The energy regenerating of existing mechanical system, improves system entirety efficiency.
When being recovered energy using the mechanical system of fixed drive ratio, the compressor 3 with the expanding machine 4 is more difficult accomplishes
Rated pressure and at a temperature of accurately flow matches, in order to solve the problems, such as flow matches, further, as shown in Fig. 2, can increase
The adjusting compressor 7 of one small flow in parallel with the compressor 3, so that only need to be by control when regulating system air quantity
System adjusts the revolving speed of the compressor 3, and the revolving speed of the expanding machine 4 is synchronous with the compressor 3 by the mechanical device of connection,
Difference in flow is supplemented by the adjusting compressor 7, and the flow for adjusting compressor 7 is adjusted according to outlet pressure, when pressure is more than
Reduce flow when rated range, increase flow when lower than rated range, to make the exhaust outlet of the compressor 3 and the expansion
Pressure between the air inlet of machine 4 is stablized in rated range.
Further, in order to improve system thermal efficiency, the compressor 3, the expanding machine 4, the adjusting compressor 7,
The heat exchanger and each connecting line, can be used adiabatic heat-insulation measure,
Further, the shell of the vacuum-pumping with Sealed sandwich can be used in the adiabatic heat-insulation measure, is improving insulation effect
While, system noise can also be reduced.
Further, to meet more healthy comfort needs, additional functions, including mistake can be increased in systems
Filter, disinfection, humidification, dehumidifying etc..
Further, in order to improve level of integrated system, whole system can be integrated into a single devices.
Further, the invention of the compressor 3 and the optional Publication No. CN107178494A of the expanding machine 4 are special
Rotatable blades pump/motor described in benefit, two coaxial Opposite direction connections, system is simple, and efficiency is high, can meet skill of the present invention comprehensively
The requirement of art scheme.
Beneficial effect
Technical solution of the present invention does not need refrigerant, only need to once exchange heat, and efficiency is high, and system is simple.
