It also relates to a dual effect absorption refrigerator with valves.

れる。 The concentrated solution heated in the high-temperature regenerator 3 is guided to the gas-liquid separator 10 along with the generated refrigerant vapor through a liquid lift pipe 11, and is separated into refrigerant vapor and solution. The separated solution flows into the liquid level detection chamber due to the pressure difference between the pressure in the high temperature regenerator 3, that is, the pressure H 10 m solution column in the gas-liquid separator 10 and the pressure H 4 m liquid column in the low temperature regenerator 4. 12 and is led to a high temperature heat exchanger 6 through a solution return pipe 15, and after heating the dilute solution, a squeezing mechanism 17
and is led to the low temperature regenerator 4 via a solution return pipe 16.

減少による溶液ポンプ８のキヤビテーシヨン現象
を防止している。 When the solution level in the liquid level detection chamber 12 is low, the liquid level detector 13 controls the solution flow rate control valve 14 in the opening direction to prevent the high temperature regenerator 3 from running dry; In this case, the liquid level detector 13 controls the solution flow rate control valve 14 in the closing direction, and the solution liquid level in the liquid level detection chamber 12 and the upper gas-liquid separator 10 rises excessively, causing the refrigerant vapor flow of the solution. This prevents a carry-over phenomenon to occur, and also prevents cavitation of the solution pump 8 due to an excessive decrease in the amount of solution in the absorber 1.

However, since the liquid pumping action to the gas-liquid separator 10 by the liquid pumping pipe 11 is due to the bubble pumping action of the refrigerant vapor generated in the high-temperature regenerator 3, it is intermittent, making it difficult to obtain a uniform flow rate. The balance with the solution return capacity from the solution return piping 15 tends to become unstable, and as soon as the instability of the flow rate is corrected, the surplus will remain as a pool, and the shortage will appear as a decrease in liquid, so the liquid level detection chamber 12 There is a problem in that the liquid level of the solution inside tends to become unstable, and as a result, the control of the solution flow rate control valve 14 based on the signal from the liquid level detector 13 tends to become unstable. In addition, if an excess of solution is introduced into the gas-liquid separator 10 through the liquid pumping pipe 11, there is a problem that the solution level in the high-temperature regenerator 3 decreases and there is a risk of dry firing.
またこの種の冷凍機では通常溶液流量制御弁１

備している。 Also, in this type of refrigerator, the solution flow control valve 1 is usually
4, a self-powered float valve as shown in FIG. 4 is provided in the liquid level detection chamber 12 to prevent leakage to the outside of the machine.

効率の低下を齎す問題点も併せ有するもであつ
た。 However, since the valve part of the self-powered float valve as the solution flow rate control valve 14 is located on the discharge side of the solution pump 8, when the valve part is on the closing side, the pressure at the shaft seal part of the self-powered float valve increases, causing As shown in FIG. 4, the amount of dilute solution leaking into the solution return pipe 15 through the shaft seal portion 18 is a non-negligible amount, resulting in a reduction in efficiency.

のであつた。 In addition, especially when the refrigeration load is high and the cooling water temperature is low, the pressure of the high temperature regenerator 3, that is, the gas-liquid separator 1
Pressure in 0 H 10 m solution column and pressure in low temperature regenerator 4
The pressure difference with the H 4 m solution column becomes small, and the liquid return capacity tends to be insufficient. In this case, liquid level detection chamber 1
As the solution level in the absorber 2 rises and the liquid level detector 13 throttles the solution flow rate control valve 14, the difference between the solution concentration in the high-temperature regenerator 3 and the solution concentration in the absorber 1 becomes too large, causing crystallization. It also had the problem of causing smearing properties.

It is an object of the present invention to provide a dual-effect absorption refrigerator that is not guided to a regenerator 4 and can prevent a decrease in efficiency.

The present invention, as a means to solve the above problems,
A dual-effect absorption refrigeration cycle is created using an absorber, evaporator, condenser, low-temperature regenerator, high-temperature regenerator, high-temperature solution heat exchanger, low-temperature solution heat exchanger, solution pump, and the solution path and refrigerant path that connect these. a solution flow rate control valve configured to have a gas-liquid separator connected above the high-temperature regenerator by a pumping pipe, and to control the amount of solution flowing into the high-temperature regenerator in the solution path on the discharge side of the solution pump; In a dual-effect absorption refrigerator having
A liquid level detection chamber is provided below the gas-liquid separator, and the liquid level detection chamber receives the solution flowing down from the gas-liquid separator and places a detection liquid at a position lower than the liquid level of the gas-liquid separator. The lower part of the gas-liquid separator is connected to the high temperature solution heat exchanger via a solution path, and the lower part of the gas-liquid separator is connected to the high temperature solution heat exchanger through a solution path, and A lower part of the regenerator is connected to a lower part of the high temperature regenerator via a solution path, and the solution flow rate control valve is controlled by a detection signal from the liquid level detector. It is something to do.
次に本発明の実施例を第１図にもとづいて説明
する。
Next, an embodiment of the present invention will be described based on FIG.
１９は、液面検出室１２の下部と高温再生器３
とを接続する溶液配管である。溶液戻り配管１５
は気液分離器１０の下部と高温熱交換器６とを接
続している。そそ他第１図において第３図と同一
符号の部分は同様な構成作用を有する。 19 is the lower part of the liquid level detection chamber 12 and the high temperature regenerator 3
This is the solution piping that connects the Solution return piping 15
connects the lower part of the gas-liquid separator 10 and the high-temperature heat exchanger 6. In addition, parts in FIG. 1 having the same reference numerals as those in FIG. 3 have similar structural functions.
高温再生器３内で加熱された濃縮された溶液は

器１０へ導かれ、冷媒蒸気と溶液に分離される。
分離された溶液高温再生器３内の圧力、即ち気液

高温熱交換器６に導かれ、希溶液を加熱後絞り機
構１７を通り溶液戻り配管１６にて低温再生器４
に導かれる。 The concentrated solution heated in the high-temperature regenerator 3 is guided along with the generated refrigerant vapor to the gas-liquid separator 10 through a liquid lift pipe 11, and is separated into refrigerant vapor and solution.
The pressure in the separated solution high temperature regenerator 3, that is, the pressure in the gas-liquid separator 10 H 10 m solution column and the low temperature regenerator 4
Due to the pressure difference △H 2 between the internal pressure H 4 m and the solution column, the dilute solution is directly guided from the bottom of the gas-liquid separator 10 through the solution return pipe 15 to the high-temperature heat exchanger 6, and after being heated, passes through the throttle mechanism 17. Low temperature regenerator 4 at solution return pipe 16
guided by.
一方揚液管１１にて余剰に気液分離器１０へ導
かれた溶液は、溶液戻り配管１５より戻りきらな
い為、気液分離器１０の下方に配備した液面検出
室１２に流入し、液面検出室１２下部より溶液配
管１９により高温再生器３に速やかに戻される。 On the other hand, the excess solution guided to the gas-liquid separator 10 through the liquid lift pipe 11 cannot be returned through the solution return pipe 15, so it flows into the liquid level detection chamber 12 located below the gas-liquid separator 10. The solution is quickly returned to the high temperature regenerator 3 from the lower part of the liquid level detection chamber 12 via the solution pipe 19.
この為、高温再生器３内の溶液液面が安定に保
たれ空焚きの危険性がなくなるばかりか、従来の
ものの如く、余剰分が液面検出室に溜ることなく
液面検出室１２内の溶液液面も安定に保たれる
為、液面検出器１３の信号による溶液流量制御弁
１４の制御も安定したものとなる。 For this reason, not only is the solution level in the high temperature regenerator 3 kept stable, eliminating the danger of dry firing, but also the excess content in the liquid level detection chamber 12 is maintained without accumulating in the liquid level detection chamber unlike in conventional systems. Since the solution level is also kept stable, the control of the solution flow rate control valve 14 based on the signal from the liquid level detector 13 also becomes stable.

気液分離器１０下部にある為、従来の溶液戻り口
が液面検出室１２下部にある場合に比較して戻り
抵抗が△hm溶液柱（＝△H1m溶液柱−△H2m溶
液柱）分だけ減少する為溶液戻り能力が改善され
る。 In addition, since the solution return port that connects the solution return pipe 15 is located at the bottom of the gas-liquid separator 10, the return resistance is reduced by △hm solution column (= The solution return ability is improved because it decreases by △H 1 m solution column - △H 2 m solution column).
また、こように△hmの溶液柱分の圧力だけ溶

防ぎ、結晶を防止することができる。 In addition, by increasing the solution return capacity (high temperature regenerator 3 → low temperature regenerator 4) by the pressure of the solution column of Δhm in this way, the liquid level in the liquid level detector 12 rises (return capacity is insufficient). ) to prevent the solution flow rate control valve 14 from being unnecessarily throttled, thereby preventing the solution concentration in the high temperature regenerator 3 from becoming excessive and preventing crystallization.

ない。 In addition, a solution return pipe 15 to the high temperature heat exchanger 6 is directly connected to the lower part of the gas-liquid separator 10, and the liquid level detection chamber 1
Since the lower part of 2 is connected to the lower part of the high temperature regenerator 3 by the solution piping 19, a self-powered float valve shown in FIG. Even if it is installed in the detection chamber 12, the dilute solution leaking from the shaft seal part 18 of the self-powered float valve is not led to the high temperature heat exchanger 6 but to the high temperature regenerator 3, so there is no loss. No loss of efficiency.
