Detailed description of the invention

Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.

The invention provides a kind of split-type air conditioner, as shown in Figure 1, comprise indoor apparatus of air conditioner 10 and air-conditioner outdoor unit 20; The air inlet 12 of indoor apparatus of air conditioner 10 is positioned at below, air outlet 11 is positioned at top, and in indoor apparatus of air conditioner 10, indoor set blower fan 13 is installed on the position between air inlet 12 and air outlet 11, freezes in the position that evaporimeter 15 is arranged on air outlet 11 place; In air-conditioner outdoor unit, the 20 off-premises station blower fans 22 being provided with compressor, choke valve, condenser 21, produce radiating airflow by off-premises station blower fan 22 and are taken away by the heat that the fin of condenser 21 distributes; Refrigerant loop between indoor apparatus of air conditioner 10 and air-conditioner outdoor unit 20, current supply circuit etc. are connected (in Fig. 1, compressor, choke valve, refrigerant loop, current supply circuit omit not shown) by pipeline; In addition, the part that split-type air conditioner of the present invention is obviously different from prior art is, air inlet 12 place be positioned in indoor apparatus of air conditioner 10 below evaporimeter 15 is also provided with condensed water heat exchanger 16, and the water inlet of condensed water heat exchanger 16 is connected with the condensed water outlet pipe 14 of evaporimeter 15, delivery port is connected with the condensate draining pipe 17 of indoor apparatus of air conditioner; On the other hand, in air-conditioner outdoor unit 20, be positioned at directly over condenser 21 and be disposed with condensing drip water pipe 23 and condensing drip water pond 24 from top to bottom; Condensing drip water pipe 23 is connected with the condensate draining pipe 17 of indoor apparatus of air conditioner, and is provided with weeper bottom condensing drip water pipe 23; Condensing drip water pond 24 is horizontally disposed with along the fin array direction of condenser 21, and the bottom of condensing drip water pond 24 is provided with along the fin array directional spreding of condenser 21 through hole that drips that several pore sizes are 0.5 ~ 1.5mm.

The flow process that this split-type air conditioner realizes condensation water recovery and use is as follows: when this split-type air conditioner freezes, the condensed water of indoor apparatus of air conditioner refrigeration condensation is because Action of Gravity Field is from the condensed water heat exchanger of the condensed water outlet pipe inflow air inlet of evaporimeter, because now condensate temperature is usually at 11 ~ 13 DEG C, the air themperature that air inlet enters is usually at 25 ~ 28 DEG C, therefore the air that condensed water is entered by condensed water heat exchanger and air inlet carries out first time heat exchange, precooling is carried out to the air that air inlet enters, improve the temperature of condensed water simultaneously, reduce the temperature difference of condensed water and outside air, contribute to reducing cryogenic condensation water and flowed to the waste of the cold in the process of air-conditioner outdoor unit by condensate draining pipe, then, condensed water after first time heat exchange flows out from the delivery port of condensed water heat exchanger, due to the difference in height of air-conditioner outdoor unit and air conditioner indoor unit evaporator position, condensed water flows into the condensing drip water pipe in air-conditioner outdoor unit through condensate draining pipe under gravity, and accumulation forms hydraulic pressure in condensing drip water pipe, force condensed water from the condensing drip water pond immediately below the weeper of condensing drip water pipe drops onto, because the fin array direction of condensing drip water pond along condenser is horizontally disposed with, condensing drip is fallen after in condensing drip water pond and is spread out, and makes hydraulic pressure in condensing drip water pond explain aobvious reduction compared to the hydraulic pressure in condensing drip water pipe, air-conditioner outdoor unit intermittent work, when air-conditioner outdoor unit quits work, above and below condensing drip water pond, air pressure is identical, pore size due to the through hole that drips of the bottom of condensing drip water pond is 0.5 ~ 1.5mm, aperture is less, and when air-conditioner outdoor unit quits work, the condensation water quantity that indoor apparatus of air conditioner produces is also less, only has and flows in condensing drip water pond compared with the condensed water of low discharge, therefore at the condensed water spread out because its surface tension effects is difficult to from the through hole drippage that drips bottom condensing drip water pond, when air-conditioner outdoor unit startup work, because off-premises station blower fan produces air-flow, the condenser below condensing drip water pond is dispelled the heat, air pressure below condensing drip water pond is reduced, therefore the through hole that drips impelling condensed water to arrange from condensing drip water pond bottom part cloth with the draught head of below above condensing drip water pond drops onto the fin of condenser, and because of airflow function, condensed water flows and forms moisture film on the fin of condenser, the fin of condenser is lowered the temperature, realize second time heat exchange, the evaporation and the condensed water on the fin of condenser absorbs heat rapidly under the acting in conjunction of high temperature and air-flow, further the fin of condenser is lowered the temperature.

The above-mentioned flow process of condensation water recovery and use is realized by split-type air conditioner of the present invention, can see, the first time heat exchange of condensed water is utilized to carry out precooling to the air that indoor apparatus of air conditioner air inlet enters, the energy consumption of evaporator refrigeration in indoor apparatus of air conditioner can be reduced, and utilize the second time heat exchange of condensed water and the fin of evaporation endothermic to air-conditioner outdoor unit inner condenser to lower the temperature, the radiating efficiency to condenser can be improved, thus the consumption reduced cold-producing medium, improve the COP value (CoefficientofPerformance of split-type air conditioner integral refrigerating system, cycle performance coefficient), and condensed water evaporates rapidly in second time heat transfer process, the liquid condensation water yield that split-type air conditioner finally can be discharged significantly reduces, thus avoid a large amount of liquid condensation water discharge often cause outdoor high-altitude to drip, the inconvenient situation such as road surface slippery situation, solve condensed water and arbitrarily discharge the problem of making troubles to outdoor pedestrian.Especially, split-type air conditioner of the present invention realizes in the overall process of condensation water recovery and use, the flowing transmission of condensed water is all be achieved by airflow function when condensed water Action of Gravity Field and air-conditioner outdoor unit work, not by extra energy consumption power, really effectively reach energy-conservation object.It will be further appreciated that, split-type air conditioner of the present invention, not by water pump, under the prerequisite that other extra power consuming device such as spray thrower is controlled, utilize the condensing drip water pipe and condensing drip water pond that arrange in air-conditioner outdoor unit cleverly, directly achieve the atomizer function with air-conditioner outdoor unit intermittent work synchronised: the condensed water from indoor apparatus of air conditioner first accumulates and forms certain hydraulic pressure in condensing drip water pipe, and also non-immediate opening water outlet bottom condensing drip water pipe, but by arranging weeper water outlet, avoid the too fast outflow of condensed water and the region be ejected into outside condensing drip water pond, ensure that condensed water successfully can be dropped in condensing drip water pond by weeper, and be horizontally disposed with due to the fin array direction of condensing drip water pond along condenser, therefore condensing drip is fallen after in condensing drip water pond and is spread out, hydraulic pressure reduces, quit work at air-conditioner outdoor unit, above and below condensing drip water pond, air pressure is identical, and the pore size of the through hole that drips of the bottom of condensing drip water pond is under the condition of 0.5 ~ 1.5mm, condensed water in condensing drip water pond due to its surface tension effects be difficult to from bottom condensing drip water pond drip through hole drippage, thus storage and the gathering of a period of time can be formed in condensing drip water pond, when air-conditioner outdoor unit startup work, because off-premises station blower fan produces air-flow, the condenser below condensing drip water pond is dispelled the heat again, air pressure below condensing drip water pond is reduced, therefore impel condensed water to drop onto the fin of condenser from the through hole that drips bottom condensing drip water pond above condensing drip water pond with the draught head of below, and it is that fin array directional spreding along condenser is arranged that the through hole that drips bottom condensing drip water pond drips, thus made condensed water can drop onto different fin from different through hole distributions of dripping, form the effect of aerosol dispersion, by second time heat exchange and evaporation endothermic, the different fin to condenser are lowered the temperature, so repeatedly, just achieve and air-conditioner outdoor unit intermittent work synchronised.

In actual applications, in order to ensure that the condensed water heat exchanger arranged in indoor apparatus of air conditioner has good heat transfer effect, can be optimized the structure of condensed water heat exchanger.Fig. 2 shows a kind ofly has the indoor apparatus of air conditioner structural representation of optimizing structure.As shown in Figure 2, this condensed water heat exchanger 16 of optimizing structure is by vertically to place and some condensed water heat exchanger fin 16a of horizontal laid out in parallel and convolution are formed through the condensed water radiator coil tube 16b of described some condensed water heat exchanger fins; Wherein, the water inlet of condensed water heat dissipation plate 16b pipe is connected with the condensed water outlet pipe 14 of evaporimeter 15, and the delivery port of condensed water radiator coil tube 16b is connected with the condensate draining pipe 17 of indoor apparatus of air conditioner; In Fig. 2, other label implication is identical with Fig. 1.Utilize the condensed water heat exchanger fin of this structure, increase and flow through the condensed water of condensed water radiator coil tube and the comes into heat transferring contact area of air, improve heat exchanger effectiveness.

On the other hand, in order to ensure that the condensing drip water pipe that arranges in air-conditioner outdoor unit and condensing drip water pond can reach good atomizer effect, can be optimized the structure of wherein condensing drip water pipe and condensing drip water pond.Fig. 3 shows a kind ofly has the air conditioner outdoor unit structure schematic diagram of optimizing structure.As shown in Figure 3, this has in the air-conditioner outdoor unit 20 of optimizing structure, and inner space is divided into condenser installs chamber and chamber installed by compressor by dividing plate 26, condenser 21 is installed on condenser and installs chamber, and compressor 27 is installed chamber and is installed on compressor installation chamber, the formation refrigerant loop and back flow of refrigerant input channel 28 and cold-producing medium supply output channel 29 are connected with compressor 27, condenser 21, and the special improvements of this programme are, condensing drip water pipe 23 is designed to strip, and be horizontally set at directly over condensing drip water pond 24 along the fin 21a orientation of condenser 21, the weeper of condensing drip water pipe 23 is multiple and is arranged on the bottom of condensing drip water pipe along the length direction distribution of condensing drip water pipe, makes condensed water can drop onto more equably in condensing drip water pond 24 like this, simultaneously, if the weeper of condensing drip water pipe arranges too much or too small, condensing drip can be caused to fall the excessive velocities or excessively slow of condensing drip water pond, and make it asynchronous with air-conditioner outdoor unit intermittent work, therefore the pore size of the weeper of condensing drip water pipe is preferably set to 4 ~ 6mm, and the distance between the fin of condenser bottom condensing drip water pond and immediately below it is preferably 1.5 ~ 2.5cm, make the fin 21a of the distance from bottom condenser of condensing drip water pond 24 nearer, thus when air-conditioner outdoor unit startup work, larger flow velocity is produced in the narrow space of the radiating airflow allowing off-premises station blower fan operate to apply the fin of condenser between condensing drip water pond and condenser fins, form stronger suction function, above condensing drip water pond, then air velocity is less, air pressure is larger, and then form larger draught head with below above condensing drip water pond again, impel condensed water more smooth, drop onto the fin of condenser from the through hole that drips bottom condensing drip water pond fast.

In addition, consider as special circumstances, such as, when air-conditioner outdoor unit converting operation or stoppage in transit etc., the condensed water accumulated in condensing drip water pond may be caused not used rapidly, thus spilling condensing drip water pond drops onto bottom the cabinet of air-conditioner outdoor unit, and then equipment may be caused to get rusty, affect the cabinet life-span, and also result in liquid condensation water and discharge situation out of control.Therefore, can also arrange water dish 25 in air-conditioner outdoor unit 20 of the present invention, this water dish 25 is horizontally placed on immediately below condenser along the fin 21a orientation of condenser 21, as shown in Figure 3.If the condensed water accumulated in condensing drip water pond too much overflows, then can be dropped in water dish, prevent that the condensed water of spilling causes equipment to get rusty, liquid condensation water discharges situation out of control and occurs, moreover, when air-conditioner outdoor unit resumes operation, radiating airflow then can skim at a high speed the condensed water in water dish, and the temperature of radiating airflow is relatively high, make the condensed water heat absorption evaporation in water dish, reduce radiating airflow temperature, utilize the process that the radiating airflow being condensed the cooling of water evaporation endothermic dispels the heat to condenser fins simultaneously, also indirectly improve the cooling heat dissipation efficiency to condenser fins, not only define thus and the third time heat exchange of condensed water is utilized, the liquid condensation water be accumulated in water dish is also made to be evaporated gasification, thus reduce again, even stop the discharge of liquid condensation water, further strengthen energy-conservation, emission reduction effect.
