Abstract

This study aims to design a control system with fuzzy logic on a system of cooling the storage of soft drinks with thermoelectric coolers. This storage can be carried in a vehicle using a DC electric power from a photovoltaic solar cell mounted on the roof of the car. Under certain conditions the energy source of cigarette lighter in a car can replace the solar cells. The test results show that a temperature of 15oC can be reached within 30 minutes with fuzzy control, while without fuzzy control the time needed in 63 minutes, 30 minutes longer.

Abstract

The effectiveness of an air conditioner does not only depend on the design of the air-conditioner solely. Several factors affect the effectiveness of the cooling process of a room. One of the main factors in obtaining optimal results in the cooling process of a room is the rate of heat flow that enters a conditioned space. The amount of heat flow that enters a conditioned room affects the final temperature of the room. The ceiling is a part of the room that has a immense heat-flow rate. That is because the air temperature above the plafond is relatively high, and the thickness of the room plafond is relatively compact. It is necessary to analyze the room plafond material thermal resistance in increasing the heat absorbtion efficiency of household air conditioners. The thermal resistance of the material effect on the average room temperature, room temperature map, and the energy consumption is examined experimentally. The result shows that by occupying the plafond with a Styrofoam layer, the average room temperature decreases by 1.3⁰C, the air conditioner cooling capacity decreases by 0.402 kW, electric current decreases by 0.006 A compared to the existing room condition.
