<p>The invention has its object to provide an absorption water chiller/heater provided with a high quality fuel system and an exhaust heat utilization system and capable of effectively preventing crystallization in a heat exchanger mounted on a piping of the exhaust heat utilization system and having exhaust heat introduced from outside thereinto and preventing temperature rise at a high temperature regenerator and corrosion attendant thereupon, and a method of controlling the same. In the absorption water chiller/heater and the controlling method of the same, according to the invention, when shutdown detecting means detects generation of a shutdown signal of a solution pump or a combustion burner, clock means judges whether or not a predetermined period of time has lapsed after the shutdown of the solution pump or the combustion burner, and if predetermined period of time has lapsed, control means outputs a control signal to a branch means to permit a fluid containing exhaust heat to bypass the heat exchanger. In addition, the absorption water chiller/heater of the invention detects an opening and closing condition of a three-way valve to judge whether the water chiller/heater is in an exhaust heat introduction operating mode or a normal operating mode, thus automatically regulating opening upper limiters of a high quality fuel regulating throttle valve and a combustion air regulating throttle valve of a high quality fuel combustion burner provided in the high temperature regenerator for the respective modes. <IMAGE></p> |
