本発明に係るヒートポンプ式空気調和装置の実施例を添付図面に基づいて詳細に説明する。
ケーシング1内には、外気入口2aから被空調室(図示省略)への給気口2bに至る給気流路2と、被空調室からの還気を導入する還気口3aから外部への排気口3bに至る還気流路3とが仕切り板1aによって区画されていて、給気流路2と還気流路3との間には、これら2つの流路を跨ぐ全熱交換器4を備えている。
An embodiment of a heat pump type air conditioner according to the present invention will be described in detail with reference to the accompanying drawings.
In the casing 1, the supply air flow path 2 extending from the outside air inlet 2 a to the air supply port 2 b to the air-conditioned room (not shown) and the exhaust from the return air port 3 a for introducing the return air from the air-conditioned room to the outside. The return air flow path 3 reaching the port 3b is partitioned by a partition plate 1a, and a total heat exchanger 4 straddling the two flow paths is provided between the supply air flow path 2 and the return air flow path 3. .

前記給気流路2には、外気入口2a側から給気口2bに向かって順に、フィルタ5、前記全熱交換器4、加湿器6、給気側熱交換器7、送風機8を設けてあり、前記還気流路3には、還気口3aから排気口3bに向かって順に、フィルタ9、前記全熱交換器4、還気側熱交換器10、送風機11を設けてある。   The air supply flow path 2 is provided with a filter 5, the total heat exchanger 4, the humidifier 6, the air supply side heat exchanger 7, and the blower 8 in order from the outside air inlet 2 a side toward the air inlet 2 b. The return air flow path 3 is provided with a filter 9, the total heat exchanger 4, the return air side heat exchanger 10, and a blower 11 in this order from the return air port 3a to the exhaust port 3b.

なお、給気流路2内におけるフィルタ5は、例えばプレフィルタ5aと中性能フィルタ5bとの2段構成のものとしてある。   The filter 5 in the air supply channel 2 has a two-stage configuration of, for example, a pre-filter 5a and a medium performance filter 5b.

また、上記還気流路3におけるフィルタ9と全熱交換器4との間には、冷媒回路の圧縮機12を設けてあり、同圧縮機12からの冷媒は、前記給気側熱交換器7と還気側熱交換器10をこの順に、またはその逆となるように四方弁13により切替えて供給され、アキュムレータ14を介して圧縮機に戻される構成となっており、上記四方弁の切替えによって暖房運転と冷房運転が切替えられる。   Further, a compressor 12 of a refrigerant circuit is provided between the filter 9 and the total heat exchanger 4 in the return air flow path 3, and the refrigerant from the compressor 12 is supplied to the supply side heat exchanger 7. And the return air side heat exchanger 10 are switched and supplied by the four-way valve 13 in this order or vice versa, and are returned to the compressor via the accumulator 14. Switching between heating operation and cooling operation.

なお、上記圧縮機12、四方弁13およびアキュムレータ14は全熱交換器4と還気側熱交換器10との間に設ける場合もあるし、他の位置に設ける場合もある。
また、図1中において符号15、16はそれぞれ第1熱交換器、第2熱交換器用の各膨張弁、17、18はそれぞれ給気側熱交換器7用、還気側熱交換器10用の逆止弁を示している。
The compressor 12, the four-way valve 13 and the accumulator 14 may be provided between the total heat exchanger 4 and the return air side heat exchanger 10, or may be provided at other positions.
Further, in FIG. 1, reference numerals 15 and 16 denote expansion valves for the first heat exchanger and the second heat exchanger, respectively, and 17 and 18 denote the supply side heat exchanger 7 and the return air side heat exchanger 10, respectively. The check valve is shown.

具体的には、冷房運転時には図1中に実線矢印で示されるように、圧縮機12からの冷媒が四方弁13を介して還気側熱交換器10に送られ、還気流路3を流過する空気との熱交換により凝縮されて給気側熱交換器7に送られ、同給気側熱交換器において蒸発させられて給気流路2内を流過する空気を冷却してアキュムレータ14に送られ、同アキュムレータにて気液分離されて圧縮機12に戻される。
なお、給気側熱交換器7にて冷却された空気は被空調室に送られる。
Specifically, during the cooling operation, as indicated by solid arrows in FIG. 1, the refrigerant from the compressor 12 is sent to the return air side heat exchanger 10 through the four-way valve 13 and flows through the return air flow path 3. The air is condensed by heat exchange with excess air and sent to the supply air side heat exchanger 7, evaporated in the supply air side heat exchanger and cooled in the supply air passage 2 to cool the accumulator 14. The gas is separated into gas and liquid by the accumulator and returned to the compressor 12.
In addition, the air cooled with the air supply side heat exchanger 7 is sent to an air-conditioned room.

また、暖房運転時には図1中に破線矢印で示されるように、圧縮機12からの冷媒が四方弁13を介して給気側熱交換器7に送られ、給気流路2を流過する空気との熱交換によって凝縮して給気流路内の空気を加熱し、凝縮した冷媒は還気側熱交換器10に送られて蒸発させられて還気流路3内を流過する空気の熱を奪い、その後アキュムレータにて気液分離されて圧縮機12に戻される。
なお、給気側熱交換器7にて加熱された空気は被空調室に送られる。
Further, during the heating operation, as indicated by broken line arrows in FIG. 1, the refrigerant from the compressor 12 is sent to the supply side heat exchanger 7 through the four-way valve 13 and flows through the supply passage 2. The heat of the air that flows through the return air passage 3 is condensed by heat exchange with the air and heats the air in the air supply passage, and the condensed refrigerant is sent to the return air side heat exchanger 10 to be evaporated. The gas is then separated into gas and liquid by an accumulator and returned to the compressor 12.
In addition, the air heated with the air supply side heat exchanger 7 is sent to an air-conditioned room.

しかして、本発明の装置においては前記給気側熱交換器7の下方にドレンパン19を設けてあって、冷房運転時において蒸発器として作用する給気側熱交換器表面で発生する凝縮水を捕集するようになっている。   Therefore, in the apparatus of the present invention, a drain pan 19 is provided below the air supply side heat exchanger 7, and condensed water generated on the surface of the air supply side heat exchanger that acts as an evaporator during cooling operation is collected. It is supposed to collect.

そして、上記ドレンパン19の底部に一端が接続された送水手段たる送水管20の他端が、仕切り板1aを経て、還気側熱交換器10の上流側に設けた給水手段たる加湿器21に接続されており、前記ドレンパンで捕集された凝縮水が上記加湿器21の加湿用水として用いられるようになっていて、加湿器には例えば気化式加湿器を使用する。   And the other end of the water supply pipe 20 as one of the water supply means connected at one end to the bottom of the drain pan 19 is connected to the humidifier 21 as the water supply means provided on the upstream side of the return air side heat exchanger 10 via the partition plate 1a. Condensed water that is connected and collected by the drain pan is used as humidifying water for the humidifier 21, and a vaporizing humidifier is used as the humidifier, for example.

上記送水管20は加湿器21側に向かって下向きの勾配を付してあって、凝縮水は自然落下により流れて供給されるようにしてあるが、装置の仕様によっては上述のような勾配を付すことができない場合もあるので、このような場合には送水管の途中に適宜送水用のポンプを設ける。
なお、図1中の符号22は還気側熱交換器まわりの余剰水を捕集するためのドレンパンを示し、同ドレンパンに滴下する水(加湿用の余剰水や暖房運転時における凝縮水)は外部に排出される。
The water pipe 20 has a downward gradient toward the humidifier 21 side, and the condensed water flows and is supplied by natural fall. However, depending on the specifications of the apparatus, the gradient as described above may be used. In some cases, a pump for water supply is appropriately provided in the middle of the water supply pipe.
In addition, the code | symbol 22 in FIG. 1 shows the drain pan for collecting the surplus water around a return air side heat exchanger, and the water dripped in the drain pan (the surplus water for humidification or the condensed water at the time of heating operation) is It is discharged outside.

上述のように、冷房運転時の給気側熱交換器7で凝縮した水が還気側熱交換器10の上流部に設けられた加湿器21によって気化されて還気側熱交換器に放出され、したがって還気側熱交換器10にて放出された熱を加湿器からの水分が奪い、排気温度が低下させられる。   As described above, the water condensed in the supply air side heat exchanger 7 during the cooling operation is vaporized by the humidifier 21 provided upstream of the return air side heat exchanger 10 and discharged to the return air side heat exchanger. Accordingly, the moisture released from the return air side heat exchanger 10 is deprived of moisture from the humidifier, and the exhaust temperature is lowered.

また、冷房運転時において凝縮器として作用している還気側熱交換器10は加湿器21からの水分によって温度が低下させられるので、凝縮温度が低下し、したがって圧縮機における運転動力を減少せしめることができ、省エネルギ化を期すことができる。   Further, since the temperature of the return air side heat exchanger 10 acting as a condenser during the cooling operation is lowered by moisture from the humidifier 21, the condensing temperature is lowered, and thus the operating power in the compressor is reduced. This can save energy.

図2は、上述した構成の本発明の装置により、冷房運転時における空気の状態の一例を湿り空気線図に示したものであり、給気風量が6000CMH、給気側熱交換器7入口における空気が乾球温度で29.4℃、湿球温度で23.0℃、給気側熱交換器の蒸発器能力が14.7kWであるとして計算を行うと、給気側熱交換器出口における空気は乾球温度で26.0℃、湿球温度で21.0℃となり、凝縮水の発生量は10.8g/hとなる。   FIG. 2 is a wet air diagram showing an example of the air state during cooling operation by the apparatus of the present invention having the above-described configuration. The supply air volume is 6000 CMH, and the supply air side heat exchanger 7 has an inlet. When calculation is performed assuming that the air is 29.4 ° C. at the dry bulb temperature, 23.0 ° C. at the wet bulb temperature, and the evaporator capacity of the supply side heat exchanger is 14.7 kW, at the supply side heat exchanger outlet Air has a dry bulb temperature of 26.0 ° C. and a wet bulb temperature of 21.0 ° C., and the amount of condensed water generated is 10.8 g / h.

そして、加湿器21入口における空気を乾球温度で31.1℃、湿球温度で24.8℃、加湿器による加湿効率を30%であるとすると、加湿器21出口における空気温度は乾球温度で30.0℃となり、すなわち凝縮水による加湿を行わない場合に比して1.1℃低下し、したがって排気口3bから外部に放出される排気温度も1.1℃低下させることができる。   If the air at the inlet of the humidifier 21 is 31.1 ° C. at the dry bulb temperature, 24.8 ° C. at the wet bulb temperature, and the humidification efficiency by the humidifier is 30%, the air temperature at the outlet of the humidifier 21 is dry bulb. The temperature is 30.0 ° C., that is, 1.1 ° C. lower than when humidification with condensed water is not performed. Therefore, the exhaust temperature discharged from the exhaust port 3b to the outside can also be reduced by 1.1 ° C. .

また、還気側熱交換器10における冷媒の凝縮温度を、還気側熱交換器に流入する空気の温度(入口温度)よりも乾球温度にして15℃高いものであると仮定して圧縮機動力を計算すると、凝縮水による加湿を行わない場合は3.43kW、加湿を行う場合は3.31kWとなり、凝縮水による加湿を行った場合には3.5%の動力低減を期待することができる。   Further, it is assumed that the condensation temperature of the refrigerant in the return air side heat exchanger 10 is 15 ° C. higher than the temperature of the air flowing into the return air side heat exchanger (inlet temperature) by a dry bulb temperature. When the mobility is calculated, it is 3.43 kW when humidification with condensed water is not performed, 3.31 kW when humidification is performed, and a 3.5% reduction in power is expected when humidification with condensed water is performed. Can do.

上述した実施例においては、給気流路2と還気流路3の空気を全熱交換器4にて熱交換する構成としてあるが、全熱交換器を設けない場合もある。   In the embodiment described above, the air in the supply air flow path 2 and the return air flow path 3 is configured to exchange heat with the total heat exchanger 4, but the total heat exchanger may not be provided.

図3は給水手段の他の例を示すものであり、同図3に示される例においては前記加湿器21に代えて、受水器たる受水皿23を還気側熱交換器10の上部に設けたものとしてあり、この受水皿は底部に多数の通水用の孔24、24を有し、これらの孔から水を滴下せしめて還気側熱交換器10の表面を流下させる構成となっていて、孔の数や径によって水の滴下量を適宜設定できるようになっている。   FIG. 3 shows another example of the water supply means. In the example shown in FIG. 3, instead of the humidifier 21, a water receiving tray 23 serving as a water receiver is arranged above the return air side heat exchanger 10. The water receiving tray has a plurality of holes 24 and 24 for passing water at the bottom, and the surface of the return air side heat exchanger 10 flows down by dripping water from these holes. Thus, the amount of water dropped can be set as appropriate depending on the number and diameter of the holes.

図4は給水手段のさらに他の例を示すものであり、受水器を枠25内に収容した保水性材26で構成し、この保水性材上に供給した水が保水性材の飽和量を超えると下側から還気側熱交換器10に滴下するようにしてある。
上記保水性材26は、供給した水がほぼ均等に還気側熱交換器に滴下するものが好適であり、例えばウレタンフォーム等の発泡性樹脂材や海面等のスポンジ状のものを用いることができる。
FIG. 4 shows still another example of the water supply means, in which a water receiver is constituted by a water retention material 26 accommodated in a frame 25, and the water supplied on the water retention material is the saturation amount of the water retention material. If it exceeds, it will be dripped at the return air side heat exchanger 10 from the lower side.
The water-retaining material 26 is preferably one in which the supplied water drops almost uniformly on the return air side heat exchanger. For example, a foamable resin material such as urethane foam or a sponge-like material such as the sea surface is used. it can.

また、上述した給水手段のほかにも、ポンプやエジェクタを用いて強制的に凝縮水を還気側熱交換器10の入口にスプレーする構成とする場合もあるし、還気側熱交換器の上流側において凝縮水を水幕状に滴下する構成とする場合もある。   In addition to the water supply means described above, there may be a configuration in which condensed water is forcibly sprayed to the inlet of the return air side heat exchanger 10 using a pump or an ejector. There is a case where the condensed water is dropped in a water curtain shape on the upstream side.
