Loading space cell and vehicle with a loading space cell

A loading space cell, in particular mobile loading space cell, with a wall structure of a temperature-controllable space and a heating device for heating the temperature-controllable space, wherein at least one floor wall (34) of the wall structure is designed to be heatable at least in regions and wherein the heatable designed part of the wall structure is provided with a heating device (7, 9) which is in heat-transferring operative connection with the inner section (34') of the wall structure facing the temperature-controllable space, is distinguished by the fact that the heating device (7) is formed by an arrangement of channels (80, 81, 82, 83, 84, 85, 86, 87) through which warm air can flow in the interior of the wall structure, wherein the channels form a channel system (8) of air guide channels for the warm air to be introduced into the temperature-controllable space; that at least some of the channels (80, 81, 82, 83) of the channel system (8) have inflow openings (50, 51, 52, 53) at their respective one end, through which the warm air is introduced into the channel system (8); that at least some of the channels (80, 81, 82, 83) of the channel system (8) have outflow openings (54, 55, 56, 57) at their respective other end, through which the warm air can exit into the temperature-controllable space, and that at least some of the channels (80, 81, 82, 83, 84, 85, 86, 87) are at least partially in heat-transferring operative connection with the inner section (34') of the wall structure.
