THERMAL STORAGE AIR-CONDITIONER

摘要

A thermal storage air conditioner is provided to uniformly form temperature distribution inside of a heat storage tank by having an ice making coil capable of rotation. A thermal storage air conditioner includes an outdoor unit(100), a functional unit(200), and a thermal unit(300). The outdoor unit has a compressor(110) and an outdoor heat exchanger(120). The compressor compresses refrigerant to changes the temperature and the pressure of the refrigerant. The refrigerant flows inside of the outdoor heat exchanger and the refrigerant and air are heat-exchanged in the outdoor heat exchanger. The functional unit is installed on one side of the outdoor unit to control the flow of the refrigerant according to operation conditions. A sub oil passage(210) is formed in the functional unit to guide the refrigerant. The sub oil passage has a sub heat exchanger(212) to exchange heat and a sub pump(214) installed on one side of the sub heat exchanger to compulsively control the flow of the refrigerant. The thermal unit is connected to the functional unit. The flow of the refrigerant between the thermal unit and the functional unit is controlled by a second valve(218) and a fourth valve(226).
