Description
The utility model relates to a kind of green refrigeration EGR-mechanical type sweat cooling EGR, belong to refrigeration technology field.
Existing air-conditioner adopts freon refrigerant, and its boiling point is at subzero tens degree Celsius, under the room temperature normal pressure, be gaseous state, in order to reach the technology of liquid evaporation absorption refrigeration, must adopt compressor earlier the cold-producing medium of gaseous state to be compressed into liquid state, liquefaction process will produce heat of liquefaction, and this is an exothermic process.Then liquid → gas is heat absorption: gas → liquid is heat release.So modern air conditioning device refrigeration is the steam compression type refrigeration method, adopts Carnot cycle, the restricted raising of Energy Efficiency Ratio, power consumption is big, pollution is arranged, cost height, service life are short.
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of mechanical type sweat cooling EGR, has little, pollution-free, the characteristics such as cost is low, compressor-free, long service life of power consumption.
Technical solution of the present utility model:
Its structure is the end of an end of high pressure liquid pump by magnetic valve and fluid reservoir, another termination injector of high pressure liquid pump, the other end of fluid reservoir communicates with the flow container that returns of heat exchanger by graduating valve, the mixed pressure chamber of injector joins by magnetic valve and evaporator, one end of the other end of injector and liquid-gas separator joins, the other end of liquid-gas separator is paid jar with evaporation and is joined, the bottom of evaporation pair jar enters the entrance point A of heat exchanger by triple valve, control, side at heat exchanger is established centrifugal blower, dress relay control electrical heating (heating usefulness) in the evaporator
Advantage of the present utility model:
1. cooling cycle system is a sealing and circulating, but also cooling and warming.About its boiling point of cold-producing medium (20 ℃), mechanical injection evaporation, mat boil-off gas, absorption refrigeration.
2. cold-producing medium is the low liquid that boils, and is in a liquid state under the room temperature normal pressure, need not liquefying plant.
3. the heat exchange when freezing adopts " negative effect " to exchange to 0 ℃ from-18 ℃, room air discharges transferring in the cold liquid of heat, does not have heat of liquefaction, has eliminated with regard to balance as long as the cold of cold liquid 〉=air discharges heat, return 0 ℃ of liquid temp, can save condenser and ventilating fan to outdoor discharging hot gas.
4. fluid exchange heat, cold liquid transmission power power consumption is little, and the heat-transmission refrigeration of diving is got in the evaporation of cold-producing medium mat liquid, only with liquid temperature decline constant temperature at-18 ℃, return liquid temp at 0 ℃, can abandon the circulation of Kano system, save compressor, Energy Efficiency Ratio significantly improves at this point, and Ne can be greater than 15～20.
5. the mechanical type evaporation process is a physical change process, and the matter of cold-producing medium is constant forever, and cold-producing medium is water insoluble again increases the service life.
Accompanying drawing is a structural representation of the present utility model
Among the figure 1 is electronic thermometer, the 2nd, Pressure gauge, the 3rd, and heat exchanger, the 4th, centrifugal blower, the 5th, graduating valve, the 6th, fluid reservoir, the 7th, high pressure liquid pump, the 8th, injector, the 9th, liquid-gas separator, the 10th, jar, the 11st is paid in evaporation, magnetic valve, the 12nd, evaporator, the 13rd, relay, the 14th, inflation box, the 15th, check valve, the 16th, supercharging infusion pump, the 17th, triple valve, the 18th, control valve.
Further describe the technical solution of the present utility model and the course of work below in conjunction with accompanying drawing:
Kind of refrigeration cycle; starting high pressure liquid pump 7 extracts the cold-producing medium of receiver 6 out; high pressure input injector 8; jet pipe sprays and forms vacuum; evaporator 12 internal pressures are reduced; the corresponding evaporating temperature (boiling point is directly proportional with pressure) that reduced; produce in the diffusion part that a large amount of boil-off gas are sucked into injector 8 and make mist; inject liquid-gas separator 9 at a high speed; liquid particle pools in the liquid input evaporation pair jar 10 in vaporific; low-pressure low-temperature liquid flows into threeway and the boil-off gas separated is mixed into one in pressure regulator valve 18 enters inflation box in the evaporator 12, carries out inflation and evaporates the actual kinetic energy that increases the refrigerant liquid molecule, from v
0→ v
tIncrease evaporation capacity, latent heat-transmission around boil-off gas will be drawn, produce refrigeration, 12 cold-producing medium is irritated in evaporation cool to cold liquid about 18 degrees below zero Celsius, with supercharging liquid pump 16, the indoor hot-air of squeezing into the suction of heat exchanger 3 and centrifugal fan exchanges, control back flow velocity (1.5m/s) by graduating valve 5, heat exchange ℃ rises to 0 ℃ to cold liquid-18, returns in the receiver 6, finish once in circulation, liquid temperature constant temperature is at-18 ℃ in the continuous three minutes evaporators 12, liquid temperature-18 in the heat exchanger 3 ℃, receiver 6 return 0 ℃ of liquid temp, minimum 5 ℃ of the cold wind temperature of exhaust outlet, can make indoor temperature in 15 minutes, drop to 15 ℃～32 ℃, reach the air conditioner refrigerating purpose.Phase-transition liquid → gas → the liquid of refrigeration is carried out heat exchange with cold liquid, reduces power consumption, and what return receiver 6 is the cold liquid of zero degree, therefore saves the process of compressing and liquefying, and has eliminated heat of liquefaction again.So the thermal balance of this refrigeration only betides on the heat exchanger cold of cold liquid 〉=air release heat.Control back flow velocity (1.5m/s) by graduating valve and return liquid temp constant temperature at 0 ℃, so indoor transfer of heat in liquid-18 ℃ rise to 0 ℃, be eliminated with this " negative effect " technical finesse, returned 0 ℃ of liquid, just do not needed condenser and ventilating fan to outdoor discharging hot gas.
Heat circulation:
Turn off high-pressure pump 7, two magnetic valves 11 start simultaneously, change passage, connect the power supply of earthenware heater with relay 13, with a heating means, cold-producing medium boiling vaporization with evaporator 12, directly vapours feeding heat exchanger 3 is carried out heat exchange (the nationality centrifugal fan sucks cold air) heat exchanger 3 with indoor cold air and play the condenser effect, after vapours turns cold, steam condenses into liquid, carry out liquid to evaporator 12 and replenish, additional liquid is that hydrothermal solution (condensation point temperature) is so heat much simple.Only vapours is led directly to heat exchanger 3, the cold and hot exchange, vapours is caught a cold and is condensed into liquid, then finishes once circulation, 3～5 fens clock times of circulation of going round and beginning again, 25～36 ℃ of exhaust outlet hot air temperature are used less than 25 fens clock time room temperatures and are risen to 15～28 ℃.(heat index and can add electrical heating (quartz ampoule or earthenware) in addition and calculate through theory if can not reach air-conditioning, heat bigger 1 times than the refrigeration consumes power, but have only 1/3 to can save energy 60～70% than existing air-conditioner power consumption, adopt the air-conditioner of the present invention's refrigeration to compare, can save 800%～900% with the power consumption of existing air-conditioner.Specifically, existing air-conditioner starts 1 hour power consumption and can give and adopt air-conditioner of the present invention with 8～9 hours.
