OPERATION CONTROL DEVICE FOR AIR CONDITIONER

摘要

PURPOSE:To realize an operation control which is optimum for human sense as well as the economical air conditioning by an arrangement in which the compressor capacity is controlled in accordance with the loading condition that is determined by counting the cumulative operation time period of the compressor in a certain time from the start of operation. CONSTITUTION:The first clock means 1 carries out the time count from the start of operation to its end. The second clock means 2 is activated at the same time as the start of operation. After one hour has passed, the first clock means 1 outputs a stop signal to the second clock means 2 which cumulatively counts the operation time period of a compressor 10, and outputs an operation stop signal after five hours has passed. A temperature comparing means 7 compares the temperature of a room temperature thermistor 6 and the set temperature. A capacity modulating means 3 consists of an operation rate modulating means A that modulates the operation rate of the compressor 10 to 1/3 in proportion to the degree of the cumulative hours of the second clock means 2 and a mode ratio setting means 5 that memorizes three kinds of the switching timing for adjustable operation rate.
