    Abstract

    Aplikasi sistem perolehan semula tenaga udara-ke-udara sebagai salah satu teknologi cekap tenaga yang membantu sistem penghawa dingin tradisional dalam bangunan telah mendapat perhatian sejak kebelakangan ini kerana potensinya dalam penjimatan tenaga. Sistem perolehan semula tenaga udara-ke-udara yang direka dalam kajian ini menggunakan jenis plat tetap yang diperbuat daripada membran polimer hidrofilik dan dilengkapi dengan konfigurasi aliran silang untuk membantu penghawa dingin. Matlamat utama kajian ini adalah untuk mengkaji prestasi sistem perolehan semula tenaga udara-ke-udara berdasarkan keadaan cuaca di luar yang telah direka serta data cuaca yang dikumpul berdasarkan persekitaran panas-lembap. Sebuah kemudahan eksperimen telah direka bentuk untuk menghasilkan semula persekitaran panas lembap yang biasa dalam keadaan udara di luar dan dalam bangunan berkait dengan suhu serta kelembapan relatif. Unit ini kemudiannya diuji di bawah syaratsyarat operasi yang seimbang, yang lazimnya digunakan dalam aplikasi. Pada bahagian pertama, pengaruh parameter seperti aliran udara pada (1.0 hingga 3.0 m/s), suhu udara pada (28°C, 31°C, 35°C dan 40°C) serta kelembapan relatif pada (70%, 75%, 80%, 85% dan 90%) telah diuji di bawah keadaan berbeza bagi mengkaji prestasi sistem tersebut. Application of an air-to-air energy recovery system as one of the energy efficient technologies that assists with the traditional HVAC system in building application has gained recent attention because of its potential for energy savings. The air-to-air energy recovery system developed in this study employs a fixed plate type of air-to-air energy recovery system made up of hydrophilic polymeric membrane equipped with cross flow configuration designed to assist air-conditioning. The primary goal of this study is to investigate the air-to-air energy recovery system’s performance based on the outdoor design air-condition and real weather data collected with respect to the hot-humid environment. An experimental facility was designed to reproduce the chosen typical hot-humid environment in outdoor and indoor air conditions with respect to temperature and relative humidity. Next, the system was tested under stable operation conditions as frequently used in practice. For the first part, the operating parameters which are airflow rates of (1.0 to 3.0 m/s), intake air temperature of (28°C, 31°C, 35°C and 40°C) and intake relative humidity of (70%, 75%, 80%, 85% and 90%) were varied under certain air conditions to investigate the system’s performance.
