exhaust heat, used heat promote compressor operation of utilizing.
Background technology
In the New Times that Chinese energy is changed, people are worrying for environmental protection, energy shortage, electricity shortage, the security of national energy strategy and the problems such as economy of using energy source.With the rich and influential family of ability, aircondition major part is in the market come the Driven Compressor running by electric power to aircondition beyond doubt.The aircondition that also exists some to utilize heat energy to drive, present on the market GHP gas heat pump air-conditioning for example is the compressor that utilizes gas engine to drive to be equipped in off-premises station.And there is a large amount of heat energy in occurring in nature, for example solar energy, geothermal energy etc., and in addition, a large amount of industrial exhaust heats, automobile waste heat are discharged in the air, and this not only causes the waste of the energy, also contaminated environment.For the utilization of this part heat energy, high temperature heat source generates electricity in also only limiting at present utilize, and the limitation of this way is that a large amount of low-temperature heat sources are not utilized effectively, and needs to consider the utilization of the electric power that sends, and problems such as transmission & distribution are incorporated into the power networks.
Summary of the invention
Be defective and the deficiency that overcomes prior art, the invention provides a kind of aircondition that utilizes low-temperature heat source.When the heating operation, compressor is not to rely on electric power to drive to this aircondition in refrigeration, but utilizes power set that a cover circulates based on organic Rankine to drive.The merit amount of this power set output is except being used for the Driven Compressor running, and unnecessary merit amount is used for driving generator and generates electricity, and the electric power that is produced can be supplied with consuming parts such as blower fan, thereby realizes the unregulated power running of aircondition.The present invention can effectively utilize discarded low-temperature heat source, alleviating energy crisis, and the power that produces directly is used to drive the running of aircondition consuming parts, get on the spot can, use on the spot, needn't consider the electric power transportation problem.
The present invention realizes through following technical scheme, comprises compressor main body, turbine and generator at the compressor of this conditioner, and compressor main body is piston type, vortex, rotator type, screw, a kind of in centrifugal.Compressor main body links to each other with turbine through linkage with generator.Said turbine is connected on the power set of a cover based on the organic Rankine circulation, and these power set comprise evaporimeter, turbine, condenser and circulating pump, through pipeline these four parts are linked to be the loop in order, and cycle fluid circulates in the loop.When power set are worked; The cycle fluid evaporimeter of flowing through, absorb the heat of external heat source after vaporization become high steam, the high steam acting of in turbine, expanding; The merit amount of output is used for the running of Driven Compressor main body, and unnecessary merit amount is used for driving generator and generates electricity.Steam after the acting becomes the exhaust steam of low-temp low-pressure, enters at last and is condensed into liquid state in the condenser, through circulating pump liquid refrigerant is sent into evaporimeter and carries out new circulation.Said evaporimeter is a heat-exchange device, and in this heat-exchange device, the origin of heat that cycle fluid absorbs is in the existing thermal source of nature, and for example solar energy, geothermal energy perhaps derive from industrial exhaust heat used heat etc.
Generator is connected with the systematic connection converter; After this systematic connection converter converts the three-phase alternating current from generator to direct current through the AC/DC converter; Be transformed into the three-phase alternating current of 220V again; Export to commercial system; This commercial system comprises source power supply, tie breaker and user load.The systematic connection converter is connected between tie breaker and the user load.In aircondition when running,, consuming parts runnings such as the electric power that generator sends and the blower fan that is used for driving aircondition and water pump realize that the aircondition unregulated power turns round.When aircondition shuts down; Through clutch compressor and turbine are broken off; The merit amount of turbine output can all be used for generator and generate electricity; At this moment; Turbine has the generating capacity corresponding with its driving force, and the electric power that sends is exported to commercial system through the systematic connection converter.
The invention has the beneficial effects as follows:
1. utilize discarded low-temperature heat source to come the Driven Compressor running, realize the running of aircondition unregulated power, and help energy-saving and emission-reduction.
2. the power of Chan Shenging directly is used for the Driven Compressor running, gets ability on the spot, uses on the spot, needn't consider the electric power transportation problem.
