Description

Mechanical type spraying heat absorption cooling device

Technical field

The utility model relates to a kind of mechanical type spraying heat absorption cooling device, belong to refrigeration technology field.

Background technology

The refrigerating method of existing air-conditioner adopts freon refrigerant, and its boiling point is gaseous state at subzero tens degree Celsius under the room temperature normal pressure, in order to reach the effect 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, claims exothermic process.Then liquid → gas is heat absorption: gas → liquid is heat release.Belong to the steam compression type refrigeration method, adopt Carnot cycle, Energy Efficiency Ratio improves restricted, and power consumption is big, and the cost height has pollution, service life to lack to environment, and heavy build-in services are after sale still arranged.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of mechanical type spraying heat absorption refrigerating method, characteristics such as it has, and power consumption is little, pollution-free, compressor-free, non-outdoor unit, cost are low, long service life.Technical solution of the present utility model: its structure is that an end of high pressure liquid pump passes through by control valve S ₂Be connected with receiver, the other end and filter and injector, evaporator are connected, UNICOM, its port of export are connected with the heat exchanger inlets end drawing liquid inlet of circulating pump of bleeding end up and down with evaporator through threeway, the liquid back pipe of heat exchanger and liquid-gas separator and receiver are connected, liquid-gas separator outlet side and single magnetic valve S ₅The gas tube that reaches in the receiver is connected, and a side of heat exchanger is established centrifugal blower; When heating, increase dress ceramic electrical heating tube and relay electromic thermostat in the receiver.

Advantage of the present utility model: (1), cooling cycle system are sealing and circulating, can freeze, heat.About 20 ℃ of its boiling points of cold-producing medium, the mechanical type spraying evaporation, mat boil-off gas absorption refrigeration has thoroughly effected a radical cure the harm that freon pollutes.(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, saves compressor.When (3), freezing, in heat exchange, done technical finesse, increased by 1 times of the speed (1.5m/s) of time liquid return-air, produce " negative effect ", exchange to 0 ℃～5 ℃ from-18 ℃ (constants), the heat that room air discharges is transferred in cold liquid and the atomization and vaporization gas, this a spot of heat of liquefaction, adopt the kinetic energy work done to transfer interior energy method to again, feed and in storage liquid, to inflate the generation boil-off gas in the gas tube, in machine, finish thermal balance automatically, create unique new method of eliminating heat of liquefaction, save off-premises station to outdoor discharges heat, reduce neighbourhood's dispute.(4), abandon Carnot cycle, save compressor, obvious energy conservation, the Energy Efficiency Ratio Ne of green air conditioner can bring up to greater than 10～15; (existing air-conditioning Ne=2.8～3.2) we can say clear ahead status in the world.(5), the mechanical type spraying heat absorption process of refrigerastion is physical change, the matter of cold-producing medium CH-101 is constant forever, because this cold-producing medium is water insoluble, can increase the service life.(6), do not have heavy after sale build-in services, and eliminated the hidden danger that the rotten rust fracture of off-premises station several years after-poppet is fallen down, easy to use.

The specific embodiment

The contrast accompanying drawing, an end of high pressure liquid pump 8 is by ending control valve S ₂Be connected with receiver 1, the other end and filter 9 and injector 4, evaporator 3 are connected, bleed drawing liquid circulating pump 6 entrance point through threeway and evaporator about in the of 3 UNICOM, its port of export be connected with heat exchanger 10 entrance points, the liquid back pipe of heat exchanger 10 and liquid-gas separator 5 and receiver 1 are connected, liquid-gas separator 5 outlet sides and single magnetic valve S ₅The gas tube that reaches in the receiver 1 is connected, and a side of heat exchanger 10 is established centrifugal blower 11; When heating, increase dress ceramic electrical heating tube and relay electromic thermostat in the receiver 1.The course of work: kind of refrigeration cycle: start high pressure liquid pump 8, the refrigerant liquid of receiver 1 is extracted out, through filter 9 high pressure input injector 4, spray and form the vacuum suction phenomenon, pressure in the receiver 1 is descended, evaporating temperature (boiling point is directly proportional with pressure) has correspondingly been fallen at the end, producing the mixed pressure part that a large amount of steams are sucked into injector 4 mixes with the high-voltage high-speed liquid stream of nozzle, impel the refrigerating fluid in the diffusion part to form atomization and vaporization gas, produce the absorption refrigeration effect, finish and evaporate absorption refrigeration technology for the first time, then gas and liquid in the evaporator 3 are extracted out by the drawing liquid circulating pump 6 of bleeding, (7000 rev/mins) produce centrifugal force under the impeller of pump rotates at a high speed, form atomization and vaporization gas for the second time again, more than jet atomization, endothermic effect is bigger, the boil-off gas of atomizing and the cold liquid that part is condensed are imported heat exchanger 10 entrance points together, the centrifugal blower 11 of mat one side sucks indoor hot-air and carries out heat exchange, uniqueness of the present invention is in adopting two technical measures, (1) control heat exchange caloric receptivity (refrigerating capacity that is exchanged), liquid back pipe, gas velocity improves 1 times (1.5m/s), the liquid temp of refrigerating fluid of drawing liquid circulating pump 6 supply of then bleeding is that (this is that the refrigeration characteristic curve of cold-producing medium CH-101 is learnt after circulation in 3～5 minutes for a constant temperature-18 ℃, can reach constant-18 ℃ cold liquid, and the freezing point temperature of this cold-producing medium is more than-170 ℃), with return liquid speedometer control heat exchanger 10 exchange to back the liquid suction temperature from-18 ℃ to 0 ℃～5 ℃, reach " negative effect ", take the refrigerating capacity of deep cooling part away, (2) treatment fluid heat-transmission, transfer in the cold liquid and go because of indoor hot-air discharges heat, become boil-off gas, adopted above-mentioned technical measures return-air to return under liquid temp lower (0 ℃～5 ℃) advantage, use the method that the kinetic energy work done is converted into interior energy, to return and connect liquid-gas separator 5 under the liquid muffler, liquid turns back to receiver 1 gas and separates, by unidirectional electrical magnet valve S ₅Connect gas tube 2, refrigerant liquid in receiver 1 is inflated, increased the kinetic energy of molecule, from initial velocity to end speed (Vo → Vt), produce boil-off gas again, latent heat-transmission around boil-off gas will be drawn, produce refrigeration, can disappear in heat in the return-air, kinetic energy work done become, the evaporation of being inflated generation low in calories of returning in the liquid has absorbed, so profoundness of the present invention is heat of liquefaction autobalance in receiver 1 of the phase transition process generation of gas → liquid has been solved, both do not wanted the liquifying method of compressor, off-premises station does not enter heat of liquefaction again, abandons Carnot cycle, start new green refrigeration circulation, sealing and circulating reaches 15 minutes, can make room temperature drop to 15 ℃～25 ℃ from 28 ℃～36 ℃, and the people is felt comfortably cool.

Heat circulation: the employing electrical heating method increases ceramic heat pipe, the manufacturing steam (60 ℃～80 ℃) of adorning 1 1kw and controls temperature with relay electronic thermostatic controller in receiver 1, heats with the vapours exchange to get final product.
