In order to improve the comfort of a motor home, the motor home can be provided with a parking air conditioner as a refrigerating system in the motor home, the parking air conditioner adopted in the related technology can be divided into two types according to the structure, one type is an integrated parking air conditioner, such as an overhead air conditioner, the other type is a split parking air conditioner, such as a household wall-mounted air conditioner, and the working voltage of the air conditioner is 220V regardless of the overhead air conditioner or the household wall-mounted air conditioner. Because the voltage of the battery that can bear on the car as a house is 48V usually, so the parking air conditioner need have the commercial power to insert, just open the dc-to-ac converter and just can use, wherein, the dc-to-ac converter can cause the electricity transformation loss on the one hand, causes the waste of the energy, and on the other hand easily produces the inefficacy risk in the driving operating mode, so the parking air conditioner can not use in the driving operating mode. In addition, the refrigeration capacity of integral type parking air conditioner is mostly within 2.4KW, and refrigeration effect is not good in the car as a house, and the refrigeration capacity of domestic hanging air conditioner is 3.5KW at most usually, when the car as a house is in the insolate operating mode, also not good to the refrigeration effect of car as a house.
In view of this, the embodiment of the application provides a parking air conditioning system applied to a motor home and a control method, and the parking air conditioning system can effectively refrigerate when the motor home is in a driving working condition and a parking working condition on the basis of energy conservation.
