When the cooling mode is selected, after the mobile air conditioner is turned on, the camera first detects the position of the user, and then moves to a distance of 50cm from the target user; Control and other electric components provide continuous power, compressor 1 compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure refrigerant gas; after that, the high-temperature and high-pressure refrigerant gas enters the evaporator 4 through the four-way reversing valve 2, and passes through the The forced convection heat exchange of the fan turns the high-temperature and high-pressure refrigerant gas into a low-temperature and high-pressure refrigerant liquid; then, the blown heat is sent to the indoor environment through the air outlet 14 of the air conditioner; then, the low-temperature and high-pressure refrigerant liquid passes through the throttling module Then it becomes a low-temperature and low-pressure gas-liquid two-phase refrigerant; finally, the low-temperature and low-pressure gas-liquid two-phase refrigerant enters the condenser 3, becomes a low-temperature and low-pressure refrigerant gas, and blows the cooling capacity to the environment through the air strip directly in front , to cool down the environment around the user. 3. When the heating mode is selected, the temperature of the refrigerant in the evaporator 4 is lowered to condense; while the condenser 3 plays the role of evaporation, and the principle is just opposite to that of the cooling mode.

Compared with the conventional vapor compression refrigeration cycle system, the gas injection enthalpy increase refrigeration cycle system adopted in the present invention, because the gas after the first throttling is separated, it enters the compressor 1 again for compression, and then sends it to the lower In a refrigeration cycle, the energy efficiency of the air conditioning system will be increased; and the introduction of the energy-efficient air jet enthalpy-increasing refrigeration system into the mobile air conditioner not only increases the use range of the mobile air conditioner, but also improves the air conditioner.
