Abstract
Air Conditioner (AC) merupakan alat yang digunakan untuk mengkondisikan temperature, sirkulasi ,kelembaban dan kebersihan udara di dalam ruangan agar temperature menjadi lebih rendah dibandingkan dengan temperatur lingkungan di sekitar. Pada air conditioner menghasilkan air kondensasi yang biasanya air kondensasi tersebut di buang begitu saja dan tidak dimanfaatkan kembali. Untuk memanfaatkan air kondensasi tersebut maka dibutuhkan sistem pendinginan yang sederhana dengan menggunakan Phase Change Material (PCM) untuk menyimpan energi termal . Phase Change Material (PCM) mampu menyerap dan melepaskan sejumlah besar kalor laten sesuai dengan peningkatan dan penurunan suhu lingkungan.
Beban panas pada workshop harus dihilangkan untuk kenyamanan pekerja atau ABK di workshop. Air kondensasi AHU (Air Hendling Unit) bisa dimanfaatkan untuk menyerap beban panas yang ada di workshop. Salah satu metode yang bisa menjadi opsi untuk menggunakan ulang air kondensasi adalah menggunakan bantuan media pendingin Phase Change Material (PCM).Air kondensasi ini nantinya akan disirkuasikan melewati workshop dengan sistem closeloop
Dari hasil penelitian ini didapatkan debit air yang berasal dari AHU room sebesar atau sebanyak 0,56 liter/menit dengan suhu 10°C, volume reservoir sebanyak 0,168 m3, kebutuhan untuk heat exchanger sebanyak 5,5 L/min dan direncanakan bahwa suhu pada ruangan workshop dapat turun sampai 27°C dibandingkan dengan udara luar sebesar 35°C .maka di dapatkan hasil yaitu Phase Change Material yang digunakan berjenis Ice Gel Propylene Glycol dengan jumlah 135 buah dan bertahan selama 4 jam.

Air Conditioner (AC) is a tool used to condition the temperature, circulation, humidity and air hygiene in the room so that the temperature becomes lower than the ambient temperature. In air conditioner produces condensation water which is usually the condensation water in the flue and not utilized again. To utilize the condensation water, a simple cooling system is needed using the Phase Change Material (PCM) to store the thermal energy. Phase Change Material (PCM) is able to absorb and release large amounts of latent heat according to the increase and decrease of ambient temperature.
The heat expense in the workshop should be eliminated for the convenience of workers or ABK in workshops. Air Hendling Unit (AHU condensation) can be utilized to absorb the heat load in the workshop. One method that could be the option to reuse condensation water is to use the help of the Phase Change Material (PCM) Cooling media. This condensation water will be struck through workshop with Closs Lop system.
From the results of this research obtained the discharge of water derived from AHU room amounting to or as much as 0.56 liters/min with a temperature of 10 ° C, the reservoir volume is 0.168 m3, the need for heat exchanger as much as 5.5 L/min and planned that the temperature in the workshop room can be dropped to 27 °c compared to the outside air by 35 °c. Hence the Phase Change Material used in Ice Gel Propylene Glycol with a total of 135 pieces and lasts for 4 hours.
