The sidewall portion and the ceiling portion are materials through which direct sunlight is transmitted, and at least one of the sidewall portion and the ceiling portion may be provided with a plurality of work doors that can be opened and closed along a length direction.

In addition, in one embodiment, an artificial light source may be provided in the inner space of the case.

In at least one embodiment, in the inner space of the case, a first supply passage is formed at an upper portion to supply cold air supplied from a temperature controller, and a second supply passage is formed at a lower portion to supply hot air supplied from the temperature controller.

The temperature controller supplies cold or hot air to the internal space to control the temperature.

The air circulation fan circulates air in the interior space.

The sensor senses the temperature of the internal space so that the temperature of the internal space is controlled through a temperature controller.

The control unit measures the temperature of the internal space through a sensor and operates an air circulation fan and a temperature controller to maintain the temperature of the internal space at a set temperature.

The energy-saving cultivation chamber may additionally include a carbon dioxide supply unit and a control unit. The carbon dioxide supply unit is controlled by the control unit and supplies carbon dioxide to the inner space of the case.
