Now a day the mostly air condition are use vapor compression refrigeration system in which R-22 refrigerant is used as a working substance. From the results of study it found that the quantity of water vapor or moisture in the air is condensed with in the fan coil unit while through out the evaporator. The fluid after condense is called condensed water. By this process the quantity of condensed water is increases when the air condition is used in the long time. To increase the utility the condensed water is recovered for the heart reduction in the finned-tube condenser. The experiment is consist of two conditions by using the air and condensed water to heart reduction. But in case of condensed water the pressure operation is controlled at 280 and 260 Psig respectively. The results of experiment shown the refrigeration effect coefficient of performance (C.O.P) and energy efficiency ratio (EER) is 39675 Btu/hr 3.01 and 10.3 Btu/hr.Watt respectively with the air is used. At the pressure operation 280 Psig refrigeration effect (C.O.P) and (EER) is 44212 Btu/hr 3.38 and 11.5 Btu/hr.Watt respectively and 49856 Btu/hr 3.99 and 13.6 Btu/hr.Watt at pressure operation 260 Psig. Furthermore the capacity of condenser is increases to 11.43% and 25.6% and also the refrigerant efficient is increases to 12.43% and 32.43% at the pressure operation 280 and 260 Psig. Thus the parameter of the energy efficiency ratio depends on the capacity of condenser working substance temperature (pressure operation) and air surrounding temperature.

Nitrogen is an essential nutrient for plant growth. When the plants have been grown for a long-term effect to decreased nitrogen in soil and insufficiency of the plant growth. One biological method for increasing the nitrogen content in soil is utilize of free nitrogen-fixing bacteria Azotobacter. Therefore the objective of this research was to search natural material suitable for Azotobacter fixation. The 10 natural materials were observed physical structure and investigated the ability of natural materials for Azotobacter fixation. The results showed that water hyacinth and bagasse stalks were fixed the Azotobacter of 2.43x108 and 1.94 x108 CFU per gram of each natural material respectively. After that the selected fixed Azotobacter of water hyacinth and bagasse stalks were studied the growth of Brassica Chinensis. This experiment was designed to 4 treatments. The first treatment was mixed of water hyacinth stalks and the Azotobacter. Second treatment was mixed of bagasse stalks and the Azotobacter. The third treatment was the Azotobacter only. The last treatment was soil only. The results indicated that the average of plant growth include height leaf number root length fresh weight and dry weight of the mixed of water hyacinth stalks and the Azotobacter had significantly higher growth rates than other treatments. The total nitrogen was also increased 1.4 fold in the soil. All results suggest that the water hyacinth stalk is alternative for the fixation of the free nitrogen-fixing bacteria Azotobacter as induce nitrogen in the soil and plant growth promotion.

Vegetable Growing System has an absolute requirement of nutrients and minerals. The microbial application can facilitate in addressing limited access to chemical fertilizer concerns. Moreover the photosynthetic microorganism community can contribute together in nutrient availability for plant growth. This research aims to develop an automatic hydro-organic vegetable growing system. Moreover the analytical of photosynthetic microorganism growth rate in fermented juice was also observed within three months in terms of temperature pH electroconductivity total dissolved solids mixed liquor suspended solids and phosphorus. The efficiencies of an automatic hydro-organic vegetable growing system were also monitored along an experimental period (45 days of operation optimization). The vegetable growth rate was observed in terms of leaf length leaf width and root length. These experimental results showed that the phototrophic growth of photosynthetic microorganisms should the main bacterial activity at daytime operation and vegetables could grow by using fermented juice. The photosynthetic microorganism concentration and nutrients concentration in fermented juice was significant to promote the productivity of vegetable growing which the photosynthetic biomass is rich in proteins and vitamins. Besides this system can be easily applied and also very cost-effective for agricultural practice and frequent maintenance every experimental run was necessary.

This study aims to 1) Product development of hand washing liquid soap smell Thai perfume 2) Physical and chemical properties Product of liquid soap hand wash smell Thai perfume and3) Consumer satisfaction survey on smell Thai perfume hand washing liquid soap products A questionnaire on consumers behaviors related to OTOP products was conducted. And smell test to choose the most acceptable smell. With 30 guests There were 3 levels of odor in liquid soap: 0.2 percent 0.5 percent and 0.8 percent. With 5 experts Experimental plot design RCBD (Randomized Complete Block Design) The 9-tailed test was used (9–point Hedonic scale) with sensory tests and use percentage statistics. With Acceptance and satisfaction test and physical properties viscosity color and chemical analysis of alkalinity were analyzed. 100 people were tested for satisfaction. The results indicate that most consumers are mostly female. Think 73.3 percentage. The behavior of consumers in using smell Thai perfume. Liking smell Thai perfume flower scent it thinks 90 percentages. bottle filling 100 cc it think53.3 percentages. And the smell that is most liked is the smell of Pip flowers. The average level of smell is very similar. At the rate of replacement liquid soap to smell the smell Thai perfume. The highest score was the formula 2 /0.5 percentage. Physical Properties of Viscosity stability at 527.4 Point Centrino it is liquid stability on surface very gool. Color values have average brightness (L*) green values (a*) and blue values (b*) is equal to 16.47. The liquid soap is greenish yellow. Chemical qualities in acidity it was found that the pH value was 5-8 (6.20 ± 0.01). Followed by product standards community. Consumers are satisfied with liquid soap products with smell Thai perfume like 50.1 percent in terms of color intensity like 35 percent Is the sole of liquid soap like 62 percent Medium scent like 44 percent Medium Concentration like 69 percent finally not irritating to the skin like 98 percent.
