Abstract
The present disclosure relates to the field of air conditioning technology. In particular, it involves a control method and control device based on a DC variable speed AC compressor.
Claims16
A variable speed AC control system comprises:
- speed control calculation unit, database unit, an information acquisition unit, network communication unit and speed control unit, wherein
- the speed control unit is for running variable speed compressor so that output is satisfied while maintaining preset thermostat setting and that next compressor-off time1 coincides with outside peak/lowest temperature timing;
- and
- the information acquisition unit is for collecting thermostat setting and outdoor temperature;
- and
- the database unit is for storing/providing lookup data for indoor temperature and outdoor temperature for a given compressor-off duration time1, which are needed by the speed control calculation unit;
- and
- the network communication unit is used to obtain in advance outdoor temperature values as forecast.
5 more elements
A variable speed AC control method, comprising:
- receiving outdoor temperature curve as forecast;
- based on the temperature curve, compressor-off duration time1 and compressor-on duration time2, determine compressor operation status at the timing of peak/lowest temperature;
- further based on peak temperature timing and operation cycle timing that precedes it, modifying that operation cycle's compressor-on time2 timing as speed control strategy adjustment while maintaining preset thermostat setting so that next compressor-off time1 coincide with the timing of the peak/lowest temperature.
A non-transitory computer-readable medium having stored thereon a set of computer-executable instructions for causing a first device to perform steps comprising:
- receiving outdoor temperature curve as forecast;
- based on the temperature curve, compressor-off duration time1 and compressor-on duration time2, determine compressor operation status at timing of peak/lowest temperature;
- further based on peak temperature timing and operation cycle timing that precedes it, modifying that operation cycle's compressor-on time2 timing as speed control strategy adjustment while maintaining preset thermostat setting so that next compressor-off time1 coincide with the timing of the peak/lowest temperature.
