Abstract
A storage hot water supplying apparatus provides heated water to a load circuit through which users uses water, and includes a water storage tank which stores water and has outlets for water to be heated at different heights, and an outlet selecting unit to select, from among the outlets, an outlet to take out the water, based on a provision temperature which is a temperature of water to be provided from the water storage tank to the load circuit and temperatures of the water to be taken out through the outlets. A heating unit heats the water taken out through the selected outlet and to be returned to the water storage tank.
Claims15
A storage hot water supplying apparatus which provides a heated water to a load portion through which a user is provided water, the storage hot water supplying apparatus comprising:
- a water storage tank which stores water and is provided with a plurality of water outlets through which the water is taken out for heating, the water outlets being positioned at different levels of the water storage tank and not being used to provide the heated water to the load portion;
- an outlet selecting unit configured to select, from among the water outlets, a water outlet through which to take out the water, based on a provision temperature which is a temperature of water required by and to be provided to the load portion and temperatures of the water to be taken out through the water outlets as detected by respective temperature sensors proximate to each water outlet, the selection of the water outlet being made by sequentially comparing temperatures detected proximate to each water outlet with the provision temperature and selecting the water outlet having a temperature lower than the provision temperature;
- and
- a heating unit configured to heat the water taken out through the selected water outlet and to return the heated water to the water storage tank.
An operation control apparatus for controlling a storage hot water supplying apparatus which provides a heated water to a load portion through which a user uses water,
- the storage hot water supplying apparatus including:
- a water storage tank which stores water and is provided with a plurality of water outlets through which the water is taken out for heating, the water outlets being positioned at different levels of the water storage tank and not being used to provide the heated water to the load portion;
- and
- a heating unit configured to heat the water taken out through the water outlets and to be returned to the water storage tank, and
- the operation control apparatus comprising:
- an outlet selecting unit configured to select, from among the water outlets, a water outlet through which to take out the water, based on a provision temperature which is a temperature of water required by and to be provided to the load portion and temperatures of the water to be taken out through the water outlets as detected by respective temperature sensors proximate to each water outlet, the selection of the water outlet being made by sequentially comparing temperatures detected proximate to each water outlet with the provision temperature and selecting the water outlet having a temperature lower than the provision temperature;
- and
- a heating instruction unit configured to instruct the heating unit to heat the water taken out through the selected water outlet and to return the heated water to the water storage tank.
An operation control method for controlling a storage hot water supplying apparatus which provides a heated water to a load portion through which a user uses water,
- the storage hot water supplying apparatus including:
- a water storage tank which stores water and is provided with a plurality of water outlets through which the water is taken out for heating, the water outlets being positioned at different levels of the water storage tank and not being used to provide the heated water to the load portion;
- and
- a heating unit configured to heat the water taken out through the water outlets and to be returned to the water storage tank, and
- the operation control method comprising:
- selecting, from among the water outlets, a water outlet through which to take out the water, based on a provision temperature which is a temperature of water required by and to be provided to the load portion and temperatures of the water to be taken out through the water outlets as detected by respective temperature sensors proximate to each water outlet, the selection of the water outlet being made by sequentially comparing temperatures detected proximate to each water outlet with the provision temperature and selecting the water outlet having a temperature lower than the provision temperature;
- and
- instructing the heating unit to heat the water taken out through the selected water outlet and to return the heated water to the water storage tank.
A program recorded on a non-transitory computer-readable recording medium for controlling an operation of a storage hot water supplying apparatus which provides a heated water to a load portion through which a user uses water,
- the storage hot water supplying apparatus including:
- a water storage tank which stores water and is provided with a plurality of water outlets through which the water is taken out and heated, the water outlets being positioned at different levels of the water storage tank and not being used to provide the heated water to the load portion;
- and
- a heating unit configured to heat the water taken out through the water outlets and to be returned to the water storage tank, and
- the program causing a computer to execute:
- selecting, from among the water outlets, a water outlet through which to take out the water, based on a provision temperature which is a temperature of water required by and to be provided to the load portion and temperatures of the water to be taken out through the water outlets as detected by respective temperature sensors proximate to each water outlet, the selection of the water outlet being made by sequentially comparing temperatures detected proximate to each water outlet with the provision temperature and selecting the water outlet having a temperature lower than the provision temperature;
- and
- instructing the heating unit to heat the water taken out through the selected water outlet and to return the heated water to the water storage tank.
