Condensate is the result of condensation of vapor in the air by the evaporator of the air conditioning (A/C). The production rate of condensate depends on the capacity of the A/C. In addition, the production rate of the condensate is also influenced by the condition of outdoor air. The present study investigates the production rate of condensate produced by A/C in two cities in Indonesia, namely Bandung and Garut. These two cities represent areas with cool and temperate climates. As a result, these two cities have different outdoor air conditions. The investigation was carried out on the split-type A/Cs installed in bedrooms with compressor capacity of 0.5 HP (0.38 kW). Site data collection was carried out for 24 hours, where the amount of condensate, indoor and outdoor air temperatures and relative humidity were recorded for each hour. The results showed that in 24 hours, the A/C in Bandung and Garut produced 18.555 and 20.370 liters of condensate, respectively. A part from that, the condensate rates in Bandung and Garut are equivalent to 773,125 ml/h and 848,750 ml/h, respectively. The correlation between condensate production in Bandung and Garut to the difference outdoor and indoor air temperatures shows a directly proportional relationship. It means that the higher the indoor and outdoor air temperature difference, the higher the condensate generation. [ABSTRACT FROM AUTHOR]
