One of the air-conditioner outdoor unit illustrating referring to figs. 1 through Fig. 5 is characterised in that to have cooling device 2, and furtherly, one of the cooling device 2 of Fig. 1 to Fig. 2 is characterised in that for supply with the feed path of cooling waters (7) to water conservation portion 42.Therefore, then, with reference to Fig. 6 and Fig. 7, the feed path of the cooling water of cooling device 2 (7) is described.
First, in forming the cooling device 2 of air-conditioner outdoor unit, in the situation that have cooling water 7 as water storage in the hopper 3 of the starting point of feed path, cooling water 7 is expelled to permeable 5 (with reference to Fig. 7) from first row water hole 36 by gravity etc.The cooling water 7 of this discharge is by so-called capillarity the inside that is penetrated into radially permeable 5 centered by first row water hole 36.A part that is penetrated into the cooling water 7 in permeable 5 is further supplied with to water conservation portion 42 by the contact portion between permeable 5 and water conservation portion 42.
By above-mentioned structure, 36 cooling waters 7 of discharging from first row water hole, be penetrated into the inside of permeable 5 on a large scale after, by the contact portion between permeable 5 and water conservation portion 42, to water conservation portion 42, supply with, therefore can with the offering position and offer quantity independently, water conservation portion 42 is supplied with to cooling water 7 on a large scale and equably of first row water hole 36.
On the other hand, hopper 3 has second row water hole 37, and cooling water 7 is also discharged from second row water hole 37 towards permeable 5.The cooling water 7 dropping to from second row water hole 37 permeable 5 is also supplied with towards water conservation portion 42 with the contact portion of water conservation portion 42 by permeable 5 by the inside of permeable 5.
Second row water hole 37 has following function: in the situation that the evaporation capacity of the situation of heat etc., cooling water 7 more than the displacement from first row water hole 37 permeable 5 cooling water 7 that cannot keep q.s, to permeable 5, supplement cooling water 7.Furtherly, as shown in Figure 6, during from top view, second row water hole 37 is arranged on the extended line of indulging grid portion 44.By this structure, from second row water hole 37, drop to the cooling water 7 permeable 5, in permeable 5, with beeline, arrive the water conservation portion 42 that indulges grid portion 44, and flow swimmingly on short transverse H along this water conservation portion 42.Along the mobile cooling waters 7 of this vertical grid portion 44, in vertical grid portion 44, flow to the water conservation portion 42 that is formed at lined sub-portion 45 with the intersection point of lined sub-portion 45, therefore, even if hold the situation of evaporable heat at cooling water 7 inferior, also can supply with efficiently cooling water 7 to the integral body of water conservation portion 42.
From the above point of view, preferably second row water hole 37 has and can regulate according to meteorological condition the controller for opening and closing (not shown) of the discharge rate of cooling water 7.According to this structure, can the in the situation that of heat, open above-mentioned controller for opening and closing and discharge cooling water 7, to permeable 5 and water conservation portion 42, supply with the cooling water 7 of q.s, and the discharge rate of stating controller for opening and closing and limiting cooling water 7 is closed in the situation ShiShimonoseki at rainy day, cloudy day, avoids the waste of cooling water 7.
By supplying with cooling water 7 with reference to the feed path of Fig. 6 and Fig. 7 explanation towards water conservation portion 42, cooling water 7 vaporizations in water conservation portion 42, thus as shown in Figure 8, the extraneous air a1 that is drawn into air inlet 12 is cooled (latent heat of vaporization of cooling water 7), and cooled air amount a2 supplies with towards heat exchanger 11 by air inlet 12.As a result, the heat exchanger effectiveness carrying out can be improved between air amount a2 and heat exchanger 11, and the electric power consumption of the off-premises station main body 1 that is accompanied by its running can be reduced.
Yet, although be illustrated, but in the situation that will realize the economize on electricity of general family, especially, on the daytime in the summer of improving by leaps and bounds because of refrigeration electric power consumption, the electric power consumption of air-conditioning accounts for whole electric power consumptions only about half of of the family that is in, and therefore in order to realize efficiently the economize on electricity of general family, first must realize the economize on electricity of air-conditioning.About the power-saving technique relevant to this air-conditioning, in the past, at the spray nozzle by from being built in off-premises station main body, cooling water is sprayed direct cooling heat exchanger, for example improve thus, in the cooling device (No. 4077558 communique of Japan Patent) of the heat exchanger effectiveness of heat exchanger, except spray nozzle, the discharge pipe line of the cooling water after supply channel that also need to be from hopper to spray nozzle, water spray and then the complicated water spraying mechanisms such as device that need to control the water spray action of spray nozzle, therefore correspondingly cause cost to improve.
And above-mentioned spray nozzle should be installed on the inside in off-premises station main body in advance in design phase and fabrication stage, therefore cannot the off-premises station main body of using at present be carried out rear installation and be used.In other words, in order to import this cooling device, need to change the off-premises station using at present, and again buy the off-premises station that possesses injection nozzle, therefore correspondingly cause cost to improve, exist the economize on electricity countermeasure as general family to lack effective problem.
In addition, by the water conservation cloth that makes to contain cooling water, contact the cooling device (for example TOHKEMY 2010-216709 communique) of direct cooling heat exchanger with heat exchanger, make air inlet suck water conservation cloth and it is contacted with heat exchanger, therefore producing water conservation cloth and stop up air inlet and the extraneous air of requirement cannot be blown to this problem of heat exchanger.In addition, be difficult to make water conservation cloth and heat exchanger surface uniform contact, it is unstable that cooling effect becomes.Thereby existence cannot obtain this problem of stable power savings.
And then, in off-premises station main body, near configuration gasket material heat exchanger, cooling water is for example run down into, in the cooling device (TOHKEMY 2004-003806 communique) of the next cooling air amount of above-mentioned gasket material, except gasket material, also need to supply with the complicated cooling water feed mechanism such as the device of cooling water, the device that above-mentioned supply is controlled towards above-mentioned gasket material, therefore correspondingly cause cost to improve.And above-mentioned feed mechanism should be installed on the inside of off-premises station main body in advance in design phase and fabrication stage, so produces the unfavorable condition that cost is high, exists the economize on electricity countermeasure as general family to lack effective problem.
On the other hand, according to the cooling device 2 referring to figs. 1 through Fig. 8 explanation and the air-conditioner outdoor unit that uses it, can solve above-mentioned whole issue.For example, the cooling end 4 of the cooling device 2 of pie graph 1 to Fig. 8 is, spongiform water conservation portion 42 is installed on to matrix part 41.In other words, water conservation portion 42 is supported by matrix part 41.By this structure, from the viewpoint of cooling effectiveness, the shape of water conservation portion 42, size can be set as to best formation.And spongiform water conservation portion 42 is installed on matrix part 41, so processing during construction operation becomes easily, can reduce construction cost.
