以下、この発明の実施の形態１を図について説明する。図１はこの発明の実施の形態１による熱交換器の空気調和機組込時断面図である。図において、１は前面側熱交換器、２は後面側熱交換器、３は前記熱交換器の伝熱管、４は前記熱交換器のフィンであり、前記各熱交換器１，２は複数枚のフィン４に複数の伝熱管３を垂直に貫通し嵌合させて構成されており、伝熱管３の内部には冷媒を、フィン４間には空気を流通させ、空気を冷却・加熱するものである。前記熱交換器を空気調和機に組み込む場合、空気調和機の大きさを変えることなく高性能化を可能とするために、前記熱交換器を多段に折り曲げて伝熱面積の増加による高性能化を図ったものである。 Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of an air conditioner built in a heat exchanger according to Embodiment 1 of the present invention. In the figure, 1 is a front side heat exchanger, 2 is a rear side heat exchanger, 3 is a heat transfer tube of the heat exchanger, 4 is a fin of the heat exchanger, and each of the heat exchangers 1 and 2 is plural. A plurality of heat transfer tubes 3 are vertically penetrated and fitted to the fins 4, and refrigerant is circulated inside the heat transfer tubes 3, air is circulated between the fins 4, and the air is cooled and heated. Is. When incorporating the heat exchanger into an air conditioner, the heat exchanger can be bent in multiple stages to increase performance without changing the size of the air conditioner.

７は吸い込みグリル、８はフィルター、９は風路、１０は吹き出し口、１１は吸い込み空気、１２は吹き出し空気、１３は送風機である。本実施の形態による熱交換器は、前記前面側熱交換器１及び後面側熱交換器２の一部を１列にて構成している。   7 is a suction grille, 8 is a filter, 9 is an air passage, 10 is a blowout port, 11 is suction air, 12 is blown air, and 13 is a blower. In the heat exchanger according to the present embodiment, a part of the front side heat exchanger 1 and the rear side heat exchanger 2 is configured in one row.

前記空気調和機においては、室内空気は送風機１３の運転により、吸い込みグリル７より吸い込まれフィルター８を通過し、熱交換器１，２へ導かれ、前記熱交換器１，２の伝熱管３内を流れる冷媒により冷却・加熱される。この冷却・加熱された空気は吹き出し口より室内に供給され、室内の空調を行うものである。この場合、送風機１３により吸い込まれる空気の量は吸い込みグリル７やフィルター８及び熱交換器１，２の圧力損失の低減により増加し、その結果高性能化が可能となる。   In the air conditioner, the indoor air is sucked from the suction grille 7 through the filter 8 and led to the heat exchangers 1 and 2 by the operation of the blower 13, and is guided into the heat transfer tubes 3 of the heat exchangers 1 and 2. It is cooled and heated by the refrigerant flowing through. This cooled and heated air is supplied into the room from the outlet and performs air conditioning in the room. In this case, the amount of air sucked by the blower 13 is increased by reducing the pressure loss of the suction grill 7, the filter 8, and the heat exchangers 1 and 2, and as a result, high performance can be achieved.

本実施の形態による熱交換器では、前記前面側熱交換器１又は後面側熱交換器２の一部を１列にて構成しているため、熱交換器の圧力損失を低減出来、送風量を増加することが可能となり、伝熱面積の減少による性能低下が抑制されるため、性能を維持しつつ、前記熱交換器のコストを低減することが可能となり、かつ、生産性も向上する。   In the heat exchanger according to the present embodiment, a part of the front-side heat exchanger 1 or the rear-side heat exchanger 2 is configured in one row, so that the pressure loss of the heat exchanger can be reduced, and the blast volume Therefore, it is possible to reduce the cost of the heat exchanger while maintaining the performance, and to improve the productivity.

実施の形態２．
以下、この発明の実施の形態２を図について説明する。図２はこの発明の実施の形態２による熱交換器の正面図である。図において、３は前記熱交換器の伝熱管、４は前記熱交換器のフィンであり、前記熱交換器は複数枚のフィン４に複数の伝熱管３を垂直に貫通し嵌合させて構成されている。
前記複数枚のフィン４は所定のピッチにて積層されており、伝熱管３の内部には冷媒を、フィン間には空気を流通させ、空気を冷却・加熱するものである。 Embodiment 2. FIG.
A second embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a front view of a heat exchanger according to Embodiment 2 of the present invention. In the figure, 3 is a heat transfer tube of the heat exchanger, 4 is a fin of the heat exchanger, and the heat exchanger is configured by vertically penetrating and fitting a plurality of heat transfer tubes 3 to a plurality of fins 4. Has been.
The plurality of fins 4 are laminated at a predetermined pitch. A refrigerant is circulated inside the heat transfer tube 3 and air is circulated between the fins to cool and heat the air.

前記熱交換器を空気調和機に組み込む場合、空気調和機の大きさを変えることなく高性能化を可能とするために、前記熱交換器を多段に折り曲げて伝熱面積の増加による高性能化を図ると共に、実施の形態２による熱交換器は、その一部を１列にするとともに、１列部のフィンピッチＡ１と２列部のフィンピッチＡ２を変化させて構成している。   When incorporating the heat exchanger into an air conditioner, the heat exchanger can be bent in multiple stages to increase performance without changing the size of the air conditioner. In addition, the heat exchanger according to the second embodiment is configured such that a part thereof is arranged in one row and the fin pitch A1 in the first row portion and the fin pitch A2 in the second row portion are changed.

熱交換器の一部を１列にて構成した場合、１列部は２列部より圧力損失は減少するが、圧力損失は熱交換器全面にて均一になるようにバランスしようとするため、その結果、１列部の風速は速くなり、２列部の風速は遅くなる。このような風速分布の不均一が生じると性能は低下し、また、騒音は高くなるため、風速分布を均一にすることが性能向上・騒音低減には不可欠となる。この実施の形態では、圧力損失の低い１列部分のフィンピッチＡ１を圧力損失の高い２列部分のフィンピッチＡ２よりも小さくすることにより、風速分布の均一化を図り、高性能・低騒音化を実現したものである。   When a part of the heat exchanger is configured in one row, the pressure loss in the first row portion is smaller than that in the second row portion, but the pressure loss tries to balance to be uniform over the entire surface of the heat exchanger. As a result, the wind speed in the first row portion is increased, and the wind speed in the second row portion is decreased. When such a nonuniform wind speed distribution occurs, the performance deteriorates and the noise becomes high. Therefore, making the wind speed distribution uniform is indispensable for improving performance and reducing noise. In this embodiment, the fin pitch A1 in one row portion with low pressure loss is made smaller than the fin pitch A2 in two row portions with high pressure loss, thereby achieving uniform wind speed distribution and high performance and low noise. Is realized.

この発明に係る空気調和機の熱交換器は、列数の少ない部分のフィンピッチを、その他の部分のフィンピッチより小さくしたことを特徴とする。   The heat exchanger for an air conditioner according to the present invention is characterized in that the fin pitch in a portion with a small number of rows is made smaller than the fin pitch in other portions.

上記構成により、風速分布が均一化し、高性能・低騒音化が実現できる。   With the above configuration, the wind speed distribution is made uniform, and high performance and low noise can be realized.

実施の形態３．
以下、この発明の実施の形態３を図について説明する。図３はこの発明の実施の形態３による熱交換器の空気調和機組込時断面図である。図において、１は前面側熱交換器、２は後面側熱交換器、３は前記熱交換器の伝熱管、４は前記熱交換器のフィンであり、前記各熱交換器１，２は複数枚のフィン４に複数の伝熱管３を垂直に貫通し嵌合させて構成されており、伝熱管３の内部には冷媒を、フィン４間には空気を流通させ、空気を冷却・加熱するものである。前記熱交換器を空気調和機に組み込む場合、空気調和機の大きさを変えることなく高性能化を可能とするために、前記熱交換器を多段に折り曲げて伝熱面積の増加による高性能化を図ったものである。 Embodiment 3 FIG.
A third embodiment of the present invention will be described below with reference to the drawings. FIG. 3 is a cross-sectional view of the heat exchanger according to Embodiment 3 of the present invention when the air conditioner is incorporated. In the figure, 1 is a front side heat exchanger, 2 is a rear side heat exchanger, 3 is a heat transfer tube of the heat exchanger, 4 is a fin of the heat exchanger, and each of the heat exchangers 1 and 2 is plural. A plurality of heat transfer tubes 3 are vertically penetrated and fitted to the fins 4, and refrigerant is circulated inside the heat transfer tubes 3, air is circulated between the fins 4, and the air is cooled and heated. Is. When incorporating the heat exchanger into an air conditioner, the heat exchanger can be bent in multiple stages to increase performance without changing the size of the air conditioner. Is intended.

７は吸い込みグリル、８はフィルター、９は風路、１０は吹き出し口、１１は吸い込み空気、１２は吹き出し空気、１３は送風機である。本実施の形態による熱交換器は、前記前面側熱交換器１を１列にし、かつ、後面側熱交換器２を２列に構成したものである。   7 is a suction grille, 8 is a filter, 9 is an air passage, 10 is a blowout port, 11 is suction air, 12 is blown air, and 13 is a blower. In the heat exchanger according to the present embodiment, the front side heat exchanger 1 is arranged in one row and the rear side heat exchanger 2 is arranged in two rows.

前記空気調和機においては、室内空気は送風機１３の運転により、吸い込みグリル７より吸い込まれフィルター８を通過し、熱交換器１，２へ導かれ、前記熱交換器１，２の伝熱管３内を流れる冷媒により冷却・加熱される。この冷却・加熱された空気は吹き出し口１０より室内に供給され、室内の空調を行うものである。   In the air conditioner, the indoor air is sucked from the suction grille 7 through the filter 8 and led to the heat exchangers 1 and 2 by the operation of the blower 13, and is guided to the heat exchangers 1 and 2. It is cooled and heated by the refrigerant flowing through. The cooled and heated air is supplied into the room through the blowout port 10 and air-conditions the room.

前記空気調和機において、意匠性改善の観点から前面グリルの幅を狭くした場合、前面側グリルの圧力損失の方が後面側グリルの圧力損失より高くなるが、圧力損失は熱交換器全面にて均一になるようにバランスしようとするため、その結果、前面側の風速は遅くなり、後面側の風速は早くなる。このような風速分布の不均一が生じると性能は低下し、また、騒音は高くなるため、風速分布を均一にすることが性能向上・騒音低減には不可欠となる。本実施の形態では、圧力損失の高い前面側熱交換器１を１列とし、圧力損失の低い後面側熱交換器２を２列にすることにより、風速分布の均一化を図り、高性能・低騒音化を実現したものである。   In the air conditioner, when the width of the front grille is narrowed from the viewpoint of improving the design, the pressure loss of the front grille is higher than the pressure loss of the rear grille. Since it tries to balance so that it may become uniform, as a result, the wind speed of the front side becomes slow, and the wind speed of the rear side becomes fast. When such a nonuniform wind speed distribution occurs, the performance deteriorates and the noise becomes high. Therefore, making the wind speed distribution uniform is indispensable for improving performance and reducing noise. In this embodiment, the front-side heat exchanger 1 with high pressure loss is arranged in one row, and the rear-side heat exchanger 2 with low pressure loss is arranged in two rows, thereby achieving uniform wind speed distribution. Low noise is achieved.

この発明に係る空気調和機の熱交換器は、空気調和機の前面側熱交換器の列数を背面側熱交換器の列数よりも少なくしたことを特徴とする。   The heat exchanger of the air conditioner according to the present invention is characterized in that the number of rows of the front side heat exchanger of the air conditioner is smaller than the number of rows of the back side heat exchanger.

上記構成により、風速分布が均一化し、高性能・低騒音化が実現できる。   With the above configuration, the wind speed distribution is made uniform, and high performance and low noise can be realized.

実施の形態４．
以下、この発明の実施の形態４を図について説明する。図４はこの発明の実施の形態４による熱交換器の空気調和機組込時断面図である。図において、１は前面側熱交換器、２は後面側熱交換器、３は前記熱交換器の伝熱管、４は前記熱交換器のフィンであり、前記各熱交換器１，２は複数枚のフィン４に複数の伝熱管３を垂直に貫通し嵌合させて構成されており、伝熱管３の内部には冷媒を、フィン４間には空気を流通させ、空気を冷却・加熱するものである。前記熱交換器を空気調和機に組み込む場合、空気調和機の大きさを変えることなく高性能化を可能とするために、前記熱交換器を多段に折り曲げて伝熱面積の増加による高性能化を図ったものである。 Embodiment 4 FIG.
Embodiment 4 of the present invention will be described below with reference to the drawings. FIG. 4 is a cross-sectional view of the heat exchanger according to Embodiment 4 of the present invention when the air conditioner is incorporated. In the figure, 1 is a front side heat exchanger, 2 is a rear side heat exchanger, 3 is a heat transfer tube of the heat exchanger, 4 is a fin of the heat exchanger, and each of the heat exchangers 1 and 2 is plural. A plurality of heat transfer tubes 3 are vertically penetrated and fitted to the fins 4, and refrigerant is circulated inside the heat transfer tubes 3, air is circulated between the fins 4, and the air is cooled and heated. Is. When incorporating the heat exchanger into an air conditioner, the heat exchanger can be bent in multiple stages to increase performance without changing the size of the air conditioner. Is intended.

７は吸い込みグリル、８はフィルター、９は風路、１０は吹き出し口、１１は吸い込み空気、１２は吹き出し空気、１３は送風機である。本実施の形態による熱交換器は、前記前面側熱交換器１の下部を２列、上部を１列にし、かつ、後面側熱交換器２を１列に構成したものである。   7 is a suction grille, 8 is a filter, 9 is an air passage, 10 is a blowout port, 11 is suction air, 12 is blown air, and 13 is a blower. In the heat exchanger according to the present embodiment, the lower part of the front heat exchanger 1 is arranged in two rows, the upper part in one row, and the rear heat exchanger 2 is arranged in one row.

前記空気調和機においては、室内空気は送風機１３の運転により、吸い込みグリル７より吸い込まれフィルター８を通過し、熱交換器１，２へ導かれ、前記熱交換器１，２の伝熱管３内を流れる冷媒により冷却・加熱される。この冷却・加熱された空気は吹き出し口より室内に供給され、室内の空調を行うものである。前記空気調和機において、送風機１３に近い前面側熱交換器１の下部の風速は速くなる。このような風速分布の不均一が生じると性能は低下し、また、騒音は高くなるため、風速分布を均一にすることが性能向上・騒音低減には不可欠となる。この実施の形態では、送風機１３に近く風速の速い前面側熱交換器１の下部を２列とし（その他の部分は１列）、下部の圧力損失を増加することで、風速分布の均一化を図り、高性能・低騒音化を実現したものである。   In the air conditioner, the indoor air is sucked from the suction grille 7 through the filter 8 and led to the heat exchangers 1 and 2 by the operation of the blower 13, and is guided into the heat transfer tubes 3 of the heat exchangers 1 and 2. It is cooled and heated by the refrigerant flowing through. This cooled and heated air is supplied into the room from the outlet and performs air conditioning in the room. In the air conditioner, the wind speed at the lower part of the front side heat exchanger 1 close to the blower 13 is increased. When such a nonuniform wind speed distribution occurs, the performance deteriorates and the noise becomes high. Therefore, making the wind speed distribution uniform is indispensable for improving performance and reducing noise. In this embodiment, the lower part of the front-side heat exchanger 1 that is close to the blower 13 and has a high wind speed is arranged in two rows (the other portion is one row), and the pressure loss in the lower portion is increased to make the wind velocity distribution uniform. This achieves high performance and low noise.

この発明に係る空気調和機の熱交換器は、送風機に近い部分の熱交換器の列数を、その他の部分の列数より多くしたことを特徴とする。   The heat exchanger of the air conditioner according to the present invention is characterized in that the number of columns of the heat exchanger in the portion close to the blower is larger than the number of columns in the other portion.

上記構成により、風速分布が均一化し、高性能・低騒音化が実現できる。   With the above configuration, the wind speed distribution is made uniform, and high performance and low noise can be realized.

実施の形態５．
以下、この発明の実施の形態５を図について説明する。図５はこの発明の実施の形態５による熱交換器の側面図である。図において、１は前面側熱交換器、２は後面側熱交換器、３は前記熱交換器の伝熱管、４は前記熱交換器のフィン、５は冷房時冷媒入口管、６は冷房時冷媒出口管である。 Embodiment 5 FIG.
Embodiment 5 of the present invention will be described below with reference to the drawings. FIG. 5 is a side view of a heat exchanger according to Embodiment 5 of the present invention. In the figure, 1 is a front side heat exchanger, 2 is a rear side heat exchanger, 3 is a heat transfer pipe of the heat exchanger, 4 is a fin of the heat exchanger, 5 is a refrigerant inlet pipe during cooling, and 6 is during cooling. It is a refrigerant outlet pipe.

前記各熱交換器１，２は複数枚のフィン４に複数の伝熱管３を垂直に貫通し嵌合させて構成されており、伝熱管３の内部には冷媒を、フィン４間には空気を流通させ、空気を冷却・加熱するものである。前記熱交換器を空気調和機に組み込む場合、空気調和機の大きさを変えることなく高性能化を可能とするために、前記熱交換器を多段に折り曲げて伝熱面積の増加による高性能化を図ったものである。   Each of the heat exchangers 1 and 2 is configured by vertically inserting and fitting a plurality of heat transfer tubes 3 to a plurality of fins 4, a refrigerant inside the heat transfer tubes 3, and air between the fins 4. Is used to cool and heat the air. When incorporating the heat exchanger into an air conditioner, the heat exchanger can be bent in multiple stages to increase performance without changing the size of the air conditioner. Is intended.

前記熱交換器において、冷房時冷媒出口管６を１列部に設けた場合、冷媒が熱交換器出口手前にてドライアウトしてしまうと、その部分を通過する空気は熱交換されず、高温高湿のまま風路へ導かれる。一方ドライアウトしていない部分では空気は冷却除湿され、低温低湿の空気が風路へ導かれる。この両方の空気が風路内にて混合すると、高温高湿の空気は低温低湿の空気に冷やされ、露点温度以下になった場合は凝縮し水滴となり、風路内に付着し、送風機１３により、吹き出し口１０より室内へ前記水滴が吹き出されてしまう。そこで、冷房時冷媒出口管６を２列部に設けることで、冷房時出口手前にてドライアウトしても前列にて熱交換されるため、空気が熱交換されずに通過してしまうことを防止出来、高品質・信頼性を確保することが可能となる。   In the heat exchanger, when the cooling-time refrigerant outlet pipe 6 is provided in one row portion, if the refrigerant is dried out before the heat exchanger outlet, the air passing through the portion is not heat-exchanged, and the temperature is high. It is led to the airway with high humidity. On the other hand, air is cooled and dehumidified in the portion not dried out, and low-temperature and low-humidity air is guided to the air path. When both of these airs are mixed in the air path, the high-temperature and high-humidity air is cooled to low-temperature and low-humidity air. When the dew point temperature or lower is reached, it condenses into water droplets and adheres to the air path. The water droplets are blown out from the air outlet 10 into the room. Therefore, by providing the cooling refrigerant outlet pipe 6 in two rows, heat exchange is performed in the front row even if it is dried out before the cooling outlet, so that air passes without heat exchange. It can be prevented and high quality and reliability can be secured.

この発明に係る空気調和機の熱交換器は、冷房時出口配管を列数の多い部分に設けたことを特徴とする。   The heat exchanger for an air conditioner according to the present invention is characterized in that a cooling outlet pipe is provided in a portion having a large number of rows.

上記構成により、冷房時出口手前にてドライアウトしても前列にて熱交換されるため、空気が熱交換されずに通過することを防止でき、高品質・信頼性を確保することができる。   With the above configuration, heat exchange is performed in the front row even after drying out before the outlet during cooling, so that air can be prevented from passing without heat exchange, and high quality and reliability can be ensured.
