Description

本発明は、新規な揮発性二次冷媒冷・温熱出力方式を適用する吸収式冷温機に関するものである。   The present invention relates to an absorption chiller to which a novel volatile secondary refrigerant cooling / heating output system is applied.

従来の吸収式冷温水機の循環冷温水による冷・温熱出力方法と装置を説明するため、従来の単効用臭化リチウム／水系吸収冷温水機を例にして図４に示す。
図示のように従来の臭化リチウム／水系吸収冷温水機に関しては、冷熱出力モードでは、循環冷水を循環冷温水ポンプ２０により蒸発器１の伝熱管１ａＡ内に導入し、また凝縮器１Ａからの冷媒凝縮液を蒸発器１内に導入し、また冷媒液ポンプ３により、蒸発器１底部の循環冷媒液を循環して、冷媒液散布装置１ａにより蒸発器１の伝熱管１ａＡ外壁面に散布し、その蒸発吸熱により蒸発器１の伝熱管１ａＡ内の循環冷水を冷却し、次にこの様に温度が下がった循環冷水を空調機４の伝熱管４ａに送り、そこで送風される空調用空気を冷やして冷熱出力がなされる。
また温熱発生モードでは、循環温水を循環冷温水ポンプ２０により蒸発器１の伝熱管１ａＡ内に導入し、また熱源１ｇを有すると共に、溶液熱交換器１ｈを介して希吸収液ポンプ１ｆに接続された再生器１Ｃからの高温冷媒蒸気を暖房用冷媒蒸気通路１Ｄを介して直接に蒸発器１にバイパスさせ、これにより蒸発器１の伝熱管１ａＡ内に流される循環温水を加熱して、次にこの様に温度が上がった循環温水を空調機４の伝熱管４ａ内に送り、そこで送風される空調用空気を温めて温熱出力がなされる。
また図示のように循環冷温水パイプライン２１に冷温水補給のための膨張タンク２２が取り付けられている。 FIG. 4 shows an example of a conventional single-effect lithium bromide / water-based absorption chiller / heater in order to describe a cooling / heat output method and apparatus using circulating chilled / hot water of a conventional absorption chiller / heater.
As shown in the figure, in the conventional lithium bromide / water absorption chiller / heater, in the heat output mode, the chilled water is introduced into the heat transfer tube 1aA of the evaporator 1 by the circulatory chilled / hot water pump 20, and from the condenser 1A. The refrigerant condensate is introduced into the evaporator 1, and the refrigerant liquid pump 3 circulates the circulating refrigerant liquid at the bottom of the evaporator 1, and the refrigerant liquid spraying device 1a sprays it on the outer wall surface of the heat transfer tube 1aA of the evaporator 1. Then, the circulating cold water in the heat transfer tube 1aA of the evaporator 1 is cooled by the evaporation heat absorption, and then the circulating cold water whose temperature has been lowered in this way is sent to the heat transfer tube 4a of the air conditioner 4, and the air conditioning air blown there is Cooling and cold output are made.
In the heat generation mode, the circulating hot water is introduced into the heat transfer pipe 1aA of the evaporator 1 by the circulating cold / hot water pump 20, and has a heat source 1g and is connected to the diluted absorbent pump 1f via the solution heat exchanger 1h. The high-temperature refrigerant vapor from the regenerator 1C is bypassed directly to the evaporator 1 via the heating refrigerant vapor passage 1D, thereby heating the circulating hot water flowing into the heat transfer pipe 1aA of the evaporator 1, The circulating hot water whose temperature has increased in this way is sent into the heat transfer pipe 4a of the air conditioner 4, and the air-conditioning air blown there is warmed to produce a thermal output.
Further, as shown in the figure, an expansion tank 22 for replenishing cold / hot water is attached to the circulating cold / hot water pipeline 21.

前述の様な従来型の吸収冷温水機は、以下のような課題が存在していた。
すなわち、冷熱出力モードでは循環冷水を蒸発器部で冷却されてこの様に温度が下がった循環冷水を空調機に送り、そこで空調用空気を冷やして冷熱出力をなされる。また温熱出力モードでは再生器から高温冷媒蒸気を蒸発器部に導入し、前記蒸発器伝熱管内に流される循環温水を加熱し、この様に温度が上がった循環温水を空調機に送り、そこで前記空調機伝熱管間に送風される空調用空気を温めて温熱出力がなされるのである。
この様にして循環冷温水の顕熱変化を利用して冷温熱出力をなされるため、所要循環冷温水量は多く、所要循環冷温水輸送動力が大きい。また循環冷温水側の局部熱伝達係数がさほど大きくないため、所要蒸発器と空調機サイズは比較的大きく、所要材料は多い。また循環冷温水装置は常に水が補給され、循環冷温水流路が密閉式でないため、蒸発器伝熱管を定期的に清掃する必要があった。
また冷熱出力のモードの場合、蒸発器部冷熱出力温度または冷熱発生温度は直接に吸収式冷温機の冷熱出力成績係数に影響を及ぼしており、二重効用吸収冷凍機または吸収冷温水機の場合には、循環冷水温度が１℃上がると成績係数が６〜７％で上がり、循環冷水温度の影響を大きく受けていた。 The conventional absorption chiller / heater as described above has the following problems.
In other words, in the cold power output mode, the circulating cold water is cooled by the evaporator section, and the circulating cold water whose temperature has been lowered in this way is sent to the air conditioner, where the air conditioning air is cooled to produce cold output. In the thermal output mode, high-temperature refrigerant vapor is introduced from the regenerator into the evaporator section, the circulating hot water flowing into the evaporator heat transfer pipe is heated, and the circulating hot water thus heated is sent to the air conditioner. Air conditioning air blown between the air conditioner heat transfer tubes is warmed to produce a warm output.
In this way, since the cooling / heating output is made using the sensible heat change of the circulating cold / hot water, the required circulating cold / hot water amount is large and the required circulating cold / hot water transport power is large. In addition, since the local heat transfer coefficient on the circulating cold / hot water side is not so large, the required evaporator and air conditioner sizes are relatively large, and there are many required materials. Further, since the circulating chilled / hot water device is always replenished with water and the circulating chilled / hot water flow path is not hermetically sealed, it has been necessary to periodically clean the evaporator heat transfer tubes.
In the case of the cold power output mode, the evaporator heat output temperature or the heat generation temperature directly affects the cooling output coefficient of performance of the absorption chiller. In the case of a double-effect absorption chiller or absorption chiller / heater When the circulating chilled water temperature increased by 1 ° C., the coefficient of performance increased by 6 to 7%, which was greatly influenced by the circulating chilled water temperature.

本発明による吸収冷温機の冷・温熱出力方法及び装置は、以上のように構成されているため、次のような効果を得ることができる。
すなわち、揮発性二次冷媒の凝縮及び蒸発潜熱を利用して冷温熱出力がなされるため、冷熱出力モードでは、蒸発器部の冷熱発生温度を合理的に高く設定でき、これにより最高再生温度の低下と成績係数の向上が図られる。
また、最高再生温度の低下により、熱源流体をより低温または低品位まで利用でき、熱源の熱エネルギー利用効率の向上が図られる。
また、冷温熱出力モードの両方には、同一のコンパクトな蒸発器と空調機を適用するため、装置全体のサイズが低減、省材料が図れる。また、所要循環揮発性二次冷媒動力は極小さく、省エネの効果が顕著である。さらに、揮発性二次冷媒流路が密閉であり、通常揮発性二次冷媒補給が不要なので、蒸発器と空調機の伝熱管内の定期的清掃は不要となる。 Since the cooling / heating output method and apparatus of the absorption chiller according to the present invention are configured as described above, the following effects can be obtained.
That is, since the cold heat output is made by using the condensation and latent heat of evaporation of the volatile secondary refrigerant, in the cold heat output mode, the cold heat generation temperature of the evaporator section can be set to a reasonably high temperature, thereby achieving the maximum regeneration temperature. Reduction and improvement in coefficient of performance are achieved.
Further, due to the decrease in the maximum regeneration temperature, the heat source fluid can be used at a lower temperature or lower quality, and the heat energy utilization efficiency of the heat source can be improved.
In addition, since the same compact evaporator and air conditioner are applied to both the cool / heat output modes, the overall size of the apparatus can be reduced and material saving can be achieved. Further, the required circulating volatile secondary refrigerant power is extremely small, and the energy saving effect is remarkable. Furthermore, since the volatile secondary refrigerant flow path is hermetically sealed, and volatile secondary refrigerant replenishment is usually unnecessary, periodic cleaning of the evaporator and the heat transfer tubes of the air conditioner is not necessary.

Due to the generated cold heat, the air for air conditioning blown out of the heat transfer tube 4a of the air conditioner 4 is cooled to produce a cold output. Further, volatile secondary refrigerant vapor from the air conditioner 4 is caused to flow into the evaporator 1 due to a pressure difference, and refrigerant condensate from a condenser 1A (not shown) is introduced into the evaporator 1, and at the same time, the evaporator The refrigerant liquid is circulated by the partial circulation refrigerant liquid pump 1b, and is dispersed by the refrigerant liquid spraying device 1a on the outer wall surface of the heat transfer pipe 1aA of the evaporator 1, and the evaporator 1 The refrigerant vapor flowing into the heat transfer tube 1aA is condensed, and the refrigerant condensate thus formed is introduced into the receiver 2 through the first and second three-way valves 5 and 6, and temporarily accumulates there.

従って、前述の本発明の構成により、以下の作用を得ることができる。
その１、冷・温熱両出力モードでは、蒸発器１と空調機４での熱交換での冷媒と揮発性二次冷媒の潜熱を利用するため、冷媒と揮発性二次冷媒蒸気との両側の局部熱伝達係数が大きく、前記蒸発器１と空調機４の熱交換器のコンパクト化と省材料が図れる。
その２、冷・温熱両出力モードでは、同一の蒸発器１と空調機４を利用できるため、装置の簡素化が図れる。
その３、冷熱出力モードでは、揮発性二次冷媒の潜熱を利用して冷熱出力がなされるため、循環揮発性二次冷媒の圧損によるその温度変化を小さく抑えられるように蒸発器１と空調機４を設計することにより、冷熱出力時に蒸発器１の冷熱発生温度を適切に高く設定できる。また冷媒蒸気と吸収液との気液平衡関係により、吸収器部吸収操作温度の一定な条件下において再生済吸収液の濃度を低く設定でき、これにより再生器部の吸収液再生操作温度または多重効用の場合の最高再生温度を低く設定でき、熱源流体をより低温または低品位まで利用できることにより、熱源の熱エネルギー利用効率の向上が図れる。
その４、再生済吸収液濃度を低く設定できることにより、吸収液の結晶現象による運転支障発生の可能性は低くなるかあるいは無くなる。
その５、循環冷温水の冷・温熱出力時に比較的大きい循環水動力の代わりに、所要循環二次冷媒動力は極小さく、省エネの効果が顕著である。
その６、蒸発器１の熱交換器の伝熱管１ａＡ内の定期的清掃は不要である。 Therefore, the following effects can be obtained by the configuration of the present invention described above.

The local heat transfer coefficient is large, and the heat exchangers of the evaporator 1 and the air conditioner 4 can be made compact and save materials.
Second, in both the cold and hot output modes, the same evaporator 1 and air conditioner 4 can be used, so that the apparatus can be simplified.
Third, in the cold heat output mode, since the cold heat output is made by using the latent heat of the volatile secondary refrigerant, the evaporator 1 and the air conditioner can suppress the temperature change due to the pressure loss of the circulating volatile secondary refrigerant. By designing 4, the cold heat generation temperature of the evaporator 1 can be set appropriately high at the time of cold heat output. In addition, due to the vapor-liquid equilibrium relationship between the refrigerant vapor and the absorption liquid, the concentration of the regenerated absorption liquid can be set low under a certain condition of the absorption operation temperature of the absorber. The maximum regeneration temperature in the case of utility can be set low, and the heat source fluid can be used at a lower temperature or lower quality, so that the heat energy utilization efficiency of the heat source can be improved.
Fourth, since the concentration of the regenerated absorbent solution can be set low, the possibility of occurrence of operational troubles due to the crystal phenomenon of the absorbent solution is reduced or eliminated.
No. 5, instead of the relatively large circulating water power at the time of cooling / heating output of the circulating cold / hot water, the required circulating secondary refrigerant power is extremely small, and the energy saving effect is remarkable.
No. 6, periodic cleaning of the heat exchanger tube 1aA of the heat exchanger of the evaporator 1 is not necessary.
