Row mode.
In the present embodiment, the temperature of environment where detection unit 702 obtains mobile air conditioner in cooling mode, it is easy in time
Adjustment is responded with the running status of air-conditioning according to environment temperature T change.Whether judging unit 704 judges environment temperature T
Less than or equal to design temperature Ts, when the judged result of judging unit 704 for when being, i.e. when environment temperature T is less than design temperature Ts,
Now mobile air conditioner has been dropped to environment temperature T below design temperature Ts by refrigeration, and control unit 706 controls frequency conversion compression
Machine frequency reducing is run, and on the one hand slows down the heat exchange of refrigerant, and then reduces the refrigerating efficiency of mobile air conditioner, prevents refrigerating efficiency is higher from making
Environment temperature T continues to reduce, and environment temperature T is maintained around design temperature Ts, is easy to keep environment temperature T stable, improves
The comfort level of user;On the other hand, frequency-changeable compressor frequency reducing operation can reduce energy consumption, mobile air conditioner is become in environment temperature T
Energy consumption can be reduced when being bordering on design temperature Ts, makes mobile air conditioner energy consumption less.Control unit 706 determines environment temperature T simultaneously
Residing temperature range, it will be understood that corresponding to the temperature range residing for different environment temperature T, mobile air conditioner is in difference
Working condition, therefore control unit 706 according to temperature range control mobile air conditioner indoor fan operational mode so that ring
Border temperature T it is higher when can rapid decrease, can change when environment temperature T is relatively low slowly, and leveling off to design temperature Ts
When environment temperature T-phase is made environment temperature T fast approaching design temperature Ts, and can enough prevents environment temperature T to stable
Cause temperature too low because decline is too fast.
What deserves to be explained is frequency-changeable compressor, which can correspond to environment temperature T, carries out continuous frequency regulation, movement is realized
The working condition of air-conditioning can be adjusted corresponding to environment temperature T in real time, can reduce the unnecessary energy consumption of frequency-changeable compressor,
Increase the energy-saving effect of mobile air conditioner.Meanwhile when detecting environment temperature T and adjusting the running status of blower fan according to environment temperature T,
It is simple to operate due to only detecting environment temperature T, it is easy to implement, can not only improves user's by simply detecting and adjusting
