Overview

Temperature management has a big effect on how well the condensation process works, which in turn has a big effect on the quality and quantity of coconut wine production. A coconut wine company in Tayabas City is experiencing quality issues with its products and a decrease in output because it lacks a dedicated temperature controller for its condenser unit. This capstone project aimed to create a long-term solution: a solar-powered temperature control system for the condenser. In the design process, we looked at the thermal needs of the condensation process and came up with a control system that used temperature sensors driven by the Arduino Uno. A solar photovoltaic (PV) system was made to power the controller, motor, motor control system, Arduino, and battery storage system. This work was done to make sure that the system could run on its own and be good for the environment. The results show that the temperature control system correctly monitors the water temperature of the condenser. The relay goes off about 5 ms after the actual value changes to the set value (55°C > 45°C) and stops when the actual value is less than the set value (29°C < 45°C). The solar photovoltaic system produces enough voltage, with a peak of 14.6 V and an on-site test showing 14.2 V, to show that there is enough sunlight in the area to power the system. The water pump sends 40 liters of water per minute (LPM) to an 8-liter condenser for 5 seconds. This mimics the process of keeping the condensation going that is needed to make lambanog. The worker evaluations got a lot of positive feedback, with a mean score of 4.39. This result shows that people were very happy with how well the system worked and how quickly it worked. The proposed design is expected to greatly improve the consistency and quality of the coconut wine by keeping the condensation temperatures at their best levels and reducing output losses. Also, adding solar PV technology to the temperature control system makes it a long-lasting and cheap way to get energy. This reduces the system’s dependence on the electrical grid and encourages environmentally friendly production methods in the local coconut wine business.
