  • Migration properties of TiO2 nanoparticles during the pool boiling of nanorefrigerants
    Industrial & Engineering Chemistry Research, 2013
    Co-Authors: I. M. Mahbubul, A. Kamyar, Rahman Saidur, Muhammad Afifi Amalina

    Abstract:

    Nanofluid is a promising fluid due to its enhanced heat transfer properties. Nanorefrigerant is a kind of nanofluid that uses a refrigerant as the base fluid. It can enhance the energy and cooling performance of refrigeration and air-conditioning systems. The objective of this paper is to study the migration properties of nanoparticles during the pool boiling of the nanorefrigerant. The effects of different parameters including heat flux, liquid level height, vessel size, Insulation, and lubricating oil on the migration of nanosized particles have been investigated. TiO2 particles with average diameters of 40 nm were used with R141b refrigerant. The experimental results show that the migrated mass of nanoparticles increases with augmenting the initial mass of nanoparticles as well as the applied heat flux. Besides, particle departure from the liquid to vapor augments by increasing the lubricating oil concentration and Adding Insulation to the container. However, the migration of nanoparticles decreases wi…

Therefore, migration properties of nanoparticles during the pool boiling of nanorefrigerants have a distinct relationship with the distribution of nanosized particles. © 2013 American Chemical Society.

  • experience from using prefabricated elements for Adding Insulation and upgrading of external facades
    , 2016
    Co-Authors: Kristina Mjornell

    Abstract:

    At present, there are a number of rational prefabricated systems on the market for Adding Insulation and upgrading exterior walls and facades. A number of such systems were tested and evaluated by Swedish housing companies. This process showed that none of the solutions are fully developed and that, during the projects that were studied, much of the development work took place during the renovation project. The weak points of the systems were generally found to be the connections between the elements and the existing facade, and details such as windows. In several cases, the housing companies had problems with a lack of clarity regarding responsibilities, between those who were to deliver the system and those who were to install it, as well as the division of responsibility for connection and details, such as between a window and the existing building. It is crucial that such issues are solved before a system is designed, produced, and installed. There were also problems with inaccuracies in the measurements of the existing building, which meant that both internal and external adjustments of the prefabricated elements needed to be done at the site. The main barriers to wider adoption of the prefabricated facade systems are that few companies are willing to take total responsibility for the systems and that the systems in their current form are still more expensive than traditional additional Insulation and a new facade layer. Actions to be taken in order to overcome these barriers are the further development of products and systems, as well as the change to prefabrication and an assembly on-site system. The systems must become more economically competitive, and the volume of ordered and produced facade elements must increase. Calculation models should be developed that can be used as funding frameworks to demonstrate the advantages of using such prefabricated systems.
