いた。2. Problems with the structure of the conventional example A two-chamber air conditioner that uses pole number conversion to control the capacity of a compressor is well known, and will be described below. Figure 1 is an upper air circuit diagram, where 1 is the operation switch for the first chamber, 2 is the 51P switch for the second chamber, and a microcomputer (hereinafter referred to as microcomputer) 3 controls the ON state of switch 1.2. If either the first chamber or the second chamber is in operation, relay 4 is turned on, and compressor 5 driving relay 6 is turned on. Well, the microcomputer 3 determines whether to operate only the - room or to operate two rooms at the same time, turns on relay 7 if it is two room operation, and energizes relay 9 which energizes pole number conversion coil 8. Reduce the number of poles and increase the running force of the compressor 5. In this method, the input to the microcomputer 3 is the operation switch 1.
and 2, the capacity can only be controlled in two stages, and comfort is impaired in air conditioners for multi-room operation. Even if a frequency conversion method is used to vary the capacity of the compressor e., since the input is in two stages, it has the disadvantage that the advantage of the frequency change method, which is the wide range of capacity variation, cannot be fully utilized.
