Abstract
Description
本発明は、温度制御が簡便になるとともに、安全性に優れ、省エネ効果にも優れた温度制御方法に関するものである。 The present invention relates to a temperature control method that is simple in temperature control, excellent in safety, and excellent in energy saving effect.
パイプ管内に水やオイル等の液体を循環させて温度を制御する方法は、様々な分野で採用されている。
例えば、温水式の床・壁暖房システムにおいては、空間内を暖房するため、床や壁にパイプ管をはりめぐらせ、該パイプ管内に温水等の液体を循環させる方法が採用されている。
また、自動車、電車、船舶、航空等の動力装置や、製鉄、プラスチック等の製造装置、あるいは種々の熱処理装置においても、温度上昇による故障等を防ぐため、パイプ管を用いて冷却水等の液体を循環させる方法が採用されている。
近年では、パソコン等の電子機器などにおいても、パイプ管を用いて冷却水等の液体を循環させるなど、様々な用途で、パイプ管を用いた温度制御方法が採用されている。
A method of controlling the temperature by circulating a liquid such as water or oil in a pipe pipe has been adopted in various fields.
For example, in a hot water type floor / wall heating system, in order to heat the space, a method of circulating a pipe such as hot water around the floor or wall and circulating a liquid such as hot water is adopted.
In addition, in power equipment for automobiles, trains, ships, aviation, etc., steel manufacturing equipment, plastic manufacturing equipment, and various heat treatment equipment, liquids such as cooling water using pipe pipes are used to prevent failures due to temperature rise. The method of circulating is adopted.
In recent years, a temperature control method using a pipe pipe has been adopted in various applications such as circulating a liquid such as cooling water using a pipe pipe in electronic devices such as personal computers.
このような温度制御方法では、温度制御の効率を上げるため、用いるパイプ管は、熱伝導に優れる金属製のものが多く採用されている。また、温度制御の効率を上げるため、躯体とパイプ管は接するように配置されているものが多い。
例えば、温水式床暖房においては、パイプ管は予めコンクリートやモルタル等の床材に埋め込まれて用いるタイプが多く採用されている。
このような温水式床暖房においては、昼夜問わず長期間循環し続けるものが多く、床材自体が常に蓄熱された状態であり、パイプ管の種類等に関わらず、急激な温度変化が少なく、また温度ロスも少なく、電源のＯＮ・ＯＦＦなどによるエネルギー消費量等も、それほど問題視されることはなかった。
In such a temperature control method, in order to increase the efficiency of temperature control, many pipes made of metal excellent in heat conduction are employed. Further, in order to increase the efficiency of temperature control, the casing and the pipe tube are often arranged so as to contact each other.
For example, in hot water type floor heating, a pipe pipe is often used by being embedded in a floor material such as concrete or mortar in advance.
In such warm water type floor heating, there are many things that continue to circulate for a long time regardless of day and night, the flooring itself is always in a stored state, and there is little rapid temperature change regardless of the type of pipe pipe, In addition, there was little temperature loss and energy consumption due to power ON / OFF etc. was not considered as a problem.
しかし近年、温水式床暖房が普及しはじめるにつれ、簡易式のパネル型温水式床暖房が登場し、夜の短期間だけ暖房したり、ある部分だけ部分暖房するタイプが現れ、電源ＯＮ時から、より短い時間で目的とする温度に到達できる床暖房システムが望まれるようになってきた。さらに、人々のエコ環境意識の高まりにより、より安全で、より省エネ効果の高い製品が望まれるようになってきた。 However, in recent years, as hot water floor heating has begun to spread, simple panel type hot water floor heating has appeared, and there are types that heat only for a short period of time or partially heat only at night, and when the power is turned on, A floor heating system that can reach a target temperature in a shorter time has been desired. Furthermore, people's awareness of the eco-environment has increased the desire for safer and more energy-saving products.
そのような状況下、温水式床暖房システムにおいては、次のような問題が挙げられる。
素早く暖房するためには、床材自体の暖房など必要以上に温度を放出しなければならず、特に、パネル型温水式床暖房においては温度ロスが多くなるため、エネルギー消費量も問題になることがある。
さらに、床材とパイプ管が接している部分において、パイプ管近傍の急激な温度変化により、パイプ管近傍の床材が急激に温度変化を起こし、床材の温度ムラの問題や、場合によっては低温火傷等の危険の恐れがある。
Under such circumstances, there are the following problems in the hot water type floor heating system.
In order to heat quickly, it is necessary to release the temperature more than necessary, such as heating the flooring itself, and especially in panel type hot water type floor heating, the temperature loss increases, so energy consumption is also a problem. There is.
Furthermore, in the part where the flooring and the pipe pipe are in contact, the temperature change in the vicinity of the pipe pipe suddenly changes due to the rapid temperature change in the vicinity of the pipe pipe, and the problem of temperature unevenness of the flooring, and in some cases There is a risk of low temperature burns.
このような問題に対し、例えば特許文献１では、温水式床暖房において、温水パイプの間の空間部に、蓄熱部材を配置する方法が記載されている。
しかし、特許文献１のように蓄熱部材が多い場合、電源ＯＮ時に、本来なら床表面へと移動する熱が蓄熱部材へと移動し、床表面の暖房が遅れる、という問題があった。また、蓄熱部材が多くても、それに似合う蓄熱効果は発揮されない問題もあった。
For example, Patent Document 1 discloses a method for disposing a heat storage member in a space between hot water pipes in a hot water type floor heating system.
However, when there are many heat storage members as in Patent Document 1, there is a problem that when the power is turned on, the heat that originally moves to the floor surface moves to the heat storage member and the heating of the floor surface is delayed. Moreover, even if there were many heat storage members, there existed a problem that the heat storage effect which suits it was not exhibited.
このような問題に対し、本発明者らが鋭意検討を行った結果、パイプ管近傍の急激な温度変化を抑えるとともに、パイプ管内の液体を目的の温度とするためのエネルギー消費を抑えることができる、温度制御方法を見出し、本発明の完成に至った。 As a result of intensive studies by the present inventors on such a problem, it is possible to suppress a rapid temperature change in the vicinity of the pipe pipe and to suppress energy consumption for setting the liquid in the pipe pipe to a target temperature. The present inventors have found a temperature control method and have completed the present invention.
