にできる。In absorption chiller/hot water equipment that operates using engine exhaust heat as a heat source, in addition to producing cold/hot water, the role of the absorption chiller/heater is to cool the heat source.
Modes can be smoothly changed between cooling operation mode, heating operation mode, and cooling tower independent operation mode. In addition, in the present invention, even in the cooling operation mode or heating operation mode, if the heat source is excessive (when the heat source is hot water, it is detected by the hot water temperature, and when the heat source is steam, it is detected by the steam pressure), automatic control is performed. The heat source can also be easily released into the cooling water by controlling the valve Vw.
冷却塔の運転、冷却器への冷却水流量制御動作は、冷温
水機の運転制御と深く関わり、各モードの制御は、冷温
水機制御盤で行うのが、好ましい。The operation of the cooling tower and the control of the flow rate of cooling water to the cooler are closely related to the operation control of the water chiller/heater, and each mode is preferably controlled by the water chiller/heater control panel.
各モードの制御は次のようになる。Control of each mode is as follows.
冷房運転モード：自動制御弁Ｖｒを開として、冷却水を
冷温水機に通水し、
吸収冷温水機は冷房サイクル

熱源過剰の場合、自動制御弁 Ｖｗを制御して、熱源を冷却 水に放出する。Automatic control valve in case of excess heat source Control Vw to cool the heat source Release into water.
暖房運転モード：自動制御弁Ｖｒを閉として、冷温水機
には冷却水を通水せ
ず、吸収冷温水機は暖房サイ
クルをする。Heating operation mode: Automatic control valve Vr is closed, cooling water is not passed through the chiller/heater, and the absorption chiller/heater performs a heating cycle.
熱源過剰の場合、自動制御弁 Ｖｗを制御して、熱源を冷却 水に放出する。Automatic control valve in case of excess heat source Control Vw to cool the heat source Release into water.
また吸収冷温水機内の冷却水 の有無は、冷却永存で、起動 すると起動の時間がかかる。Also, the cooling water in the absorption chiller/heater Can be permanently cooled and activated Then it takes time to start up.
しかし、冷房に切り替える際 は、すぐに冷房に入っていけ る。これは無では、吸収器、 凝縮器の満水に時間がかかる ためである。自動弁Ｖｒと吸 酸型の間を始点とし、冷却塔 を終点として、自動弁を有す る冷却水ブロー配管を設けて もよい。この自動弁の制御は、 冷暖房の切替が頻繁に予想さ れる場合は、閉として、フロ ーせず、暖房が続く場合は、 開として、ブローしてもよい。However, when switching to cooling Please go into the air conditioner immediately. Ru. This is nothing but an absorber, It takes a long time to fill the condenser with water. It's for a reason. Automatic valve Vr and suction The starting point is between the acid forms, and the cooling tower with an automatic valve as the end point Install cooling water blow piping. Good too. The control of this automatic valve is Frequent switching of heating and cooling is expected. If the If the heating continues without heating, You may also blow it open.
予想としては、季節を根拠に してもよい。たとえば、冬期 の暖房時は開とし、中間期に は閉とする。Forecasts are based on the season. You may. For example, in winter Open during heating period, and open during heating period. shall be closed.

パスする冷却水とを混合し、許容温度以下としている。If the heat source is excessive, the automatic control valve Vw is controlled to release the heat source into the cooling water, but if the cooling water does not flow for a long period of time, the cooling water in the heat source cooler will reach the same temperature as the heat source. It increases to If it flows out, it will damage the cooling tower (the allowable temperature of the cooling tower is about 50 to 60°C; the filling material is made of plastic). As a countermeasure for this, a cooling water bypass line is provided for the heat source cooler, and the cooling water passing through the cooler is mixed with the cooling water bypassing the cooler to keep the temperature below the allowable temperature.

。To explain the cooling cycle in the cooling operation mode, first, the dilute solution that has absorbed the refrigerant passes from absorber A through pipe 1,
The dilute solution is sent to the heated side of the heat exchanger by the pump 11 and heated by the heat exchange, and is introduced into the generator G through the pipe 2. In the generator G, it is heated by a heat source such as engine jacket hot water from the pipe 14, and the absorbed refrigerant vapor is evaporated and concentrated. The concentrated solution passes through the heating side of the heat exchanger H from the tube 3, is introduced into the absorber A from the tube 4, absorbs the refrigerant again, becomes a dilute solution, and is circulated from the tube 1.

６の指令により自動制御弁Ｖｗを制御して熱源を冷却水
に放出する。In the evaporator E, the refrigerant removes heat from the cold water, exhibits a freezing effect, and evaporates. The evaporated refrigerant vapor is absorbed into a solution in absorber A. During absorption, the absorbed heat flows through the absorber through the pipe 24.
It is cooled by cooling water from In such operation, if the heat source supplied to the generator is excessive, temperature sensor 1
The automatic control valve Vw is controlled by the command No. 6 to release the heat source to the cooling water.
また、暖房運転モードでは、自動制御弁Ｖｒを閉として
、冷温水機には冷却水を通水せず暖房サイクルで運転す
る。In addition, in the heating operation mode, the automatic control valve Vr is closed, and the cold/hot water machine is operated in the heating cycle without passing cooling water.
次に、暖房運転モードにおける暖房サイクルを説すする
。Next, the heating cycle in the heating operation mode will be explained.
暖房運転では、吸収器Ａからの溶液を管１から溶液熱交
換器Ｈの被加熱側に導入し、加熱側の濃溶液と熱交換し
て温度を高め、溶液熱交換器Ｈを出た後、管２から発生
器Ｇに導入される。In heating operation, the solution from absorber A is introduced through tube 1 to the heated side of solution heat exchanger H, heat exchanges with the concentrated solution on the heating side to increase the temperature, and after leaving solution heat exchanger H , is introduced into the generator G through tube 2.
ここで溶液は、外部熱源１４により加熱され濃縮される
。濃縮された濃溶液は、発生器Ｇから管３により溶液熱
交換器Ｈの加熱側に入り、被加熱側の希溶液を加熱して
管４から吸収器Ａに入る。Here, the solution is heated and concentrated by an external heat source 14. The concentrated solution enters the heating side of the solution heat exchanger H from the generator G through a pipe 3, heats the dilute solution on the side to be heated, and enters the absorber A through a pipe 4.
発生器Ｇで溶液の濃縮が行われる際発生する冷媒蒸気は

与えて凝縮する。凝縮した冷媒液は、吸収器Ａに流入す
る。ここでは、冷媒液は、管６、冷媒ポンプ１２、管８
及び冷媒液弁１０を通して流れる。The refrigerant vapor generated when the solution is concentrated in the generator G is guided from the pipe 7 to the evaporator E by opening the refrigerant vapor valve 9 of the refrigerant vapor pipe 7 connecting the high pressure side and the low pressure side. ,
The hot water (air conditioning fluid) from the pipe 18 passing through the evaporator E is given heat and condensed. The condensed refrigerant liquid flows into absorber A. Here, the refrigerant liquid flows through the pipe 6, the refrigerant pump 12, and the pipe 8.
and flows through the refrigerant liquid valve 10.
冷媒ポンプ１２は停止していても差支えない。There is no problem even if the refrigerant pump 12 is stopped.
また、冷媒蒸気弁９は、外部流体温度検出器１９による
流体温度の検出により、開閉でき温度調節ができる。Further, the refrigerant vapor valve 9 can be opened and closed to adjust the temperature by detecting the fluid temperature by the external fluid temperature detector 19.
吸収器に入った溶液は、吸収塔が低圧のだと冷媒の蒸気

らの冷媒液と混合されて希溶液となって、管１から溶液
熱交換器Ｈに入り、循環して暖房サイクルを形成する。When the absorption tower has a low pressure, the solution entering the absorber has a high vapor pressure of the refrigerant, and the temperature of the solution decreases by releasing the refrigerant vapor. The released refrigerant vapor is condensed in the evaporator E together with the refrigerant vapor on the high pressure side. The solution leaves the absorber A intact, mixes with the refrigerant liquid from the evaporator E to form a dilute solution, enters the solution heat exchanger H through the tube 1, and is circulated to form the heating cycle.
このような暖房サイクルの運転においても、発生器に供
給される熱源が過剰の場合は、温度検出器１６の指令に

出する。Even in such heating cycle operation, if the heat source supplied to the generator is excessive, the automatic control valve Vw is controlled by a command from the temperature detector 16 to release the excess heat source to the cooling water.
また、熱源としてエンジンの排出熱などを用いる場合、
冷温水を製造する以外に熱源を冷却する役目もあるため
、冷却塔単独運転を作り、冷却塔単独運転モードでは、
冷温水機のサイクル運転は停止して、自動制御弁Ｖｗを
制御して、熱源冷却器１５に冷却水を流し熱源を冷却水
に放出させる。In addition, when using engine exhaust heat as a heat source,
In addition to producing hot and cold water, the cooling tower also has the role of cooling the heat source, so we created cooling tower independent operation, and in the cooling tower independent operation mode,
The cycle operation of the cold/hot water machine is stopped, and the automatic control valve Vw is controlled to flow cooling water into the heat source cooler 15 and release the heat source into the cooling water.
熱源冷却器１５からの熱源の放出がない場合は、熱源冷
却器１５内の冷却水は熱源温度と同程度まで高まるため

通路２２より冷却水を流し、高温の冷却水を低下させて
から冷却塔に流すように操作する。If no heat source is released from the heat source cooler 15, the cooling water in the heat source cooler 15 will rise to the same level as the heat source temperature. The system is operated so that the water is allowed to flow and the high temperature cooling water is lowered before flowing into the cooling tower.
