PROBLEM TO BE SOLVED: To prevent poor desorption while improving the durability of an adsorption type refrigerating machine by a handy means. SOLUTION: With swing doors 202 and 203 closed, a PTC heater 190 is electrically energized. When the temperature of the PTC heater 190 exceeds a specified value (Curie point) Cp and a value of current flowing through the PTC heater 190 is below a specified current value, the desorption is regarded as completed and the energization is stopped. Thus, airtightness is kept to allow preventing of poor desorption while improving durability. |
