PURPOSE:To provide a thermal accumulation type air conditioner system capable of utilizing a latent heat under both cooling operation and heating operation by a method wherein a thermal accumulation material is composed of a plurality of constituents such as water, polyethylene glycol and the like, the amount of constituents stored in a tank is adjusted to vary ratio of constituents of the thermal accumulation material stored in the thermal accumulation tank. CONSTITUTION:As a thermal accumulation material in a thermal accumulation tank 1, a mixture composed of water and polyethylene glycol is applied. When a cooling operation is to be performed, water in a tank 15 and thermal accumulation material containing a large amount of water are all returned to the thermal accumulation tank 1 under operation of a pump 16. Pump 17 is operated to agitate the thermal accumulation material in the thermal accumulation tank 1 to restrict separation of constituents of the thermal accumulation material. Under this condition, a melting point of the thermal accumulation material becomes 3 deg.C. In case of performing a heating operation, the thermal accumulation material in the thermal accumulation tank 1 is agitated under operation of a pump 17 and at the same time the material is circulated to a separator 12 under operation of pumps 13 and 14. Water in the thermal accumulation material or polyethylene glycol containing a large amount of water is separated through this circulation and stored in the tank 15. At this time, all the water in the thermal accumulation material are removed to enable the melting point to be increased up to 58.5 deg.C. |
