【発明の詳細な説明】
この発明は、物質の潜熱を熱源とする冷暖房システムに
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating and cooling system that uses the latent heat of a substance as a heat source.
物質が相変化するとき、熱を発生、または吸収し、温度
が変化しない。従って蓄熱に利用した場合は熱伝導によ
る損失を少くする利点を有する。しかし、その性質は十
分利用されていない。When a substance changes phase, it generates or absorbs heat and its temperature does not change. Therefore, when used for heat storage, it has the advantage of reducing loss due to heat conduction. However, its properties are not fully utilized.
また、ヒートポンプによる冷暖房では、負荷の熱や冷熱
を大気に放熱して無駄であり、その都度作動させなけれ
ばならない欠点があった。In addition, heating and cooling using a heat pump has the disadvantage that heat and cold from the load are radiated into the atmosphere, which is wasteful, and the heat pump must be activated each time.

を行い、省エネルギー化するものである。The present invention utilizes the latent heat of a substance as a heat source by transmitting it to and receiving cold water or hot water of a heating and cooling system via a brine pipe or a brine type heat pump, and at the same time uses the load as a heat source to prepare for the next heating and cooling season. It stores heat for a long time and saves energy.

A brine pipe disposed in the latent heat storage tank l provided underground to exchange heat with water or ice stored in the tank branches into a brine cooling circuit 2a of a brine type heat pump 3, It is connected to the cooling brine pipe 2b disposed in the cold/hot water heat storage tank.

By opening and closing valves v3 and vg of 2b, a closed circuit is constructed in which the brine pump circulates to the left. On the other hand, the condenser 0 of the brine type heat pump 3 is connected to the hot water heating pipe 7 of the cold/hot water heat storage tank.
さらに、冷温水蓄熱槽りには、バルブ■ｊ〜■ざおよび

接続されることはいうまでもない。Furthermore, it goes without saying that a load is connected to the cold/hot water heat storage tank via the cold/hot water piping g including the valves ``j'' to ``■'' and the cold/hot water pump ga.

加熱配管７を介して温水の加熱をし、暖房に使用する。Next, the functions of this system will be explained. First, in the winter season, the brine type heat pump J is operated to remove heat from the liquid, ie, water, in the latent heat storage tank l, heat the hot water via the hot water heating pipe 7, and use it for space heating.

／内を循環し、内部の水を冷却し、やがて氷結させる。More specifically, the wet water is 20°C in the outgoing pipe of the wet water heating pipe 7, but is heated to 23'C by the heat pump 3. On the other hand, evaporator E supplies brine from 0°C to -
, is cooled to 1° C., and circulated through the latent heat storage tank/inside by the brine pump S to cool the water inside and eventually freeze it.
こうして生じた氷はそのまま保存され、夏期には冷却水

槽グ内の冷水を冷却するのである。その際ヒートポンプ
の作動を要さないことはいうまでもない。The resulting ice is then stored and used as cooling water during the summer. That is, in the lt phase, valves V3 and VQ are opened to circulate brine. Then, the ice is melted, and the cold water in the cold/hot water heat storage tank is cooled through the cooling brine pipe 2b. Needless to say, the operation of the heat pump is not required at this time.
これらの動作を下の表に示す。ただし、バルブの場合は
ＯＦＦではバルブ閉を、ＯＮではバルブ開を意味する。These operations are shown in the table below. However, in the case of a valve, OFF means the valve is closed, and ON means the valve is open.
なお、冷夏、暖冬などによる蓄熱量の過不足が生じた場
合を考慮して補助熱源または、大気等への負荷回路を設
けて春・秋に補充運転することもできる。In addition, in consideration of the case where there is an excess or deficiency in the amount of heat storage due to cool summers or warm winters, it is also possible to provide an auxiliary heat source or a load circuit to the atmosphere, etc., and perform supplementary operation in spring and autumn.
以上、本発明は、冷暖房の熱源を潜熱の状態で蓄熱し、
必要に応じて取出すものであるから、熱伝導などによる
熱損失が少く、長期蓄熱も可能とする。そして、潜熱を
負荷に与えれば、逆の冷熱として蓄熱されることとなり
、エネルギーの節約となる。As described above, the present invention stores the heat source of air conditioning and heating in the state of latent heat,
Since it is taken out as needed, there is little heat loss due to heat conduction, etc., and long-term heat storage is possible. If latent heat is given to the load, it will be stored as cold heat, resulting in energy savings.
当に低く、冷水の冷却に適する。Very low, suitable for cooling cold water.
さらに、冬期にはブライン式ヒートポンプにより潜熱を
暖房源とし、これにより生じた固体の融解熱を夏期に使
用すれば、夏期はヒートポンプによらず冷房することが
できる利点を有する。Furthermore, if latent heat is used as a heating source by a brine type heat pump in the winter and the heat of fusion of the solid produced by this is used in the summer, there is an advantage that cooling can be performed in the summer without using the heat pump.
