【特許文献1】
特開2000−74411号公報
【0004】
【発明が解決しようとする課題】
しかしながら、設置場所の設置条件によっては、室外機が室内機よりも高い位置に設置される場合があり、この場合は室内機の蒸発器で発生した結露水を高い位置の凝縮器まで運ぶ事ができないために、ただ単に排水されるのみで有った。
【0005】
【問題点を解決するための手段】
この発明はこの点に着目し上記欠点を解決する為、特にその構成を、圧縮機と凝縮器、絞り装置を備える室外機と、蒸発器と送風ファンを備える室内機を、冷媒配管で環状に接続た空気調和機に於いて、前記室内機と室外機の間に、蒸発器で発生した結露水を溜めるドレンタンクと、このドレンタンクの水位を検知する水位検知手段と、前記ドレンタンクの結露水を凝縮器の上部に散布するポンプを備えたポンプユニットを設けたものである。
【0006】
これによって、前記室外機が室内機よりも高い位置に設置される場合でも、室内機の蒸発器で発生した結露水を高い位置の凝縮器まで運ぶ事ができ、結露水を凝縮器に滴下、または散布することにより熱交換効率を向上し、消費電力を低減するものである。
【0007】
【発明の実施の形態】
以下この発明の一実施例を図面をもとに説明すれば、1は空気調和機の室内機で、室内の壁等に設置され、樹脂製の筐体2内部にフィンチューブ式の熱交換器から成る蒸発器3とクロスフロー式の室内送風ファン4と、この室内送風ファン4を回転する室内送風モータ5と、この室内送風モータ5等に接続され室内機1の運転制御を行う制御装置6を備え、室内吸込口7から室内空気を吸込み熱交換して室内吹出口8から室内に戻す事によって室内空気の温度調節を行うものである。
【0008】
9は前記蒸発器3で発生した結露水を集めて落差により屋外へ排水するドレンパンで、前記蒸発器3下部に設けられている。
10はドレンホース等の排水路で、一端を前記ドレンパン9に接続し、他端を室外に延出するものである。
【0009】
11は屋外のベランダ等の天井に吊り下げられて設置する室外機で、前記室内機1よりも高い位置に据え付けられており、壁等を貫通して前記室内機1と冷媒配管12にて接続されるものであり、筐体13内には圧縮機14とフィンチューブ式の熱交換器から成る凝縮器15とプロペラ式の室外送風ファン16と、室外送風モータ17等を備え、室外吸込口18から空気を吸い込んで前記凝縮器15を冷却して室外吹出口19から吹き出すものである。
【0010】
20は前記室内機1と室外機11の間の外壁21等に取り付けられたポンプユニットで、前記室内機1からの排水路10を接続し、この排水路10よりの結露水を溜めるドレンタンク22と、このドレンタンク22の水位を検知するフロートスイッチ等から成る水位検知手段23と、ドレンタンク22の結露水を前記室外機11の凝縮器15の上部に散布または滴下するためのポンプ24を備えている。
【0011】
25は前記ポンプ24から室外機11へ結露水を送る送水管である。
26は前記凝縮器15と蒸発器3との間の室外機11内に備えた絞り装置で、膨脹弁やキャピラリーチューブ等から成るものである。
【0012】
図2の系統図の実線は冷凍回路を示し、一点鎖線は排水回路を、矢印実線は制御回路を示すものである。
作動について説明すれば、運転スイッチ(図示せず)等の操作によって冷房運転が開始されれば、圧縮機14が始動する事で冷凍回路内に冷媒が循環を始め、蒸発器3は低温に、凝縮器15は高温になると共に室内送風モータ5と室外送風モータ17が回転する。
【0013】
室内の空気は室内吸込口7より室内機1内に吸い込まれ、蒸発器3で冷却され室内吹出口8から吹き出される。この時蒸発器3には結露水が発生し、この結露水はドレンパン9で集められ、排水路10を通って屋外のポンプユニット20のドレンタンク22へ排水される。
【0014】
ドレンタンク22では水位検知手段23にてタンク内の水位を検知し、制御装置6にて結露水の水位に応じてポンプ24を作動する。
【0015】
ポンプ24が作動すれば送水管25を通って結露水が高温の凝縮器15の上部に散布または滴下する事で、凝縮器15の熱交換効率を向上し、消費電力を低下するものであり、また、結露水のほとんどは蒸発するので、見苦しいドレン配管を設ける必要がないものである。
【0016】
また消費電力が低下する事でCOP(エネルギー消費効率)も向上するものである。
また室外吸込口18から吸い込まれた空気は凝縮器15を冷却後、室外送風ファン16によって蒸発した結露水と共に室外吹出口19より吹き出されるものである。
また室内機1と室外機11が見かけ上同じ高さの場合でも、蒸発器3から落差によって結露水を凝縮器15の上部に散布する事はできないため、やはりポンプユニット22を必要とするものである。
【0017】
【発明の効果】
以上のようにこの発明によれば、たとえ室外機が室内機よりも高い位置に据付られる場合でも、ポンプユニットによって結露水を凝縮器に散布する事ができ、凝縮器の熱交換効率を向上し、消費電力を低下するものである。

[0002]
[Prior art]
Conventionally, to improve heat exchange efficiency, there is an air conditioner that drops condensed water generated in the evaporator of the indoor unit into the condenser of the outdoor unit, and reducing power consumption by improving the heat exchange efficiency It was useful. (For example, see Patent Document 1)
[0003]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 2000-74411
[Problems to be solved by the invention]
However, depending on the installation conditions of the installation location, the outdoor unit may be installed at a higher position than the indoor unit.In this case, the condensate generated in the evaporator of the indoor unit may be transported to the condenser at a higher position. Because they couldn't, they were simply drained.
[0005]
[Means for solving the problem]
The present invention pays attention to this point and solves the above-mentioned drawbacks. In the connected air conditioner, between the indoor unit and the outdoor unit, a drain tank for storing dew water generated by an evaporator, a water level detecting unit for detecting a water level of the drain tank, and a dew condensation for the drain tank A pump unit provided with a pump for spraying water on the upper part of the condenser is provided.
[0006]
Thereby, even when the outdoor unit is installed at a position higher than the indoor unit, it is possible to carry the dew water generated in the evaporator of the indoor unit to the condenser at a high position, and to drop the dew water on the condenser, Alternatively, the heat exchange efficiency is improved by spraying, and the power consumption is reduced.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an indoor unit of an air conditioner, which is installed on an indoor wall or the like and has a fin tube type heat exchanger inside a resin housing 2. , A cross-flow type indoor blower fan 4, an indoor blower motor 5 for rotating the indoor blower fan 4, and a control device 6 connected to the indoor blower motor 5 and the like to control the operation of the indoor unit 1. The temperature of the indoor air is adjusted by sucking indoor air from the indoor air inlet 7 and exchanging heat to return the indoor air from the indoor air outlet 8.
[0008]
Reference numeral 9 denotes a drain pan that collects dew water generated in the evaporator 3 and drains the water to the outside by a head. The drain pan 9 is provided below the evaporator 3.
A drain passage 10 such as a drain hose has one end connected to the drain pan 9 and the other end extending out of the room.
[0009]
Reference numeral 11 denotes an outdoor unit which is suspended from the ceiling of an outdoor veranda or the like and is installed at a position higher than the indoor unit 1 and penetrates a wall or the like and is connected to the indoor unit 1 by a refrigerant pipe 12. The housing 13 includes a compressor 14, a condenser 15 formed of a fin tube type heat exchanger, a propeller type outdoor blower fan 16, an outdoor blower motor 17, and the like. This cools the condenser 15 by blowing in air from the outside and blows it out from the outdoor outlet 19.
[0010]
Reference numeral 20 denotes a pump unit mounted on an outer wall 21 or the like between the indoor unit 1 and the outdoor unit 11, which connects a drainage passage 10 from the indoor unit 1, and a drain tank 22 for storing dew condensation water from the drainage passage 10. A water level detecting means 23 comprising a float switch for detecting the water level of the drain tank 22; and a pump 24 for spraying or dripping the dew condensation water of the drain tank 22 onto the upper part of the condenser 15 of the outdoor unit 11. ing.
[0011]
Reference numeral 25 denotes a water pipe for sending dew water from the pump 24 to the outdoor unit 11.
Reference numeral 26 denotes a throttle device provided in the outdoor unit 11 between the condenser 15 and the evaporator 3, and comprises an expansion valve, a capillary tube and the like.
[0012]
The solid line in the system diagram of FIG. 2 indicates a refrigeration circuit, the one-dot chain line indicates a drain circuit, and the solid arrow line indicates a control circuit.
In operation, if the cooling operation is started by operating an operation switch (not shown) or the like, the refrigerant starts to circulate in the refrigeration circuit by starting the compressor 14, and the evaporator 3 cools down. The temperature of the condenser 15 becomes high, and the indoor blower motor 5 and the outdoor blower motor 17 rotate.
[0013]
The indoor air is drawn into the indoor unit 1 from the indoor suction port 7, cooled by the evaporator 3, and blown out from the indoor outlet 8. At this time, condensed water is generated in the evaporator 3, and the condensed water is collected by a drain pan 9 and drained to a drain tank 22 of an outdoor pump unit 20 through a drain passage 10.
[0014]
In the drain tank 22, the water level in the tank is detected by the water level detecting means 23, and the control device 6 operates the pump 24 in accordance with the water level of the dew condensation water.
[0015]
If the pump 24 operates, the dew condensation water is sprayed or dropped on the upper part of the high-temperature condenser 15 through the water supply pipe 25, thereby improving the heat exchange efficiency of the condenser 15 and reducing the power consumption. Further, since most of the dew condensation water evaporates, it is not necessary to provide an unsightly drain pipe.
[0016]
In addition, the COP (energy consumption efficiency) is improved by reducing the power consumption.
Further, the air sucked from the outdoor suction port 18 cools the condenser 15 and is blown out from the outdoor blowout port 19 together with the dew water evaporated by the outdoor blower fan 16.
Also, even when the indoor unit 1 and the outdoor unit 11 are apparently at the same height, since the dew condensation water cannot be sprayed to the upper part of the condenser 15 due to the head from the evaporator 3, the pump unit 22 is also required. is there.
[0017]
【The invention's effect】
As described above, according to the present invention, even when the outdoor unit is installed at a position higher than the indoor unit, dew condensation water can be sprayed on the condenser by the pump unit, thereby improving the heat exchange efficiency of the condenser. Power consumption.
