1. Introduction.

This work had two objectives: student evaluation; sizing of the ACADS air conditioning system. Some important results were found, on the context of the ACADS project. The variable air volume control – VAV - is the better solution on HAVC energy consumption because the electric power required by the supply fan varies with the cube of the fan rpm. The fresh air supplied to each person is about 8 liters/s. Hence if a space has 308 seats we have 308 * 8 liters/s of air supply on a CAV – constant air volume control – system. But on an ACADS (VAV optimization) system we will have a variable air volume that supplies air only to the real room occupancy. As the room occupancy diminishes, also the air supply and fan electric power diminishes. The VAV control operates based on the temperature sensor. The ACADS control adds to the temperature sensor the room occupancy information – ticket service. The Fan rotation is controlled by the occupancy information, and the cooling/heating coil is controlled by the temperature sensor, to make corrections and maintain the temperature set point. The program simulates and establishes the best system operation scheduling from the information gathered from the people, light and thermostat scheduling. But these schedules vary on the real life by a great set of factors. Hence if the real system automation doesn’t take this in to account the best results are impossible to accomplish. In real life this problem is solved by the ACADS solution

2. Work Description

The work was divided in three steps: Input data to the Carrier HAP – Hourly Analysis Program; Sizing of the HVAC components; System simulation. These three steps were executed on the same program. The next step is the equipment selection and installation by the HAVC company service – from the project (specifications) final report. Future energy analysis will be made on the solar radiation gains to heat the cinema room (see last append).

3. Input Data

3.1. Local Weather

The first data to be transferred in to the HAP program was the information about geographical location of the building, the nature of local time and soil properties. Parameters like the temperature, humidity and solar radiation conditions are central to the sizing and simulation processes. Two distinct kinds of weather data exist:

3.1.1. Design Weather Data

Used to perform cooling and heating design load estimates (see append A).

3.1.2. Simulation Weather Data

Required to perform 8760 hour energy simulations. Results of these simulations were used to compute annual energy use and energy.

3.2. Cinema Theatre Space

The cinema space must be defined so system design calculations or energy simulations can be performed. A space consists of a number of walls, roofs, windows and internal heat gains that influence heat transfer into and out of the space (see append B)

3.3. Schedules

Schedules define the hourly and daily behavior of the characteristics of a building and its HVAC equipment. Each profile contains data for one 24 hour period and are assigned to the different days of the week and months of the year (see append L).

3.4. Systems

The components included on the program were fans, coils, ductwork, supply terminals and controls. Also when performed the energy analysis of other components like heat pumps, electric resistances and combustion heating components the information collected from there were considered by the program (see append C).

3.5. Plants

A Plant is the equipment and controls which provide chilled water to cooling coils, or hot water or steam to heating coils. Examples include chiller plants, hot water boiler plants and steam boiler plants (see append D).

4. Sizing

This is a calculation process to determine the equipment specifications like airflow rates, supply terminal characteristics and coil capacities for HAVC systems (see append E).

5. Simulations System simulation reports provide information about system and plant operation and energy use during a typical year (see append F, G, H, I).

6. Results The simulation results and benchmarking were made only for cooling (this is a Carrier Developed Program). The results are described for each component: Supply Fan:

• CAV (Constant Air Volume); Floor Air Supply: 2403,5 €/year; • CAV (Constant Air Volume); Ceiling Air Supply: 1998,6 €/year (16,85 % less); • VAV (Variable Air Volume); Floor Air Supply: 261,1 €/year (89,14 % less ); • VAV (Variable Air Volume); Ceiling Air Supply: 213,1 €/year (91,13 % less );

Chiller Plant:

• CAV (Constant Air Volume); Floor Air Supply: 684,8 €/year; • VAV (Variable Air Volume); Ceiling Air Supply: 423,5 €/year (38,16 % less); • CAV (Constant Air Volume); Ceiling Air Supply: 415,1 €/year (39,38 % less); • VAV (Variable Air Volume); Floor Air Supply: 333,3 €/year (51,33 % less );

Final Results:

• CAV (Constant Air Volume); Floor Air Supply: 3088,3 €/year; • CAV (Constant Air Volume); Ceiling Air Supply: 2413,7 €/year (21,84 % less); • VAV (Variable Air Volume); Ceiling Air Supply: 636,6 €/year (79,39 % less ); • VAV (Variable Air Volume); Floor Air Supply: 594,4 €/year (80,75 % less );

Also it’s important to compare the loads between cooling and heating coils: Cooling Coil Loads:

• CAV; Floor Air Supply: 16709 kWh / year 3088,3 €/year; • VAV; Ceiling Air Supply: 6515 kWh / year 423,5 €/year; • CAV; Ceiling Air Supply: 9431 kWh / year 415,1 €/year; • VAV; Floor Air Supply: 5703 kWh / year 333,3 €/year.

Heating Coil Loads:

• CAV; Floor Air Supply: 35055 kWh / year • VAV; Ceiling Air Supply: 0 kWh / year (Not Simulated) • CAV; Ceiling Air Supply: 57783 kWh / year • VAV; Floor Air Supply: 0 kWh / year (Not Simulated)

7. Conclusion

On the last paragraph the best results presented are those of the variable air volume control applied to the air supply fan. The energy consumption reduction is enormous on the fan electric motor component when compared to the rest of the HAVC components. Thus the best solution for this type of spaces is the VAV control. This solution increase on importance with the space volume. Other advantages are the noise reduction and improve the life cycle.
