Portable refrigerator design

This project designs a portable refrigerator, which can keep the temperature constant at the set temperature range. A portable refrigerator uses temperature sensors, refrigeration equipment, and electronic temperature control and temperature control system. Under the normal operating conditions, it can control the temperature within a certain range. Its basic principle is to collect the refrigerator temperature by temperature probe, and then compare it with the temperature set by the user. When the collected temperature is higher than the set temperature, the thermostat starts the refrigeration system to work. When the collected temperature is less than or equal to the set temperature, the thermostat allows the refrigeration system to power down, the cooling system is stopped, so cycle operation, the temperature inside the refrigerator will remain essentially constant.
