AIR-CONDITIONING SYSTEM FOR BUILDING CAPABLE OF CONTROLLING AMOUNT OF HEAT STORAGE

PROBLEM TO BE SOLVED: To provide an air-conditioning system for a building, capable of controlling the amount of heat storage that prevents unneeded energy loss, while maintaining an optimum air-conditioning state and can be automatically operated by quantitatively controlling the building frame heat storage system of the air-conditioning system for the building. SOLUTION: The building air-conditioning system, where a secondary side for circulating a refrigerant is connected to a gravity-type heat pipe for individual dispersion is a building air-conditioning system, capable of controlling the amount of heat storage, that calculates consumption energy in normal operation from the integration value between the opening of an expansion valve and time in cooling, and from the accumulated value of the opening time of a solenoid valve in heating, and obtaining the building frame operation time from the calculated consumption energy for performing the building frame heat storage operation of the building air conditioner.
