The objectives of this research are to develop the welding process of copper tube for refrigeration in air conditioner by using rotation brazing table. The key design is the use of rotary head for nitrogen and rotary head for cooling water in assembly jig nitrogen discharge to prevent the internal welding soot to remove the soot that may occur during welding from piping system and to cool down the profile quickly. The result of water cooling to prevent that damage due to the heat of welding. The result from designing and creating of rotation brazing table to substitute stationary welding found that there is the reduction of machine cost by 11.61% or 46000 Baht/machine reduction of usage space 8.75 square meters or 74375 Baht increase of productivity by 93.48% reduction of nitrogen consumption by 98.20% or 2593 Baht/month reduction of support tool in production 75000 Baht per one rotation brazing table reduction of tiredness from working by 30.24% or equal to 137 manual works per day and reduction of usage of consumable material that can cause of greenhouse gas in form of trash such as cloth glove 1.40 KgCo2 per year leather glove 12.5216 KgCo2 per year nitrogen gas 0.1784 TonCo2 per year and water 0.54 KgCo2 per year. All of these can support the competition and dynamic change of industrial air conditioner in the future sustainably.

The study and Development Lightweight growing media by Coir to use a Vertical garden.To create thermal comfort for building users are the main factors causing the air conditioning. The cause of the electrical consumption. Thus bringing the tree into the building. In the past the building that used tree. Create a homey Subsequently it has adopted a large tree used for the purpose of lowering the temperature of the surrounding buildings. Developed into a roof garden Reduce heat to pass through the roof. And is currently being applied in the manner of a green wall. This helps reduce the heat that enters the building through the building envelope as well. The behavior of the tree to absorb water from the roots to the leaves and then passed to photosynthesis. Such a process makes the water evaporates and the air has been cooled by the surrounding trees The Heat pulled away for the evaporation of water. Such a process which happens from time to time no matter how much humidity in the air. The cool environment is another factor that manipulates the ambient environment to environment and buildings The benefits of trees in the green areas of the city this is helping to reduce and prevent the phenomenon of urban heat island The study and Development Lightweight growing media by Coir to use a Vertical To reduce the weight of structural data were collected to design the plant material. Then the data from design professionals and vertical landscaping questionnaire. And interviews to analyze the result. And amends To test plant material vegetation series of 12 trials by planting vegetation. On the wall a series of three experiments wall. (Width 1.20 m. Height 3.00 m.) Of the test data and the growth of vegetation. Found that plants grow well on a series of plant material. The unit is lightweight and planting is not burdened with the weight of the building structure.

The creation of nightgown decorated by woven silk yarn scrap from Baan Krua Cottage Industrial Village in Ratchathewi Bangkok Thailand. Objectives are: 1) to study the weaving technique using the silk yarn scrap 2) to design a nightgown decorated with woven silk yarn scrap and 3) to study the overall satisfaction of nightgown designs which utilize silk yarn scrap. The sample population in this research is 250 women found on Silom Road central Bangkok. The research instrument is a questionnaire with 9 prototype nightgowns decorated with woven silk yarn scrap. The collection consists of 3 sets one set with 3 short nightgowns another set with 3 long nightgowns and the last set with 3 short nightgowns with long tails. The research methodology is to hand out the questionnaire to 250 non-specific women on Silom Road. Data analysis is done by statistic percentage average and standard deviation. Results of studying the survey show that most of the sample populations are women age between 31 -35 years old with bachelor degrees or the equivalent. Most are married and work as state enterprise officers. Incomes are between 20001 - 30000 baht. Most of them have bought a silk nightgown before and chosen to buy at department stores. The reason that they do not prefer silk nightgowns is because most in the current market are not innovative enough. Most of the sample populations have never seen a nightgown decorated with woven silk yarn scrap before. The results of studying the satisfaction of the sample population found that for the short nightgown set most of the sample population prefer number 2 standard deviation is 4.48. For the long nightgown set most of the sample populations prefer number 2 standard deviation is 4.44. And for the short nightgown with long tail set most of the sample populations prefer number 2 standard deviation is 4.46.
