(structure of radiator cooler and action)
Be installed in the radiator cooler 50 on the above-mentioned off-premises station 10, mainly constitute by main body 51, water supply piping 52 and nozzle 53.In main body 51, contain auxiliary cooling control module 55 shown in Figure 4.And never illustrated water pipe is supplied with the water of authorized pressure to the upstream extremity of the water supply piping 52 that is positioned at main body 51.And, supply with water supply piping 52 by the feed water valve of being controlled by auxiliary cooling control module 55 54 (with reference to Fig. 4) from the water of this water pipe.
Auxiliary cooling control module 55 is connected with above-mentioned outdoor control unit 19, the auxiliary instruction unpack feed water valve 54 that cools off control module 55 bases from outdoor control unit 19, and from nozzle 53 heat exchanger 32 water sprays.Therefore, when not having the instruction of outdoor control unit 19, can be from nozzle 53 water sprays.Herein, only when high-pressure rose to abnormal level, outdoor control unit 19 shut down to avoid air-conditioning to auxiliary cooling control module 55 output orders.
When outdoor control unit 19 was sent instruction, auxiliary cooling control module 55 opened and closed feed water valve 54 repeatedly, and nozzle 53 heat exchanger 32 are sprayed water off and on.Degree was adjusted to water was dripped to the bottom from the top 32a1 of the medial surface 32a of heat exchanger 32 reliably at intermittence this.That is, spray to the water yield of heat exchanger 32, adjust by auxiliary cooling control module 55 from nozzle 53.
And auxiliary cooling control module 55 also carries out inching according to external air temperature to the degree at intermittence of spraying water from nozzle 53 heat exchanger 32.The data of external air temperature are obtained from extraneous air thermistor 63 by outdoor control unit 19.As water spray intermittence degree inching, make the open mode of feed water valve 54 often be in closed condition, so that increase the water yield along with the rising of external air temperature.Specifically, according to the external air temperature and the correlation table of degree intermittently, auxiliary cooling control module 55 spray water intermittence degree inching.
Water yield control by this auxiliary cooling control module 55, spray to the water of top 32a1 of the medial surface 32a of heat exchanger 32 from nozzle 53, flow to the bottom of heat exchanger 32 reliably, and when flowing to the lower end of heat exchanger 32, roughly evaporate by the heat that comes automatic heat-exchanger 32.
(feature of radiator cooler)
(1) in radiator cooler 50, for the consumption of conserve water, spray water off and on from nozzle 53 heat exchanger 32, so compare, be easy to generate incrustation scale at the medial surface 32a of heat exchanger 32 with the situation of continuous water spray.Therefore, in order to improve outward appearance and to save the space, when the structure that adopts from inboard heat exchanger 32 water sprays of off-premises station 10, spray water if carry out in the past like that being the mode of concentric circles diffusion from nozzle, then must spended time and the time could clean the medial surface 32a of the heat exchanger 32 that is difficult to clean operation.
Certainly, in order to suppress to produce incrustation scale, also can consider to continue the countermeasure of water spray incessantly, but have the problem of water rate costliness from nozzle 53 heat exchanger 32.Therefore, when implementing to be the water spray of concentric circles diffusion as in the past,, must increase the number of times of the operation of the spended time and the clean heat exchanger 32 medial surface 32a in time in order to save water rate.
(2) still, in radiator cooler 50, carry out the water spray that spreads at left and right directions from the top 32a1 of nozzle 53 heat exchanger 32 medial surface 32a.Thus, top 32a1 from the water of nozzle 53 ejection from heat exchanger 32 medial surface 32a flows to the bottom, and can utilize roughly whole of medial surface 32a of water-wet heat exchanger 32, reduce the zone of being sprayed or not sprayed water among the medial surface 32a of heat exchanger 32.One of reason that diminishes as this zone can be listed below, by the top 32a1 from nozzle 53 heat exchanger 32 medial surface 32a carry out about the water spray of diffusion, stable along the path of 32 water downwards of heat exchanger.
That is, as in the past, carry out when central authorities are the water spray of concentric circles from the medial surface 32a of the inboard heat exchanger 32 of off-premises station 10, in this concentrically ringed end, the zone of being sprayed or not sprayed water becomes greatly in the form of a ring, and still, radiator cooler 50 less produces this zone.
Therefore, although in order to improve outward appearance and to save the space, and in radiator cooler 50, adopted from the structure of inboard heat exchanger 32 water sprays of off-premises station 10, but the incrustation scale generating capacity that is difficult to clean the heat exchanger 32 medial surface 32a of operation reduces, and can suppress because of cleaning incrustation scale spended time and the situation in time takes place or take place because of the situation that exists incrustation scale to reduce the heat exchanger effectiveness of heat exchanger 32.
(3) and, in radiator cooler 50, utilize auxiliary cooling control module 55 to carry out water yield adjustment, so that water flows to the bottom reliably from the top 32a1 of heat exchanger 32 medial surface 32a, so can utilize roughly whole of medial surface 32a of water-wet heat exchanger 32, and carry out the abundant cooling of heat exchanger 32.
In addition, when flowing to the bottom reliably,, also produce the generation that suppresses incrustation scale and make the incrustation scale that is produced fall the effect of some by these current on top from the water of nozzle 53 ejection from heat exchanger 32.Utilize this effect, also can reduce the amount of scale of heat exchanger 32 medial surface 32a.
(4) and, in radiator cooler 50, carry out following control, promptly, externally air themperature is higher, under the evaporable situation of the water capacity of heat of wetting interchanger 32 medial surface 32a, reduce intermittently degree (the not ratio of the relative water spraying time of water spraying time), and increase Total Water; Externally air themperature is lower, under the not evaporable situation of the water of heat of wetting interchanger 32 medial surface 32a, prolongs intermittently degree, and reduces Total Water.By this control, can suppress the generation of incrustation scale.
(variation)
(A) in the above-described embodiment, in off-premises station 10, only rise to abnormal level at high-pressure, and from outdoor control unit 19 when auxiliary cooling control module 55 output orders, just from nozzle 53 heat exchanger 32 water sprays.Thus, suppress the waste of water, and save water rate.
To this, improve under heat exchanger effectiveness, the situation cooling off with the electricity charge of saving conditioner by heat exchanger 32 water spray, even make water in large quantities, radiator cooler 50 move for a long time, realize economizing on electricity.For example,, move for a long time, can suppress power consumption by initiatively making radiator cooler 50 in electricity usage amount big time band or peak period.
(B) in the above-described embodiment, illustrated radiator cooler 50 as the situation that is installed in the optional feature on the off-premises station 10, but this radiator cooler 50 also can be from just being installed on the off-premises station 10 at first.During this situation, the main body 51 of the radiator cooler 50 of housing 12 outsides that are disposed at off-premises station 10 in Fig. 2 and Fig. 3 is configured in the inner space of housing 12, can be more prone to improve the outward appearance of off-premises station.And, also assist the wiring of cooling off control module 55 and outdoor control unit 19 easily.
(C) as shown in Figure 5, when the present invention is applicable to the off-premises station 110 with heat exchanger 132, employing is from the extend out radiator cooler of two water supply piping 152a, 152b of main body 151, the left and right directions length of above-mentioned heat exchanger 132 is greater than the length of the left and right directions of the heat exchanger 32 of above-mentioned embodiment, from being located at nozzle 153a, the 153b left and right sides each several part water spray of the medial surface 132a of heat exchanger 132 respectively on these two water supply piping 152a, the 152b front end.At this moment, carry out water spray from the top of the medial surface 132a of nozzle 153a, 153b heat exchanger 132, produce the feature identical thus with above-mentioned embodiment in the left and right directions diffusion.
The radiator cooler that the present invention relates to adopts the structure of heat exchanger water spray from off-premises station, and can suppress the amount of incrustation scale, so be very useful as the device that utilizes the outer heat exchanger of the auxiliary cooling chamber of water.
