Title:
AIR CONDITIONER
Document Type and Number:
Japanese Patent JPH01122393
Kind Code:
A
Abstract:
PURPOSE:To make hardly affected by an extraneous noise to transmission lines and to rotate a compressor in a frequency as desired, by encoding a frequency set value to transmit to a control circuit. CONSTITUTION:When a user sets up a room temperature setting means 11 in an indoor machine 2, the capacity of indoor air conditioning load is transmitted to a frequency setting means 14 in an outdoor machine 1 depending on the relations to a room temperature detection means 12. The frequency setting means 14 sets up a predetermined frequency, then this frequency value is encoded in parallel with an encoding frequency transmission means 15 and this encoded frequency is sent out to multiple transmission lines 20. When a waveform generation circuit 16 receives the encoded frequency, a confirmation signal is sent to a control circuit 13 with an encoded frequency confirmation means 17, while the output of a frequency converter 4 is adjusted to control a compressor 5.
