Reduce or minimize the surge and mechanical stress of the energy during compressor 12 starts.
Control module 22 can receive the ambient outdoor air temperature (input 130) measured by sensor 24, and be
System 10 determines whether ambient outdoor air temperature is higher than the first predetermined temperature value (for example, such as 90 Fahrenheits when being in refrigerating mode
Degree).If ambient outdoor air temperature is less than the first predetermined temperature value, control module 22 can continue in low capacity pattern
Compressor is operated under (state 120), until meeting cooling requirement (that is, the temperature in the space to be cooled is down to such as thermostat
Under selected set point temperatures indicated by 26, and desired signal Y is switched to " closing " by thermostat), until from connecing
The total run time T of compressor 12 is more than predetermined low capacity running time T 1 or until compressor from when receiving desired signal Y
12 or system 10 be manually turned off or diagnose or protection algorism covering algorithm 100 until.For example, predetermined low capacity run time
