Storage type hot-water supply device

Abstract

<P>PROBLEM TO BE SOLVED: To provide a storage type hot-water supply device capable of reducing reheating operation during daytime for improving economic efficiency while improving COP. <P>SOLUTION: The storage type hot-water supply device includes a temperature rising control part 47 for executing either reheating operation or hot-water pouring operation when raising the temperature of water in a bathtub 6. The temperature rising control part 47 includes a temperature distribution forecasting means 48 for forecasting temperature distribution of warm water in a hot-water storage tank 2 after the reheating operation, a reheating condition setting means 49 for setting reheating starting conditions for starting the reheating operation during daytime, and a reheating determination means 50 for determining whether the reheating operation is to be performed or not based on the temperature distribution forecasted by the temperature distribution forecasting means 48 and the reheating starting conditions set by the reheating condition setting means 49. When the reheating determination means 50 determines that the reheating operation is to be performed when raising the temperature of the water in the bathtub 6, the temperature rising control part 47 makes the device perform the hot-water pouring operation. <P>COPYRIGHT: (C)2009,JPO&INPIT
【課題】昼間時間帯の沸き増し運転を低減させ経済性を向上させると共に、COPを向上させる貯湯式給湯装置を提供する。 【解決手段】浴槽6内の浴槽水の昇温時に、追い焚き運転か差し湯運転のどちらかを行わせる昇温制御部47を備えた貯湯式給湯装置において、昇温制御部47は、追い焚き運転後の貯湯タンク2内の温水の温度分布を予測する温度分布予測手段48と、昼間時間帯に沸き増し運転を開始する沸き増し開始条件を設定する沸き増し条件設定手段49と、温度分布予測手段48により予測された温度分布と沸き増し条件設定手段49により設定された沸き増し開始条件とに基づいて、沸き増し運転が行われるかどうかを判定する沸き増し判定手段50とを有し、昇温制御部47は、浴槽6内の浴槽水の昇温時に、沸き増し判定手段50により沸き増し運転が行われると判定された場合には、差し湯運転を行わせるようにした。 【選択図】 図3
