てすらアルミサッシなどの普及で気密性の高い屋内環境
が創生されてきており、特に長期的な展望で省エネルギ
ーを先取りした高気密高断熱住宅等に見られるような非
常に気密性の高い住宅が現出してきている。However, looking at recent trends in houses and their building materials, the spread of aluminum sashes and the like in even ordinary houses has created a highly airtight indoor environment. From a prospective perspective, very airtight houses such as high airtight and highly insulated houses that anticipate energy saving are emerging.
【0027】このような住宅は省エネルギーでかつ保温
性などに勝れている反面、家屋に新建材を多く使用され

知らず知らずの内に屋内の空気の汚染度も高くなってい
る。従って、換気性能を大幅に向上させなければならな
い必要性が生じてきている。Although such a house is excellent in energy saving and heat insulation, it tends to use a lot of new building materials in the house, so indoor air is unknowingly unknowingly harmful such as formaldehyde. The pollution level is also increasing. Therefore, there is a need to significantly improve ventilation performance.
【0028】ところで、このような住宅の換気手段とし
て、従来の換気機能を備えたヒートポンプ式冷暖房空気
調和装置を利用しようとすれば、上記に示した、その構
成では、周知の通り屋内の気密性が高くなればなるほど
通風抵抗が大きくなり、その分換気量が少なくなるのは
自明のことである。By the way, if it is attempted to use a conventional heat pump type air conditioner having a ventilation function as a ventilation means for such a house, the above-mentioned configuration has a well-known indoor airtightness. It is self-evident that the higher is the higher the ventilation resistance and the lower the ventilation.
【0029】そこで換気性能を向上させるには、給気装

排気送風機、それに外気進入ダクト,内気排出ダクト,
接続ダクト,室内吹き出しダクト等の構成部品のサイズ
を大きくするか、あるいはそれらの送風機の回転数を増
加させねばならなかった。To improve the ventilation performance, an indoor air supply blower built in the air supply device and an exhaust air blower provided in the exhaust device, an outside air entry duct, an inside air discharge duct,
It is necessary to increase the size of components such as a connection duct and an indoor outlet duct, or to increase the rotation speed of the blower.
【0030】構成部品のサイズを大きくする場合、住宅

置場所は必然的に限定され、それは重量やコストから見
ても現実的に甚だ難しいことで、より小型,軽量かつ低
コストが要求されていた。In the case of increasing the size of the component parts, a large air supply device, a large exhaust device, an outside air entrance duct, an inside air exhaust duct, a connection duct, an indoor outlet duct, and the like are to be installed behind the narrow ceiling of the house. Therefore, the installation place is necessarily limited, which is extremely difficult from the viewpoint of weight and cost, and a smaller, lighter, and lower cost is required.
【0031】従って残された選択肢として、室内給気送
風機や排気送風機などの回転数を増速させる以外、打つ
手がないというのが実態であった。その結果、当然のこ
とではあるが、屋内においてはそれらの送風機の騒音に
悩まされ、かつ消費電力の増大を招いていたため、低騒
音で、消費電力の低下が強く要求されていた。Therefore, as a remaining option, in reality, there is no action other than increasing the rotation speed of the indoor air supply blower, the exhaust blower, and the like. As a result, as a matter of course, indoors are bothered by the noise of these blowers and have caused an increase in power consumption. Therefore, there has been a strong demand for low noise and low power consumption.
【0032】また、サイズの大きな給気装置や排気装

ヒートポンプ式冷暖房空気調和装置の構成では、その構
成部品をそれぞれ個別に天井裏に取り付けねばならず、
結局多くの手間と膨大な工事費が掛かるため、取り付け
工事性の向上も要求されていた。In addition, even if the house is large enough to have a large-sized air supply device and exhaust device, and their respective ducts and the like installed above the ceiling, the conventional heat pump air conditioning and cooling air conditioner described above can be used. In the configuration, each of its components must be individually mounted on the ceiling,
As a result, much labor and huge construction costs are required, and therefore, improvement in installation workability has been required.
【0033】その上、近年冷媒で使用されるフロン系化
学物質はオゾン層の破壊と地球の温暖化を引き起こす物
質として規制もしくは不使用が叫ばれていて、代替冷媒
として自然冷媒等が注目されてきている。In addition, the use or regulation of Freon-based chemical substances used in refrigerants in recent years has been called out as substances causing destruction of the ozone layer and global warming, and natural refrigerants and the like have been attracting attention as alternative refrigerants. ing.
【0034】しかしながらこの自然冷媒の多くはプロパ
ン,ブタンなどに見られるように可燃性の物質であり、
上記に示した従来の構成では、天井裏に取り付けられた
給気装置の冷媒系熱交換器等から冷媒を漏らさないため
に、冷凍サイクル内の密閉性を一段と厳しく管理しなけ
ればならず、製造コスト及び工事費が非常に高くなるた
め、低コストと工事の簡略化が要求されていた。However, most of these natural refrigerants are flammable substances as seen in propane, butane and the like.
In the above-described conventional configuration, the hermeticity in the refrigeration cycle must be more strictly controlled in order to prevent the refrigerant from leaking from the refrigerant-based heat exchanger of the air supply device mounted above the ceiling. Since the cost and the construction cost are extremely high, low cost and simplification of the construction have been required.
【0035】また、従来の構成では、屋外の外気温が低
下すればするほど、室外熱交換器からの吸熱量が減るた
め、暖房能力が低下し、かつ冷媒系熱交換器の凝縮温度
が下がるため、室内吹き出し口から屋内に吹き出す吹き
出し気流の温度も低下し、屋内の快適温度が著しく損な
われていたため、暖房性能と快適性の向上が要求されて
いた。In the conventional configuration, the lower the outside air temperature is, the smaller the amount of heat absorbed from the outdoor heat exchanger is, so that the heating capacity is reduced and the condensation temperature of the refrigerant heat exchanger is lowered. For this reason, the temperature of the airflow blown out from the indoor outlet to the inside of the room has also been lowered, and the indoor comfortable temperature has been significantly impaired. Therefore, improvements in heating performance and comfort have been required.
【0036】更に従来の構成では、冷房時の除湿は十分
能力を発揮するものの、温度制御に難点があって、冷え

そのままでは屋内の天井面や内壁面の結露やカビを防止

湿性能の向上が要求されていた。Further, in the conventional configuration, although the dehumidification at the time of cooling exhibits a sufficient performance, there is a difficulty in temperature control, and the temperature tends to be too cold. Conversely, the dehumidifying capacity during heating is insufficient,
Since it was extremely difficult to prevent dew condensation and mold on the indoor ceiling surface and inner wall surface, improvement in dehumidification performance while maintaining comfort was required.

現化が要求されていた。Therefore, in order to improve the dehumidifying capacity, the refrigerant circulating in the heat pump refrigeration cycle including the refrigerant heat exchanger and the refrigerant connection pipe must be controlled in a complicated manner, resulting in a very high cost. Therefore, realization at low cost has been required.

To reduce noise, increase power consumption, supply fresh outdoor air indoors, efficiently discharge indoor contaminated air to the outdoors in a short time, and form condensation on ceilings and walls. Air that can prevent heating and mildew, maintain the heating capacity without being affected by the outside temperature, improve the heating speed effect, and can be applied to flammable refrigerants relatively inexpensively in consideration of environmental issues. It is intended to provide a harmony device.

温水系サイクル59が構成されている。Next, the hot water cycle 59 will be described. The hot water system heater core 26 in the supply / exhaust wind tunnel device 14 includes an inlet pipe 50, an outlet pipe 51, a water heater 53 as a heat source supply unit, a solar collector 54 as an auxiliary heat source unit, and a heat storage unit.
