Abstract: <P>PROBLEM TO BE SOLVED: To surely prevent freezing of a liquid circuit W when the liquid is not circulated in a heat exchanger.  <P>SOLUTION: This heat exchanger is provided with a liquid temperature sensor 16 detecting the liquid temperature in the liquid circuit W3, an opening/ closing valve 13 intermittently passing the liquid to the liquid inflow passage W1 to the heat exchanger 3, a suction valve 14, a three-way valve 15 changing over the passage of the liquid to a discharge side in a liquid outflow passage W2 from the heat exchanger 3, and a circulation pump 9. When the liquid temperature detected by a liquid temperature sensor 16 becomes lower than a prescribed temperature with the operation of the circulating pump 9 stopped, the inflow of the liquid from the opening/closing valve 13 is stopped, the three- way valve 15 is changed over to the discharge side, and the circulation pump 9 is operated by prescribed conditions so as to discharge the liquid in the heat exchanger 3. When the liquid temperature in the liquid circuit W is lowered to some temperature of a freezing feasibility with the liquid non-circulated, the liquid in the liquid circuit W is thus discharged (drained) from the three-way valve 15 so as to surely prevent the freezing of the liquid circuit W.  <P>COPYRIGHT: (C)2003,JPO
