Other embodiment of < >
Embodiments of the present invention have more than been described, but the present invention is not limited to these embodiments, can carries out various changes, improvement etc. in the scope that does not depart from its purport.
In described each embodiment, as shown in Figure 2, enumerate each spray nozzle 21 with three side plate 12a, 12b in opposite directions of heat exchanger 13,12c on, with downwards taking the posture of vaporific ejection water droplet and the mode in equal height position in the horizontal direction spaced interval and situation about being configured be illustrated as example, but be not limited thereto.Due to the cooling effect approximate equality of sprayer unit 20 feed through to the roughly gamut of heat exchanger 13, therefore, for example, also off-premises station 11A that can be is as shown in Figure 7 such, towards heat exchanger 13 with vaporific ejection water droplet (in other words each spray nozzle 21 is arranged to, along the extraneous air towards heat exchanger 13 flow, with vaporific ejection water droplet) posture.Lift concrete example as described below.
Each spray nozzle 21 is to allow water droplet be configured with the posture of vaporific ejection towards heat exchanger 13., each spray nozzle 21 is configured to make it axially towards the direction of the flow direction along air (air-flow).Move towards heat exchanger 13 along the direction of described air-flow on one side with radial diffusion on one side with the water droplet of vaporific ejection from each spray nozzle 21.Whole or its most of gasification before arriving heat exchanger 13 of water droplet.
In the case of each spray nozzle 21 as described above with towards level or slightly tilt direction be arranged on off-premises station 11A with the posture of vaporific ejection water droplet, as shown in Figure 8, multiple spray nozzles 21 preferably with three side plate 12a, 12b in opposite directions of heat exchanger 13,12c on spaced interval be configured.More specifically, based on the scope with the water droplet diffusion of vaporific ejection from each spray nozzle 21, towards the air of heat exchanger 13 by the cooling scope of each spray nozzle 21, multiple spray nozzles 21 for example separate the interval of tens of centimetres of left and right and scatter configuration at above-below direction and horizontal direction each other.In this configuration example, the scope spreading from each spray nozzle 21 exemplified with water droplet is for example diameter 50cm left and right, and the width of side plate 12a is for example 100cm left and right, and the width of side plate 12b, 12c is 30cm left and right, and the height of each side plate is the situation of 80cm left and right.And, side plate 12a along the vertical direction and horizontal direction be arranged with 4 spray nozzles 21, be arranged with respectively along the vertical direction 2 spray nozzles 21 at side plate 12b and side plate 12c.
Each spray nozzle 21 is set as described above, and the cooling effect approximate equality ground of sprayer unit 20 feeds through to the roughly gamut of heat exchanger 13.
In addition, at spray nozzle 21 with heat exchanger 13(, along flowing of the extraneous air towards heat exchanger 13) in situation about being configured with the posture of vaporific ejection water droplet, multiple spray nozzles 21 for example also can arrange unevenly, to obtain the cooling effect higher than other region in a part of region of heat exchanger 13.Lift concrete example as described below.
Fig. 9 configures routine skeleton diagram for illustrating with respect to other of the spray nozzle 21 of heat exchanger 13.In Fig. 9, omit the diagram of spray nozzle 21.Heat exchanger 13 shown in Fig. 9 has three heat-transfer pipe P1, P2, P3.Three heat-transfer pipe P1, P2, P3 possess refrigerant path independent of each other.Each heat-transfer pipe has turns back at the both ends of the width of heat exchanger 13 and tortuous refrigerant path.Be provided with the entrance of cold-producing medium in one end of each heat-transfer pipe (being right-hand member) in Fig. 9, be provided with the outlet of cold-producing medium at the other end (being left end) in Fig. 9.
There is the supercooling liquid of the supercooling degree of appointment for cold-producing medium being become in heat exchanger 13, preferably have near supercooling region (end of downstream side region) SB1, SB2, the SB3 of refrigerant outlet of emphasis ground Cooling Heat Transfer pipe P1, P2, P3.In the configuration example shown in Fig. 9, multiple spray nozzles 21 have emphasis and be arranged on heat exchanger 13 in supercooling region SB1, SB2, SB3 position in opposite directions.
As the concrete example that spray nozzle 21 is had to emphasis is arranged on a part of region, can enumerate following mode.For example, can enumerate 21 of multiple spray nozzles be arranged on heat exchanger 13 in supercooling region SB1, the mode of SB2, SB3 position in opposite directions, or than with position in opposite directions, other region, with supercooling region SB1, SB2, SB3 position in opposite directions on mode of spray nozzle 21 etc. is set thick and fast.
In addition, for example, each spray nozzle 21 also can be configured to as illustrated in fig. 10 the posture with vaporific ejection water droplet upward.
In the case, each spray nozzle 21 is arranged on the position that is positioned at outside and is positioned at downside compared with heat exchanger 13 in off-premises station 11B.Now, in each spray nozzle 21, water guide portion 40 is the water of direct packets bubbles upward, the water that what spraying portion 51 was guided by water guide portion 40 with vaporific ejection towards top comprise a large amount of bubbles.These multiple spray nozzles 21 with heat exchanger 13 three side plate 12a, 12b, 12c in opposite directions, with upward with the posture of vaporific ejection water droplet and with the spaced-apart interval and being configured in the horizontal direction of the mode in equal height (being positioned at the position of downside compared with heat exchanger 13).
Thus, water by water guide portion 40 towards top direct packets bubbles, and by spraying portion 51 by this water that comprises bubble upward with vaporific ejection, also can suppress air in the flowing of the water that comprises bubble in water guide portion 40 and the bias current of water, the water droplet being stably fully micronized with vaporific ejection from spraying portion 51.
And, for have the faster wind speed profile of its flow velocity of the more top side wind speed profile of the position relationship between heat exchanger 13 and pressure fan 14 (result from), flowing towards the extraneous air of heat exchanger 13, spray nozzle 21 from downside upward with vaporific ejection water droplet, therefore, can guarantee respectively to gasify the required sufficient hang time before the water droplet at each position of the short transverse of heat exchanger 13 arrives the position of this heat exchanger 13.Specifically, as described below.
At off-premises station 11B(with reference to Figure 10) in, heat exchanger 13 is erect and is arranged at installation surface (horizontal plane), and, pressure fan 14 is being configured in the position that is positioned at horizontal direction inner side and is positioned at upside compared with heat exchanger 13 in housing 2, towards the air of heat exchanger 13 flow and inhomogeneous, as shown in Figure 11, form the faster wind speed profile of upside flow velocity.This be because, suction inlet place, abridged in the figure that is arranged at side plate 12a, the 12b of housing 2,12c,, near the position (upside) of pressure fan 14, the air velocity being inhaled into is faster.In addition, in Figure 11, represent towards the flowing of the extraneous air of heat exchanger 13 towards the arrow of the horizontal direction of heat exchanger 13, based on pressure fan 14 by off-premises station 11B(housing 2) inner air discharges (with reference to arrow upward in Figure 11) and the flowing of the extraneous air (air) that forms to outside.Represent that the length of the each arrow flowing of this air represents the size of the wind speed on its height and position.
Under this state, when spray nozzle 21 is from the downside of heat exchanger 13 during upward with the structure of vaporific ejection water droplet, become large from spray nozzle 21 to the distance till heat exchanger 13 tops of the downside that is configured in heat exchanger 13.The required hang time of gasification of therefore, being guaranteed fully this drop from spray nozzle 21 with vaporific ejection and towards the water droplet (with reference to the arrow α of Figure 11) on heat exchanger 13 tops.Therefore,, although fast towards flowing of the extraneous air on heat exchanger 13 tops, can before arriving heat exchanger 13 tops, be vaporized.On the other hand, although from the spray nozzle 21 of downside that is configured in heat exchanger 13 to the near distance till heat exchanger 13 bottoms, but because flowing of the air towards this position is slow, therefore, can guarantee fully to gasify the required hang time with vaporific ejection and towards the water droplet (with reference to the arrow β of Figure 11) of heat exchanger 13 bottoms from spray nozzle 21.Accordingly, can before arriving heat exchanger 13 bottoms, make water droplet gasification.Thus, in off-premises station 11B, the position relationship resulting between heat exchanger 13 and pressure fan 14 is forming the faster wind speed profile of flow velocity of upside in the flowing of the air of heat exchanger 13.And, from the bottom of heat exchanger 13 upward the structure with vaporific ejection water droplet, towards the water droplet at the position of the heat exchanger 13 of the large height and position of wind speed, distance till this position from spray nozzle 21 to heat exchanger 13 is larger, towards the water droplet at the position of the heat exchanger 13 of the little height and position of wind speed, distance till this position from spray nozzle 21 to heat exchanger 13 is less, therefore, guarantees fully that respectively each water droplet gasifies the required hang time.Accordingly, the each water droplet gasification respectively before arriving heat exchanger 13 from spray nozzle 21 with vaporific ejection, its result, prevents that heat exchanger 13 is by the situation of getting wet with the water droplet of vaporific ejection from spray nozzle 21.
In each embodiment, in spray nozzle 21, water guide portion 40 entirety are vertically to guide the shape of water, but are not limited thereto shape.The position that, is at least equivalent to guidance field A3 in water guide portion 40 is for by the vertically structure of (being below in the respective embodiments described above) guiding of water.For example, in the water guide portion 40 of each embodiment, at least than bubble forming portion 43 more the position of downstream be the structure that (more specifically, at least than the more position of the water guiding tube 41 of downstream of air introducing port 43a in downstream) vertically guides the water that comprises bubble towards spraying portion 51.According to this structure, air and the bias current of water in the flowing of the water that comprises bubble in water guide portion 40 are inhibited, the effect of the water droplet that acquisition is stably fully micronized with vaporific ejection from spraying portion 51.
In each embodiment, as shown in Figure 1, by the water (to water energising) that electric current is flow through supply from water organization of supply 60, thereby make from sprayer unit 20 chargedly with the water of vaporific ejection, but be not limited to which.For example, as shown in Figure 12 (A), Figure 12 (B), can utilize electrostatic induction to make with the water of vaporific ejection charged, also can as shown in figure 13, make with the water of vaporific ejection charged by airborne electric discharge.Particularly as described below.
