B ICE STORAGE UNIT, AN AIR CONDITIONING SYSTEM USING THE SAME AND A CONTROL METHOD D The present invention relates to a super-cooled unit for ice storage, provided with a simple structure with both functions cold storage and hot storage, and an air conditioning system that uses the said ice storage unit and its control method. Said super-cooled ice storage unit comprises an ice storage device (61) and a closed circular tubing that passes through the ice storage device (61) in said closed circular tubing, with an electronic expansion (62) and a first electromagnetic valve (63), a second electromagnetic valve (64) and a third electromagnetic valve (65), wherein said electronic expansion valve (62) is connected in parallel with the third electromagnetic valve ( 65), and the first and second electromagnetic valves (63) and (64) are connected in parallel. Said super-cooled ice storage unit further comprises three external contacts (67), (68) and (69). The super-cooled ice storage unit is connected between a high pressure liquid reservoir (5) and connected in parallel and internal units (7) and (8) Adjusting the working status of different valves in the air conditioning system, the air conditioning system can operate interchangeably in six operating modes.
