Two things that become world concern are energy crisis and environmental problem, Refrigerator is
one of the causes of the problems either direct or indirect. Refrigerator uses electricity source that comes
front fossil fuel as indirect cause of energy crisis and environmental' problem which contributes to ozone
depletion and global warming by using the refrigerant. Therefore we need a solution that can answer
the problems. The solution is photovoltaic refrigerator .system with hydrocarbon refrigerant. This system
uses photovoltaic module connected to the inverter. The function of inverter is to convert i2 Volt DC
electric voltage from photovoltaic module into 220 Volt A C electric voltage, The refrigerant are
hydrocarbon R-600a and HC-134 which charged at 20 bar pressure. The experiment shows that the
inverter which suitable for refrigerator is pure sine wave inverter type and the alternative refrigerant is
R-600a. Refrigerator with photovoltaic module can be used until 21.5 hours without charging.
