The utility model discloses a
variable frequency control's
air conditioning system, including compressor;Variable frequency module is used for adjusting the operation frequency of compressor;Controller is electrically connected with variable frequency module, indoor temperature sensor,
outdoor temperature sensor, human detection module and timing module respectively;After the controller starts, through variable frequency module control compressor work until the indoor temperature that indoor temperature sensor detects reaches the set temperature. The utility model provides
variable frequency control's
air conditioning system, and the human detection module identifies the nobody state and triggers the timing
delay shutdown, avoids the compressor to run continuously when long -term off -site, reduces the invalid
energy consumption, maintains the compressor operation in the preset
waiting time, ensures the indoor temperature constant when the user returns after short -time leaving, eliminates temperature fluctuation, utilizes the timing module buffer mechanism and reduces the compressor frequent start -stop number (especially short -time off -site scene), reduces the start -stop current
impact, prolongs the compressor life.
