Abstract

This project is based on one of the Hydronic Radiant Cooling (HRC) type systems that are Chilled Floor System. This project basically based on the limitation occurring of using the conventional air conditioning such as high utility bills and damage environment. Therefore, by applying Hydronic Radiant Cooling System, the limitation that occurs from conventional air conditional can be dealt. Overall of this project are focusing on measuring the room temperature and humidity inside the environmental chamber. The varied number of copper tube is installed to extend the height of cooling inside the environmental chamber. In additional, by closed the entire ventilation hole on the environmental chamber has been done to keep the heat inside, and small fan been installed at the floor of the chamber to extend the cooling height. The copper tube for chilled floor panel is covered with aluminium sheet during this experiment to increase cooling capacity and silica gel is placed at the air supply entrance to absorb the air moisture from outside before entering the chamber. Chilled water from mini chiller are pumped and circulated inside chilled floor panel through copper tubes. The temperatures in the mini chiller are considered by mixing of water, ice, sodium chloride (salt) and propylene glycol (C3H8O2) with different ratio. The main purpose of this project is to consider of using Chilled Floor as cooling alternative in Malaysia for thermal comfort and to preserve food product. Lastly, by the end of this experiment, the minimum temperature achieved by water chilled inside the mini chiller is -18°C, while 14°C for the temperature inside the environmental chamber.
