Abstract: PURPOSE: To obtain a nitrocellulose composition for urethane, which is inert to isocyanates, by dissolving a nitrocellulose product wetted with water or an alcohol in an organic solvent which is inert to isocyanates, and distilling the solution.  
     CONSTITUTION: A nitrocellulose product wetted with water on an alcohol is dissolved in an organic solvent which is inert to isocyanates. A distillation promoting agent may be added to the resulting solution. This solution is subjected to distillation thereby to distill off the wetting agent together with a portion of the organic solvent, and obtain a dope-like nitrocellulose solution containing the nitrocellulose and the organic solvent inert to isocyanates. Example of the organic solvent include an ester such as ethyl acetate, a ketone such as acetone, and a nitroparaffin.

When the starting of the compressor is detected, the heating operation is secured by the microcomputer 11 for a predetermined period of time T2 to prevent the entry into defrosting operation during the transitional period of the starting of the compressor. After the period of time T2 has elapsed, a pipeline temperature detecting element 6 reads in a pipeline temperature (t) and a comparator 14 decides whether the pipeline temperature (t) is lower than a set pipeline temperature (t1) or (t2). In the case the temperature is higher than the set temperature (t1) or (t2), the comparator 18 decides whether the value of an electric source current I is lower than the set value of electric current (I1 or I2) and defrosting operation is started. Here, in the case the amount of indoor side airflow is large, the defrosting operation is effected using the values (t1), I1 while the same is effected by the values (t2), I2 in case it is smaller.
