Abstract: A research has been conducted on the design of conditioning chambers with Peltier elements aimed at controlling transfusion blood temperature and analyzing the control system that has been made. The working principle of the control system that is made is the temperature sensor will read the temperature in the chamber, if the temperature reads above 10 °C, the relay will light up and electricity will flow so that the Peltier cooler will work, if the temperature has reached 10 °C, then the relay will off and the electricity will stop to save energy. The relay will turn on again if the temperature rises above 10 °C. The results obtained from this experiment is the Peltier element can cool down for 30 minutes with variations in load 0 mL, 350 mL, 700 mL, 1050 mL, and 1400 mL in the temperature range of 2 °C to 10 °C.
