Description
図4において、濃溶液は、蒸発器Eで蒸発した冷媒蒸気を吸収器Aで吸収して希溶液となり、溶液ポンプSPにより流路1から溶液熱交換器SHの被加熱側を通り、流路2から再生器Gに導入される。再生器Gに導入された希溶液は、熱源12により加熱されて冷媒を蒸発して濃溶液となり、流路3から溶液熱交換器SHの加熱側を通り、流路4から吸収器Aに導入され、再び冷媒蒸気を吸収して希溶液となり循環される。
この場合、流す冷却水量は、吸収器と凝縮器のいずれかの必要冷却水量によって、一方的に決定される。
並列に冷却水を流す場合、吸収器と凝縮器とに導く流量を設計値に合わせるため、冷却水流路に流量調節弁を設け、この弁で流路抵抗を付けて調節することが考えられるが、水圧の変動等による流量調節弁の調節が複雑で操作上の問題がある。
吸収器(A)と凝縮器(C)に、熱量に比例した流量を流すと、冷却水の出入口温度差(温度上昇)は同じになる。
QA=GA×Cp×ΔTA
QC=GC×Cp×ΔTC
QA/QC=GA/GCのとき、ΔTA=ΔTC
冷却水の入口温度は同じなので、出口温度も同じになる。
吸収器側の流量を少な目にして、凝縮器側への流量を多くすることにより、凝縮温度を下げて、結果的に高温再生器の圧力と溶液温度を下げることができ、腐食の抑制に効果がある。ΔTA>ΔTCとすることにより、これが実現できる。
図1は、プレート式熱交換器を用いた本発明の吸収冷凍機の一例を示す単効用の吸収冷凍機の全体構成図である。
図1において、Aは吸収器、Gは再生器、Cは凝縮器、Eは蒸発器、SHは溶液熱交換器、SPは溶液ポンプ、FPは冷媒ポンプ、H1〜H4はプレート式熱交換器、1〜4は溶液流路、5,6は冷媒流路、7〜10は冷却水流路、11は冷水流路、12は熱源流路である。
冷却水は、流路7から導入され、流路8、9に分岐して、吸収器Aと凝縮器Cにそれぞれ導入され、流路10から排出される。
図2において、Aは吸収器、Gは低温再生器、Cは凝縮器、Eは蒸発器、GHは高温再生器、HSHは高温溶液熱交換器、SHは低温溶液熱交換器、SPは溶液ポンプ、FPは冷媒ポンプ、H 1 〜H 4 はプレート式熱交換器、1〜4,15〜18は溶液流路、5,6,13,14は冷媒流路、7〜10は冷却水流路、11は冷水流路、12は加熱熱源である。
冷却水は、流路7から導入され、流路8,9に分岐して、吸収器Aと凝縮器Cにそれぞれ導入され、流路10から排出される。
この場合、プレート枚数の配分比は、吸収器:凝縮器=12/(12+6):6/(12+6)=67:33となり、このようにプレート枚数に差をつけることで、それぞれに供給される冷却水の量を好適に分配することができる。
Claims (2)
- 少なくとも吸収器と凝縮器にプレート式熱交換器を用いた吸収冷凍機であって、冷却水を前記吸収器と凝縮器のプレート式熱交換器に並列に供給すると共に、供給する冷却水の吸収器と凝縮器の分配量が、主に、それぞれのプレート式熱交換器の流体抵抗で決まるように構成されていることを特徴とする吸収冷凍機。
- 前記吸収器と凝縮器に用いるプレート式熱交換器は、プレートの形状が同一で、その枚数が異なっていることを特徴とする請求項1記載の吸収冷凍機。
