Background technology
Along with being widely used of automobile, the energy of automobile consumption and the pollution that is caused are present social urgent problems.The engine of selling automobiles is the internal combustion engine of oil firing in the market, and the heat energy of fuel oil utilizes 40% at most, and remaining 60% cooling and smoke evacuation system through automobile is discharged in the atmosphere, has caused energy waste and environmental pollution.And the air-conditioning system of automobile refrigeration also need increase fuel oil again so that energy to be provided.Automobile refrigerating is directly to be driven by engine with compressor at present, or uses driven by motor.According to calculating, automotive air-conditioning system increases vehicle fuel amount 10-20%, and engine output reduces 10-12%.Utilizing the engine exhaust heat refrigeration also not have mature technology, some colleges and universities and R&D institution to carry out utilizes the absorption or absorption type refrigerating and the spray type refrigerating of waste heat all also to be among the research.
Summary of the invention
For solving the problems of the technologies described above, the present invention propose a kind of capable of being industrialized with the automobile engine residual heat refrigeration method and realize the device of this method, the contents are as follows:
A kind of method of utilizing the automotive residual heat refrigeration absorbs automotive residual heat heating low boiling point working medium through heat exchanger, drives refrigeration compressor through decompressor, realizes steam compression type refrigeration;
The present invention also discloses a kind of said device that utilizes the method for automobile engine residual heat refrigeration of realizing; Comprise drive system and cooling cycle system, said drive system comprises heat exchanger, decompressor, condenser, reservoir, working medium pump and lower boiling power working medium; Said heat exchanger, decompressor, condenser, reservoir, working medium pump connect successively; Said cooling cycle system comprises refrigeration compressor, evaporimeter, condenser, expansion valve and refrigeration working medium; Said heat exchanger absorbs automotive residual heat and heats lower boiling dynamic medium, drives refrigeration compressor, the said cooling cycle system of said driven compressor through decompressor;
According to different situations, said power working medium is identical with refrigeration working medium; Said power working medium also can be different with refrigeration working medium, and correspondingly, said drive system and cooling cycle system are provided with a cover condenser, reservoir separately;
Said decompressor is a piston type, also can be rotary.
Advantage of the present invention is: utilize automotive residual heat to realize New Refrigerating Cycle, when the decompressor fluid inlet temperature was 90 ℃, its thermodynamic coefficient can reach about 1.0, was higher than absorption refrigeration and spray type refrigerating.Use the decompressor of low boiling working fluid, volume is little, and body is firm, is fit to be installed on the automobile fully and has realized the effect of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
The specific embodiment
Specify the present invention below in conjunction with accompanying drawing, as shown in Figure 1, the present invention includes drive system and cooling cycle system, said drive system comprises heat exchanger, decompressor, condenser, reservoir, working medium pump and lower boiling power working medium; Said heat exchanger, decompressor, condenser, reservoir, working medium pump connect successively; Said cooling cycle system comprises refrigeration compressor, evaporimeter, condenser, expansion valve and refrigeration working medium; Said heat exchanger absorbs automotive residual heat and heats lower boiling dynamic medium, drives refrigeration compressor, the said cooling cycle system of said driven compressor through decompressor;
According to different situations, said power working medium is identical with refrigeration working medium; Said power working medium also can be different with refrigeration working medium, and correspondingly, said drive system and cooling cycle system are provided with a cover condenser, reservoir separately;
Said decompressor is a piston type, also can be rotary.
The present invention utilizes engine exhaust heat heating low boiling working fluid, and its pressure and temp is raise, and its elevated pressure temperature value is different different with working medium.Utilize the power working medium of the high pressure source that is used as power, through the decompressor expansion working, Driven Compressor work.
The present invention utilizes the low boiling dynamic medium to drive, the refrigeration system of decompressor Driven Compressor, and the critical piece of its cooling cycle system, like evaporimeter, condenser, expansion valves etc. are identical with conventional refrigeration.The low boiling point working medium decompressor can be shuttle, also can be revolving.Shuttle have a piston steam engine, and revolving have Wiper blade type decompressor, a vortex type decompressor etc.The structure of these equipment all is ripe.
Above-mentioned New Refrigerating Cycle, when the decompressor fluid inlet temperature was 90 ℃, its thermodynamic coefficient can reach about 1.0, was higher than absorption refrigeration and spray type refrigerating.Use the decompressor of low boiling working fluid, volume is little, and body is firm, is fit to fully be installed on the automobile.
Refrigeration system power working medium of the present invention and refrigeration working medium can be used with a kind of working medium, also can use different working medium.What use among the embodiment shown in Figure 1 is with a kind of working medium, if with different working medium, the condenser of working medium, reservoir should be two covers.Power working medium of the present invention can adopt R134a, R152a etc.
Decompressor in the embodiment of the invention and compressor can be reciprocating type or revolving.Adopt reciprocating expansion engine can adopt piston expansion engine, rotary expander has sliding vane type expander, Worm type decompressor etc.; These decompressors, compressor all can market purchasings.
Decompressor in this example and compressor and heat exchanger need to select according to automobile exhaust amount and refrigeration working medium.
