システムの冬期、夏期のフローシートである。As shown in the figure, hot water and cold water flow through hot water piping 8 and cold water piping 9 both in winter and summer, and are supplied to heating load 5 and cooling load 6, respectively. And only in winter, the heat source water is recovered by heat recovery piping 1.
0, and the heat is recovered from the heat recovery device 7. Reference numerals 11 and 12 are flow sheets for winter and summer, respectively, in the second basic system proposed in Japanese Patent Application No. 146889/1999. The cold water pipe 9 is the same as the first basic system, but the return pipe of the hot water pipe 8 is an intermediate hot water pipe 15 that is shared with the return pipe of the heat recovery pipe 10. Further, 13.13' is a flow sheet for the winter and summer seasons of a conventional four-pipe system that does not perform heat recovery. 14.1
4' is a flow sheet for the winter and summer seasons of a conventional two-pipe system that supplies hot water in the winter and cold water in the summer.
しかしながら、第４図の第１の基本システムの場合は、
主配管が６本であり、システムが複雑且つ高価なものと
なる。また、第２の基本システムの場合でも、主配管が
５本となり、システムが複雑且つ高価なものとなる。However, in the case of the first basic system in Fig. 4,
There are six main pipes, making the system complex and expensive. Furthermore, even in the case of the second basic system, there are five main pipes, making the system complex and expensive.
また、４管式の従来システムの場合でも、負荷から熱回
収ができず、２管式従来システムでは冬にも冷房が必要
な場合や、給湯負荷がある場合に適用できないという欠
点があった。Furthermore, even in the case of the four-pipe conventional system, heat cannot be recovered from the load, and the two-pipe conventional system has the disadvantage that it cannot be applied when cooling is required even in winter or when there is a hot water supply load.

This is a case where the load is heavy on heating and hot water supply, with some cooling load in addition to that. Hot water produced by the heat pump 30 in the heat supply center 4 is supplied by the hot water pump 31 to the district heating and cooling/hot water supply load system 21 via the hot water supply piping 8 and branch pipes 8a, 8b, 8c, and 8d, and is used for heating, heating, etc. Used for hot water supply load. The hot water then returns to the heat supply center 4 through the hot water return pipe 22. On the other hand, the cold water produced by the refrigerator 32 in the heat supply center 4 is fully supplied to the district heating and cooling/hot water supply load system 21 via the cold water supply pipe 9 and branch pipes 9a and 9b by the cold water pump 33, and the cooling load used for. The cold water is then returned to the heat supply center 4 through the cold water return pipe. If there is some cooling load as in the case of FIG. 1, the returned water passes through the flow path switching device 24 and then via the piping 34. Therefore, in this mode of operation, valve 35 remains closed. In addition, in the case of this operation mode, there is a shortage of heat, so it is necessary to recover it with the heat recovery device 18 provided in the external heat recovery system 3 or the district heating/cooling/hot water supply load system 21 shown in the figure. External heat recovery system 3 is used for condenser cooling water for waste incineration power generation equipment, refrigerator cooling water for large refrigerators, heat engine oil cooler cooling water, engine cooling water, transformer cooling water, and condensation for various industrial processes. It is composed of a heat recovery device 3 and piping 16, 17 for recovering heat from relatively high-temperature waste heat such as cooling and low-temperature hot springs, and low-temperature heat sources such as seawater and river water. Heat recovery device 1B
is a heat recovery device that recovers waste heat from the load of the district heating and cooling/hot water supply load system 21, that is, the hot water supply load, which was previously discarded via heat recovery piping 19,20. No. 2150 is a diagram showing the configuration of an air conditioning/hot water supply system using a heat pump showing another embodiment of the present invention;
) is a diagram showing the overall configuration of the heating, cooling, and hot water supply system;
a) is a diagram showing details of the heat supply center; The configuration is the same as in Figure 1, but the season is winter, and the load is mostly heating + hot water supply, with a slight cooling load. Hot water supply and return are the same as in FIG.
一方、冷水の供給は同じであるが戻りは戻り管２３では
なく温水戻り配管２２となる。このためバルブ３５は開
となる。On the other hand, although the cold water supply is the same, the return is through the hot water return pipe 22 instead of the return pipe 23. Therefore, the valve 35 is opened.
その理由は、この運転モードの場合は特に熱が第１図の
場合よりも足りなくなるので、図中の外部熱回収システ
ム３の他、熱回収装置１８からの熱回収が不可欠となる
。このため、第１図では冷水の戻り配管となっていた戻
り管２３を熱回収用の流体が熱供給センター４から地域
冷暖房・給湯負荷システム２１に供給され熱回収する。The reason for this is that in this mode of operation, there is less heat than in the case shown in FIG. 1, so it is essential to recover heat from the heat recovery device 18 in addition to the external heat recovery system 3 shown in the figure. For this reason, a fluid for heat recovery is supplied from the heat supply center 4 to the district heating and cooling/hot water supply load system 21 through the return pipe 23, which is a cold water return pipe in FIG. 1, to recover heat.
このため、流路切替装置２４により配管２６と戻り管２
３が連通きれ、熱源ポンプ２５が駆動されて、第１図の
場合と逆の流れが配管２３内に生じる。この結果、熱回
収装置１Ｂから十分な熱を回収することができる。For this reason, the flow path switching device 24 connects the pipe 26 and the return pipe 2.
3 is disconnected, the heat source pump 25 is driven, and a flow opposite to that shown in FIG. 1 is generated in the pipe 23. As a result, sufficient heat can be recovered from the heat recovery device 1B.

温水及び冷水の供給は第１図と全く同一であるが季節と
して夏の場合で、冷房負荷と給湯負荷がある場合を示し
ている。この運転モードでは、冷房負荷が多くなるので
その排熱のほうが多くなり熱回収の必要性はなくなる。The supply of hot water and cold water is exactly the same as in FIG. 1, but the season is summer, and there is a cooling load and a hot water supply load. In this mode of operation, the cooling load increases, so more waste heat is produced, eliminating the need for heat recovery.
このためこのモードでは、放熱源２７が必要となる。放
熱源２７は冷却塔、海水、河川水等があり、配管２８．
２９を介して熱が送られる。Therefore, in this mode, the heat radiation source 27 is required. The heat radiation source 27 includes a cooling tower, seawater, river water, etc., and the piping 28.
Heat is transferred via 29.
