Abstract
The invention relates to a refrigerating machine, refrigeration equipment or a system, in particular to a screw expansion scroll compressor. The technical scheme includes that the screw expansion scroll compressor is formed by the fact that a motor (26) is connected with an expansion machine (25) and the expansion machine (25) is connected with a scroll compressor (24), wherein the motor (26) is connected with a male rotor (13) of the expansion machine (25) through a motor output end (28), and the expansion machine (25) is connected with a compressor input end (31) of the scroll compressor (24) through a female rotor output end (29). The screw expansion scroll compressor has the advantages that a power source of the scroll compressor is increased, due to the fact that motive power of the expansion machine is from expansion work of carbon dioxide pressure drop, an energy resource of the screw expansion scroll compressor belongs to renewable energy sources and recycled energy sources, and through usage of the renewable energy sources, electric energy can be saved.
Description
Technical field
The present invention relates to F25B refrigeration machine on International Classification of Patents (IPC) through retrieval, and refrigeration plant or system's classification especially belong to the screw expansion scroll compressor.
Background technology
Reliability is high, noise is low, the energy-saving efficiency advantages of higher owing to having for scroll compressor, has been widely used in refrigeration, the industry of air compression and product for civilian use field.Its operation principle is that a pair of intermeshing whirlpool dish is arranged in screw compressor.The moving movable orbiting scroll that cries, the motionless quiet whirlpool dish that cries.Movable orbiting scroll is done the Plane Rotation motion with respect to quiet whirlpool dish, thereby forms the compression chamber of a plurality of variable volumes.When move to the central row outlet from the gas access of outside in these chambeies, the volume of compression chamber can little by little dwindle, thereby reaches the purpose of compression.Carbon dioxide is the refrigeration working medium of environmental protection, and the destruction of atmospheric ozone layer is zero, and is minimum to the greenhouse effects of the earth, is therefore present refrigeration and the air-conditioning system of environmental protection in the world with the carbon dioxide refrigeration of scroll compressor and air-conditioning system.But the energy saving of this system is also bad, and Energy Efficiency Ratio is lower, is necessary to improve structure and system, improves Energy Efficiency Ratio.There is following shortcoming in present carbon dioxide refrigerating system: 1, Energy Efficiency Ratio is low.Under general condition, the Energy Efficiency Ratio of the air-conditioning system of freon screw compressor can reach 4.0 left and right.But the Energy Efficiency Ratio of making the air-conditioning system of working medium of carbon dioxide only has 3.0 left and right.2, high critical point refrigeration system, carbon dioxide is difficult to fluidization, and under very high pressure, carbon dioxide is highdensity gas, and generally, the cooling pressure of carbon dioxide after reducing pressure by regulating flow, could produce liquid more than critical point.Above problem has retrained the application of carbon dioxide as cold-producing medium.
Summary of the invention
The object of the present invention is to provide a kind of screw expansion scroll compressor, solving the low shortcoming of Energy Efficiency Ratio that exists in existing scroll compressor and carbon dioxide refrigerating system technology, thereby widen this kind carbon dioxide coolant and refrigeration system thereof in the scope of application of power, the energy, refrigeration and field of air conditioning.
The technical solution used in the present invention is: it is to be connected with decompressor (25) by motor (26), decompressor (25) be connected with screw compressor (24) form; Wherein, motor (26) is to be connected with the male rotor (13) of decompressor (25) by motor output end (28); Decompressor (25) is to be connected with the compressor input (31) of screw compressor (24) by female rotor output (29).
Beneficial effect of the present invention is: 1, the present invention has increased the power source of scroll compressor.Because the power of decompressor is the expansion work of falling from pressure carbon dioxide, its energy is belong to the renewable sources of energy and reclaim the energy, can save electric energy for the use of the renewable sources of energy; 2, the present invention has increased the Energy Efficiency Ratio of scroll compressor carbon dioxide refrigerating system.Due to the recovery of expansion work, for same refrigerating capacity, the electric energy that this system is less with consumption rate, Energy Efficiency Ratio is the ratio of refrigerating capacity and system's wasted work of system, and therefore the carbon dioxide refrigerating system of screw expander is arranged with nothing relatively, its Energy Efficiency Ratio is much higher; 3, the present invention in concrete use procedure, can increase the function of regenerator in refrigeration system, and improves the refrigerating capacity of carbon dioxide unit volume, has also improved the refrigerating capacity of system simultaneously, has saved the energy.
