Cooling device

A vaccine cooling device comprising:

• at least one closable cooling space;
• an electrically operated cooling circuit configured to cool the at least one closable cooling space;
• and
• a power distributor;
• and the cooling device for providing battery-free buffering of peak loads;
• the power distributor comprising:
• at least one power input;
• a first power output;
• and at least one second power output;
• the at least one power input being configured for connecting the power distributor to at least one solar collector, said solar collector providing a regenerative power source;
• said first power output being a cooling device connection configured for connecting said power distributor to said electrically operated cooling circuit;
• said at least one second power output being an electricity consuming device connection configured for connecting said power distributor to at least one further electricity consuming device;
• said power distributor having a plurality of power output modes with selection between said power output modes being controlled by priority logic of a control system;
• one of said power output modes being a mode in which said power distributor provides power from said solar collector simultaneously to said cooling circuit and to said further electricity consuming device;
• another of said power output modes being a mode in which said power distributor provides power from said solar collector to said cooling circuit without providing power from said solar collector to said further electricity consuming device;
• said priority logic being configured such that, in the event of a lack of electrical power from said solar collector for providing power from said solar collector to said cooling circuit and to said further electricity consuming device, said priority logic preferentially supplies electrical power from said solar collector to said cooling circuit;
• and
• said priority logic being configured to disconnect said further electricity consuming device from said solar collector when the electrical power produced by said solar collector falls below the power consumption of said cooling device and said further electricity consuming device.
