Field of the Invention The present invention improves the performance by improving the structure and arrangement of equipment constituting the low temperature drum of an absorption chiller / cooling / heating machine. The present invention relates to an absorption chiller / cooling / heating machine capable of simplifying the structure. 2. Description of the Related Art Conventionally, absorption refrigerators and cold / hot water machines using, for example, lithium bromide as an absorbent and, for example, water as a refrigerant are known. Such an absorption refrigerator / cooling / heating machine, for example, as an absorption cooling / heating machine,
As an example, a configuration as shown in FIG. 5 is known. In the absorption chiller / heater shown in FIG. 5, the low temperature regenerator 10, the condenser 12, the absorber 14, the evaporator 16, the high temperature regenerator 18,
The low-temperature heat exchanger 20, the high-temperature heat exchanger 22, and pipes that connect these devices are provided, and the diluted liquid in the absorber 14 is
It is sent to the low temperature regenerator 10 through the pipe line 26, the low temperature heat exchanger 20, and the pipe line 28 by the low temperature pump 24. The rare liquid of the low temperature regenerator 10 is heated by the high-temperature refrigerant vapor that has flowed from the gas-liquid separator 30 of the high temperature regenerator 18 via the pipe line 32 and is concentrated to an intermediate concentration. This intermediate concentration liquid is divided in two. One of the bisected liquids is supplied by the high-temperature pump 34 to the pipelines 36, 38,
It is sent to the high temperature regenerator 18 through the high temperature heat exchanger 22 and the pipe line 40. The intermediate concentration liquid in the high-temperature regenerator 18 is removed from the combustion device 42.
Then, the heat recovery unit 44 rises and enters the gas-liquid separator 30 to be separated into refrigerant vapor and concentrated liquid. The concentrated liquid in the gas-liquid separator 30 is supplied from the pipe 46, the high temperature heat exchanger 22, and the pipe 4.
8, mixed with the intermediate concentration liquid from the pipe 50 (the other of the half-divided intermediate concentration liquid), mixed into a concentrated liquid, introduced into the low-temperature heat exchanger 20, and then passed through the pipe 52. Spraying device 5
4 is spread on the heat transfer tube of the absorber 14. On the other hand, the refrigerant vapor separated by the gas-liquid separator 30 enters the low-temperature regenerator 10 through the pipe line 32, where it condenses and liquefies by heating the liquid and enters the condenser 12. The refrigerant vapor generated when the dilute liquid is concentrated to an intermediate concentration in the low-temperature regenerator 10 enters the condenser 12 and condenses, and then enters the evaporator 16, and the condensed refrigerant water is piped by the refrigerant pump 56. It is sprayed on the heat transfer tube of the evaporator 16 by the spraying device 60 via the path 58. In addition, 62 is a combustion chamber and 64 is an exhaust pipe. [0004] In addition, a low temperature drum of a conventional absorption refrigerator / cooling / heating machine has a configuration as shown in FIG. 6 as an example. That is, the absorber 14 is disposed at the bottom of the main body 66 of the cryogenic cylinder, the evaporator 16 is disposed above the absorber 14, and the low-temperature regenerator 10 and the condenser 12 are disposed above the evaporator 16. Yes. The heat transfer tube 68 of the absorber 14 has a spraying device 5.
The absorbing liquid is sprayed from 4. Further, the non-condensable gas collected in the absorber 14 is exhausted through the extraction pipe 70.
Reference numeral 72 denotes an absorbing liquid reservoir, 74 denotes a low temperature regenerator liquid outlet box, 76 denotes a baffle plate, and 78 denotes a refrigerant reservoir. Further, the evaporator 16 is provided with a refrigerant flash pipe 80, and the refrigerant vapor from the refrigerant flash pipe 80 is in the upper heat transfer pipe 82.
Also, the refrigerant liquid is sent to the lower refrigerant reservoir 84.
This refrigerant liquid is spread by the spraying device 60 to the heat transfer tube 8 of the evaporator 16.
2, the evaporated refrigerant vapor is evaporated from the upper part of the evaporator 16 and the eliminator 86 on the side of the evaporator 16. As shown in FIG. 7, an extraction pipe 70 is installed between the heat transfer pipes 68 of the absorber 14 in the low temperature drum of the conventional absorption refrigerator / cooling / heating machine. Thus, the non-condensable gas is extracted from the extraction port 88 provided in the extraction pipe 70. Further, the refrigerant vapor flows into the absorber 14 only from the upper side of the heat transfer tube 68. Note that the arrows in FIG. 7 indicate the flow of the refrigerant vapor. However, in the configuration in which the extraction pipes are installed at the important points in the tube group, the non-condensable gas staying position does not necessarily coincide with the extraction port position of the extraction pipe. May lead to performance degradation. Further, in the configuration in which the refrigerant vapor flows only from the upper part of the tube group, the refrigerant vapor flow velocity at the inlet of the tube group becomes high, the pressure loss of the refrigerant vapor is large, and the absorber performance is reduced. [0006] Further, as described above, the eliminator is disposed at the refrigerant vapor outlet portion at the side of the evaporator tube group in the low temperature drum of the conventional absorption refrigerator / cooling / heating device. This is because the shape of the evaporator is vertically long, and if the refrigerant vapor evaporated by the evaporator flows out only from the upper part of the evaporator, the flow velocity of the refrigerant vapor becomes excessive, causing the refrigerant liquid to carry over or the refrigerant vapor pressure. This is because the loss becomes excessive, so that the refrigerant vapor flows out from the side of the tube group to prevent carryover of the refrigerant liquid. However, in the configuration in which the eliminator is installed on the side of the tube group of the evaporator, the structure of the evaporator is complicated.

Further, the low temperature regenerator liquid outlet box 116 is disposed on the condenser 112 side, and the low temperature regenerator 114 and the liquid outlet box 116 are connected by a connecting pipe 118. 120 is a baffle plate and 122 is a refrigerant reservoir. The absorber 108 is provided with a surrounding member 124 whose upper end is closed so as to surround a part of the tube group, and a bleed box 126 for non-condensable gas is formed.

8 is provided with a refrigerant vapor passage 132 on the side of the tube group, and a lower portion of the side surface of the refrigerant vapor passage 132 is closed by a baffle 134. 136 is an absorbent spraying device, 13
8 is an absorption liquid reservoir. Further, in the evaporator 110, the heat transfer tubes 140 are arranged so that the shape of the evaporator is horizontally long, and the tube pitch of the upper heat transfer tubes 140 is increased. By enlarging the refrigerant vapor passage at the top of the tube group, there is no need to install an eliminator on the side of the evaporator. The evaporator 1
10 is provided with a refrigerant flash pipe 142 (the structure will be described later). The refrigerant vapor from the refrigerant flash pipe 142 is sent to the upper heat transfer pipe 140, and the refrigerant liquid is sent to the lower refrigerant reservoir 144.

The lower part of the side surface is closed with a baffle 134. In addition, the arrow of FIG. 2 has shown the flow of the refrigerant | coolant vapor | steam and gas. In this way, by enclosing a part of the tube group as an extraction box, and collecting and extracting the gas in the extraction box, the non-condensable gas can be reliably exhausted, so the performance of the absorber is improved. In addition, a refrigerant vapor passage is provided on the side of the tube group, and the lower portion of the passage is closed with a baffle, so that not only gas is easily collected in the extraction box, but also refrigerant vapor flows from the upper and side of the tube group. Thus, the refrigerant vapor flow velocity at the inlet of the tube group is lowered, the pressure loss of the refrigerant vapor is reduced, and the performance of the absorber is improved. The second embodiment of the present invention is an evaporator structure in which the eliminator can be omitted. As shown in FIG. 1 described above, the heat transfer tubes 140 are arranged with the shape of the evaporator 110 being horizontally long, and the vertical and horizontal tube pitches of the upper heat transfer tubes 140 are increased so that the refrigerant vapor passage at the upper portion of the tube group is formed. The refrigerant vapor is made to flow out only from the upper part of the evaporator 110. In this way, the refrigerant vapor passage at the top of the tube group is expanded to suppress the flow velocity of the refrigerant vapor and reduce pressure loss, thereby eliminating the need for the refrigerant vapor to flow out from the side of the tube group and preventing carryover of the refrigerant liquid. Therefore, the eliminator can be omitted, and the structure of the evaporator can be simplified. Moreover, since the evaporator shape is horizontally long, as can be seen from FIG. 3 described later, the height of the low-temperature cylinder is lowered, and the installation height of the apparatus can be lowered. The third embodiment of the present invention is an arrangement of an evaporator, an absorber, a condenser, and a low temperature regenerator constituting a low temperature cylinder. As shown in FIG. 1 described above, the evaporator 110 is provided above the absorber 108, and the low temperature regenerator 1 is disposed above the evaporator 110.

In this case, as shown in FIG. 1, the low temperature regenerator liquid outlet box 116 is disposed on the side of the condenser 112 opposite to the high temperature regenerator, and the low temperature regenerator 114 and the liquid outlet box are disposed inside the low temperature cylinder. A connecting pipe 118 is provided for connecting to 116. As described above, when the low temperature regenerator is placed on the high temperature regenerator side, if the low temperature regenerator liquid outlet box is provided on the side of the low temperature regenerator, it is connected to the liquid outlet box between the low temperature cylinder and the high temperature regenerator. Since a space for piping is required, the machine width dimension is increased. Therefore, in order to solve this problem, a low temperature regenerator liquid outlet box is disposed on the side of the condenser, and a connecting pipe from the low temperature regenerator to the liquid outlet box is installed inside the low temperature cylinder. FIG. 4 is an enlarged view showing the details of the refrigerant flash tube of the evaporator shown in FIG. 1, and the configuration of the evaporator refrigerant flash tube in the low temperature drum of the absorption chiller / heater according to the fourth embodiment of the present invention. Is shown. As shown in FIG. 4, the refrigerant flash pipe 142 of the evaporator is composed of a flash pipe 156 and a lower tray 158, a hole 160 for spraying refrigerant is provided on the lower tray 158 side of the flash pipe 156, and the lower tray 158 has a refrigerant. Hole 1 for introducing liquid into the refrigerant reservoir
62 is provided. In this case, the refrigerant liquid from the condenser is ejected from the hole 160 of the flash tube 156 to the lower tray 158, the refrigerant vapor flows to the upper tube group, and the refrigerant liquid flows from the hole 162 of the lower tray 158 to the lower refrigerant pool. In addition,
The arrows in FIG. 4 indicate the flow of the refrigerant. Thus, the evaporator refrigerant flash tube can be constituted by the flash tube and the lower tray, and the structure becomes simple. In addition,
It is possible to configure the absorption refrigerator / cooling / heating machine by appropriately combining the configurations of the first to fourth embodiments described above. Since the present invention is constructed as described above, the following effects can be obtained. (1) surrounds the portion of the tube bundle of the absorber and extraction box, and
Furthermore, by providing a bleed port in the bleed box and collecting and evacuating the gas in the bleed box, the non-condensable gas can be reliably exhausted, so that the performance of the absorber is improved. In addition, when the refrigerant vapor passage is also provided on the side of the tube group and the lower portion of this passage is closed with a baffle, not only the gas is likely to collect in the extraction box, but also the refrigerant vapor flows from the upper and side portions of the tube group. Thus, the refrigerant vapor flow velocity at the inlet of the tube group is lowered, the pressure loss of the refrigerant vapor is reduced, and the performance of the absorber is improved. (2) By arranging the tube group with the shape of the evaporator horizontally long, and increasing the tube pitch at the upper part of the tube group to widen the refrigerant vapor passage at the upper part of the tube group, the refrigerant vapor can be drawn only from the upper part of the evaporator. It can be set as the structure made to flow out, and it becomes unnecessary to install an eliminator in the pipe group side part. Thereby, the structure of an evaporator is simplified. (3) The low temperature regenerator is placed on the high temperature regenerator side in the low temperature body of the absorption chiller / cooling / hot water machine, so that the cooling water communication pipe from the absorber to the condenser and the low temperature from the high temperature regenerator The refrigerant vapor piping to the refrigerant vapor header of the regenerator is shortest and simple. In this case, to place the low-temperature regenerator liquid outlet box to the condenser side, since the established connection pipe from the low-temperature regenerator to the liquid outlet box inside cold cylinder, between the cold cylinder and the high-temperature regenerator, liquid It is not necessary to provide a space for piping connected to the outlet box, and the machine width dimension is not increased. (4) Evaporating refrigerant on the bottom of the evaporator flash tube
It can be constituted by a flash tube provided with a hole to be formed and a lower tray, and the structure becomes simple.
