Description
Technical field
The present invention relates to refrigeration technology field, more particularly to a kind of heated type cooling cycle system.
Background technology
Carnot cycle is the ideal thermodynamic cycle carried out between the constant temperature thermal source that two temperature differ, and ideal refrigeration is followed
Ring is inverse Carnot cycle.Fluid refrigerating cycle includes four steps, adiabatic compression：Cryogenic gaseous refrigerant adiabatic compression temperature liter
It is high；Isothermal heat release：High temperature liquid refrigerant isothermal releases heat to high temperature heat source, is condensed into liquid refrigerant；Adiabatic expansion：It is high
Warm liquid refrigerant adiabatic expansion temperature reduces；Decalescence：Low temperature liquid refrigerant isothermal absorbs the heat of low-temperature heat source, steams
Send out into gaseous refrigerant；This fluid refrigerating cycle being made up of two constant temperature process and two adiabatic process is that inverse Kano is followed

Degree is also down to evaporating temperature；Refrigerant after throttling arrangement throttles enters evaporator, absorbs surrounding medium (air or water)
Heat, boiling vaporization, it is changed into dry saturation refrigerant vapour, then flows into compressor, into circulates next time.Thus constantly follow
Ring, so as to complete transmission and exchange of the heat between evaporator and condenser, the final purpose for realizing refrigeration.
Compression process in actual vapor compressed refrigerating circulating system is to provide power for system circulation, and system is done
Work(, increase the interior energy of system.It is primarily present two aspects by the way of plant equipment (compressor) is come to system increase interior energy
Loss：On the one hand it is loss caused by oneself factor：1, do saturation refrigerant vapour within the compressor, gas interior and gas with
Friction between cylinder wall, and gas and outside heat exchange；2, loss of the cold-producing medium stream through compressor inlet and outlet valve；Separately
On the one hand it is loss caused by energy conversion:Compressor first converts electric energy to mechanical energy, then converts mechanical energy into heat energy, and two
Greater loss be present in secondary conversion.In addition, there is feeder ear loss in actual motor power factor less than 100%.So for system
SAPMAC method system acting increase system interior energy and use mechanical compress mode, compressor can be made to do substantial amounts of idle work, caused
Cooling cycle system energy consumption is too high.
