Moreover, the 2nd upper piping 51 of the hot water storage tank 41 is connected to faucets and bath terminals (not shown), such as a kitchen or a washroom.
次に、本発明の第１の実施の形態におけるヒートポンプ給湯装置の貯湯運転動作について説明する。 Next, the hot water storage operation of the heat pump hot water supply apparatus in the first embodiment of the present invention will be described.
使用者が蛇口を開くと第二上部配管５１から出湯され、貯湯タンク４１の残湯量が少なくなると、ヒートポンプサイクル３０が運転を開始する。 When the user opens the faucet, the hot water is discharged from the second upper pipe 51, and when the remaining hot water amount in the hot water storage tank 41 decreases, the heat pump cycle 30 starts operation.
圧縮機３１で圧縮された冷媒は、給湯用熱交換器３２で放熱し、膨張弁３３で減圧された後、蒸発器３４にて吸熱し、ガス状態で圧縮機３１に吸入される。ファン３５は、圧縮機３１の運転状態に応じた回転数に設定される。 The refrigerant compressed by the compressor 31 radiates heat by the hot water supply heat exchanger 32, is depressurized by the expansion valve 33, absorbs heat by the evaporator 34, and is sucked into the compressor 31 in a gas state. The fan 35 is set to a rotational speed corresponding to the operating state of the compressor 31.
循環ポンプ４７により貯湯タンク４１からの水は、貯湯タンク４１の第二底部配管４６を通り、給湯用熱交換器３２の水用配管３２Ａに導かれ、高温の湯に加熱され、三方弁４９を介し、貯湯タンク４１に流入する。三方弁４９において、貯湯タンク４１の第一上部配管４８に接続するか、貯湯タンク４１の第三底部配管５０に接続するかの判断は、給湯用熱交換器３２の水用配管３２Ａの出口側に設置している出湯温度センサ３２Ｂの温度によって行う。 Water from the hot water storage tank 41 is passed through the second bottom piping 46 of the hot water storage tank 41 by the circulation pump 47 and led to the water piping 32A of the hot water supply heat exchanger 32 and heated to high temperature hot water.

図２（ａ）（ｂ）において、貯湯タンク４１の胴部に真空断熱材Ａ４２を、上部および下部にグラスウール断熱材４３を用いる構成とした。４４はテープであり、真空断熱材Ａ４２と貯湯タンク４１の間の空気の流れを遮断するように貼り付けている。４２Ａは、真空断熱材Ａ４２に設けた凹部で、この凹部により貯湯タンク４１に真空断熱材Ａ４２を巻いても一部密着せず、貯湯タンク４１と真空断熱材Ａ４２の間に隙間ができる。 2A and 2B, a vacuum heat insulating material A42 is used for the body portion of the hot water storage tank 41, and a glass wool heat insulating material 43 is used for the upper and lower portions. Reference numeral 44 denotes a tape, which is attached so as to block the air flow between the vacuum heat insulating material A42 and the hot water storage tank 41. 42 </ b> A is a recess provided in the vacuum heat insulating material A <b> 42, and even if the vacuum heat insulating material A <b> 42 is wound around the hot water storage tank 41 by this recess, a part of the vacuum heat insulating material A <b> 42 does not adhere to it.
以上のように本実施の形態のヒートポンプ給湯装置は、貯湯タンクの断熱材として真空断熱材を使用し、貯湯タンクに真空断熱材を貼り付ける際、真空断熱材に凹部を設けているため、貯湯タンクに一部密着させずに貼り付けることが可能となり、真空断熱材の外袋からの熱伝導を最低限にでき、かつ真空断熱材の性能を最大限にできる貼り付け方としているため、所望の断熱性能が得られ小型化ができ、湯切れを防止できる。 As described above, the heat pump water heater of the present embodiment uses a vacuum heat insulating material as a heat insulating material for a hot water storage tank, and when the vacuum heat insulating material is attached to the hot water storage tank, a recess is provided in the vacuum heat insulating material. It is possible to apply without sticking partly to the tank, the heat conduction from the outer bag of the vacuum heat insulating material can be minimized, and the method of attaching can maximize the performance of the vacuum heat insulating material. Insulation performance is obtained, miniaturization is possible, and hot water can be prevented from running out.
また、本実施の形態では冷媒として二酸化炭素を用いた場合で説明したが、冷媒としてＲ４１０Ａ冷媒やＨＣ冷媒などのその他の冷媒を用いてもよい。 In the present embodiment, the case where carbon dioxide is used as the refrigerant has been described. However, other refrigerants such as R410A refrigerant and HC refrigerant may be used as the refrigerant.
また、本実施の形態では、ヒートポンプサイクル１０を備えたヒートポンプ給湯装置を用いて説明したが、２つ以上のヒートポンプサイクルを用いてもよい。 Moreover, although this Embodiment demonstrated using the heat pump hot-water supply apparatus provided with the heat pump cycle 10, you may use two or more heat pump cycles.
なお、貯湯タンク４１の上部および下部をグラスウール断熱材４３で説明したが、発泡スチロール等の断熱材を使用してもよい。 In addition, although the upper part and lower part of the hot water storage tank 41 were demonstrated with the glass wool heat insulating material 43, you may use heat insulating materials, such as a polystyrene foam.
（実施の形態２）

(Embodiment 2)
Fig.3 (a) is a schematic front view of the hot water storage tank of the heat pump hot-water supply apparatus in the 2nd Embodiment of this invention, FIG.3 (b) is sectional AA figure.
図３（ａ）（ｂ）において、図３（ａ）の左図は、貯湯タンク４１に両面テープ４２Ｂを貼り付けた図である。図３（ａ）の右図は、さらに断熱材を貼り付けた図であり、貯湯タンク４１の胴部に真空断熱材Ａ４２を、上部および下部にグラスウール断熱材４３を用いる構成とした。貯湯タンク４１にを貼り付ける際、両面テープ４２Ｂを用いて貼り付けている。従って、貯湯タンク４１と真空断熱材Ａ４２との間に隙間を設けることが可能となると共に、真空断熱材Ａ４２と貯湯タンク４１の間の高温の空気が外部に流れることが防止できる。さらに、その上に実施の形態１で示したようにテープ４４（図示せず）で貼り付けると効果が増す。 3A and 3B, the left diagram in FIG. 3A is a diagram in which the double-sided tape 42 </ b> B is attached to the hot water storage tank 41. The right figure of Fig.3 (a) is the figure which further affixed the heat insulating material, and set it as the structure which uses the vacuum heat insulating material A42 for the trunk | drum of the hot water storage tank 41, and the glass wool heat insulating material 43 for the upper part and the lower part. When affixing to the hot water storage tank 41, it is affixed using the double-sided tape 42B. Therefore, it is possible to provide a gap between the hot water storage tank 41 and the vacuum heat insulating material A42 and to prevent high-temperature air between the vacuum heat insulating material A42 and the hot water storage tank 41 from flowing to the outside. Furthermore, if the tape 44 (not shown) is attached thereon as shown in the first embodiment, the effect is increased.
４２Ｃは、真空断熱材Ａ４２とは別に設けられた真空断熱材であり、真空断熱材Ａ４２に対して開閉自在な構成となっている。これは、貯湯タンク４１の側面に備え付けた残湯サーミスターのメンテナンスを行い易くするためのものであり、メンテナンス時には真空断熱材４２Ｃを開いて残湯サーミスターのメンテナンスを行うと共に、メンテナンス時以外には真空断熱材４２Ｃを閉じることにより、真空断熱材Ａ４２により覆いきれていない貯湯タンク４１の表面部分を覆うようになっている。なお、真空断熱材４２Ｃは図３（ｂ）に示されているように、真空断熱材Ａ４２により覆いきれていない貯湯タンク４１の露呈部分よりも大きめの寸法とし、露呈部分の上に重なるように設計されていることから、真空断熱材４２Ｃの一部分が真空断熱材Ａ４２に対して前方に出る構成となる。これは、真空断熱材４２Ｃの一部分が前方に出ることにより、真空断熱材４２Ｃが開閉しやすくなるだけでなく、貯湯タンク４１と真空断熱材４２Ｃの間にわずかな凹部が形成されることから、外袋からの伝導熱量を緩和できるものである。 42C is a vacuum heat insulating material provided separately from the vacuum heat insulating material A42, and can be opened and closed with respect to the vacuum heat insulating material A42. This is for facilitating maintenance of the remaining hot water thermistor provided on the side surface of the hot water storage tank 41. During the maintenance, the vacuum heat insulating material 42C is opened to perform maintenance of the remaining hot water thermistor. By closing the vacuum heat insulating material 42C, the surface portion of the hot water storage tank 41 that is not covered by the vacuum heat insulating material A42 is covered. As shown in FIG. 3B, the vacuum heat insulating material 42C has a size larger than the exposed portion of the hot water storage tank 41 that is not covered by the vacuum heat insulating material A42, and overlaps the exposed portion. Since it is designed, a part of the vacuum heat insulating material 42C comes to the front with respect to the vacuum heat insulating material A42. This is because not only the vacuum heat insulating material 42C is easily opened and closed by a part of the vacuum heat insulating material 42C coming forward, but a slight recess is formed between the hot water storage tank 41 and the vacuum heat insulating material 42C. The amount of conduction heat from the outer bag can be relaxed.
また、真空断熱材Ａ４２には凹部４２Ａ（図示せず）を設けており、貯湯タンク４１と真空断熱材Ａ４２は一部密着していない。また、真空断熱材Ｂ４２Ｃは、左側はテープで貼り付け（図示せず）、真空断熱材Ａ４２と重なっている右側はマジックテープ（登録商標）（図示せず）等により貼り付け、断熱性とメンテナンス性を考えた仕様としている。 Further, the vacuum heat insulating material A42 is provided with a recess 42A (not shown), and the hot water storage tank 41 and the vacuum heat insulating material A42 are not in close contact with each other. Further, the vacuum heat insulating material B42C is attached with tape on the left side (not shown), and the right side overlapping with the vacuum heat insulating material A42 is attached with Velcro (registered trademark) (not shown), etc. It is a specification that considers sex.
以上のように本実施の形態のヒートポンプ給湯装置は、貯湯タンクの断熱材として真空断熱材を使用し、貯湯タンクに真空断熱材を貼り付ける際、真空断熱材Ａ４２と貯湯タンク４１の間の高温の空気が外部に流れない様に貼り付ける。従って、真空断熱材と貯湯タンクの間の高温の空気が外部に流れることを防止でき、対流による放熱が防止でき、所望の断熱性能が得られ小型化ができ、湯切れを防止できる。 As described above, the heat pump water heater of the present embodiment uses the vacuum heat insulating material as the heat insulating material for the hot water storage tank, and the high temperature between the vacuum heat insulating material A42 and the hot water storage tank 41 when the vacuum heat insulating material is attached to the hot water storage tank. Paste so that no air flows outside. Accordingly, it is possible to prevent high-temperature air between the vacuum heat insulating material and the hot water storage tank from flowing to the outside, to prevent heat dissipation by convection, to obtain a desired heat insulating performance, to reduce the size, and to prevent hot water from running out.

図４（ａ）は、本発明の第３の実施の形態におけるヒートポンプ給湯装置の貯湯タンクの概略正面図、図４（ｂ）は断面ＡＡ図である。
(Embodiment 3)
FIG. 4A is a schematic front view of a hot water storage tank of a heat pump hot water supply apparatus according to the third embodiment of the present invention, and FIG.
図４（ａ）（ｂ）において、図４（ａ）の左図は、貯湯タンク４１に両面テープ４２Ｂを貼り付けた図である。図４（ａ）の右図は、さらに断熱材を貼り付けた図であり、貯湯タンク４１の胴部に真空断熱材Ａ４２を、上部および下部にグラスウール断熱材４３を用いる構成とした。貯湯タンク４１にを貼り付ける際、両面テープ４２Ｂを用いて貼り付けている。従って、貯湯タンク４１と真空断熱材Ａ４２との間に隙間を設けることが可能となると共に、真空断熱材Ａ４２と貯湯タンク４１の間の高温の空気が外部に流れることが防止できる。さらに、その上に実施の形態１で示したようにテープ４４（図示せず）で貼り付けると効果が増す。 4 (a) and 4 (b), the left figure of FIG. 4 (a) is the figure which stuck the double-sided tape 42B to the hot water storage tank 41. FIG. The right diagram in FIG. 4A is a diagram in which a heat insulating material is further pasted, and the vacuum heat insulating material A42 is used for the body portion of the hot water storage tank 41, and the glass wool heat insulating material 43 is used for the upper and lower portions. When affixing to the hot water storage tank 41, it is affixed using the double-sided tape 42B. Therefore, it is possible to provide a gap between the hot water storage tank 41 and the vacuum heat insulating material A42 and to prevent high-temperature air between the vacuum heat insulating material A42 and the hot water storage tank 41 from flowing to the outside. Furthermore, if the tape 44 (not shown) is attached thereon as shown in the first embodiment, the effect is increased.
４２Ｄは、真空断熱材Ａ４２とは別に設けられた真空断熱材であり、真空断熱材Ａ４２に対して開閉自在な構成となっている。これは、貯湯タンク４１の側面に備え付けた残湯サーミスターのメンテナンスを行い易くするためのものであり、メンテナンス時には真空断熱材４２Ｄを開いて残湯サーミスターのメンテナンスを行うと共に、メンテナンス時以外には真空断熱材４２Ｄを閉じることにより、真空断熱材Ａ４２により覆いきれていない貯湯タンク４１の表面部分を覆うようになっている。なお、真空断熱材４２Ｄは図４（ｂ）に示されているように、真空断熱材Ａ４２により覆いきれていない貯湯タンク４１の露呈部分よりも大きめの寸法とし、露呈部分の上に重なるように設計されていることから、真空断熱材４２Ｄの一部分が真空断熱材Ａ４２に対して前方に出る構成となる。これは、真空断熱材４２Ｄの一部分が前方に出ることにより、真空断熱材４２Ｄが開閉しやすくなるだけでなく、貯湯タンク４１と真空断熱材４２Ｄの間にわずかな凹部が形成されることから、外袋からの伝導熱量を緩和できるものである。また、真空断熱材４２Ｄは、上下２分割としているので、一層容易にメンテナンスが行える。 42D is a vacuum heat insulating material provided separately from the vacuum heat insulating material A42, and is configured to be openable and closable with respect to the vacuum heat insulating material A42. This is for facilitating maintenance of the remaining hot water thermistor provided on the side surface of the hot water storage tank 41. During maintenance, the vacuum heat insulating material 42D is opened to perform maintenance of the remaining hot water thermistor. Is configured to cover the surface portion of the hot water storage tank 41 that is not covered by the vacuum heat insulating material A42 by closing the vacuum heat insulating material 42D. As shown in FIG. 4B, the vacuum heat insulating material 42D has a size larger than the exposed portion of the hot water storage tank 41 that is not covered by the vacuum heat insulating material A42, and overlaps the exposed portion. Since it is designed, a part of the vacuum heat insulating material 42D comes to the front with respect to the vacuum heat insulating material A42. This is because not only the vacuum heat insulating material 42D is easily opened and closed by a part of the vacuum heat insulating material 42D coming forward, but a slight recess is formed between the hot water storage tank 41 and the vacuum heat insulating material 42D. The amount of conduction heat from the outer bag can be relaxed. Further, since the vacuum heat insulating material 42D is divided into upper and lower parts, maintenance can be performed more easily.
また、真空断熱材Ａ４２には凹部４２Ａ（図示せず）を設けており、貯湯タンク４１と真空断熱材Ａ４２は一部密着していない。また、真空断熱材Ｃ４２Ｄは、左右ともマジックテープ（登録商標）（図示せず）等により貼り付け、さらに断熱性とメンテナンス性を考えた仕様としている。 Further, the vacuum heat insulating material A42 is provided with a recess 42A (not shown), and the hot water storage tank 41 and the vacuum heat insulating material A42 are not in close contact with each other. Further, the vacuum heat insulating material C42D is attached to both the left and right sides with Velcro (registered trademark) (not shown) or the like, and further has a specification that takes heat insulation and maintenance into consideration.
以上のように本実施の形態のヒートポンプ給湯装置は、貯湯タンクの断熱材として真空断熱材を使用し、貯湯タンクに真空断熱材を貼り付ける際、真空断熱材Ａ４２と貯湯タンク４１の間の高温の空気が外部に流れない様に貼り付ける。従って、真空断熱材と貯湯タンクの間の高温の空気が外部に流れることを防止でき、対流による放熱が防止でき、所望の断熱性能が得られ小型化ができ、湯切れを防止できる。 As described above, the heat pump water heater of the present embodiment uses the vacuum heat insulating material as the heat insulating material for the hot water storage tank, and the high temperature between the vacuum heat insulating material A42 and the hot water storage tank 41 when the vacuum heat insulating material is attached to the hot water storage tank. Paste so that no air flows outside. Accordingly, it is possible to prevent high-temperature air between the vacuum heat insulating material and the hot water storage tank from flowing to the outside, to prevent heat dissipation by convection, to obtain a desired heat insulating performance, to reduce the size, and to prevent hot water from running out.
また、本実施の形態では冷媒として二酸化炭素を用いた場合で説明したが、冷媒としてＲ４１０Ａ冷媒やＨＣ冷媒などのその他の冷媒を用いてもよい。 In the present embodiment, the case where carbon dioxide is used as the refrigerant has been described. However, other refrigerants such as R410A refrigerant and HC refrigerant may be used as the refrigerant.
また、本実施の形態では、ヒートポンプサイクル１０を備えたヒートポンプ給湯装置を用いて説明したが、２つ以上のヒートポンプサイクルを用いてもよい。 Moreover, although this Embodiment demonstrated using the heat pump hot-water supply apparatus provided with the heat pump cycle 10, you may use two or more heat pump cycles.
なお、貯湯タンク４１の上部および下部をグラスウール断熱材４３で説明したが、発泡スチロール等の断熱材を使用してもよい。 In addition, although the upper part and lower part of the hot water storage tank 41 were demonstrated with the glass wool heat insulating material 43, you may use heat insulating materials, such as a polystyrene foam.
なお、残湯サーミスター等のメンテナンス用に真空断熱材４２Ｄは上下２分割として説
明したが、さらに分割してもよい。また、サーミスタごとに対応してメンテナンスが可能となるための開閉可能な扉を真空断熱材Ａ４２に対して設け、扉を開けてメンテナンスできる仕様としてもよい。
Although the vacuum heat insulating material 42D has been described as being divided into upper and lower parts for maintenance of a remaining hot water thermistor or the like, it may be further divided. Moreover, it is good also as a specification which can provide the door which can be opened and closed for maintenance corresponding to every thermistor with respect to the vacuum heat insulating material A42, and can open and maintain a door.
また、貯湯タンクに真空断熱材を貼り付ける手段として両面テープ、マジックテープ（登録商標）で説明したが、所定の目的が達せられれば、その他の方法を用いてもよい。 Moreover, although the double-sided tape and Velcro (registered trademark) have been described as means for attaching the vacuum heat insulating material to the hot water storage tank, other methods may be used as long as a predetermined purpose is achieved.
以上のように、本発明にかかるヒートポンプ給湯装置は、貯湯タンクの断熱材として真空断熱材を使用し、前記貯湯タンクに前記真空断熱材を貼り付ける際、一部密着させずに貼り付けているので、真空断熱材の外袋からの熱伝導を最低限にでき、かつ真空断熱材の性能を最大限にできる貼り付け方としているため、所望の断熱性能が得られ小型化ができ、湯切れを防止できるので、温水を貯湯し、その温水を利用した暖房等の性能向上の用途にも適用できる。 As described above, the heat pump hot water supply apparatus according to the present invention uses a vacuum heat insulating material as a heat insulating material for a hot water storage tank, and affixes the vacuum heat insulating material to the hot water storage tank without adhering partly. Therefore, the heat conduction from the outer bag of the vacuum heat insulating material can be minimized, and the application method is to maximize the performance of the vacuum heat insulating material. Since it can be prevented, it can also be applied to performance improvement such as warm water storage and heating using the hot water.
