Overheating is a common phenomenon in a tropical country like Bangladesh. So, ensuring the thermal comfort of hospital patients is necessary for proper health treatment. But in Bangladesh, the thermal comfort of the patient is compromised as installation of the air conditioning system in every general ward of the hospital is impossible due to economic constraints. So, a cheap but effective solution is badly needed to cope with this situation. In that case, PCM (phase change materials) can be an alternative to improve the thermal condition and reduce temperature fluctuation in hospitals in Bangladesh. Phase changing ability at a constant temperature and latent heat storage property of PCM have been proved very effective for the improvement of building thermal condition over the years. In this study, the improvement of thermal condition of the general ward of Patuakhali Medical College (PkMC) is analyzed using PCM as a retrofitting option. A numerical simulation work is performed to analyze and compare the effect of three different PCMs on the enhancement of thermal comfort hours. Finally, based on the result, the best PCM is chosen for optimum thermal management. |
