Description

本発明は、ヒートポンプ装置に関する。   The present invention relates to a heat pump device.

ヒートポンプ装置を利用する装置として、空気調和装置が知られている（例えば特許文献１参照）。前記空気調和装置は、室内の空気を排気する小型の換気扇を有する室内機と、導入した空気と冷媒又は熱媒との間で熱交換を行う熱交換器、及び、該熱交換器に外気を供給する室外ファンを有する室外機とを備え、換気扇により排気された空気を熱交換器に導くダクトが設けられている。   An air conditioner is known as a device that uses a heat pump device (see, for example, Patent Document 1). The air conditioner includes an indoor unit having a small ventilation fan that exhausts indoor air, a heat exchanger that exchanges heat between the introduced air and a refrigerant or a heat medium, and external air to the heat exchanger. And an outdoor unit having an outdoor fan to be supplied, and a duct for guiding the air exhausted by the ventilation fan to the heat exchanger is provided.

前記空気調和装置によれば、熱交換器において、ダクトを介して導かれた排気と、室外ファンにより供給された外気とが混合することにより、排気からの熱回収を行い、室内の冷房能力又は暖房能力を増加することができるとされている。   According to the air conditioner, in the heat exchanger, the exhaust led through the duct and the outside air supplied by the outdoor fan are mixed to recover heat from the exhaust, and the indoor cooling capacity or It is said that the heating capacity can be increased.

特開平６−１２３４４３号公報（図１及び図２）JP-A-6-123443 (FIGS. 1 and 2)

ところで、近年、住宅において、シックハウス症候群等への対策のために第３種換気を２４時間行う（以下、２４時間換気という）ことが求められており、２４時間換気用の換気扇やスイッチ等を備えたシステムが設置されている。そこで、前記空気調和装置における換気扇を２４時間換気に利用することが考えられる。   By the way, in recent years, it has been required to perform the third type ventilation for 24 hours (hereinafter referred to as “24 hours ventilation”) in a house in order to cope with sick house syndrome and the like. System is installed. Therefore, it is conceivable to use the ventilation fan in the air conditioner for 24-hour ventilation.

しかしながら、前記空気調和装置において前記換気扇を２４時間換気に利用する場合には、室内の冷房又は暖房を強くするために室外ファンの回転数を大きくすると、室外ファンがダクトの排気口に隣接して設けられていることにより、該ダクトを介して室内の冷気又は暖気が大量に排気されることとなる。その結果、冷房又は暖房効率が悪くなる上に、２４時間換気を一定換気量で行うことができないという不都合がある。   However, when the ventilation fan is used for 24-hour ventilation in the air conditioner, if the rotational speed of the outdoor fan is increased in order to increase the cooling or heating in the room, the outdoor fan is adjacent to the exhaust port of the duct. By being provided, a large amount of cool air or warm air in the room is exhausted through the duct. As a result, there are inconveniences that the cooling or heating efficiency is deteriorated and the 24-hour ventilation cannot be performed with a constant ventilation amount.

そこで、本発明は、かかる不都合を解消して、２４時間換気用のシステムを別個に設置することなく、ヒートポンプ装置の負荷に左右されずに２４時間換気を一定換気量で行うことができ、さらに、排気からの熱回収を行うことができるヒートポンプ装置を提供することを目的とする。   Therefore, the present invention eliminates such inconvenience, and can perform 24-hour ventilation at a constant ventilation without depending on the load of the heat pump device without separately installing a 24-hour ventilation system. An object of the present invention is to provide a heat pump device capable of recovering heat from exhaust.

そこで、前記目的を達成するために、本発明は、空気を導入し、該空気と熱媒との間で熱交換を行う熱交換器と、該熱交換器にそれぞれ隣接して並設され、該熱交換器に空気を供給する第１のファン及び第２のファンと、該熱交換器、第１のファン及び第２のファンを収容する単一の筐体とを備えるヒートポンプ装置において、該熱交換器に外気を供給する第１のファンとは独立して、第２のファンの空気取込口及び部屋の壁に設けられた換気口を接続し、部屋の排気を第２のファンに供給するダクトと、第２のファンの回転数を一定に保持する回転数保持手段とを備え、第２のファンにより、第３種換気を常時一定換気量で行うことを特徴とする。 Therefore, in order to achieve the above-mentioned object, the present invention introduces air, heat exchangers for exchanging heat between the air and the heat medium, and juxtaposed adjacent to the heat exchangers, A heat pump apparatus comprising: a first fan and a second fan that supply air to the heat exchanger; and a single housing that houses the heat exchanger, the first fan, and the second fan, Independently of the first fan that supplies the outside air to the heat exchanger, the air intake port of the second fan and the ventilation port provided on the wall of the room are connected, and the exhaust of the room is connected to the second fan. A duct to be supplied and a rotation speed holding means for holding the rotation speed of the second fan constant are provided, and the third type ventilation is always performed with a constant ventilation amount by the second fan.

本発明のヒートポンプ装置において、熱交換器、第１のファン及び第２のファンは、単一の筐体内に収容されている。第２のファンは、常時作動し、部屋の排気を、換気口及びダクトを介して空気取込口から取り込み、熱交換器に供給する。このとき、第２のファンは、その回転数が回転数保持手段により一定に保持されているので、第２のファンによる熱交換器への空気供給量、すなわち、第２のファンによる第３種換気の換気量は常時一定となる。一方、第１のファンは、取り込んだ外気を熱交換器に供給するものの、ダクトから独立しているため、ダクトを介して部屋の排気を取り込むことはなく、第１のファンの運転状態が部屋の換気量に影響を与えることがない。 In the heat pump device of the present invention, the heat exchanger, the first fan, and the second fan are accommodated in a single casing. The second fan always operates and takes in the exhaust of the room from the air intake through the ventilation opening and the duct and supplies it to the heat exchanger. At this time, since the rotation speed of the second fan is kept constant by the rotation speed holding means, the amount of air supplied to the heat exchanger by the second fan, that is, the third type by the second fan. The amount of ventilation is always constant. On the other hand, although the first fan supplies the outside air taken in to the heat exchanger, it is independent of the duct, so the exhaust of the room is not taken in through the duct, and the operating state of the first fan is the room. Does not affect the ventilation volume.

したがって、本発明のヒートポンプ装置によれば、運転負荷の大小によらず、２４時間換気を一定換気量で行うことができる。また、本発明のヒートポンプ装置によれば、第２のファンを２４時間換気に利用することができるので、２４時間換気用のシステムを別個に設置する必要がない。   Therefore, according to the heat pump device of the present invention, ventilation for 24 hours can be performed with a constant ventilation amount regardless of the magnitude of the operation load. In addition, according to the heat pump device of the present invention, the second fan can be used for 24-hour ventilation, so there is no need to separately install a 24-hour ventilation system.

また、本発明のヒートポンプ装置によれば、熱交換器において、第２のファン及びダクトを介して導かれた部屋の排気を用いることにより、該排気からの熱回収を行うことができる。   In addition, according to the heat pump device of the present invention, by using the exhaust of the room led through the second fan and the duct in the heat exchanger, heat recovery from the exhaust can be performed.

また、本発明のヒートポンプ装置は、前記筐体は、第１のファンの空気取込口及び第２のファンの空気取込口が連続してなる共通空気取込口を備え、該共通空気取込口を分画して第２のファンの空気取込口を第１のファンの空気取込口から独立させるアダプタを備えることが好ましい。前記構成では、第１のファン及び第２のファンは、前記共通空気取込口から共通して空気を取り込むようになっている。前記構成によれば、従来から用いられている前記共通空気取込口を備える室外機に前記アダプタを取り付けることでその利用が可能となる上に、前記共通空気取込口の大きさや形状が前記室外機の機種によって異なる場合であっても、該アダプタの大きさを変更することにより第２のファンの空気取込量を調整し、所望の換気量にて２４時間換気を行うことができる。 Further, the heat pump apparatus of the present invention, wherein the housing is provided with a common air inlet for air inlet of the first fan and the air inlet of the second fan is continuously, the common air intake it is preferred that the air inlet of the second fan fractionating the plug mouth partial comprises adapters for independent air inlet of the first fan. In the above configuration, the first fan and the second fan take in air from the common air intake port in common. According to the configuration, the adapter can be used by attaching the adapter to an outdoor unit provided with the common air intake port that has been conventionally used, and the size and shape of the common air intake port are Even if it is different depending on the model of the outdoor unit, the air intake amount of the second fan can be adjusted by changing the size of the adapter, and ventilation can be performed for 24 hours with a desired ventilation amount.

また、本発明のヒートポンプ装置は、前記熱交換器で熱交換された熱媒の熱を、前記部屋の内部に設けられた暖房負荷に供給する他の熱交換器を備え、第２のファンにより、該暖房負荷で暖房が行われた該部屋の空気を取り込むことを特徴とすることが好ましい。本発明のヒートポンプ装置によれば、第２のファンによる第３種換気の換気量は常に一定であるので、運転負荷が大きい場合であっても、前記暖房負荷で暖められた部屋の空気が大量に排気されて暖房効率が悪くなることを防ぐことができる。   In addition, the heat pump device of the present invention includes another heat exchanger that supplies heat of the heat medium exchanged by the heat exchanger to a heating load provided in the room, and is provided by a second fan. It is preferable that air in the room heated by the heating load is taken in. According to the heat pump device of the present invention, since the amount of ventilation of the third type ventilation by the second fan is always constant, even if the operation load is large, the air in the room heated by the heating load is large. It is possible to prevent the heating efficiency from being deteriorated due to exhaust.

As shown in FIG. 2, the adapter 12 includes a connecting cylindrical portion 12a and a separation plate 12b. With the above configuration, the common air intake 8 is divided by the adapter 12 to become the air intake 8 a of the first fan 5 and the air intake 8 b of the second fan 9. In addition, with the above configuration, the duct 11 connects the air intake port 8b of the second fan 9 and the first ventilation port 10 independently of the first fan 5, so that the first fan 5 prevents the exhaust of the room 2 from being taken in.

第１のファン５及び第２のファン９は、第１の熱交換器４の空気取入側に設けられ、いずれもクロスフローファンである。第１のファン５は、第２のファン９と比較して、大きな送風能力すなわち空気取込能力を備えている。   The first fan 5 and the second fan 9 are provided on the air intake side of the first heat exchanger 4, and both are cross flow fans. The first fan 5 has a large air blowing capacity, that is, an air intake capacity, as compared with the second fan 9.

第２のファン９は、その回転数を一定に保持する回転数保持手段としてのディップスイッチ９ａを備えており、２４時間一定回転で運転が可能となっている。第２のファン９は、ディップスイッチ９ａを備えることにより、第３種換気を常時一定換気量で行うことができるとともに、部屋２の大きさ等に応じて、換気量を容易に調整できるようになっている。   The second fan 9 includes a dip switch 9a as a rotation speed holding means for holding the rotation speed constant, and can be operated at a constant rotation for 24 hours. The second fan 9 is provided with the dip switch 9a so that the third type ventilation can always be performed with a constant ventilation amount, and the ventilation amount can be easily adjusted according to the size of the room 2 and the like. It has become.

第１の熱交換器４には、第１の熱媒還流管１３の両端部が接続されている。第１の熱媒還流管１３は、その途中に、上流側から順に、圧縮器１４と、第１の熱媒と第２の熱媒との間で熱交換を行う第２の熱交換器７と、膨張弁１５とを備えている。   Both ends of the first heat medium reflux pipe 13 are connected to the first heat exchanger 4. In the middle of the first heat medium reflux pipe 13, the second heat exchanger 7 that performs heat exchange between the compressor 14 and the first heat medium and the second heat medium in order from the upstream side. And an expansion valve 15.

一方、部屋２の床６には、床下の空気と部屋２の内部の空気とを流通させるための開口部１６ａ，１６ｂが設けられている。床下には、第２の熱媒体と部屋２の空気との間で熱交換を行う第１の放熱器１７が設けられ、該第１の放熱器１７には第２の熱媒還流管１８の両端部が接続されている。第１の開口部１６ａは、第１の放熱器１７の上方に設けられ、第２の開口部１６ｂは、第１の開口部１６ａから離れた壁際に設けられている。   On the other hand, the floor 6 of the room 2 is provided with openings 16a and 16b for circulating the air under the floor and the air inside the room 2. Under the floor, a first heat radiator 17 is provided for exchanging heat between the second heat medium and the air in the room 2. The first heat radiator 17 includes a second heat medium return pipe 18. Both ends are connected. The first opening portion 16a is provided above the first heat radiator 17, and the second opening portion 16b is provided near the wall away from the first opening portion 16a.

第２の熱媒還流管１８は、その途中に、上流側から順に、ポンプ１９と、第２の熱交換器７とを備えている。また、第２の熱媒還流管１８には、ポンプ１９の上流側で分岐するとともに、第２の熱交換器７の下流側で合流する分岐管２０が接続されている。分岐管２０は、その途中に、第２の熱媒と部屋の壁に設けられた第２の換気口２１から取り込んだ外気との間で熱交換を行う第２の放熱器２２を備えている。   The second heat medium reflux pipe 18 is provided with a pump 19 and a second heat exchanger 7 in the order from the upstream side. Further, a branch pipe 20 that branches on the upstream side of the pump 19 and joins on the downstream side of the second heat exchanger 7 is connected to the second heat medium reflux pipe 18. The branch pipe 20 includes a second radiator 22 that exchanges heat between the second heat medium and the outside air taken in from the second ventilation port 21 provided on the wall of the room. .

次に、本実施形態のヒートポンプ装置１の作動について説明する。まず、第１のファン５が、空気取込口８ａから外気を取り込み、第１の熱交換器４に供給する。一方、第２のファン９が、第１の換気口１０及びダクト１１を介して部屋２の排気を空気取込口８ｂから取り込み、第１の熱交換器４に供給する。第１の熱交換器４は、外気及び部屋２の排気と第１の熱媒との間で熱交換を行うことにより、第１の熱媒で採熱を行う。   Next, the operation of the heat pump device 1 of the present embodiment will be described. First, the first fan 5 takes in outside air from the air intake 8 a and supplies it to the first heat exchanger 4. On the other hand, the second fan 9 takes in the exhaust of the room 2 from the air intake 8 b through the first ventilation port 10 and the duct 11 and supplies it to the first heat exchanger 4. The first heat exchanger 4 performs heat exchange with the first heat medium by exchanging heat between the outside air and the exhaust of the room 2 and the first heat medium.

採熱した第１の熱媒は、第１の熱媒還流管１３を流通し、圧縮器１４で圧縮されることにより温度が上昇し、第２の熱交換器７に導入される。第２の熱交換器７は、温度上昇した第１の熱媒と第２の熱媒との間で熱交換を行うことにより、第２の熱媒で採熱を行う。第２の熱交換器７で熱交換された第１の熱媒は、膨張弁１５により膨張された後、第１の熱交換器４に還流される。   The collected first heat medium flows through the first heat medium recirculation pipe 13 and is compressed by the compressor 14, so that the temperature rises and is introduced into the second heat exchanger 7. The second heat exchanger 7 collects heat with the second heat medium by exchanging heat between the first heat medium and the second heat medium whose temperature has increased. The first heat medium heat-exchanged by the second heat exchanger 7 is expanded by the expansion valve 15 and then returned to the first heat exchanger 4.

採熱した第２の熱媒は、ポンプ１９により、第２の熱媒還流管１８を流通し、第１の放熱器１７に導入され、第２の熱交換器７に還流される。第２の熱媒が第２の熱媒還流管１８を流通することにより、床下の空気を暖めることができる。また、第２の熱媒還流管１８を流通する第２の熱媒の一部は、分岐管２０を流通し、第２の放熱器２２に導入される。   The collected second heat medium is circulated through the second heat medium reflux pipe 18 by the pump 19, introduced into the first radiator 17, and refluxed to the second heat exchanger 7. When the second heat medium flows through the second heat medium return pipe 18, the air under the floor can be warmed. A part of the second heat medium flowing through the second heat medium reflux pipe 18 flows through the branch pipe 20 and is introduced into the second radiator 22.

第１の放熱器１７は、第１の開口部１６ａを介して、第２の熱媒と部屋２の内部の空気との間で熱交換を行うことにより、部屋２の内部の空気を暖める。また、第２の放熱器２２は、第２の熱媒と、第２の換気口２１から取り込まれた外気との間で熱交換を行うことにより、取り込まれた外気を暖める。取り込まれ暖められた外気は、部屋２の内部に供給される。この結果、部屋２の内部に空気の流れが生じ、部屋２の空気の一部が第２の開口部１６ｂを介して床下へ流通される。   The first heat radiator 17 warms the air inside the room 2 by exchanging heat between the second heat medium and the air inside the room 2 through the first opening 16a. The second radiator 22 warms the taken-in outside air by exchanging heat between the second heat medium and the outside air taken in from the second ventilation port 21. The outside air taken in and warmed is supplied to the inside of the room 2. As a result, an air flow is generated inside the room 2, and a part of the air in the room 2 is circulated under the floor through the second opening 16b.

以上のようにして、本実施形態のヒートポンプ装置１によれば、外気及び部屋２の排気から第１，第２の熱交換器４，７を介して採熱した熱を、第１，第２の放熱器１７，２２を介して部屋２の内部に供給することにより、部屋２の内部を暖房することができる。   As described above, according to the heat pump device 1 of the present embodiment, the heat collected from the outside air and the exhaust of the room 2 via the first and second heat exchangers 4 and 7 is first and second. The interior of the room 2 can be heated by supplying the interior of the room 2 via the radiators 17 and 22.

このとき、本実施形態のヒートポンプ装置１では、第２のファン９は、常時作動し、その回転数がディップスイッチ９ａにより一定に保持されていることにより、第２のファン９による第１の熱交換器４への空気供給量、すなわち、第２のファン９による第３種換気の換気量は常時一定となる。一方、第１のファン５は、取り込んだ外気を第１の熱交換器４に供給するものの、ダクト１１からは独立しているため、ダクト１１を介して部屋２の排気を取り込むことはなく、第１のファン５の運転状態が部屋２の換気量に影響を与えることがない。   At this time, in the heat pump device 1 of the present embodiment, the second fan 9 always operates and the rotation speed thereof is kept constant by the dip switch 9a, so that the first heat generated by the second fan 9 is maintained. The amount of air supplied to the exchanger 4, that is, the amount of ventilation of the third type ventilation by the second fan 9 is always constant. On the other hand, the first fan 5 supplies the taken outside air to the first heat exchanger 4, but is independent of the duct 11, so it does not take in the exhaust of the room 2 through the duct 11, The operating state of the first fan 5 does not affect the ventilation amount of the room 2.

したがって、本実施形態のヒートポンプ装置１によれば、運転負荷の大小によらず、２４時間換気を一定換気量で行うことができる。また、本実施形態のヒートポンプ装置１によれば、第２のファン９を２４時間換気に利用することができるので、２４時間換気用のシステムを別個に設置する必要がない。   Therefore, according to the heat pump device 1 of the present embodiment, the 24-hour ventilation can be performed with a constant ventilation amount regardless of the operating load. Moreover, according to the heat pump apparatus 1 of this embodiment, since the 2nd fan 9 can be utilized for 24 hours ventilation, it is not necessary to install the system for 24 hours ventilation separately.

また、本発明のヒートポンプ装置１によれば、第２のファン９による第３種換気の換気量は常に一定であるので、運転負荷が大きい場合に、暖められた部屋２の空気が大量に排気されて暖房効率が悪くなることを防ぐことができる。   Further, according to the heat pump apparatus 1 of the present invention, the amount of ventilation of the third type ventilation by the second fan 9 is always constant, so that a large amount of air in the warmed room 2 is exhausted when the operation load is large. It is possible to prevent the heating efficiency from being deteriorated.

また、本実施形態のヒートポンプ装置１によれば、第１の熱交換器４において、第２のファン９及びダクト１１を介して導かれた部屋２の排気を用いることにより、該排気からの熱回収を行うことができる。   Moreover, according to the heat pump apparatus 1 of this embodiment, in the 1st heat exchanger 4, by using the exhaust_gas | exhaustion of the room 2 guided through the 2nd fan 9 and the duct 11, the heat from this exhaust_gas | exhaustion is used. Recovery can be performed.

また、通常、寒冷地では、外気温の低下により第１の熱交換器４に霜が付着するため、該霜を除去するためにデフロスト運転を行う必要があるが、本実施形態のヒートポンプ装置１では、前記排気から回収した熱により、該霜を除去することができる。したがって、本実施形態のヒートポンプ装置１によれば、デフロスト運転の回数を減らすことができ、暖房効率を向上させることができる。   In general, in cold districts, frost adheres to the first heat exchanger 4 due to a decrease in the outside air temperature. Therefore, it is necessary to perform a defrost operation in order to remove the frost, but the heat pump device 1 of the present embodiment. Then, the frost can be removed by the heat recovered from the exhaust. Therefore, according to the heat pump apparatus 1 of this embodiment, the frequency | count of a defrost driving | operation can be reduced and heating efficiency can be improved.
