Description
Technical field
This novel jet heat pump cycle that relates to, is specifically related to a kind of heat-driven steam jet heat pump cycle structure.
Background technology
Heat pump (English: Heat Pump) heat pump is a kind of device of the energy drives of utilizing certain form, makes heat transfer to the heat energy Handling device other occasion or medium from certain occasion or medium.Conventionally utilize this technology to realize the low temperature heat energy that is not easy to be utilized, transfer in high temperature heat source and recycle.Heat pump has a variety of according to its know-why differentiation, common are compression heat pump, absorption heat pump, thermoelectric heat pump, heat pipe hot pump etc.Heat pump work all needs to have drive energy conventionally.Divide according to driving-energy source, have thermal source driving, machine power driving, electric energy to drive several large classes.
Compression heat pump is to utilize mechanical energy (as motor, internal combustion engine etc.) to drive compressor, forced working medium refrigerant (as freon, ammonia, carbon dioxide etc.) carries out gas, liquid phase-change, flow with multi-form by medium, utilize phase transition process heat absorption, heat release to realize heat and shift with media flow, realize the heat of low-temperature heat source " contrary " is transferred in high temperature heat source, realize recycling, the kinetic energy of driving is also converted into heat and arrives in the lump output;
Absorption heat pump is to utilize high temperature heat to drive evaporation, the cyclic process of condensing, utilize different conditions liquid, gas to shift, utilize the boiling point difference of medium under different pressures, realize evaporation under condense under higher temperature release heat, lower temperature and absorb heat, realize the heat of low-temperature heat source " contrary " is transferred in high temperature heat source, realize recycling, the heat energy of driving is delivered to output too;
Thermoelectric heat pump is to utilize a kind of PN junction with specific current, hot-fluid function, realize according to current drives, the transfer of heat that realizes PN junction one side to an other side special ability, with electric current as driven by energy, realize the heat of low-temperature heat source " contrary " is transferred in high temperature heat source, realize recycling, drive electric energy to be also converted into heat energy simultaneously and arrive destination simultaneously;
Heat pipe hot pump is to utilize media (refrigerant) the evaporation process heat absorption vaporization of working under vacuum environment, meets condensation knot at the other end, is back to evaporation ends and realizes circulation, simultaneously from high temperature to Conduction At Low Temperature amount of heat by gravity or capillarity.Although the still high temperature that this heat pipe hot pump is realized is to cryogenic heat transfer, and natural heat transfer difference is to have even hundreds of times of above heat transfer efficiencies of decades of times;
Except thermoelectric heat pump, the working mechanism of other nearly all heat pump is all same or similar in some sense, i.e. the carrying by working media (refrigerant), flow, in fact realize its transfer with heat energy and absorption, release.They all will be adopted and force by some way the media implementation heat absorption of vaporizing under lower temperature environments, have arrived under higher temperature environment and have been forced to condensation heat, realize heat and shift with the transfer of medium.
According to the second law of thermodynamics, heat can be realized nature conduction from high temperature heat source to low-temperature heat source, and that heat pipe hot pump can be realized in the situation that not needing driven by energy is high efficiency, heat conducts naturally fast.Other heat pump is all to wish by by the thermal source in low-temperature heat source, and " reverse " is transported in high temperature heat source, realizes the recycling of heat energy, " amplification " of energy utilizes object.
Effectiveness formula according to contrary Carnot cycle: COP=T2/dT.Wherein T2 is the target temperature of heat pump heat output, and dT is the temperature difference between thermal source and target temperature.From formula, can find out, because thermal source can not be absolute zero (0K), therefore efficiency COP theoretical value must be to be greater than 100%.And the temperature difference is less, Energy Efficiency Ratio is higher; Target temperature is higher, the same temperature difference, and Energy Efficiency Ratio is higher.Obviously, heat pump is the very important means of energy-saving and emission-reduction, if apply proper, can allow every profession and trade with can situation huge variation occurring, make huge contribution for solving mankind's energy crisis! Adopt at present the export target temperature of compression, absorption heat pump can exceed 100 DEG C, can be applied in numerous highly energy-consuming industries completely, as food, medicine, papermaking, tire, chemical industry etc. field, the vast scale of realizing highly energy-consuming link is energy-conservation!
After entering 20 century 70s, certain achievement all, in the further relevant jet drainage of research, vacuum theory, by the research to some details, as the research practice of nozzle configuration, mode, pulsation etc. factor, has been obtained in countries in the world.Such as with the closely-related fan without blades of human lives, and the gas amplifier of industrial applications.
Gas amplifier principle is when spraying after the narrow annular channel of gases at high pressure by 0.05～0.1 millimeter of gas amplifier, reach effect principle and the special geometry of gas amplifier by Koln, the low-pressure gas of maximum 10 ~ 100 times can be inhaled into, and blows out from gas amplifier outlet together with original gases at high pressure.Gas amplifier (air amplifier) application was expanded rapidly over the past two years, and conventional vast scale is saved compressed air, and utilized compressed air to realize the commercial Application such as drifting dust, dust suction, material transport, and technology maturation is stable.The medium being more typically inhaled under this application mode is air or steam.If inlet gas is low temperature, low-pressure steam (compressible fluid), driving air-flow is high temperature, high pressure superheated steam, in the time that high-temperature steam sprays from annular jet, meeting expansion, cooling, step-down, mix with low temperature, low-pressure steam simultaneously, reach heat, momentum balance, final air-flow is middle temperature, middle pressure mixed vapour, discharges from outlet.
