Description

本発明は、一重効用吸収冷温水機に関するものであり、詳しくは、ボイラ、エンジンの冷却水など排熱を駆動熱源として用いる再生器を備えた吸収冷温水機に関する。   The present invention relates to a single-effect absorption chiller / heater, and more particularly, to an absorption chiller / heater equipped with a regenerator that uses exhaust heat as a drive heat source, such as boiler and engine cooling water.

従来、エンジンの冷却水などを再生器の熱源とする吸収冷温水機が提案されている(例えば、特許文献1、2などを参照)。
このような吸収冷温水機は、ボイラやエンジンの冷却水などの冷却水を熱源として、再生器で希吸収液から冷媒を蒸発分離させて凝縮器へと送るとともに、前記冷媒が蒸発して濃度の濃くなった吸収液を吸収器へと送っていた。そして、凝縮器では、前記冷媒を冷却水により凝縮させ、冷媒液として蒸発器へと送り、蒸発器では、前記冷媒を負荷へと循環させるブラインが循環する伝熱管に散布して再蒸発させ、吸収器では、前記再蒸発した冷媒を吸収液に吸収させるとともに、前記冷却水により吸収液の熱を回収させて、前記負荷への冷熱供給運転を行うものとなっていた。また、前記冷却水は冷却塔へと循環され、大気へ放熱されている。
Conventionally, an absorption chiller / heater that uses engine coolant or the like as a heat source of the regenerator has been proposed (see, for example, Patent Documents 1 and 2).
Such an absorption chiller / heater uses cooling water such as boiler and engine cooling water as a heat source, evaporates and separates the refrigerant from the diluted absorbent in the regenerator and sends it to the condenser. The thickened absorption liquid was sent to the absorber. And in the condenser, the refrigerant is condensed with cooling water and sent to the evaporator as a refrigerant liquid, and in the evaporator, the refrigerant is sprayed on a heat transfer tube through which the brine circulating to the load circulates and re-evaporates. In the absorber, the re-evaporated refrigerant is absorbed by the absorption liquid, and the heat of the absorption liquid is recovered by the cooling water, and the cold supply operation to the load is performed. The cooling water is circulated to the cooling tower and radiated to the atmosphere.

また、これに対し、欧州などでは、この一重効用吸収冷温水機の再生器へ主熱源の熱源供給を行うとともに、蒸発器へ副熱源の熱源供給行い、上記冷熱供給運転時に利用していた冷却水をブラインとして凝縮器および吸収器から負荷へと循環させて、吸収ヒートポンプとしての運転を行わせ、上記負荷への温熱供給運転を行うものとなっていた。

On the other hand, in Europe, etc., the main heat source is supplied to the regenerator of this single effect absorption chiller / heater, and the auxiliary heat source is supplied to the evaporator. Water was circulated as a brine from the condenser and the absorber to the load, and the operation as an absorption heat pump was performed, and the heat supply operation to the load was performed.
Japanese Patent Laid-Open No. 58-127066 JP-A-8-233391

しかしながら、従来は、一重効用吸収冷温水機としての利用か、あるいは、吸収ヒートポンプとしての利用かのいずれか一方での利用であったため、一重効用吸収冷温水機を選択した場合には、冬場の温熱供給運転ができなくなり、吸収ヒートポンプを選択した場合には、夏場の冷熱供給運転ができないものとなっており、稼働率が上がらないものとなっていた。
このため、特に、欧州では、近年の地球温暖化により、夏季気温が上昇してきていることから、吸収ヒートポンプを一重効用吸収冷温水機として使用し、冷熱供給運転を行わせたいと言う要望が高まりつつあり、この点に対して改善が望まれている。
そこで、本発明では、冷熱供給運転および温熱供給運転が容易に切換えて行えるとともに、冷熱供給運転時においても、温熱供給運転時においても、運転可能な一重効用吸収冷温水機を提供することにある。
However, since it was conventionally used either as a single-effect absorption chiller / heater or as an absorption heat pump, when a single-effect absorption chiller / heater is selected, When the heat supply operation cannot be performed and the absorption heat pump is selected, the cold heat supply operation cannot be performed in the summer, and the operation rate does not increase.
For this reason, especially in Europe, the summer temperature has risen due to recent global warming, so there is a growing demand to use an absorption heat pump as a single-effect absorption chiller / heater and perform a cold supply operation. Improvement is desired for this point.
Accordingly, the present invention provides a single-effect absorption chiller / heater that can be easily switched between a cold supply operation and a hot supply operation, and that can be operated in both the cold supply operation and the hot supply operation. .

蒸発器の出口に第1温度検出器を、凝縮器の出口に第2温度検出器を夫々設けるとともに、負荷が第1ブライン管または第2ブライン管に択一的に接続切換される第1切換弁を設けるとともに、吸収器が負荷または冷却塔に択一的に接続切換される第2切換弁と、蒸発器が負荷または副熱源に択一的に接続切換される第3切換弁とを設け、第1切換弁を切換えて負荷が第1ブライン管に接続切換えされるときは、第2切換弁を切換えて吸収器を冷却塔へ接続するとともに、第3切換弁を切換えて蒸発器を負荷へと接続し、第1温度検出器で検出される温度により流量制御弁の開度を制御して負荷への冷熱供給運転を行い、第1切換弁を切換えて負荷が第2ブライン管に切換接続されるときは、第2切換弁を切換えて吸収器を負荷へ接続するとともに、第3切換弁を切換えて蒸発器を副熱源へと接続し、第2温度検出器で検出された温度により流量制御弁の開度を制御して負荷への温熱供給運転を行うことを特徴とするものである。

On the other hand, the cooling power is selected to be circulated and supplied from the evaporator 3 to the load (cooling) 24 via the first brine pipe (cold water pipe 16) (indicated by a thick black line in the figure).

すなわち、三方弁A、三方弁Bからなる第1切換弁を切り換えて負荷24が第1ブライン管(冷水配管16)に接続切換されるとともに、三方弁C、三方弁Dおよび三方弁Eからなる第3切換弁が切換えられて蒸発器3が負荷24へ接続されて第1ブライン管(冷水配管16)を介して冷熱が負荷24へ循環供給され(図中黒太線で示す)、一方、三方弁Fからなる第2切換弁が切換えられて吸収器4が冷却塔29へ接続され、吸収器4および凝縮器2へ冷却塔29から供給される冷却水を冷却水管15を介して循環させ(図中黒太線で示す)、第1温度検出器17で検出される温度により流量制御弁14の開度を制御して負荷24への冷熱供給運転を行うようになっている。   That is, the load 24 is connected and switched to the first brine pipe (cold water pipe 16) by switching the first switching valve including the three-way valve A and the three-way valve B, and the three-way valve C, the three-way valve D, and the three-way valve E.

The first temperature detector 17 detects a cold water outlet temperature provided in the middle of the cold water pipe 16 downstream of the evaporator heat exchanger 7. The first temperature detector 17 is used during cooling operation.
Reference numeral 18 denotes a second temperature detector that detects a hot water outlet temperature provided in the middle of the cooling water pipe 15 downstream of the condenser heat exchanger 6. The second temperature detector 18 is not used during the cooling operation.

流量制御弁14の開度によって決まる駆動熱源11から供給される駆動熱源温水が供給配管12を通って再生器1の加熱器5へ流れる。再生器1において濃度が薄い吸収液(稀吸収液という)が加熱され、稀吸収液から冷媒が分離して蒸発し、濃い吸収液(濃液という)が生じる。   Drive heat source hot water supplied from the drive heat source 11 determined by the opening degree of the flow control valve 14 flows to the heater 5 of the regenerator 1 through the supply pipe 12. In the regenerator 1, the absorbing solution having a low concentration (referred to as a rare absorbing solution) is heated, and the refrigerant is separated from the diluted absorbing solution and evaporated to produce a thick absorbing solution (referred to as a concentrated solution).

蒸発した冷媒は凝縮器2へ流れ、凝縮器熱交換器6を流れる冷却水と熱交換して凝縮液化し、冷媒配管21を経て蒸発器3へ流れる。
蒸発器3へ流れて溜った冷媒は、冷媒ポンプ22により冷媒配管23を経て蒸発器熱交換器7上に散布され、そして、冷媒液が蒸発器熱交換器7を流れる冷水と熱交換して蒸発し、気化熱によって冷水が冷却されて冷水配管(第1ブライン管)16に接続された負荷(冷房負荷)24へ冷温水ポンプ30により三方弁D、Aを経て供給されて冷房を行った後、三方弁C、Eを経て循環される。
The evaporated refrigerant flows to the condenser 2, exchanges heat with the cooling water flowing through the condenser heat exchanger 6 to be condensed and liquefied, and flows to the evaporator 3 through the refrigerant pipe 21.
The refrigerant that has flowed and accumulated in the evaporator 3 is sprayed onto the evaporator heat exchanger 7 via the refrigerant pipe 23 by the refrigerant pump 22, and the refrigerant liquid exchanges heat with cold water flowing through the evaporator heat exchanger 7. The chilled water is cooled by the heat of vaporization, and is supplied to the load (cooling load) 24 connected to the chilled water pipe (first brine pipe) 16 through the three-way valves D and A to the load (cooling load) 24 for cooling. Then, it is circulated through the three-way valves C and E.

そして、第1温度検出器17により検出した信号がスイッチ19を経て制御装置20に入力され、制御装置20から信号を出力して制御弁14の開度の制御が適正に行なわれる。   Then, the signal detected by the first temperature detector 17 is input to the control device 20 through the switch 19, and the signal is output from the control device 20 so that the opening degree of the control valve 14 is appropriately controlled.

また、蒸発器3で蒸発した冷媒は吸収器4へ流れる。一方、再生器1で生じた濃液は、濃液熱交換器25で稀吸収液ポンプ26により吸収器4から稀吸収液配管27を経て送られた稀吸収液と熱交換した後、濃液配管28を経て吸収器熱交換器8に散布される。吸収器4へ流れた冷媒は吸収器熱交換器8に散布された濃液に吸収され稀吸収液となる。   Further, the refrigerant evaporated in the evaporator 3 flows to the absorber 4. On the other hand, the concentrated liquid generated in the regenerator 1 is heat-exchanged with the diluted absorbent sent from the absorber 4 through the diluted absorbent pipe 27 by the diluted absorbent pump 26 in the concentrated liquid heat exchanger 25, and then concentrated liquid. It is sprayed to the absorber heat exchanger 8 through the pipe 28. The refrigerant that has flowed to the absorber 4 is absorbed by the concentrated liquid dispersed in the absorber heat exchanger 8 and becomes a rare absorbent.
