A method of maintaining a space in a means of transport, such as a vehicle, at a desired temperature. The vehicle is provided with a storage tank containing a medium having a suitable temperature. According to the invention the storage tank is part of the transport means, the storage tank possesses an inlet opening for increasing the capacity for maintaining the space at the desired temperature, and is thus achieved; i) by feeding through the inlet opening a regenerating medium-comprising liquid and, after heat exchange between the regenerating medium and the medium, discharging the regenerating medium-comprising liquid; or ii) by via the inlet opening replacing the medium in the storage tank comprising liquid with medium-comprising liquid having a greater capacity of maintaining the space at the desired temperature.

What is claimed is: 1. A method of maintaining a space in a means of transport at a desired temperature, which means of transport is in an environment whose ambient temperature is different from the desired temperature and possesses a storage tank containing a medium having a third temperature, the method comprising the steps of: selecting the third temperature such that the desired temperature lies between the third temperature and the ambient temperature; during transport allowing heat exchange to take place between the storage tank and the space to maintain the space of the transport means at the desired temperature during transport causing a medium in the storage tank to have a reduced capacity for maintaining the space at the desired temperature; and when the means of transport stands still, increasing the capacity for maintaining the space at the desired temperature with the aid of a device that does not form part of the means of transport; wherein the medium in the storage tank comprises solid elements with which the storage tank is filled, the solid elements having capacity to maintain the space at the desired temperature, and wherein the storage tank possesses an inlet opening for increasing the capacity of maintaining the space at the desired temperature, and wherein this is achieved by feeding through the inlet opening a regenerating medium-comprising liquid to surround the solid elements and, after heat exchange between regenerating medium and the solid elements, discharging regenerating medium-comprising liquid. 2. A method according to claim 1, wherein as the medium a phase change material is used. 3. A method according to claim 1, wherein at least 50% of the regenerating liquid medium surrounding the solid elements is removed from the storage tank and the remaining medium is used for maintaining the space at the desired temperature. 4. A method according to claim 3, wherein the remaining liquid medium is used as medium for maintaining the space at the desired temperature by circulating it in a heat exchanging relationship with that space, wherein the medium after exchanging heat with the space is introduced into the storage tank at the top and allowed to flow downward along the solid elements. 5. A method according to claim 3, wherein a further medium is used as medium by circulating it in the space in a heat-exchanging relationship with that space, with the remaining liquid medium being pumped from the bottom of the storage tank upward in order to be brought in contact with the solid elements in the top of the storage tank, and the further medium after heat exchange with the space at the bottom of the storage tank is brought into a heat-exchanging relationship with the liquid medium that flowed downward over the solid elements. 6. A method according to claim 1, wherein between the device for increasing the capacity of maintaining the space at a desired temperature and the transport means a buffer vat is provided. 7. A method according to claim 1, wherein the transport means is an electric vehicle and the space being heated is the space for the passengers. 8. A method according to claim 1, wherein the space is a space to be cooled, the transport means possesses a storage tank containing a medium with a low temperature, cold is withdrawn from the medium in order to maintain the space of the transport means at a desired temperature during transport which results in a medium having a reduced cooling capacity, and during standstill of the transport means the cooling capacity is increased with the aid of a cooling device, which is not part of the transport means, the storage tank is part of the transport means, the storage tank possesses an inlet opening for increasing the cooling capacity, and the cooling capacity is increased by i) feeding a cooling medium through the inlet opening and discharging heated cooling medium, with the cooling medium having a lower temperature than the medium in the storage tank; or ii) the medium in the storage tank is replaced via the inlet opening with medium having a greater cooling capacity. 9. A method according to claim 8, wherein the medium is a slurry comprised of ice and an agent lowering the freezing point. 10. A method according to claim 1, wherein the inlet opening is provided outside the space and the capacity of maintaining the space at the desired temperature is improved without opening the space.
