Title:
ABSORBING TYPE AIR CONDITIONER
Document Type and Number:
Japanese Patent JP3241623
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an absorbing type air conditioner in which a cooling operation can be continued without producing freezing of refrigerant even if a cooling operation is carried out under a state in which a surrounding atmosphere temperature or a cooling water temperature is not high.
SOLUTION: A controller 9 performs a first diluting operation in which a gas burner 311 is extinguished when (refrigerant temperature (HGE)≤0°C) is detected during a cooling operation in a continuous manner for 20 seconds and an operation of a tandem pump 80 is continued, performs a second diluting operation in which a cooling or heating operation changing-over valve 36 is opened when (HGE≤125°C) is attained so as to circulate absorption liquid and in turn when a relation of HGE≤110°C is attained, the cooling or heating changing-over valve 36 is closed to perform a re-starting of cooling operation.
