Description
本考案は、分離型空気調和装置における冷房運転時の省電力化策に関する。 The present invention relates to a power saving measure at the time of cooling operation in a separation type air conditioner.
夏季の家庭における電力使用量の内３０％以上は空気調和装置（エアコン、以下特に断らない限り以下エアコンという）の冷房運転によるものといわれている。従ってエアコン冷房運転時の省エネルギー化方策、特に新たに開発・製造するエアコンへの適用性は勿論、既存のエアコンにも適用できる方策、への社会的要求度は今非常に高いと言える。
従来エアコン冷房運転時の水の気化冷却作用を応用した省電力化策あるいは関連方策としては、室外機凝縮器の熱交換効率を上げる方法、室内機で生成される凝縮水の処理を行う方法、あるいは室外機排熱風の冷却方法等、が提案され実行されている。
凝縮器の熱交換効率を上げる方法として具体的には、冷房運転中室内機によって生じた結露水を霧化した後室外機に導き、室外機の凝縮器に吹き付けて凝縮器冷却に利用する方法（特許文献１）、冷房運転中室内機によって生じた凝縮水を室外機熱交換器即ち凝縮器の空気吹きだし側に隣接して設けた凝縮水蒸発手段に導いて凝縮水を蒸発処理する方法（特許文献２）、室外機排気側面に多数の吸水シートを保持・立設した給水体ユニットと該給水体ユニットを受容して給水体シートの下部を水で湿潤する水受け容器からなる冷却装置を設け、該冷却装置中に凝縮器から排出される排熱風を通過させることによって排熱を冷却し、屋外機から周辺に排出される排熱風の弊害を防止する方法（特許文献３）等がある。
It is said that 30% or more of electric power consumption in summer homes is due to cooling operation of an air conditioner (air conditioner, hereinafter referred to as an air conditioner unless otherwise specified). Therefore, it can be said that the social demand for energy-saving measures at the time of air-conditioner cooling operation, particularly measures applicable to existing air-conditioners as well as applicability to newly developed and manufactured air-conditioners, is very high.
As a power-saving measure or a related measure that applies the evaporative cooling action of water during conventional air-conditioner cooling operation, a method of increasing the heat exchange efficiency of the outdoor unit condenser, a method of treating the condensed water generated in the indoor unit, Or the cooling method etc. of an outdoor unit exhaust hot air are proposed and implemented.
Specifically, as a method of increasing the heat exchange efficiency of the condenser, the condensed water generated by the indoor unit during the cooling operation is atomized, guided to the outdoor unit, and sprayed to the condenser of the outdoor unit and used for cooling the condenser (Patent Document 1), a method in which condensed water generated by an indoor unit during cooling operation is led to a condensed water evaporating means provided adjacent to an air blowing side of an outdoor unit heat exchanger, that is, a condenser to evaporate condensed water ( Patent Document 2), a cooling device comprising a water supply unit that holds and stands a large number of water absorbing sheets on the exhaust side of an outdoor unit, and a water receiving container that receives the water supply unit and wets the lower part of the water supply sheet with water. There is a method for cooling the exhaust heat by passing the exhaust hot air exhausted from the condenser through the cooling device to prevent the harmful effect of the exhaust hot air exhausted from the outdoor unit to the periphery (Patent Document 3), etc. .
しかし上記特許文献１の方法は、室内機によって生成される結露水（凝縮水）の処理方策としての凝縮器冷却であり、室外機における前記結露水の処理効果は十分であっても、凝縮性能向上効果は結露水（凝縮水）量からもあるいは凝縮器における気化冷却効率の面からも十分であるとはいえない。
また、特許文献２の方法は室内機によって生成された結露水（凝縮水）の処理を目的としたもの、特許文献３の方法による冷却効果は、あくまでも凝縮器通過後の排熱風に対してのものであって、凝縮器冷却という点からは不十分である。
However, the method of the above-mentioned Patent Document 1 is condenser cooling as a treatment strategy for the condensed water (condensed water) generated by the indoor unit. Even if the treatment effect of the condensed water in the outdoor unit is sufficient, the condensation performance The improvement effect is not sufficient from the amount of condensed water (condensed water) or from the aspect of evaporative cooling efficiency in the condenser.
In addition, the method of Patent Document 2 is intended for the treatment of condensed water (condensed water) generated by an indoor unit, and the cooling effect of the method of Patent Document 3 is only for the exhaust hot air after passing through the condenser. However, it is insufficient in terms of condenser cooling.
一方、空気調和機の省エネルギー化を直接的な目的とした方法として、室外機の外側周辺に水を噴霧することによって凝縮器に送風される外気を冷却し、省エネルギー化を図ろうとする試みもある（非特許文献１）。しかしこれは室外機外辺の空気冷却による凝縮器冷却効率向上方策ではあるが、凝縮器冷却の為の気化冷却が凝縮器に対して直接行われるものではなく周辺外気に対して行われるものであり、したがって凝縮器冷却効果は不十分であり、また噴霧すべき水量も多くなる恐れもある。 On the other hand, as a method directly aimed at energy saving of the air conditioner, there is an attempt to save energy by spraying water around the outside of the outdoor unit to cool the outside air blown to the condenser. (Non-Patent Document 1). However, this is a measure to improve the condenser cooling efficiency by air cooling outside the outdoor unit, but evaporative cooling for cooling the condenser is not performed directly on the condenser but on the ambient outside air. Therefore, the condenser cooling effect is insufficient, and the amount of water to be sprayed may be increased.
本考案は、エアコン冷房時における主として室外機内の凝縮器駆動の省電力化を上記各従来方法に比べて効率化し、かつ既存のエアコンにおいても比較的簡易に適用できる方策を提案するものである。 The present invention proposes a measure that is more efficient than the conventional methods in the above-described conventional methods, and that can be applied relatively easily to existing air conditioners.
エアコン室外機中の凝縮器の凝縮効率を向上させる方策として、エアコン室外機を構成する圧縮機、凝縮器、送風機に対し、前記送風機から前記凝縮器に送風される送風中および前記凝縮器の冷却用フィンに対して直接、霧化した水粒子を噴霧する噴霧器を設ける。
ここで噴霧前記器への水の供給は噴霧が必要十分な量行えるように外部の水道から自動的に噴霧器に対して供給されるようにする。
前記噴霧器によって送風中に霧化され噴霧された微細水粒子は送風中で気化冷却によって送風を冷却する。また凝縮器の冷却用フィンに対して直接噴霧され（フィンに）付着した微細水粒子は送風機からの送風によって効率よく気化冷却される。これらの気化冷却の結果、凝縮器における冷媒と外気との熱交換の効率が上がり、エアコンの電力使用効率が向上する。
即ち、上記方策によって凝縮器における熱交換効率は、単に送風機の送風による凝縮器冷却あるいは前記凝縮器冷却効率向上策による冷却に比べても、大幅に向上する。
As a measure for improving the condensation efficiency of the condenser in the air conditioner outdoor unit, the compressor, the condenser, and the blower constituting the air conditioner outdoor unit are being blown from the blower to the condenser, and the condenser is cooled. A sprayer is provided for spraying atomized water particles directly on the working fin.
Here, water is supplied to the sprayer automatically from an external water supply so that spraying can be performed in a necessary and sufficient amount.
The fine water particles atomized and sprayed during blowing by the sprayer cool the blowing by evaporative cooling during blowing. Moreover, the fine water particles sprayed directly on the fins for cooling the condenser (attached to the fins) are efficiently vaporized and cooled by blowing air from the blower. As a result of the evaporative cooling, the efficiency of heat exchange between the refrigerant and the outside air in the condenser is increased, and the power usage efficiency of the air conditioner is improved.
In other words, the heat exchange efficiency in the condenser is greatly improved by the above-mentioned measures even when compared with the condenser cooling simply by the blower of the blower or the cooling by the condenser cooling efficiency improvement measure.
上記の如くエアコン室外機を構成・動作させることによって、凝縮器における凝縮器周辺外気と凝縮器内冷媒との熱交換効率、冷媒冷却能力は向上し、空気調和機としての電力消費量の低減即ち省エネルギー化を図ることができる。 By configuring and operating the air conditioner outdoor unit as described above, the heat exchange efficiency between the outside air around the condenser and the refrigerant in the condenser in the condenser and the refrigerant cooling capacity are improved, and the power consumption as an air conditioner is reduced. Energy saving can be achieved.
エアコン室外機の送風機と凝縮器の間に水を霧化（微細粒子化）凝縮器に噴霧するための噴霧器を設ける。噴霧器は単数に限定したものではなく、凝縮器において効率的・効果的に熱交換が行えるように適当な位置に分散して複数個設けてもよい。また噴霧器から噴霧する水は必要十分な量確保するため、基本的には外部から、例えば水道から、噴霧器に対して必要量を自動的に供給する。但し水道水の消費量を低減するため、凝縮器に噴霧された水の気化残の分は下部に設けた受け皿で受けて噴霧用に再利用してもよい。また、室内機で生成される結露水（凝縮水）を室外機に導いて前記受け皿に蓄え噴霧用に使うことも有効である。
又噴霧すべき水を水道から自動的に噴霧機に供給する代わりに、上記受け皿に定期的に外部から水を（手動で）補給する方法もある。
A sprayer is provided between the blower of the air conditioner outdoor unit and the condenser for spraying water onto the atomization (fine particle) condenser. The number of atomizers is not limited to a single one, and a plurality of atomizers may be provided dispersed at appropriate positions so that heat can be exchanged efficiently and effectively in the condenser. Further, in order to secure a necessary and sufficient amount of water to be sprayed from the sprayer, basically, the required amount is automatically supplied to the sprayer from the outside, for example, from a water supply. However, in order to reduce the consumption of tap water, the remaining vaporized water sprayed on the condenser may be received by a tray provided at the bottom and reused for spraying. It is also effective to guide the condensed water (condensed water) generated in the indoor unit to the outdoor unit and store it in the tray for spraying.
Further, instead of automatically supplying water to be sprayed from the water supply to the sprayer, there is a method in which water is manually (manually) supplied to the tray from the outside.

以上の如く従来の空気調和機室外機に、噴霧器１０５を付加し、噴霧器に対して必要十分な水を供給して水を微細粒子化して凝縮器フィンに噴霧せしめ、凝縮器における単なる送風機からの外気送風による冷却を、気化冷却された送風および凝縮器フィンに噴霧された水の微細粒子の気化冷却による冷却促進によって、凝縮器中の冷媒への冷却効果を向上させ、その結果としてエアコンとしての冷房運転に際しての電力消費量を低減することができる。 As described above, the nebulizer 105 is added to the conventional outdoor air conditioner outdoor unit, and necessary and sufficient water is supplied to the nebulizer so that the water is atomized and sprayed on the condenser fins.
