Description

空気調和装置の吊りバンドAir conditioner hanging band
  本発明は、空気調和装置の吊りバンドに関し、特に、冷媒配管の冷媒配管を取り付ける吊りバンドに係るものである。 The present invention relates to a suspension band of an air conditioner, and particularly relates to a suspension band to which a refrigerant pipe of a refrigerant pipe is attached.
  従来、空気調和装置には、特許文献に開示されているように、室外ユニットに複数の室内ユニットが接続されてビルに設置されるものがある。ビルの躯体が完成した後に空気調和装置を据え付ける際には、配管接続などの多くが現地で行われる。また、その際、冷媒配管は、吊りバンドによってビルの躯体に取り付けられる。 Conventionally, some air conditioners are installed in a building by connecting a plurality of indoor units to an outdoor unit as disclosed in the patent literature. When the air conditioner is installed after the building's enclosure is completed, many pipe connections are made locally. At that time, the refrigerant pipe is attached to the building frame by a suspension band.

    -空気調和装置(10)の施工方法-
  次に、上記空気調和装置(10)の施工方法である施工手順について説明する。そして、この施工方法には、気密試験方法も含まれている。
-Construction method of air conditioner (10)-
Next, a construction procedure that is a construction method of the air conditioner (10) will be described. This construction method also includes an airtight test method.
  先ず、上記空気調和装置(10)の施工は、図10に示すように、施工工事の受注後における建築図面の提供から始まり、例えば、ビル(11)の設計図面の提供から始まる。 First, as shown in FIG. 10, the construction of the air conditioner (10) starts with provision of architectural drawings after receiving an order for construction work, for example, provision of design drawings of the building (11).
  上記空気調和装置(10)の施工は、プラニング工程(M1)とパーツ加工工程(M2)と設置工程(M3)とを備え、上記プラニング工程(M1)は、図11に示すように、設計図面提供工程(M11)と配管図面作成工程(M13)と決定工程(M14)とを備えている。 The construction of the air conditioner (10) includes a planning process (M1), a parts processing process (M2), and an installation process (M3). The planning process (M1) is a design drawing as shown in FIG. A providing step (M11), a piping drawing creating step (M13), and a determining step (M14) are provided.
  上記プラニング工程(M1)は、上記空気調和装置(10)が設置されるビル(11)の設計図面に基づいて配管図面を作成し、上記冷媒回路(40)の工場施工部と現地施工部とを決定する工程である。 The planning step (M1) is to create a piping drawing based on the design drawing of the building (11) where the air conditioner (10) is installed. This is a step of determining.
  上記プラニング工程(M1)は、図11に示すように、設計図面が提供される設計図面提供工程(M11)から始まり、現地調査工程(M12)を介して配管図面作成工程(M13)に移行する場合と、現地情報を入手しつつ上記配管図面作成工程(M13)を実行する場合がある。 As shown in FIG. 11, the planning process (M1) starts from a design drawing providing process (M11) in which a design drawing is provided, and proceeds to a piping drawing creating process (M13) through an on-site investigation process (M12). In some cases, the piping drawing creation step (M13) may be executed while obtaining local information.
  つまり、更新工事の場合、既設のビル(11)が存在するので、ビル(11)の現地調査を行い、梁などの実際のビル(11)の構造を調査する。この現地調査工程(M12)から配管図面作成工程(M13)に移り、実際のビル(11)の構造に基づき上記配管図面を作成する。 In other words, in the case of renewal work, there is an existing building (11), so we will conduct a field survey of the building (11) and investigate the structure of the actual building (11) such as beams. From this field survey process (M12), the process moves to the piping drawing creation process (M13), and the piping drawing is created based on the actual structure of the building (11).
  一方、新築工事の場合、ビル(11)の現地調査を行うことができないので、設計図面が提供されると、新築工事の進行に伴って現地情報を入手しつつ配管図面作成工程(M13)を実行し、ビル(11)の工事の進行に伴って上記配管図面を作成する。 On the other hand, in the case of new construction work, the site survey of the building (11) cannot be conducted, so when the design drawings are provided, the piping drawing creation process (M13) is performed while obtaining local information as the new construction works. Execute and create the above piping drawings as the construction of the building (11) progresses.
  具体的に、上記設計図面は、例えば、図12に示すように、ビル(11)の各階の平面図に空調配管線図が記入されている。上記設計図面は、室内ユニット(30)のユニット表示(U1)と冷媒配管の線図表示(L1)とが記入されている。 Specifically, in the above design drawing, for example, as shown in FIG. 12, an air-conditioning piping diagram is entered in a plan view of each floor of the building (11). In the design drawing, a unit display (U1) of the indoor unit (30) and a diagram display (L1) of the refrigerant pipe are entered.
  一方、上記配管図面は、図13に示すように、設計図面に基づき、現地調査等から工場施工部のパーツ(42)を決定し、該各パーツ(42)に対応したパーツ表示(P1~P8)を組み合わせた配管系統を示す詳細図面である。具体的に、上記第1~第5のパーツ表示(P1~P5)は、直管の折曲げおよび湾曲を示したパーツ(42)を示し、図示しないが、長さ等が示されている。また、上記第6および第7のパーツ表示(P6,P7)は、分岐継手部(55)に延長配管(56)を接続したパーツ(42)を示し、図示しないが、長さ等が示されており、上記第6のパーツ表示(P6)は、例えば、図2~図4に示した配管ユニット(50)を示している。また、第8のパーツ表示(P8)は、立ち上がり用のパーツ(42)を示し、図示しないが、長さ等が示されている。 On the other hand, as shown in FIG. 13, the piping drawing is based on the design drawing, the part (42) of the factory construction department is determined from field surveys, etc., and the parts display (P1 to P8) corresponding to each part (42) is determined. It is a detailed drawing which shows the piping system which combined. Specifically, the first to fifth part indications (P1 to P5) show the part (42) showing the bending and bending of the straight pipe, and although not shown, the length and the like are shown. The sixth and seventh part indications (P6, P7) show the part (42) in which the extension pipe (56) is connected to the branch joint part (55). Although not shown, the length and the like are shown. The sixth part display (P6) shows, for example, the piping unit (50) shown in FIGS. The eighth part display (P8) shows the rising part (42), which is not shown, but shows the length and the like.
  上記配管図面作成工程(M13)に続いて決定工程(M14)に移り、複数のパーツ(42)に対応して色分け等の区別表示を行う。つまり、上記冷媒回路(40)の冷媒配管(41)は、直管や配管ユニット(50)等のパーツ(42)で構成されているので、取付箇所に対応してパーツ(42)の区別表示を行う。 After the above piping drawing creation process (M13), the process moves to the determination process (M14), and a color classification or the like is displayed corresponding to the plurality of parts (42). That is, since the refrigerant pipe (41) of the refrigerant circuit (40) is composed of parts (42) such as a straight pipe and a pipe unit (50), the parts (42) are displayed in a distinguishable manner corresponding to the mounting location. I do.
  例えば、図4および図5に示すように、上記配管ユニット(50)は、両端部に巻き付けられた赤などの色付きのテープ(57)に対応した区別表示を行うので、上記決定工程(M14)は、色分けに基づいたパーツ(42)の設置箇所を示す指示書を作成する。つまり、施工者が各パーツ(42)の設置箇所を理解できるように、書面で各パーツ(42)の設置箇所を示す。例えば、図4および図5に示すように、配管ユニット(50)の両端部に付された色および番号を指示書に示す。 For example, as shown in FIG. 4 and FIG. 5, the pipe unit (50) performs a distinction display corresponding to a colored tape (57) wound around both ends, so that the determination step (M14) Creates an instruction sheet indicating the installation location of the part (42) based on the color coding. That is, the installation location of each part (42) is shown in writing so that the installer can understand the installation location of each part (42). For example, as shown in FIG. 4 and FIG. 5, the color and number given to both ends of the piping unit (50) are shown in the instruction sheet.
  上記プラニング工程(M1)に続いてパーツ加工工程(M2)に移り、工場施工部に対応した冷媒回路(40)の複数のパーツ(42)を工場において作製する。 After the planning process (M1), the process moves to the parts processing process (M2), and a plurality of parts (42) of the refrigerant circuit (40) corresponding to the factory construction department are produced in the factory.
  つまり、上記パーツ加工工程(M2)は、加工工程(M21)と気密試験工程(M22)と保温工程(M23)とを備えている。そして、上記加工工程(M21)は、上記配管図面に基づき、各パーツ(42)を作製し、設置箇所を示す色分けおよび番号等の区別表示を付することになる。具体的に、上記パーツ(42)の1つである配管ユニット(50)などを作製する。例えば、分岐管の配管ユニット(50)は、短管部(55b)と継手部(56)とをロー付けによって接続して液管(51)とガス管(52)とを作製する。つまり、この配管ユニット(50)は、工場で作製されるので、火を用いたロー付け作業が行われる。 That is, the part machining step (M2) includes a machining step (M21), an airtightness test step (M22), and a heat retention step (M23). And the said process (M21) produces each part (42) based on the said piping drawing, and attaches | subjects distinction display, such as a color classification and a number which show an installation location. Specifically, the piping unit (50) which is one of the parts (42) is produced. For example, the branch pipe piping unit (50) connects the short pipe portion (55b) and the joint portion (56) by brazing to produce a liquid pipe (51) and a gas pipe (52). That is, since this piping unit (50) is manufactured at a factory, a brazing operation using fire is performed.
  上記加工工程(M21)に続いて、気密試験工程(M22)を実行し、例えば、断熱部材(54)を施す前の配管本体(53)が作製されると、窒素ブローの気密試験を行う。 Subsequent to the above processing step (M21), an airtightness test step (M22) is executed. For example, when a pipe body (53) before applying the heat insulating member (54) is produced, an airtight test of nitrogen blow is performed.
  上記気密試験工程で各パーツ(42)の気密が保持されていると、保温工程(M23)に移り、各パーツ(42)に断熱部材(54)を施す。例えば、上記配管ユニット(50)は、上記液管(51)とガス管(52)とをそれぞれ断熱部材(54)によって被覆し、この断熱部材(54)が被覆された液管(51)とガス管(52)とを一体に固定して配管ユニット(50)の作製が終了する。なお、上記配管ユニット(50)の一端は、嵌め込み式の接続継手(43)が取り付けられる。 When the airtightness of each part (42) is maintained in the above airtightness test process, the process proceeds to the heat insulation process (M23), and the heat insulating member (54) is applied to each part (42). For example, the piping unit (50) covers the liquid pipe (51) and the gas pipe (52) with a heat insulating member (54), respectively, and the liquid pipe (51) covered with the heat insulating member (54) The production of the piping unit (50) is completed by fixing the gas pipe (52) together. In addition, a fitting connection joint (43) is attached to one end of the piping unit (50).
  上記配管ユニット(50)は、設置箇所を示す色付きのテープ(57)によって液管(51)とガス管(52)とを一体に固定されるとともに、番号を付する。 The pipe unit (50) has a liquid pipe (51) and a gas pipe (52) fixed integrally with a colored tape (57) indicating an installation location, and numbered.
  なお、上記工場施工部において、各パーツ(42)の長さは、4m未満に設定されている。つまり、直管のパーツ(42)であっても4m未満に設定されている。一般用エレベータは、主として開口(幅)が2150mmであり、奥行きが1600mmであり、高さが2300mmであり、対角長さが3467mmである。したがって、各パーツ(42)の長さは、4m未満とし、一般用エレベータの搬送を可能にしている。逆に、パーツ(42)が4m以上の長さになると、このパーツ(42)は、階段による搬送を行わなければならなくなる。 In addition, in the above-mentioned factory construction department, the length of each part (42) is set to less than 4 m. That is, even the straight pipe part (42) is set to be less than 4 m. The general elevator has an opening (width) of 2150 mm, a depth of 1600 mm, a height of 2300 mm, and a diagonal length of 3467 mm. Therefore, the length of each part (42) shall be less than 4 m, and the general elevator can be conveyed. Conversely, when the part (42) is 4 m or longer in length, the part (42) must be transported by stairs.
  上記パーツ加工工程(M2)に続いて設置工程(M3)に移り、パーツ加工工程(M2)で作製した複数のパーツ(42)および上記プラニング工程(M1)で決定した現地施工部に対応した冷媒回路(40)の複数の機器、つまり、配管ユニット(50)、室外ユニット(20)および室内ユニット(30)をビル(11)に設置する。 Following the parts machining process (M2), the process moves to the installation process (M3), where the refrigerant corresponding to the multiple parts (42) produced in the parts machining process (M2) and the local construction department determined in the planning process (M1) A plurality of devices of the circuit (40), that is, the piping unit (50), the outdoor unit (20), and the indoor unit (30) are installed in the building (11).
  具体的に、室内機工程(M31)から始まり、室内機である室内ユニット(30)の吊込みが行われ、室内ユニット(30)を各室内の天井に設置する。その後、上記室内機工程(M31)から配管工程(M32)に移り、直管である竪管などが取り付けられる。 Specifically, starting from the indoor unit process (M31), the indoor unit (30) that is an indoor unit is suspended, and the indoor unit (30) is installed on the ceiling of each room. Thereafter, the indoor unit process (M31) moves to the piping process (M32), and a straight pipe or the like is attached.
  この配管工程(M32)においては、上記工場で加工した配管ユニット(50)および直管を接続する。その際、上記配管ユニット(50)と直管との接続は、全て嵌め込み式の接続継手(43)が用いられ、つまり、火を用いたロー付け作業等は行われない。また、上記冷媒配管(41)は、吊りバンド(60)によって天井に取り付けられる。 In this piping process (M32), the piping unit (50) and straight pipe processed in the above factory are connected. At that time, the fitting unit (43) is used for the connection between the pipe unit (50) and the straight pipe, that is, no brazing work using fire is performed. The refrigerant pipe (41) is attached to the ceiling by a suspension band (60).
  上記配管工程(M32)が終了すると、室外機工程(M33)に移り、室外機である室外ユニット(20)が設置される。その後、上記室外機工程(M33)から配管工程(M34)に移り、室外機廻りの配管工事が行われる。その際においても、全て嵌め込み式の接続継手(43)が用いられ、つまり、火を用いたロー付け作業等は行われない。 When the piping process (M32) is completed, the process proceeds to the outdoor unit process (M33), and the outdoor unit (20), which is an outdoor unit, is installed. Thereafter, the process moves from the outdoor unit process (M33) to the piping process (M34), and piping work around the outdoor unit is performed. Even in that case, the fitting type connection joint (43) is used, that is, the brazing operation using fire is not performed.
  上記配管工程(M34)が終了すると、気密試験工程(M35)に移り、冷媒回路(40)は、窒素ブローの気密試験が行われる。つまり、上記接続継手(43)などからの漏れがないか否かの気密試験が行われる。この気密試験は、冷媒系統(1A,1B,1C)を複数に区分して行われる。 When the piping process (M34) is completed, the process proceeds to an airtight test process (M35), and the refrigerant circuit (40) is subjected to a nitrogen blow airtight test. That is, an airtight test is performed to determine whether or not there is a leak from the connection joint (43). This airtight test is performed by dividing the refrigerant system (1A, 1B, 1C) into a plurality of sections.
  この気密試験で冷媒回路(40)の気密が保持されていると、保温工程(M36)に移り、直管等に断熱部材(図示省略)が施される。配管施工が終了する。 If the airtightness of the refrigerant circuit (40) is maintained in this airtightness test, the process moves to the heat retaining step (M36), and a heat insulating member (not shown) is applied to the straight pipe or the like. Piping work is completed.
    -実施形態の効果-
  以上のように、本実施形態によれば、プラニング工程(M1)において冷媒回路(40)の工場施工部と現地施工部とを決定し、冷媒回路(40)の各パーツ(42)を工場で作製するので、施工日程の大幅な短縮を図ることができる。つまり、従来、現地において接続作業等が行われていたのに代わり、工場において作業が行われるので、狭い天井裏の作業等を簡単に行うことができ、施工日程が大幅に短縮される。
-Effects of the embodiment-
As described above, according to the present embodiment, the factory construction part and the local construction part of the refrigerant circuit (40) are determined in the planning step (M1), and each part (42) of the refrigerant circuit (40) is determined at the factory. Since it is produced, the construction schedule can be greatly shortened. That is, since the work is performed in the factory instead of the connection work or the like conventionally performed in the field, the work of a narrow ceiling can be easily performed, and the construction schedule is greatly shortened.
  また、上記冷媒回路(40)の施工の多くを工場施工部とすることができるので、現地では火を用いた作業が低減し、現地の火災事故を削減することができる。また、断熱作業も工場で行うことができるので、断熱作業の精度を大幅に向上させることができ、結露を防止することができる。 Also, since most of the construction of the refrigerant circuit (40) can be made into a factory construction department, work using fire can be reduced locally, and local fire accidents can be reduced. Moreover, since the heat insulation work can also be performed in the factory, the accuracy of the heat insulation work can be greatly improved, and condensation can be prevented.
  また、設計図面から冷媒回路(40)の配管図面を作成するので、工場施工部の精度を向上させることができ、配管作業の多くを工場で行うことができる。この結果、施工日程の大幅な短縮をより確実に図ることができる。 Also, since the piping drawing of the refrigerant circuit (40) is created from the design drawing, the accuracy of the factory construction department can be improved, and much of the piping work can be performed at the factory. As a result, the construction schedule can be significantly shortened more reliably.
  特に、上記配管図面は、現地調査等を行って作成するので、工場施工部の精度をより向上させることができ、施工日程の大幅な短縮をより確実に図ることができる。 Especially, since the above piping drawings are created through field surveys, etc., the accuracy of the factory construction department can be further improved, and the construction schedule can be greatly shortened more reliably.
  また、上記配管図面に各パーツ(42)を区別表示を行うので、各パーツ(42)の設置箇所が明確化され、現地施工の簡略化を図ることができ、施工日程の大幅な短縮をより確実に図ることができる。 In addition, because each part (42) is displayed in a distinguishing manner on the above piping drawing, the installation location of each part (42) can be clarified, the on-site construction can be simplified, and the construction schedule can be greatly shortened. It can be done reliably.
  また、区別表示されたパーツ(42)の設置箇所を示す指示書を作成するので、誤接続等を確実に抑制することができることから、現地施工の精度を向上させることができる。 In addition, since an instruction sheet indicating the installation location of the separately displayed parts (42) is created, erroneous connection and the like can be reliably suppressed, so that the accuracy of on-site construction can be improved.
  また、上記各パーツ(42)におけるロー付け作業は、工場のみで行われ、現地施工の接続は、嵌め込み式の接続継手(43)を用いた作業のみが行われるので、火を用いた作業が工場のみに限定され、現地では火を用いた作業がなくなる。この結果、現地の火災事故を皆無にすることができる。その上、工場においてロー付け作業を行うので、嵌め込み式の接続継手(43)を用いる箇所が少なくなり、高価な接続継手(43)を少なくすることができることから、工費の低減を図ることができる。 In addition, the brazing work on each part (42) is performed only at the factory, and the connection for on-site construction is performed only using the fitting-type connection joint (43). It is limited to factories only, and there will be no work using fire on site. As a result, there can be no local fire accidents. In addition, since the brazing operation is performed in the factory, the number of places where the fitting type connection joints (43) are used is reduced, and the number of expensive connection joints (43) can be reduced, so that the construction cost can be reduced. .
  また、上記工場で施工される配管ユニット(50)は、断熱部材(54)の被覆が工場において行われているので、現地における断熱部材(54)の被覆が大幅に軽減される。この結果、断熱作業の精度を大幅に向上させることができるので、結露を確実に防止することができる。特に、この結露は、施工後に1年以上が経過してから生ずる場合があるが、上記配管ユニット(50)は、この結露の防止に極めて有効である。 Also, since the piping unit (50) constructed in the factory is covered with the heat insulating member (54) in the factory, the coating of the heat insulating member (54) at the site is greatly reduced. As a result, the accuracy of the heat insulation work can be greatly improved, so that condensation can be reliably prevented. In particular, this condensation may occur after one year or more after construction, but the piping unit (50) is extremely effective in preventing this condensation.
  また、上記工場で施工される配管ユニット(50)は、気密試験が工場で行われているので、現地の気密試験を簡略にすることができる。つまり、現地の気密試験で漏洩箇所が判明した場合においても配管ユニット(50)の漏洩箇所はないので、漏洩箇所の判明が容易になる。 Also, the piping unit (50) constructed in the above factory is subjected to an airtight test at the factory, so that the local airtight test can be simplified. That is, even when a leak location is found by an on-site airtight test, there is no leak location of the piping unit (50), so that the leak location is easily identified.
  また、上記吊りバンド(60)のバンド本体(61)に汎用バンドを用いることができるので、現地の施工を極めて簡略にすることができる。 Moreover, since a general-purpose band can be used for the band body (61) of the suspension band (60), the construction at the site can be greatly simplified.
  また、上記バンド本体(61)に複数の取付孔(64)を設けているので、1種類のバンド本体(61)によって太さの異なる冷媒配管(41)にも対応することができる。 Further, since a plurality of mounting holes (64) are provided in the band main body (61), it is possible to cope with refrigerant pipes (41) having different thicknesses by one type of band main body (61).
  また、上記バンド継手(62)がビル(11)に取り付けられるので、バンド本体(61)の締結とビル(11)への取付けとを1つの部材で行うことができる。 Also, since the band joint (62) is attached to the building (11), the band body (61) can be fastened and attached to the building (11) with a single member.
