Table 6 shows configuration and combination of equipment system that was designed empirically based on the entire demand of
the primary energy predicted by TRNSYS. When compared with
the optimal design, two units of the AR in high capacity of cooling and heating supply (130 USRT), rather than two units of the HP
in a relatively low capacity (10 hp), were used for cooling supply
in empirical design. As equipment for heating supply, two units
of the GB in the identical capacity (87 kW) and one unit of the
HP (25 hp) were selected. They were found to have relatively low
capacity compared to the equipment selected based on the optimal design. As the case with cooling supply, two units of the AR for
cooling and heating supply were found to be in operation to make
up for insufficient cooling supply. For hot water heating supply in
the optimal design, one unit of the GB in a relatively low capacity
and two units of the HP were selected. However, in the empirical
design, one unit of the GB in high capacity (151 kW) and one unit
of the HP in high capacity (25 hp) were used for hot water heating
supply. For electric supply, one unit of the PV (500 m2) only was
used just as the case with the optimal design.
Representing days of each season (January 15, April 15 and
August 15) were assumed to be the day when energy load such
as cooling energy and heating energy was expected to be at the
maximum. Fig. 8 shows 24-h operation plan for hot water heating
supply, cooling supply, heating supply, and electric supply by representing day of season for the system that was optimally designed,
following the design process of equipment system for energy saving.
In operation of hot water heating supply in the summer, one unit
of the HP in the capacity of 16 hp was basically used for hot water
heating supply. One unit of the HP in the capacity of 10 hp was
additionally operated starting from around 5 pm when hot water
use started to increase. And one unit of the GB in the capacity of
58 kW was simultaneously used for hot water heating supply at
around 9 pm when hot water use reached its peak (Fig. 8(a)). For
hot water heating supply in the middle season, the same kind of
equipment system in the same capacity as the one for the summer
was operated. However, as hot water use increased relatively in the
morning compared to the summer, one unit of the HP in the capacity
of 10 hp was found to be in operation additionally in the morning
(Fig. 8(b)). In the winter, the same kind of equipment system in the
same capacity as the one for the summer and the middle season
was operated while one unit of the HP in the capacity of 10 hp was
additionally operated in the morning and the daytime when hot
water use increased (Fig. 8(c)).
For cooling supply in the summer, two units of the HP in low
capacity (16 and 25 hp) were operated in the early morning when
cooling energy demand was relatively low. At other times, one
unit of the TR (230 USRT) was found to satisfy the cooling energy
demand (Fig. 8(d)).
