This air conditioning system includes ambient air conditioning that conservatively air-conditions the entire room 10 and a task that locally air-conditions the vicinity of the work place 12 in the room 10. Air conditioning is performed.
アンビエント空調は、図示せぬが、一般的な空調方式を用いたアンビエント専用の空調機を用いて、例えば、空調エアを床吹出し、天井吸込み方式で空調するようになっている。 Ambient air conditioning is not shown, but using an ambient air conditioner using a general air conditioning system, for example, air conditioning air is blown to the floor and air is conditioned by a ceiling suction system.
なお、天井には吸込み口８が設けられている。 A suction port 8 is provided on the ceiling.
タスク空調は、局部的空調を行う作業部所１２において作業者の上半身及び下半身付近に吹出し口１４、１６を配設し、これら吹出し口１４，１６に至る空調エアの吹出し経路の途中に潜熱蓄熱材を配設するようにしている。 In the task air conditioning, air outlets 14 and 16 are arranged in the vicinity of the upper body and lower body of the worker in the work section 12 that performs local air conditioning, and latent heat storage is performed in the middle of the air-conditioning air blowing path leading to the air outlets 14 and 16. The material is arranged.
具体的には、熱源機１８からの冷温水を冷温水管２０及び電動弁２２を介してタスク用の空調機２４に供給し、空調機２４より二重床２６を通して二重床２６上に空調エアを供給するようにしている。 Specifically, the cold / hot water from the heat source device 18 is supplied to the task air conditioner 24 via the cold / hot water pipe 20 and the electric valve 22, and the air-conditioning air is supplied from the air conditioner 24 to the double floor 26 through the double floor 26.

さらに、パネル３０内には、その上部及び下部に複数の潜熱蓄熱材３６及び３８が配設されるようになっている。 Furthermore, a plurality of latent heat storage materials 36 and 38 are disposed in the upper portion and the lower portion of the panel 30.
これらの潜熱蓄熱材３６、３８としては、例えば、高い融解潜熱を有する石油系のノルマルパラフィンを原料とし、それをゲル状に加工したもので、氷より高い特定の温度（３〜３０℃）で「凝固、融解」の相変化を繰り返すものを採用することができる。 As these latent heat storage materials 36 and 38, for example, petroleum-based normal paraffin having a high latent heat of fusion is used as a raw material, which is processed into a gel, and at a specific temperature (3 to 30 ° C.) higher than ice.

By blowing out air, the latent heat storage materials 36 and 38 can be used for task air conditioning, and efficient energy saving can be achieved with good responsiveness.
また、夏期に潜熱蓄熱材３６、３８を利用して一日の電力需要を抑えたいピークカット時間に送風モードとして使用することで電力需要を抑えることができる。 Moreover, electric power demand can be suppressed by using it as a ventilation mode in the peak cut time which wants to suppress the electric power demand of one day using the latent heat storage materials 36 and 38 in summer.
さらに、潜熱蓄熱材３６、３８をパネル３０内に配設することで、机２８の上部や下部に容易に設置可能にするとともに、パネルの前面位置に吹出し口を形成することで、応答性の良い空調効果を得ることができる。 Furthermore, by arranging the latent heat storage materials 36 and 38 in the panel 30, it can be easily installed on the upper and lower parts of the desk 28, and a responsiveness can be obtained by forming a blowout port at the front position of the panel. A good air conditioning effect can be obtained.
また、机２８の上部側のパネル３０内の潜熱蓄熱材３６を冷房用の凝固点に設定し、机２８の下部側のパネル３０内の潜熱蓄熱材３８を暖房用の凝固点に設定することで、机２８の上部から冷風を、下部から暖風を供給して効率の良い局所的空調を行うことができる。 Further, by setting the latent heat storage material 36 in the panel 30 on the upper side of the desk 28 as a freezing point for cooling, and setting the latent heat storage material 38 in the panel 30 on the lower side of the desk 28 as a freezing point for heating, Efficient local air conditioning can be performed by supplying cool air from the upper part of the desk 28 and warm air from the lower part.
また、前記実施の形態では、タスク・アンビエント空調において、潜熱蓄熱材を用いたタスク空調を行う場合について説明したが、この例に限らず、アンビエント空調を行わず、図１及び図２に示すような潜熱蓄熱材３６、３８を組み込んだパネル３０を用いたタスク空調を行うようにし、少なくとも、作業部所の作業者の上半身及び下半身付近の少なくとも１か所に吹出し口を配設し、前記吹出し口に至る空調エアの吹出し経路の途中に潜熱
蓄熱材を配設した空調システムとすることが可能である。

これらの潜熱蓄熱材３６、３８は、異なる凝固点に設定されており、一方の潜熱蓄熱材３６は、冷房用の潜熱蓄熱材となっており、例えば２０℃以下で凝固するものを用い、夏期に冷房で凝固させた潜熱蓄熱材を冷房から送風モードに切り替えることで所定時間（例
えば、１〜２時間）の冷房をカットすることができるようになっている。
These latent heat storage materials 36 and 38 are set at different freezing points, and one of the latent heat storage materials 36 is a latent heat storage material for cooling. For example, a material that solidifies at 20 ° C. or less is used in summer. The cooling for a predetermined time (for example, 1 to 2 hours) can be cut by switching the latent heat storage material solidified by cooling from the cooling to the air blowing mode.
他方の潜熱蓄熱材３８は、暖房用の潜熱蓄熱材となっており、例えば３０℃以下で凝固するものを用い、冬期の空調立ち上がり時に送風モードで所定時間足元に暖かい空気を供給することができるようになっている。 The other latent heat storage material 38 is a latent heat storage material for heating. For example, a material that solidifies at 30 ° C. or lower can be used, and warm air can be supplied for a predetermined time in a blowing mode at the start of air conditioning in winter. It is like that.
そしてこれらの吹出し口５２、５４を各吹出し口５２、５４に設けられた風向、風量及び開閉制御可能なグリル４１によって切り替えることで、冷房と暖房を切り替えるようになっている。 These air outlets 52 and 54 are switched by the grille 41 provided at the air outlets 52 and 54 so that the air direction, the air volume, and the opening and closing can be controlled, thereby switching between cooling and heating.
また、室内１０に供給された空調エアは、天井５６に設けられた吸込み口６０より天井５６の裏に配したレターンダクト６４を通して空調機２４に戻されるようになっている。 The air-conditioning air supplied to the room 10 is returned to the air conditioner 24 through a return duct 64 disposed on the back of the ceiling 56 from a suction port 60 provided in the ceiling 56.
他の構成及び作用は、前述の図１及び図２の実施の形態と同様につき、同様の部分には同一符号を付すにとどめ、説明を省略する。 Other configurations and operations are the same as those in the embodiment shown in FIGS. 1 and 2 described above, and the same parts are denoted by the same reference numerals, and description thereof is omitted.
前記図１〜図４の実施の形態では、潜熱蓄熱部材を組み込んだパネルを用いる空調システムについて説明したが、この例に限らず、パネルを用いることなく、潜熱蓄熱材を吹出し口へと空調エアを供給するダクト内に配設することで、潜熱蓄熱材設置のための格別のスペースを要することなく、応答性の良い、効率的な省エネルギー化を図ることができるものとすることも可能である。 In the embodiment shown in FIGS. 1 to 4, the air conditioning system using the panel incorporating the latent heat storage member has been described. However, the present invention is not limited to this example, and the latent heat storage material is supplied to the outlet through the air conditioning air without using the panel. It is also possible to achieve responsive and efficient energy saving without requiring a special space for installing the latent heat storage material. .
また、前記図１〜図４の実施の形態では、潜熱蓄熱材を組み込んだ１枚または２枚のパネルを机の上部及び下部に配置し、吹出し口を作業者の上半身付近及び下半身付近の双方に設ける場合について説明したが、パネルを机の上部または下部の一方、吹出し口を作業者の上半身付近または下半身付近の一方に設けるようにすることも可能である。 In the embodiment shown in FIGS. 1 to 4, one or two panels incorporating the latent heat storage material are arranged at the upper and lower parts of the desk, and the outlets are located near both the upper body and the lower body of the worker. However, it is also possible to provide the panel at one of the upper part and the lower part of the desk and the air outlet near one of the upper body and the lower body of the operator.
