Design of Humidifier Control System for Psychrometric Chamber in the University of Indonesia

Abstract Currently, the Air Conditioner is one of the tools that has become a necessity for people all over the world. Most homes, office buildings to shopping centers use Air Conditioners to increase comfort. Therefore, the use of electricity due to air conditioning is quite large and always increases with the increase in population. This is the government’s concern because the increase in energy required is increasing. The government wants to try to reduce the consumption of electrical energy due to the use of air conditioning without reducing the need for air conditioning for the community. One of the solutions of the Indonesian government, the Ministry of Energy and Mineral Resources, is to apply an energy label for the use of air conditioners by using the Energy Efficiency Ratio (EER) as a parameter to calculate how much EER is in air conditioners. To achieve this, a controlled room called the Psychrometric Chamber is needed where the temperature and humidity of the air can be adjusted as needed. This study aims to complete the humidifier system on the chamber room. The result of this research is the design of a humidifier system as a humidity control system in the Psychrometric Chamber.
