As shown in figure 11, control system 1100 according to an embodiment of the invention, for mobile air conditioner, including：Thermometric list Member 1102, for obtaining the environment temperature of mobile air conditioner local environment；Execution unit 1104, for being less than or waiting in environment temperature When preset temperature, the frequency reducing operation of control frequency-changeable compressor.
Under refrigeration mode, obtain mobile air conditioner local environment environment temperature, for mobile air conditioner power adjust provide according to According to preset temperature is the design temperature that user inputs to mobile air conditioner, and after mobile air conditioner runs certain time, environment temperature is small When preset temperature, indoor temperature reaches the refrigeration requirement of user, and frequency-changeable compressor and indoor fan are mobile air conditioner Important power component, frequency-changeable compressor frequency reducing operation is now controlled, and control the indoor fan fall-back of mobile air conditioner, entered One step reduces the unnecessary energy consumption of air-conditioning, and then reduces the energy consumption of mobile air conditioner whole service process, promotes energy-conserving and environment-protective.This Outside, it is simple to operate due to only detecting environment temperature, it is easy to implement.
Further, control system 1100 also includes：Indoor fan control unit 1105, for being less than in environment temperature or During equal to preset temperature, indoor fan stopping or the fall-back of mobile air conditioner are controlled.
When environment temperature is less than or equal to preset temperature, now environment temperature is relatively low, therefore controls the room of mobile air conditioner Inner blower stops or fall-back, reduces and is being not required to caused unnecessary energy consumption of significantly freezing, and then reduces shifting The energy consumption of dynamic air-conditioning whole service process, promotes energy-conserving and environment-protective.
Further, control system 1100 also includes：Outdoor fan control unit 1106, for being less than in environment temperature or During equal to preset temperature, outdoor fan stopping or the fall-back of mobile air conditioner are controlled.
When environment temperature is less than or equal to preset temperature, now environment temperature is relatively low, therefore controls the room of mobile air conditioner Outer blower fan stops or fall-back, on the one hand reduces the heat exchange of mobile air conditioner and outdoor environment, and then reduce the system of mobile air conditioner Cold efficiency, the heat exchange of room air and mobile air conditioner is reduced, makes variation of ambient temperature gentle, reduces because variation of ambient temperature is too fast Cause the possibility that environment temperature is too low, be easy to so that environment temperature is maintained in a stable scope；On the other hand reduce Power consumption of the mobile air conditioner when environment temperature is less than or equal to preset temperature, makes mobile air conditioner more save.
