る。Description: TECHNICAL FIELD The present invention relates to a hot water supply system for a building having a large number of living rooms such as apartments such as condominiums, hotels, and general buildings, and particularly a hot water supply system effective for high-rise buildings. Regarding
上記のような建築物において台所用、浴室用等の各種
の温水を得る場合、各室ごとに小容量の加熱器を設置す

により温水を得た後、これを各室に供給するといったセ
ントラル給湯システムがとられている。When obtaining various types of hot water for kitchens, bathrooms, etc. in the above buildings, there is a method of installing a small capacity heater in each room, but in general, large capacity heating common to each room A central hot water supply system is used in which hot water is obtained from a water heater and then supplied to each room.

環させ、送り主管に分岐管を接続して各室に導き、各室
において分岐管から直接温水を得るようにしたものがあ
る（第１方式）。In one of the central hot water supply systems, a heater is connected to a closed loop pipe line composed of a main feed pipe and a return main pipe, a pump is installed in this closed loop pipe line to circulate hot water, and a branch pipe is connected to the main feed pipe. There is a system in which hot water is directly obtained from a branch pipe in each room (first method).
他方上記給湯システムの場合、温水が分岐管から排出

が知られている（第２方式）。On the other hand, in the case of the hot water supply system, since hot water is discharged and consumed from the branch pipe, water (usually tap water) must be replenished to the circulation pipe each time, which causes various problems. It is known that a branch pipe leading to each chamber is connected between the feed main pipe and the return main pipe as disclosed in Kaisho 63-1409, and a heat exchanger for hot water for hot water supply is installed in this branch pipe. Yes (second method).
しかしながら近年建築物が高層になり、それに伴って
第1,第２方式いずれの場合も、蛇口、バルブ、計器およ

ストが高価にならざるを得ない。However, in recent years, the building has become high-rise, and in accordance with it, in both cases of the 1st and 2nd methods, it is required that the equipment such as faucets, valves, instruments and heat exchangers, that is, those with a large pressure resistance of the hot water supply load be required. Therefore, the installation cost is inevitably high.

きさとしたものがある。34,44は循環ポンプを示す。Therefore, as shown in FIG. 2 for example, a heat exchanger 40 is conventionally provided at the boundary between the low-rise part and the high-rise part of a building, and the main feed pipe connected to the heater 31 and the heat exchanger 40 is provided in the low-rise part. The first closed loop pipe line 50 consisting of 32 and the return main pipe 33 is installed, and the second closed loop pipe line 60 consisting of the feed main pipe 42 and the return main pipe 43 connected to the heat exchanger 40 is installed in the high rise part, Branch pipe
There is one in which the compressive strength of hot water supply loads 36, 46 connected to 35, 45 is set to a normal size. 34 and 44 are circulation pumps.

となるという問題点があった。However, in this case, although heating is performed by the same heater 31 as the low-rise portion in the high-rise portion, since the heating is performed via the heat exchanger 40, the heating conditions are different from those of the low-rise portion, and therefore the usage conditions of the low-high rise portion are used. In order to make the same (load response, cycle, etc.), the control system of the heater 31 becomes complicated and the cost becomes high.

を安価にすることができるという効果がある。As described above, the present invention is provided between the reference level (L 0 ) and the first set level (L 1 ) higher than the reference level (L 0 ), and the pressure head (H) below the predetermined level at the reference level (L 0 ). Has,
A low-rise first closed loop pipe line (10) provided with a pump;
Reference level (L 0) and the first set level (L 1) higher than the second set level (L 2) and the first set level is provided between the (L 1) at a predetermined less pressure head (H) A hot-closed second closed loop pipe line (20) provided with a pump and at least two pipe lines connected in parallel to the heater (1), and each hot water supply load member (6), The branch pipes (5) and (15) guided to (16) are the second closed loop pipes between the reference level (L 0 ) and the first set level (L 1 ) in the first closed loop pipe line (10). First set level (L 1 ) on road (20)
And the second set level (L 2 ) respectively, so that the first and second closed loop pipe lines (10) and (20) do not interfere with each other and operate independently. On the contrary, when both are operated at the same time, the load generated in the high-rise second closed-loop pipe (20) is not applied to the low-rise first closed-loop pipe (10).
Since the hot water supply load members (6) and (16) in the second closed loop pipelines (10) and (20) receive a substantially uniform load, the hot water supply load members (6) and (16) are substantially the same. With the same specifications with light pressure resistance, the operating conditions of the first and second closed loop pipes (10) and (20) can be made the same, and the heater control system is simple There is an effect that the installation cost can be reduced.
