Description

本発明は，事務所建築物等における空調システムに関するものである。   The present invention relates to an air conditioning system in an office building or the like.

事務所建築物等では冬期においても冷房負荷が発生する。一方、外気取入れの外調機や窓廻りのペリメータでは冬期に暖房負荷が発生する。このような冬期における冷房負荷を賄うために、従来の空調システムでは氷蓄熱槽を設けて安い夜間電力を利用することも多い。   In office buildings, cooling loads are generated even in winter. On the other hand, a heating load is generated in the winter in the outside air intake air conditioner and the perimeter around the window. In order to cover such a cooling load in winter, the conventional air conditioning system often uses an ice heat storage tank and uses cheap night electricity.

図５は氷蓄熱槽を設けた従来の空調システムの一例を示すものである。
図に示すように、この空調システムは、空冷ヒートポンプチラー１０１と水冷式ブラインチラー１０２とから構成しており、夫々のチラー１０１、１０２においてａは圧縮機、ｂは凝縮器、ｃは蒸発器を示すものである。 FIG. 5 shows an example of a conventional air conditioning system provided with an ice heat storage tank.
As shown in the figure, this air conditioning system is composed of an air-cooled heat pump chiller 101 and a water-cooled type blower chiller 102. In each chiller 101, 102, a is a compressor, b is a condenser, and c is an evaporator. It is shown.

空冷ヒートポンプチラー１０１において、蒸発器ｃ側には、矢印１０４で示す給気経路が構成され、空冷ファン１０３を構成している。また凝縮器ｂ側には温水循環系統１０５を構成している。   In the air-cooled heat pump chiller 101, an air supply path indicated by an arrow 104 is configured on the evaporator c side, and an air-cooling fan 103 is configured. A hot water circulation system 105 is formed on the condenser b side.

一方、水冷式ブラインチラー１０２において、蒸発器ｃ側には氷蓄熱槽１０６が構成され、蒸発器ｃから氷蓄熱槽１０６内の熱交換コイル１０７に至るブライン循環系統１０８を構成している。また氷蓄熱槽１０６には冷水循環系統１０９を構成している。一方、凝縮器ｂ側には開放式冷却塔１１０との間の冷却水系統１１１を構成しており、開放式冷却塔１１０にはバイパス制御経路１１２を設けている。尚、図中符号Ｐを付した要素はポンプであり、このポンプの表示は、図１、図２においても同様である。   On the other hand, in the water-cooled blownler 102, an ice heat storage tank 106 is formed on the evaporator c side, and a brine circulation system 108 is formed from the evaporator c to the heat exchange coil 107 in the ice heat storage tank 106. The ice heat storage tank 106 includes a cold water circulation system 109. On the other hand, a cooling water system 111 is formed between the condenser b and the open cooling tower 110, and a bypass control path 112 is provided in the open cooling tower 110. In addition, the element which attached | subjected the code | symbol P in the figure is a pump, and the display of this pump is the same also in FIG. 1, FIG.

以上の構成において、図５は冬期における運転パターンの一例を図中の矢印によって示すもので、空冷ヒートポンプチラー１０１においては、圧縮機ａ、凝縮器ｂ及び蒸発器ｃによる周知のヒートポンプ動作により、凝縮器ｂにおいて温水が生成され、温水循環系統１０５を介して暖房に供されている。   In the above configuration, FIG. 5 shows an example of an operation pattern in winter by arrows in the figure. In the air-cooled heat pump chiller 101, condensation is performed by a well-known heat pump operation using the compressor a, the condenser b, and the evaporator c. Hot water is generated in the vessel b and is supplied to the heating via the hot water circulation system 105.

また、水冷式ブラインチラー１０２においては、夜間の運転により氷結して氷蓄熱槽１０６に蓄えられている氷が溶かされて冷水循環系統１０９を介して冷房に供されている。   Further, in the water-cooled blownler 102, ice that is frozen by night operation and stored in the ice heat storage tank 106 is melted and supplied to the cooling system via the cold water circulation system 109.

図５に示す運転パターンでは、同時に水冷式ブラインチラー１０２の追い掛け運転が行われており、圧縮機ａ、凝縮器ｂ及び蒸発器ｃによる周知のヒートポンプ動作により、蒸発器ｃにおいてブラインが冷却されてブライン循環系統１０８の熱交換コイル１０７により氷蓄熱槽１０６に冷熱が補充される。この追い掛け運転に際して凝縮器ｂに発生する熱は、冷却水系統１１１を介して開放式冷却塔１１０から放熱している。尚、氷蓄熱槽１０６の蓄熱量が十分である場合には、追い掛け運転は不要である。   In the operation pattern shown in FIG. 5, the chasing operation of the water-cooled blownler 102 is performed at the same time, and the brine is cooled in the evaporator c by a known heat pump operation by the compressor a, the condenser b, and the evaporator c. Cold heat is replenished to the ice heat storage tank 106 by the heat exchange coil 107 of the brine circulation system 108. The heat generated in the condenser b during this chasing operation is dissipated from the open cooling tower 110 via the cooling water system 111. If the amount of heat stored in the ice heat storage tank 106 is sufficient, the chasing operation is unnecessary.

そして夜間においては、安い夜間電力により、追い掛け運転と同様なパターンにより、氷蓄熱槽１０６に冷熱が供給されて蓄熱されると共に、凝縮器ｂに発生する熱が開放式冷却塔１１０から放熱される。   In the nighttime, cold energy is supplied to the ice heat storage tank 106 and stored in the same pattern as in the chasing operation at low night power, and heat generated in the condenser b is radiated from the open cooling tower 110. .

以上のように夜間において、安い夜間電力により運転して、氷蓄熱槽に冷熱を蓄熱すると共に、その際に凝縮器に発生する熱を開放式冷却塔から放熱する空調システムは、例えば特許文献１に開示されている。
特開２００３−２７９０７９号公報 As described above, for example, an air conditioning system that operates with cheap nighttime electric power to store cold heat in an ice heat storage tank and dissipates heat generated in a condenser at that time from an open cooling tower is disclosed in Patent Document 1, for example. Is disclosed.
JP 2003-279079 A

以上の従来の空調システムでは、氷蓄熱槽に冷熱を蓄熱するための夜間の運転において発生する熱を開放式冷却塔から放熱してしまい、その有効利用が図られていないという問題点がある。
そこで本発明では、このような問題点を解消し、夜間運転において発生する熱の有効利用を図るという課題を解決することを目的とするものである。 In the above conventional air conditioning system, there is a problem that heat generated in nighttime operation for storing cold heat in the ice heat storage tank is dissipated from the open cooling tower, and its effective use is not achieved.
Therefore, the present invention aims to solve the problem of solving such problems and effectively utilizing heat generated during night driving.

上述した課題を解決するために本発明では，冬期に暖房に供する第１の冷凍機と、冬期に冷房に供する第２の冷凍機を構成し、第２の冷凍機には蒸発器側に第１の蓄熱槽を構成すると共に凝縮器側に第２の蓄熱槽を構成し、また第１の冷凍機の蒸発器側には第２の蓄熱槽に蓄熱された熱により加温した温水を供給する熱交換器を構成した空調システムを提案する。   In order to solve the above-described problems, the present invention includes a first refrigerator that is used for heating in winter and a second refrigerator that is used for cooling in winter, and the second refrigerator has a second refrigerator on the evaporator side. 1 heat storage tank and a second heat storage tank on the condenser side, and hot water heated by heat stored in the second heat storage tank is supplied to the evaporator side of the first refrigerator. We propose an air conditioning system with a heat exchanger.

そして本発明では、上記の構成において、第１の蓄熱槽が氷蓄熱槽であり、第２の蓄熱槽が潜熱蓄熱槽である空調システムを提案する。   And in this invention, in said structure, a 1st heat storage tank is an ice heat storage tank, and the 2nd heat storage tank proposes the air-conditioning system which is a latent heat storage tank.

また本発明では、以上の構成において、第１の冷凍機が空冷ヒートポンプチラーであると共に第２の冷凍機が水冷式ブラインチラーであり、第１の冷凍機の給気経路の蒸発器の上流側に第２の蓄熱槽に蓄熱された熱を利用する熱交換器を構成した空調システムを提案する。そして本発明では、この構成において、給気経路には、熱交換器をバイパスするバイパスダンパーを構成した空調システムを提案する。   In the present invention, in the above configuration, the first refrigerator is an air-cooled heat pump chiller and the second refrigerator is a water-cooled blown-chiller, upstream of the evaporator in the air supply path of the first refrigerator. The air-conditioning system which constituted the heat exchanger using the heat stored in the 2nd heat storage tank is proposed. And in this invention, in this structure, the air-conditioning system which comprised the bypass damper which bypasses a heat exchanger in an air supply path | route is proposed.

また本発明では、上記の構成において、第２の蓄熱槽に蓄熱された熱により加温した温水を供給する熱交換器を第１の冷凍機の蒸発器に構成した空調システムを提案する。   The present invention also proposes an air conditioning system in which, in the above-described configuration, a heat exchanger that supplies warm water heated by heat stored in the second heat storage tank is configured as an evaporator of the first refrigerator.

本発明の空調システムでは、第２の冷凍機の運転により蒸発器側の第１の蓄熱槽に冷熱を蓄熱する際に、凝縮器側で発生する熱を第２の蓄熱槽に蓄え、この蓄えた熱を、第１の冷凍機の運転により暖房を行う際に、その蒸発器に供給することにより、従来放熱されていた熱の有効利用を図ることができる。   In the air conditioning system of the present invention, when cold heat is stored in the first heat storage tank on the evaporator side by operating the second refrigerator, the heat generated on the condenser side is stored in the second heat storage tank, and this storage is performed. By supplying the heat to the evaporator when heating is performed by operating the first refrigerator, it is possible to effectively use heat that has been radiated.

第１の蓄熱槽は、従来と同様に氷蓄熱槽により構成することができ、また第２の蓄熱槽は潜熱蓄熱槽により構成することができる。   The 1st heat storage tank can be comprised with an ice heat storage tank similarly to the past, and the 2nd heat storage tank can be comprised with a latent heat storage tank.

第１の冷凍機は空冷ヒートポンプチラーとして構成することができ、この場合には、第２の蓄熱槽から蒸発器への熱の供給は、第２の蓄熱槽からの温水を供給する熱交換器を蒸発器の給気経路の上流側に構成して行うことができる。またこの構成では、給気経路に熱交換器をバイパスするバイパスダンパーを設ければ、熱交換器を使用しない場合における通風抵抗を低減することができる。   The first refrigerator can be configured as an air-cooled heat pump chiller. In this case, the heat supply from the second heat storage tank to the evaporator is a heat exchanger that supplies hot water from the second heat storage tank. Can be performed on the upstream side of the air supply path of the evaporator. Further, in this configuration, if a bypass damper that bypasses the heat exchanger is provided in the air supply path, the ventilation resistance when the heat exchanger is not used can be reduced.

また第１の冷凍機の蒸発器への第２の蓄熱槽の熱の供給は、第２の蓄熱槽に蓄熱された熱により加温した温水を供給する熱交換器を第１の冷凍機の蒸発器に構成して行うこともでき、この場合には、第１の冷凍機は、水冷の水熱源方式のヒートポンプチラーとして構成することができる。   In addition, the heat supply of the second heat storage tank to the evaporator of the first refrigerator is performed by using a heat exchanger that supplies hot water heated by the heat stored in the second heat storage tank of the first refrigerator. In this case, the first refrigerator can be configured as a water-cooled water heat source type heat pump chiller.

次に，本発明に係る空調システムの実施の形態を添付図面を参照して説明すると、まず図１、図２は本発明の空調システムの第１の実施の形態を示す系統図であり、図１は夜間における蓄熱運転、図２は昼間における空調運転を、矢印により示すものである。   Next, an embodiment of an air conditioning system according to the present invention will be described with reference to the accompanying drawings. First, FIG. 1 and FIG. 2 are system diagrams showing the first embodiment of the air conditioning system of the present invention. Reference numeral 1 denotes a heat storage operation at night, and FIG. 2 shows an air conditioning operation at daytime by arrows.

この実施の形態の空調システムは、概ね、第１の冷凍機である空冷ヒートポンプチラー１と、第２の冷凍機である水冷式ブラインチラー２とから構成され、図５と同様に、夫々のチラー１、２においてａは圧縮機、ｂは凝縮器、ｃは蒸発器を示すものである。   The air conditioning system of this embodiment is generally composed of an air-cooled heat pump chiller 1 that is a first refrigerator and a water-cooled blown-chiller 2 that is a second refrigerator, and each chiller is similar to FIG. 1 and 2, a is a compressor, b is a condenser, and c is an evaporator.

空冷ヒートポンプチラー１において、蒸発器ｃ側の給気経路３には、熱交換器４が構成されており、給気ファン５によって外気から取り入れられた空気は、この熱交換器４を通過した後に蒸発器ｃに供給される。また凝縮器ｂ側には温水循環系統６が構成され、この温水循環系統６を介して暖房を行う構成としている。   In the air-cooled heat pump chiller 1, a heat exchanger 4 is configured in the air supply path 3 on the evaporator c side, and the air taken in from the outside air by the air supply fan 5 passes through the heat exchanger 4. It is supplied to the evaporator c. Further, a hot water circulation system 6 is configured on the condenser b side, and heating is performed via the hot water circulation system 6.

一方、水冷式ブラインチラー２において、蒸発器ｃ側には、第１の蓄熱槽としての氷蓄熱槽７が構成され、蒸発器ｃから氷蓄熱槽７内の熱交換コイル８に至るブライン循環系統９を構成している。また氷蓄熱槽７には冷水循環系統１０を構成しており、この冷水循環系統１０を介して冷房を行う構成としている。   On the other hand, in the water-cooled blownler 2, an ice heat storage tank 7 as a first heat storage tank is configured on the evaporator c side, and a brine circulation system extending from the evaporator c to the heat exchange coil 8 in the ice heat storage tank 7. 9 is constituted. In addition, the ice heat storage tank 7 is configured with a cold water circulation system 10 and is configured to perform cooling through the cold water circulation system 10.

また水冷式ブラインチラー２の凝縮器ｂ側には、第２の蓄熱槽としての潜熱蓄熱槽１１が構成されており、この潜熱蓄熱槽１１は、潜熱蓄熱材１２を入れた温水槽として構成しており、上記熱交換器４との間の温水循環系統１３と、第２の冷凍機２の凝縮器ｂとの間の冷却水循環系統１４を構成している。そしてこの実施の形態では、冷却水循環系統１４には開放式冷却塔１５に至る放熱系統１７を構成しており、冷却水循環系統１４に流れる温水を、放熱系統１７にも流す運転と、放熱系統１７には流さない運転とに切換弁１７により切換可能としている。   Further, a latent heat storage tank 11 as a second heat storage tank is configured on the condenser b side of the water-cooled branler 2, and the latent heat storage tank 11 is configured as a hot water tank containing a latent heat storage material 12. And constitutes a cooling water circulation system 14 between the hot water circulation system 13 between the heat exchanger 4 and the condenser b of the second refrigerator 2. In this embodiment, the cooling water circulation system 14 is configured with a heat radiation system 17 that reaches the open cooling tower 15, and the operation for flowing the hot water flowing through the cooling water circulation system 14 to the heat radiation system 17 is also performed. The operation can be switched by the switching valve 17 so that the operation is not performed.

以上の構成において、夜間の蓄熱運転は、図１に示すように水冷式ブラインチラー２を運転して行う。この夜間の蓄熱運転では、蒸発器ｃに発生する冷熱は、ブライン循環系統９を流れるブラインを介して熱交換コイル８から氷蓄熱槽７内の水に供給され、氷結により蓄熱される。一方、凝縮器ｂに発生する熱は冷却水循環系統１４を流れる温水を介して潜熱蓄熱槽１１内の潜熱蓄熱材１２に供給され、相転移により蓄熱される。   In the above configuration, the nighttime heat storage operation is performed by operating the water-cooled blownler 2 as shown in FIG. In this nighttime heat storage operation, the cold heat generated in the evaporator c is supplied from the heat exchange coil 8 to the water in the ice heat storage tank 7 through the brine flowing through the brine circulation system 9, and is stored by freezing. On the other hand, the heat generated in the condenser b is supplied to the latent heat storage material 12 in the latent heat storage tank 11 via hot water flowing through the cooling water circulation system 14 and is stored by phase transition.

次に冬期における昼間の空調運転では、図２に示すように空冷ヒートポンプチラー１の運転により凝縮器ｂに発生した熱が温水循環系統６に流れる温水に供給されて暖房が行われると共に、氷蓄熱槽７の冷水循環系統１０が運転されて、氷蓄熱槽７に蓄えられている氷が溶かされ、その冷熱が冷水循環系統１０を流れる冷水に供給され、この冷水により冷房が行われる。更に、この運転においては、温水循環系統１３が運転され、潜熱蓄熱槽１１内の潜熱蓄熱材１２に蓄えられている熱が温水循環系統１３を流れる温水に供給される。そしてこの温水は、温水循環系統１３により熱交換器４において放熱し、給気経路３を流れる空気を昇温して蒸発器ｃに熱を供給する。   Next, in the daytime air conditioning operation in winter, as shown in FIG. 2, the heat generated in the condenser b by the operation of the air-cooled heat pump chiller 1 is supplied to the hot water flowing through the hot water circulation system 6 to perform heating, and ice storage The cold water circulation system 10 of the tank 7 is operated, the ice stored in the ice heat storage tank 7 is melted, the cold heat is supplied to the cold water flowing through the cold water circulation system 10, and cooling is performed by this cold water. Further, in this operation, the hot water circulation system 13 is operated, and the heat stored in the latent heat storage material 12 in the latent heat storage tank 11 is supplied to the hot water flowing through the hot water circulation system 13. This hot water is radiated in the heat exchanger 4 by the hot water circulation system 13, and the temperature of the air flowing through the air supply path 3 is raised to supply heat to the evaporator c.

こうして夜間の蓄熱運転において潜熱蓄熱槽１１内の潜熱蓄熱材１２に蓄えられた熱が、空冷ヒートポンプチラー１の暖房運転における蒸発器ｃに供給されて有効利用がなされる。   Thus, the heat stored in the latent heat storage material 12 in the latent heat storage tank 11 in the night heat storage operation is supplied to the evaporator c in the heating operation of the air-cooled heat pump chiller 1 for effective use.

一方、冷水循環系統１０による冷房運転において、冷房負荷が大きくて、氷蓄熱槽７内の氷の溶ける量が多い場合には、図２に示すように、水冷式ブラインチラー２の追い掛け運転を行って氷蓄熱槽７に冷熱を補充する。   On the other hand, in the cooling operation by the chilled water circulation system 10, when the cooling load is large and the amount of ice melted in the ice heat storage tank 7 is large, the chasing operation of the water-cooled blownler 2 is performed as shown in FIG. The ice storage tank 7 is replenished with cold heat.

この追い掛け運転において凝縮器ｂに発生する熱は、夜間の蓄熱運転と同様に冷却水循環系統１４を流れる温水を介して潜熱蓄熱槽１１内の潜熱蓄熱材１２に供給されて蓄熱される。   The heat generated in the condenser b in this chasing operation is supplied to the latent heat storage material 12 in the latent heat storage tank 11 through hot water flowing through the cooling water circulation system 14 and stored there in the same manner as the nighttime heat storage operation.

尚、上述した冬期における夜間の蓄熱運転又は昼間の追い掛け運転において、潜熱蓄熱槽１１内の潜熱蓄熱材１２に十分な蓄熱がされる等により、凝縮器ｂの冷却が十分に行えない場合には、切換弁１７を操作して、冷却水循環系統１４の水を放熱系統１６を介して開放式冷却塔１５を通過させて冷却し、しかる後に凝縮器ｂに供給することにより、凝縮器ｂの冷却を良好に行うことができる。   In the above-described winter heat storage operation in the nighttime or daytime chasing operation, when the condenser b cannot be sufficiently cooled due to sufficient heat storage in the latent heat storage material 12 in the latent heat storage tank 11 or the like. The condenser b is cooled by operating the switching valve 17 to cool the water in the cooling water circulation system 14 through the heat radiation system 16 through the open cooling tower 15 and then supplying the cooling water to the condenser b. Can be performed satisfactorily.

次に図３は本発明の空調システムの第２の実施の形態を示す要部説明図であり、この実施の形態は、第１の冷凍機１、この場合には第１の実施の形態と同様に空冷ヒートポンプチラー１の蒸発器ｃの給気経路３に、熱交換器４をバイパスするバイパスダンパー１８を構成したものである。その他の構成は、第１の実施の形態と同様であるので、その構成要素と対応する構成要素には同一の符号を付して、重複する説明は省略する。   Next, FIG. 3 is a main part explanatory view showing a second embodiment of the air conditioning system of the present invention. This embodiment is the same as the first refrigerator 1, in this case, the first embodiment. Similarly, a bypass damper 18 that bypasses the heat exchanger 4 is configured in the air supply path 3 of the evaporator c of the air-cooled heat pump chiller 1. Since the other configuration is the same as that of the first embodiment, the components corresponding to the components are denoted by the same reference numerals, and redundant description is omitted.

この実施の形態では、潜熱蓄熱槽１１からの供給熱量が不足する場合には、給気ファン５からの空気は、熱交換器４を通さずにバイパスダンパー１８を通すことにより、通風抵抗を低減することができ、また熱交換器４が使用できる場合には、バイパスダンパー１８を閉とすることにより空気を熱交換器４に確実に通過させることができる。   In this embodiment, when the amount of heat supplied from the latent heat storage tank 11 is insufficient, the air from the air supply fan 5 passes through the bypass damper 18 without passing through the heat exchanger 4, thereby reducing the ventilation resistance. When the heat exchanger 4 can be used, the air can be surely passed through the heat exchanger 4 by closing the bypass damper 18.

次に図４は本発明の空調システムの第３の実施の形態を示す要部説明図であり、この実施の形態は、例えば第１の実施の形態における熱交換器４の機能を、蒸発器ｃ内に構成した熱交換器１９によって行うようにしたものである。その他の構成は、第１の実施の形態と同様であるので、その構成要素と対応する構成要素には同一の符号を付して、重複する説明は省略する。   Next, FIG. 4 is a main part explanatory view showing a third embodiment of the air-conditioning system of the present invention. In this embodiment, for example, the function of the heat exchanger 4 in the first embodiment is changed to an evaporator. This is performed by the heat exchanger 19 configured in c. Since the other configuration is the same as that of the first embodiment, the components corresponding to the components are denoted by the same reference numerals, and redundant description is omitted.

この実施の形態では、第１の冷凍機１は、空冷ヒートポンプチラーに替えて、水冷の水熱源方式のヒートポンプチラーとして構成することができる。   In this embodiment, the first refrigerator 1 can be configured as a water-cooled water heat source type heat pump chiller instead of the air-cooled heat pump chiller.

以上の実施の形態においては、第１の冷凍機１と第２の冷凍機２のいずれも、圧縮機を構成要素とする圧縮式冷凍機としているが、その他、吸収式冷凍機を第１の冷凍機又は第２の冷凍機として使用することもできる。   In the above embodiment, both the first refrigerator 1 and the second refrigerator 2 are compression refrigerators having a compressor as a constituent element, but in addition, the absorption refrigerator is the first refrigerator. It can also be used as a refrigerator or a second refrigerator.

尚、第２の蓄熱槽を潜熱蓄熱槽とした場合の、潜熱蓄熱材１２の相転移温度は、第２の冷凍機の凝縮器において発生するよりも低く、且つ、第１の冷凍機の蒸発器に供給される空気の温度よりも高ければ良いので、従来から実用化されている無機水和塩系や有機化合物系の潜熱蓄熱材を利用することができ、その温度自体では直接的に暖房に利用できない場合にも有効に暖房に利用することができる。   When the second heat storage tank is a latent heat storage tank, the phase transition temperature of the latent heat storage material 12 is lower than that generated in the condenser of the second refrigerator, and the first refrigerator is evaporated. As long as it is higher than the temperature of the air supplied to the vessel, it is possible to use inorganic hydrate salt-based or organic compound-based latent heat storage materials that have been put into practical use. It can be effectively used for heating even when it cannot be used.

本発明の空調システムは、以上のとおり，冬期において暖房負荷に加えて、冷房負荷に対応させるために氷蓄熱槽等の蓄熱槽を有する空調システムにおいて、氷蓄熱槽に冷熱を蓄熱するための夜間の運転において発生する熱を開放式冷却塔から放熱せずに蓄熱し、これを昼間の暖房運転に有効利用することができるという格別な効果があり、産業上の利用可能性が大である。   As described above, the air-conditioning system of the present invention has a heat storage tank such as an ice heat storage tank in order to cope with a cooling load in addition to a heating load in winter. The heat generated in this operation can be stored without dissipating heat from the open cooling tower, and this can be effectively used for daytime heating operation, and industrial applicability is great.
