Description

本発明は、暖房熱媒を加熱する熱源機と暖房熱媒の熱を利用して暖房する暖房端末の間で暖房熱媒を循環させる循環回路を備えた暖房システムに関する。 TECHNICAL FIELD The present invention relates to a heating system having a circulation circuit for circulating a heating heat medium between a heat source device that heats the heating heat medium and a heating terminal that performs heating using the heat of the heating heat medium.

従来から、例えば特許文献１のように、暖房熱媒を加熱する熱源機と暖房端末の間で暖房熱媒を循環させて暖房を行うと共に、この暖房熱媒の熱を利用して給湯を行う暖房給湯装置を備えた暖房システムが知られている。このような暖房システムは、１台の熱源機で暖房熱媒を加熱するので、複数の暖房端末を備えた場合には各暖房端末に同じ温度の暖房熱媒が分配供給されることになる。それ故、例えば温風暖房機のように高温の暖房熱媒を要求する暖房端末と、床暖房装置のように低温の暖房熱媒を要求する暖房端末を混在させることが困難である。 Conventionally, for example, as in Patent Document 1, heating is performed by circulating a heating heat medium between a heat source device that heats the heating heat medium and a heating terminal, and hot water is supplied using the heat of this heating heat medium. Heating systems with heating and water heaters are known. In such a heating system, a single heat source device heats the heating medium, so when a plurality of heating terminals are provided, the heating medium having the same temperature is distributed and supplied to each heating terminal. Therefore, it is difficult to coexist with a heating terminal that requires a high-temperature heating medium, such as a warm air heater, and a heating terminal that requires a low-temperature heating medium, such as a floor heater.

一方、異なる温度の暖房熱媒を供給するために、例えば特許文献２のように、複数の熱源機を備えることにより、高温の暖房熱媒を要求する暖房端末と低温の暖房熱媒を要求する暖房端末に、要求される温度の暖房熱媒を同時に供給可能なように構成された暖房システムが知られている。 On the other hand, in order to supply heating heat medium of different temperatures, for example, as in Patent Document 2, by providing a plurality of heat source equipment, a heating terminal requiring a high temperature heating heat medium and a low temperature heating heat medium are required. A heating system is known that is configured to simultaneously supply a heating medium at a required temperature to a heating terminal.

循環往き通路部１５は、熱源機戻り通路部１３との接続部から暖房通路５ａ，５ｂに接続される接続部１５ａ，１５ｂに至る２つの通路に分岐され、循環往き通路部１５の内部を２つの通路に仕切る仕切壁１５ｅを備えている。また、循環往き通路部１５はパージポート１５ｆを備えている。仕切壁１５ｅは、循環往き通路部１５が例えば銅管であればその内部に挿入した銅板をロウ付け等により固定して形成され、循環往き通路部１５が合成樹脂管であれば例えば射出成形により管内部に一体的に形成される。 The forward circulation passage portion 15 is branched into two passages from a connection portion with the heat source unit return passage portion 13 to connection portions 15a and 15b connected to the heating passages 5a and 5b. It is equipped with a partition wall 15e that partitions into two passages. In addition, the circulation forward passage portion 15 is provided with a purge port 15f. The partition wall 15e is formed by brazing or otherwise fixing a copper plate inserted into the interior of the circulation passage portion 15, for example, if it is a copper pipe, or by injection molding, for example, if the circulation passage portion 15 is a synthetic resin pipe. It is integrally formed inside the tube.

熱源機戻り通路部１３と循環往き通路部１５の接続部には、仕切壁１５ｅによって分岐された循環往き通路部１５が熱源機戻り通路部１３に夫々連通するように、開口部１５ｇが形成されている。この開口部１５ｇは、分岐された循環往き通路部１５に夫々連通する開口面積を異ならせるように、仕切壁１５ｅによって分けられている。 An opening 15g is formed at the connecting portion of the heat source machine return passage portion 13 and the circulation going passage portion 15 so that the circulation going passage portion 15 branched by the partition wall 15e communicates with the heat source machine return passage portion 13 respectively. ing. The opening 15g is divided by a partition wall 15e so that the opening areas communicating with the branched circulation passages 15 are different.

例えば高温側の暖房通路５ａに接続される接続部１５ａに連なる側の開口面積を、低温側の暖房通路５ｂに接続される接続部１５ｂに連なる側の開口面積よりも大きくして、熱源機２で加熱された暖房熱媒を高温側に多く供給可能なようにしている。このように仕切壁１５ｅによって開口部１５ｇの開口面積を異ならせるように構成された熱源機戻り通路部１３と循環往き通路部１５の接続部が、熱源機２で加熱された暖房熱媒を暖房通路５ａ，５ｂに分配する第１分配手段７に相当する。 For example, the opening area on the side connected to the connection portion 15a connected to the heating passage 5a on the high temperature side is made larger than the opening area on the side connected to the connection portion 15b connected to the heating passage 5b on the low temperature side. It is possible to supply a large amount of the heating heat medium heated by to the high temperature side. In this way, the connecting portion between the heat source return passage portion 13 and the circulating going passage portion 15, which is configured such that the opening area of the opening portion 15g is varied by the partition wall 15e, transfers the heating heat medium heated by the heat source device 2 to the heating medium. It corresponds to the first distribution means 7 for distribution to the passages 5a and 5b.

バイパス通路部１６は、仕切壁１５ｅによって分岐された循環往き通路部１５に夫々接続されている。仕切壁１５ｅは、循環往き通路部１５の通路断面積を不均等に分け、バイパス通路部１６を流通する低温の暖房熱媒を分岐された循環往き通路部１５に分配する。このように仕切壁１５ｅによって循環往き通路部１５の通路断面積を不均等に分けるように構成された循環往き通路部１５とバイパス通路部１６の接続部が、バイパス通路部１６を流れる暖房熱媒を暖房通路５ａ，５ｂに分配する第２分配手段８に相当する。 The bypass passages 16 are connected to the circulation going passages 15 branched by the partition wall 15e. The partition wall 15e divides the passage cross-sectional area of the forward circulation passage portion 15 unevenly, and distributes the low-temperature heating medium flowing through the bypass passage portion 16 to the forward circulation passage portion 15 branched. In this way, the connecting portion between the forward circulation passage portion 15 and the bypass passage portion 16, which is configured to unequally divide the passage cross-sectional area of the forward circulation passage portion 15 by the partition wall 15e, serves as the heating heat medium flowing through the bypass passage portion 16. to the heating passages 5a and 5b.

また、熱源機戻り通路部１３から分配されて導入される高温の暖房熱媒とバイパス通路部１６から分配されて導入される低温の暖房熱媒が、分岐された循環往き通路部１５の夫々の通路内を流通する間に混合される。これら分岐された循環往き通路部１５が、第１，第２分配手段７，８で分配された互いに対応する暖房熱媒を混合する混合手段９ａ，９ｂに相当する。尚、熱源機戻り通路部１３と循環往き通路部１５の接続部、及び循環往き通路部１５とバイパス通路部１６の接続部が近接するので、それら接続部近傍で発生する乱流等によって分岐された循環往き通路部１５の一方から他方への暖房熱媒の混入が生じる虞があるが、これを防ぐために仕切壁１５ｅがバイパス通路部１６内に延びていてもよい。 Further, the high-temperature heating medium distributed and introduced from the heat source unit return passage portion 13 and the low-temperature heating medium distributed and introduced from the bypass passage portion 16 are supplied to the branched circulation forward passage portion 15. They are mixed while flowing through the passage. These branched circulation passages 15 correspond to the mixing means 9a, 9b for mixing the corresponding heating mediums distributed by the first and second distribution means 7, 8 respectively. In addition, since the connecting portion between the heat source return passage portion 13 and the circulation going passage portion 15 and the connecting portion between the circulation going passage portion 15 and the bypass passage portion 16 are close to each other, the turbulent flow and the like generated in the vicinity of these connecting portions cause branching. However, the partition wall 15e may extend into the bypass passage 16 to prevent this.

ヘッダー部材１１では、熱源機戻り通路部１３から供給される熱源機２で加熱された高温の暖房熱媒が第１分配手段７により分配され、バイパス通路部１６から供給される暖房に利用された低温の暖房熱媒が第２分配手段８により分配される。第１，第２分配手段７，８により分配された高温の暖房熱媒と対応する低温の暖房熱媒が混合手段９ａ，９ｂによって混合されて、例えば混合手段９ａで高温側の第１の中間温度の暖房熱媒が生成され、混合手段９ｂで低温側の第２の中間温度の暖房熱媒が生成される。 In the header member 11, the high-temperature heating medium heated by the heat source machine 2 supplied from the heat source machine return passage portion 13 is distributed by the first distribution means 7 and used for heating supplied from the bypass passage portion 16. A low-temperature heating medium is distributed by the second distribution means 8 . The high-temperature heating medium distributed by the first and second distribution means 7 and 8 and the corresponding low-temperature heating medium are mixed by the mixing means 9a and 9b, for example, by the mixing means 9a to produce a first intermediate heat medium on the high temperature side. A heating heat medium having a temperature is generated, and a heating heat medium having a second intermediate temperature on the low temperature side is generated by the mixing means 9b.

仕切壁１５ｅによって定まった開口面積の比と通路断面積の比と、暖房通路５ａ，５ｂの夫々の暖房熱媒の流量と、バイパス通路部１６の暖房熱媒の温度と熱源機戻り通路部１３の暖房熱媒の温度等によって、生成される第１，第２の中間温度が定まる。それ故、ヘッダー部材１１を備えた暖房システム１では、ポンプ４ａ，４ｂの流量や熱源機２の加熱目標温度を調整することによって、暖房通路５ａ，５ｂに供給する暖房熱媒の温度を調整可能である。 The opening area ratio and the passage cross-sectional area ratio determined by the partition wall 15e, the flow rate of the heating heat medium in the heating passages 5a and 5b, the temperature of the heating heat medium in the bypass passage portion 16, and the heat source machine return passage portion 13 The first and second intermediate temperatures to be generated are determined by the temperature of the heating heat transfer medium. Therefore, in the heating system 1 including the header member 11, the temperature of the heating medium supplied to the heating passages 5a and 5b can be adjusted by adjusting the flow rate of the pumps 4a and 4b and the heating target temperature of the heat source device 2. is.

The heat of the heat medium is used for heating. At this time, since the corresponding heating mediums distributed by the first and second distribution means 7 and 8 are mixed by the mixing means 9a and 9b, the mixed heating mediums can be supplied to the heating terminals 3a and 3b, respectively. can be supplied to each of the heating terminals 3a and 3b, and the heating heat medium adjusted to the required temperature can be supplied.
