System and method for CO2 controlled regulation of ventilation, cooling or heating in pavilions, modular buildings and other buildings

摘要

The present invention relates to a system and a method for cooling or heating and ventilation in a building such as a pavilion, which system comprises a combined heat pump and cooling device, which system also comprises ventilation means for generating air flow from an inlet and further through an outlet. A first object of the invention is to achieve a system to control the climate in a small building such as a pavilion by connecting an external climate regulating system to the building. A further object is to limit the installation which has to be performed in the building because most of the technical devices are placed in the outdoor system. The object can be achieved by a system or a method in that the system can be formed in an outdoor module, which outdoor module is connected by at least an outlet air connection from a building and an inlet air connection to the building which system performs measurement of the CO2 by the CO2 sensor in the outlet air connection from the building, which system performs adjustment of the CO2 in the inlet air connection to the building by adding fresh outdoor air to the inlet of the building.
