Hot water heating equipment

温水暖房装置

Abstract

PURPOSE: To provide an equipment capable of preventing the air from stagnating at the upper part of a hot water storage tank, and preventing the generation of an abnormal noise by the local boiling between the trapped air and the water level in a hot water heating equipment where hot water is produced using a hot water storage type heating boiler, and circulated to achieve the heating. CONSTITUTION: A hot water heating equipment is provided with a hot water storage tank 11 of a hot water storage type heating boiler 10, radiators 20, 50 for heating, and a circulating pump 40 and hot water circulating passages 30, 33 to circulate the hot water from the hot water storage tank 11 through the radiators 20, 50 for heating. An auxiliary tank 70 which is arranged at the position higher than the hot water storage tank 11 of the hot water storage type heating boiler 10 is provided in the middle of the circulating passages 30, 33, an air vent tube 80 is connected to the auxiliary tank 70 from the highest position in the hot water storage tank 11, a water level sensor 72 is provided at the prescribed position higher than the connection point of the air vent tube 80 of the auxiliary tank 70, and a controller 100 to stop the combustion of the hot water storage type heating boiler 10 when the water level in the auxiliary tank 70 is lower than the position of the water level sensor 72 is provided.
(57)【要約】 【目的】 貯湯式加熱缶体を用いて温水を作り、循環さ せて暖房を行う温水暖房装置において、貯湯槽の上部に エアーが溜まるのを防止し、エアー溜まりと水面との間 で局部沸騰による異音が発生するのを防止することがで きる装置の提供を目的とする。 【構成】 貯湯式加熱缶体10の貯湯槽11と、暖房用放熱 器20、50と、貯湯槽11からの温水を暖房用放熱器20、50 を経て循環させる循環ポンプ40及び暖房水循環路30、33 とを有する温水暖房装置であって、循環路30、33の途中 に貯湯式加熱缶体10の貯湯槽11の位置よりも高位置に配 置される補助タンク70を設けると共に貯湯槽11内の最上 位置から補助タンク70内にエアー抜き管80を接続し、且 つ補助タンク70のエアー抜き管80の接続位置よりも上位 の一定位置に水位センサ72を設け、補助タンク70の水位 が水位センサ72の位置よりも低くなると貯湯式加熱缶体 10の燃焼を停止するコントローラ100 を設けた。
