Bartaria 1 Suraj, ME Scholar, LNCT, Bhopal 2 Dr. V.N. Bartaria, Prof. & Head, LNCT, Bhopal ABSTRACT Floor swirl diffusers used in air-conditioning system can create better air mixing to enhance indoor air quality and help in achieving better human comfort. The variation in temperature in air conditioning system depends strongly on the flow characteristics produced by the diffuser outlet that vary considerably between different modeling set ups. In corporate sector it is very important to calculate the effect of variation in temperature of diffused air from floor swirl diffuser with and without heat load. In this experimental work, I have tried to reduce the variation in temperature of conditioned air and improvement in thermal human comfort by adopting different models of floor swirl diffuser designed on pro-E software. After that I have made prototype wooden model of the floor swirl diffuser to check its performance under different operating and flow conditions experimentally. The experiment has been performed inside an acrylic sheet wooden room of size 4ft x 4ft x 5ft with floor swirl diffuser models installed at the roof. The variation in temperature of diffused air form floor swirl diffuser at different altitude and the effect of heat load on temperature variation is determined. This experiment has been performed on three different models of floor swirl diffuser having different slot angles of 7⁰, 8⁰ and 9⁰. Keywords: ACE-Air Change Effectiveness, Heat Load Capacity, Swirl motion, 7⁰ Swirl Diffuser- Diffuser having slot with draft angle 7⁰, 8⁰ Swirl Diffuser- Diffuser having slot with draft angle 8⁰, 9⁰ Swirl Diffuser- Diffuser having slot with draft angle 9⁰,and Round and rectangular slots, Cross- section.

For floor-level air supply systems, swirling diffusers are most widely used. Modeling of the diffuser plays an important role in predicting airflow pattern in the room. Swirl diffusers are generally mounted into the underfloor air handling space. This device delivers conditioned air at floor level to the space and allows the occupant to manually control both the volume and direction of the air flow. The diffuser is constructed of a durable, high impact, polycarbonate material. Delivering air from the floor has an advantage of supplying fresh, cool, clean air directly into the occupied zone of the space, so heat and pollutants are not continuously circulated within the space as it happens in an overhead air distribution system. It will results in dissipation of heat and less concentration of pollutants in the occupied space in the lower level than those at the upper levels of the space. Ventilation is done through displacement as opposed to dilution. The requirement of a good air distribution system is to supply clean and fresh air with less variation in temperature with height and different locations to provide thermal comfort and high air quality. In Asian and European countries, 30-50% of occupants have health problem because of bad air distribution system. Almost 30-40% of the energy produced has been spent on air distribution system in most of the developing countries. Swirl diffusers are designed to provide effective indoor air diffusion through specially designed swirl deflection blades to produce a highly turbulent radial air flow pattern that will induce better mixing of room air. This also results in rapid temperature equalization to give stable room conditions with minimum temperature gradients. The excellent high qualities of air from swirl diffusers enable designers to aim for a high value of Air Change Effectiveness (ACE). Swirl diffusers have recently become very popular because they generate radially high induction swirl air flow by drawing room air up into the supply air pattern to induce superior air mixing. Better mixing means better ACE. It is therefore required to study the characteristics of air distribution system with floor swirl diffuser under different operating and flow conditions with high thermal load. EXPERIMENTAL SET-UP It consists of an acrylic sheet wooden room of size 4ft x 4ft x 5ft with different models of swirl diffuser installed at the floor level. The conditioned air from air conditioner is supplied from the bottom through a duct of reducing cross-section to increase the air flow velocity through the diffuser. A heater of 1500W is placed inside the room to provide a heat load. Heater is placed near the location Y2. A temperature sensing instrument with six thermocouple wires is placed inside the room to measure the temperature at six locations vertically at a distance of 0.7 feet. There are four exhaust vents at the top surface of the wooden block through which ventilation is carried out inside the room. There are six locations at the floor inside the room where readings of temperature have to be noted and the variation in temperature of air is to be studied. 3-D view of the experimental set-up and actual front view of the experimental set-up is shown in Fig.1 and Fig.2 respectively.

Locations are taken along X-axis and Y-axis on the floor. These locations are equally spaced and are at a distance of 1 foot from each other. The supply air temperature from the air-conditioner is 18.4⁰C at a flow rate of 0.2m3 /s. The heat load is applied inside the room with the help of heater of load capacity 1500W. Various temperature readings are noted at location Y1, Y2, Y3, X1, X2 and X3 with load and without load. The experiment has been performed with all three models of diffuser. These experimental results will help us in comparing the performance of three different models of floor swirl diffuser under different operating and flow conditions. These results have been plotted graphically between temperature and height from the floor level. It will also provide the designers a guideline in achieving better human comfort and best performance with floor swirl diffuser used in air conditioning system. The graphs plotted between temperature and height at various locations indicates that variation in temperature with height is less with 8⁰ swirl diffuser. The result also shows that variation in temperature reduces as we move away from the heat source. Due to swirl action produced by the

During the experiment performance only one exhaust vent is opened out of the four. We can also perform the same experiment with all the four vents are opened. The variation in temperature at location Y1, Y2 and Y3 is comparatively more than at location X1, X2 and X3 during presence of heat load. This happens due to presence of heat source at location Y2. AIR TEMPERATURE MEASUREMENT Air temperature is measured spontaneously at each location under different operating conditions. Inlet and return air temperature are 18.4⁰C and 23.6⁰C for 7⁰ swirl diffuser, 18.4⁰C and 22.4⁰C for 8⁰ swirl diffuser and 18.4⁰C and 23.8⁰C in case of 9⁰ swirl diffuser respectively. A uniform temperature distribution is observed. The highest temperature gradient is found at location Y2. In the upper occupied zone there is small temperature gradient due to good mixing of air in the upper region. The temperature at various locations is tabulated and the graphical results are shown below.

It helps us in comparing the performance of three different types of swirl diffuser under different operating and flow conditions. Due to swirl action produced more unidirectional flow was created, the slow recirculation at the occupant zone was eliminated for the floor-supply ventilation and the risk of cross contamination can be effectively reduced. The system with the swirl diffusers can provide a better comfort level than that with the perforated panels due to the mixing by the diffusers. This study helps in selecting optimum models for floor swirl diffuser under different operating conditions. We can improve the Air Change Effectiveness and human comfort by varying the slot design angle of diffuser. It will results in better mixing of air inside the room and the variation in temperature of air from floor height will be reduced. We can achieve better human comfort and proper ventilation by using floor swirl diffuser.
