An AAATHP is designed to make the non-evaporated liquid refrigerant stemming from the evaporator according to the operational condition of the AAATHP to rectify the refrigerant vapor to be sent to the rectifier from the regenerator, thus improving the efficiency of the rectifier and safely maintaining the operational system of the AAATHP. The AAATHP comprises the following parts: An automatic switch valve to send liquid refrigerant accumulated at the bottom of the evaporator. The heat exchanging pipe enables the liquid refrigerant formed by the evaporator to flow in the rectifier so as to enable the liquid refrigerant sent out by the automatic switch valve to exchange its heat with the refrigerant vapor coming to the rectifier from the regenerator. A first liquid refrigerant passage pipe formed between the automatic switch valve and the heat exchanging pipe sends the liquid refrigerant accumulated at the bottom of the evaporator to the heat exchanging pipe. A second liquid refrigerant passage pipe enables the flow of the liquid refrigerant into the evaporator together with the liquid refrigerant condensed by the condenser.
