Description

The indoor set of air conditioner
Technical field
The present invention relates to a kind of indoor set of air conditioner, particularly a kind of have heat exchanger and refrigerant loop parts, the indoor set of the air conditioner of air being regulated by means of the condensation-expansion of cold-producing medium.
Background technology
The separate type air conditioner that is divided into indoor set and off-premises station has following two kinds of styles, a kind of air conditioner is to have only an indoor set to be connected a pairing formula air conditioner on the off-premises station, and another kind of air conditioner is that in parallel ining succession connects the how desk-top air conditioner of many indoor sets on the off-premises station.
Fig. 1 illustrates the outside drawing of pairing formula air conditioner.81, one off-premises stations of the air conditioner here, 82 corresponding indoor sets 83, the connecting portion 89 that is made of refrigerant piping and transfer line is connected 82 and 83 these two parts.
As shown in Figure 2, the indoor set of pairing formula air conditioner is made of fan runner 3, heat exchanger 4 and electronic device mounting box 30.These component parts are arranged in the housing that is made of preceding grid component 10, front panel 11 and after-poppet 12.After-poppet 12 is installed on the suspension plate 15 that is fixed on the indoor wall, is fixed on the indoor wall.Be provided with narrow slit shape top air entry 10a on the upper surface of preceding grid component 10, plate 11 tops and side are provided with preceding air entry 11a in front.The air cleaner 17 that is used for peace and quiet air is arranged in these air entries 10a, 11a inboard.In addition, exhaust outlet has been formed at the bottom in preceding grid component 10 fronts, and the air stream that fan runner 3 produces is discharged from exhaust outlet.
Fan runner 3 is arranged in the fan accommodation section 12a that forms on the after-poppet 12, and the one end is installed on the after-poppet 12 by bearing 13, and its other end is connected with the turning cylinder of motor 14.This motor 14 is fixed on the after-poppet 12 by means of fixed motor part 16.
Heat exchanger 4 is arranged to round the place ahead of fan runner 3, top and rear portion top, and is divided into front side heat exchange department 141 and the rear side heat exchange department 142 that effective length is L.Each heat exchange department the 141, the 142nd has been installed the parts of many fin on the heat-transfer pipe after two ends, the left and right sides repeatedly bend.After fan runner 3 rotates,,, and between cold-producing medium that flows through heat-transfer pipe inside and air, carry out heat exchange by fan runner 3 from top air entry 10a and the air-breathing air of front suction gas port 11a.Heat exchanger 4 is connected with the refrigerant tubing that stretches out from off-premises station by refrigerant tubing.In addition, in the arranged beneath of front side heat exchange department 141 condensed water connect dish assembly 18, this condensed water connects and connects dish before dish assembly 18 comprises and regulate the blade of discharging direction of air etc.
The front side heat exchange department of heat exchanger and the effective length of rear side heat exchange department also can be inequality.For example, open shown in the 2001-82795 communique as the spy, the front side heat exchange department of heat exchanger wherein and the effective length of rear side heat exchange department can be inequality.
The indoor set that the indoor set of the pairing formula air conditioner shown in above-mentioned Fig. 1 and Fig. 2 and off-premises station are connected in parallel and are adopted on the how desk-top air conditioner of many indoor sets all designed respectively in the past separately.At this present situation, in recent years, the researcher is just attempting to realize the generalization of parts between pairing formula indoor set and how desk-top indoor set.In most cases match formula and how desk-top in the specification of heat exchanger be inequality, but think that housing etc. partly can generalization.
But, in the indoor set of the how desk-top air conditioner different,, perhaps it is carried out various controls because many indoor sets will start separately and shut down with the pairing formula, mostly motor-driven valve is set in inside.The main effect of this motor-driven valve is a refrigerant amount of regulating the heat exchanger that flows to indoor set, when the cold-producing medium of gas, liquid admixture expands, all can send bigger noise.
If the peculiar parts of how desk-top indoor set, be that noise sources such as motor-driven valve are arranged in the housing of common pairing formula indoor set, then in the indoor set of pairing formula, will its centralized arrangement in centralized arrangement in the space of heat exchanger side of refrigerant pipe group.At this moment, if use identical housing, the indoor set for the pairing formula can not produce noise, but for how desk-top indoor set, and then the noise of motor-driven valve etc. will inevitably leak into indoor.Therefore, pairing formula indoor set and the used parts such as housing of how desk-top indoor set are difficult to general.
Summary of the invention
Even the object of the present invention is to provide a kind of becoming under the situation of refrigerant loop arrangements of components such as motor-driven valve in indoor set of noise source, can not allow noise leakage arrive the indoor set outside yet, and can avoid the obstructed over-heat-exchanger of air and flow into the indoor set of the air conditioner of fan runner.
The indoor set that the indoor set of the described air conditioner of first aspect present invention utilizes the condensation-expansion of cold-producing medium that air is regulated, it possesses heat exchanger, fan runner, refrigerant loop parts and dividing plate.Heat exchanger is parts of implementing heat exchange between cold-producing medium and air, and it has front side heat exchange department and rear side heat exchange department.The effective length ratio front side heat exchange department of rear side heat exchange department is short.The fan runner is used for being sent to the air after regulating indoor.The refrigerant loop parts are the parts that change flow of refrigerant, that is, and and electric expansion valve and current divider etc.The refrigerant loop arrangements of components is in the different spaces that produce of effective length owing to front side heat exchange department and rear side heat exchange department.Baffle arrangement prevents that air from leaking into said fans runner space on every side from above-mentioned space between the space around above-mentioned space and the said fans runner.
Here, at first make the effective length weak point of the effective length ratio front side heat exchange department of rear side heat exchange department, so just produce the space of regulation in the back side of indoor set one side.Then, the refrigerant loop arrangements of components that is called motor-driven valve and current divider in this space, because said electric valve and current divider can produce bigger noise when changing flow of refrigerant.Like this, because a refrigerant loop arrangements of components that becomes noise source in the space of the back side of indoor set inside one side, has reduced so leak into the noise content of empty interior machine face one side, reduced the sense of discomfort that is in indoor people.
But, when the effective length of the effective length ratio front side of rear side heat exchange department heat exchange department in short-term, think all that usually the front side heat exchange department that the length that make the fan runner and effective length are grown is complementary.Like this, above-mentioned space (space that is produced by the difference of the effective length of front side heat exchange department and rear side heat exchange department) will be adjacent with a fan runner part.At this moment, if between this space and fan runner any parts are not set, probably air can not pass through heat exchanger, but directly flows to the fan runner from above-mentioned space.
For this reason, in the described indoor set of first aspect present invention,, flow into the fan runner so can avoid the obstructed over-heat-exchanger of air because between space that the refrigerant loop parts are set and fan runner, be provided with dividing plate.
The indoor set of the described air conditioner of second aspect present invention is on the basis of first aspect, also has off-premises station and many indoor sets.And, be arranged in because of the refrigerant loop parts in the short space that forms of the effective length of the effective length ratio front side heat exchange department of rear side heat exchange department and comprise motor-driven valve at least.Motor-driven valve is to be provided with for refrigerant amount that adjusting flows to many indoor sets.
Here, what is called is contained in the indoor set inside of how desk-top air conditioner, exactly some motor-driven valves is arranged in the space of the back side one side of indoor set inside of easy obstruct noise.Though when motor-driven valve is regulated refrigerant amount, can produce bigger noise,, can not hear very big noise so be in indoor people because it is arranged in noise is not easy to drain in the above-mentioned space of going the indoor set outside.
The indoor set of the described air conditioner of third aspect present invention be first or the basis of second aspect on, also have the metal parts that covers the space of arranging the refrigerant loop parts with aforementioned barriers.
Here, after the refrigerant loop arrangements of components is in the space of the back side of indoor set inside one side, not only can suppresses the volume of noise leakage, but also cover above-mentioned space with metal parts to the positive side of indoor set.Therefore, even what produced by the cryogen circuit parts, can penetrate the shell that mostly is formed from a resin and to the noise that leaks into the indoor set outside under the very big situation of the noise of letting out the indoor set external leaks, because the soundproof effect of crown cap also can be reduced to very little.
The indoor set of the described air conditioner of fourth aspect present invention is that aforementioned barriers comprises: the last lower clapboard that is positioned at the top of said fans runner first to the basis of the either side of the third aspect; And the left and right sides dividing plate that forwards extends from the end of above-mentioned space one side of above-mentioned rear side heat exchange department.
The indoor set of the described air conditioner of sixth aspect present invention is on the basis of fourth aspect, also has drainage channel, prevents that condensed water from dropping onto space around the fan runner from the staggered part of last lower clapboard and left and right sides dividing plate.
The lower end of aforementioned barriers extends to drip tray always, therefore, drops onto water on the dividing plate from heat exchanger etc., can flow in the drip tray that is always using in the prior art.Like this, just can prevent that sealing drops onto on the fan runner from the staggered part of last lower clapboard and left and right sides dividing plate.

As Fig. 5 and shown in Figure 6, in indoor set 93, the indoor heat converter 4a that covers the place ahead, top and the rear part of fan runner 3 mainly is made of front side heat exchange department 41 and rear side heat exchange department 42.The effective length of the effective length ratio front side heat exchange department 41 of rear side heat exchange department 42 is short, and the end 42b of its motor 14 1 sides is than the central part (with reference to Fig. 5) of the width of the more close indoor set 93 of end 41b of front side heat exchange department 41.Therefore, on the outside (sides of motor 14 sides) of rear side heat exchange department 42, can guarantee bigger space S P.The width dimensions of this space S P roughly equates with the size of the difference of the effective length of front side heat exchange department 41 and rear side heat exchange department 42, can be 100mm-150mm.
In addition, the structure that the upper end 41a of indoor set 93 employing front side heat exchange departments 41 and the upper end 42a of rear side heat exchange department 42 separate is slightly supporting connecting plate 43 therebetween.This connecting plate 43 is linking into an integrated entity front side heat exchange department 41 and rear side heat exchange department 42, when constituting indoor heat converter 4a, also play preventing air, and directly flow to the effect of the fan runner 3 of below from the top of indoor heat converter 4a not by front side heat exchange department 41 and rear side heat exchange department 42.
And, in indoor set 93, go back motor-driven valve 33a, the refrigerant piping 133 that is connected with motor-driven valve 33a, and make the cold-producing medium that flows out motor-driven valve 33a be diverted to the current divider 39 etc. of each heat-transfer pipe of indoor heat converter 4a, all be arranged in the space that difference produced by the effective length of front side heat exchange department 41 and rear side heat exchange department 42.As shown in Figure 5, maintenance for convenience, motor-driven valve 33a is a lateral arrangement.
Moreover, in indoor set 93, surrounded the space of arranging parts such as motor-driven valve 33a with crown cap 50, last lower clapboard 44 and left and right sides dividing plate 45.Crown cap 50 is sheet metal parts of an integral body, the 1st cover plate 51 by covering space SP top, the 2nd cover plate 52 that extends downwards sideling from the front of the front end edge front side heat exchange department 41 of the 1st cover plate 51, with stretch to declivity from the rear end of the 1st cover plate 51, and the 3rd cover plate 53 at covering space SP rear constitutes.This crown cap 50 mainly is provided with for sound insulation.On the other hand, last lower clapboard 44 and left and right sides dividing plate 45 are in order to prevent that the air in the inflow space SP from letting out and the metal plate-like parts that are provided with from fan runner one side.Last lower clapboard 44 is positioned at the top of fan runner 3, space around the fan runner 3 with arranged that the space S P of motor-driven valve 33a etc. separates.Left and right sides dividing plate 45 is vertically extending forward from the end 42b of space S P one side of rear side heat exchange department 42, parts roughly triangular in shape, the end 42b of leg-of-mutton each bar limit and rear side heat exchange department 42, the end of space S P one side of connecting plate 43, and upward the end of lower clapboard 44 vertically connects.
In addition, preceding drip tray 61 and back drip tray 62 are arranged in the below of front side heat exchange department 41 lower ends and the below of rear side heat exchange department 42 lower ends.These two drip trays the 61, the 62nd, with Fig. 2 in the parts that form on the after-poppet of spline structure and drip tray assembly of existing low trestle 12 and drip tray assembly 18, play the effect of accepting the condensed water that drips from indoor heat converter 4a etc.And, in indoor set 93, can be in order to ensure condensed water from above-mentioned lower clapboard 44 and the left and right sides dividing plate 45 gone up round space S P, and drop onto on the fan runner 3 with the cross section of the end 42b of space S P one side of rear side heat exchange department 42, drainage channel 63 below this part, formed.This drainage channel 63 is the alternating share places at last lower clapboard 44 and left and right sides dividing plate 45, metallic plate (is gone up the part of lower clapboard 44, the part of left and right sides dividing plate 45 perhaps is installed in other parts on these dividing plates 44,45) formation of crooked back, the cross section is the parts of bag shaped structure.Therefore, the condensed water that drips down through left and right sides dividing plate 45 from the end 42b of rear side heat exchange department 42, with because of pressure differential from space S P through the gap, cross section from last lower clapboard 44 and left and right sides dividing plate 45, the condensed water that goes out through passing through fan runner 3 effluents, all be imported in the drainage channel 63, flow into then in the drip tray 62 (with reference to Fig. 6).
The feature of<indoor set 〉
(1)
In indoor set, at first, make the effective length weak point of the effective length ratio front side heat exchange department 41 of rear side heat exchange department 42, and produce the space S P of regulation in the back side of indoor set 93 side.Can produce the refrigerant loop arrangements of components that is called motor-driven valve 33a and current divider 133 of bigger noise in this space S P during then, the change flow of refrigerant.Like this, because can be arranged in the rear side of indoor set 93 to the noise source of motor-driven valve 33a etc.,, can reduce the decibel of the indoor noise that the people heard so judge from the directionality of sound transmission.
(2)
In indoor set 93, not only the refrigerant loop arrangements of components that motor-driven valve 33a etc. is become noise source is in the space S P of indoor set 93 back sides one side, suppressing to leak into the volume of indoor set 93 positive sides, but also with crown cap 43 covering space SP.Thereby, even the high-decibel noise that is produced by 33a such as motor-driven valves can penetrate common shell by resin manufacture, leak under the situation of indoor set 93 outsides, because the soundproof effect of crown cap 43 has been arranged, just can suppress the outside of this noise leakage to indoor set 93.
In addition, preferably use with the sound insulation means that cover the available technology adopting of motor-driven valve 33a with putty or rubber.
(3)
In indoor set 93, because the effective length of the effective length ratio front side heat exchange department 41 of rear side heat exchange department 42 is short, so the length of the fan runner 3 suitable with the effective length of front side heat exchange department 41 is longer than the length of rear side heat exchange department 42.Like this, space S P is located in the top of a part of motor 14 sides of fan runner 3.
In the case, if between space S P and fan runner 3, do not establish any parts, will there be free flow of QI being obstructed to cross in each heat exchange department 41,42 of indoor heat converter 4a any one, but directly flows to the danger of fan runner 3 from space S P.
For this reason, in indoor set 93, between space S P that arranges motor-driven valve 33a etc. and fan runner 3, last lower clapboard 44 and left and right sides dividing plate 45 have been arranged, do not flow through indoor heat converter 4a so can prevent air, and directly flow to the phenomenon generation of fan runner 3 from space S P.
(4)
In indoor set 93, last lower clapboard 44 has prevented that air from flowing to fan runner 3 downwards from space S P, and left and right sides dividing plate 45 has prevented that air from flowing to fan runner 3 between the end 42b of space S P by front side heat exchange department 41 and rear side heat exchange department 42.And, as shown in Figure 6, because go up the top that the lower end of lower clapboard 44 and left and right sides dividing plate 45 is positioned at drip tray 62, so even water droplet is when the end 42b of rear side heat exchange department 42 etc. flows on the dividing plate 44,45, these water also can flow in the drip tray 62.
In addition, because the difference that is stressed waits influence, flow to dripping of fan runner 3 sides through the gap from the end 42b of the rear side heat exchange department 42 shorter and the alternating share of two dividing plates 44,45, then by drainage channel 63 guiding drip trays 62 than fan runner 3.Therefore, as mentioned above, even be provided with space S P, and surround under the situation of space S P with dividing plate 44,45, dripping can not drop onto on the fan runner 3 yet.
(5)
The indoor set 93 that possesses motor-driven valve 33a is difficult to intactly use on the indoor set of pairing formula air conditioner.But, structurally can replace matching the indoor heat converter of formula used for indoor machine with the heat exchanger 4a of indoor set 93, and between how desk-top and pairing formula air conditioner, realize the generalization of shell.
For example, aspect the generalization of shell, how desk-top indoor set for office usefulness, can be as above-mentioned indoor set 93, the heat exchange department indoor heat converter different with the effective length of rear side heat exchange department in front side is set, and, the heat exchange department indoor heat converter identical with the effective length of rear side heat exchange department in front side can be set then for pairing formula indoor set.
If use heat exchanger of the present invention, the effective length of the effective length ratio front side heat exchange department of rear side heat exchange department is short, produces the space of regulation in the back side of indoor set one side.And, can produce bigger noise when changing flow of refrigerant, the refrigerant loop arrangements of components that is called motor-driven valve and current divider is in this space.Therefore, the noise content that leaks into the indoor set front has seldom reduced the sense of discomfort that is in indoor people.
