Temperature-controllable container with vacuum insulation elements and with an interior space, which container comprises a wall with an opening for objects to be placed into the interior space, and a door element closing the opening, wherein transport elements are arranged on an outer surface of the container, which transport elements are designed to enable lifting by means of a transport vehicle, and wherein the container further comprises a temperature control unit which is designed so as to bring the interior space to a predetermined temperature T, wherein the temperature control unit comprises a heating/cooling unit operated via a solar energy device or a heating/cooling unit operated via a power supply network, and wherein a receptacle means for melt-storage elements or sample bodies is arranged in the interior space, which receptacle means is designed so as to position at least two melt-storage elements or sample bodies at a distance from each other.

A refrigeration device has a condenser coil that has periodic access to outside air. A time-activated thermostat controls the operation of an evaporator coil that is in thermal contact with a reservoir containing phase change material. A thermally conductive pipe containing antifreeze fluid is connected to a pump that circulates the antifreeze fluid inside the pipe. A first portion of the pipe is inside the reservoir in thermal contact with the phase change material and a second portion of the pipe is near an air fan or connected to a fan coil unit to exchange heat through the pipe between the reservoir and the air blown by the fan or the fan coil unit. The evaporator coil produces a phase change in the phase-changing material in the reservoir at night when outdoor temperature is colder than during day and the phase-change material is used during day to cool air blown by the air fan or the fan coil unit. The air fan and a portion of the pipe can be outside of the refrigeration device and be detached.
