[0027] The utility model will now be further described in conjunction with the accompanying drawings.

[0028] Embodiment 1

[0029] Combined with Figure 1-4 The box body 1 is provided with a partition 2, and the partition 2 divides the space in the box body 1 into a cavity 1 3 and a cavity 2 4. The cavity 1 3 is provided with a compressor 5, and a condenser 6 is provided on one side of the compressor 5 in the cavity 1 3. The upper end surface of the box body 1 is provided with a condensing fan 7, and the condensing fan 7 corresponds to the position of the cavity 1 3. The condensing fan 7 provides wind force to the condenser 6;

[0030] An indoor blower 8 is provided in the cavity 2 4, an air outlet 9 connected to the cavity 2 4 is provided on the side of the box body 1, the air outlet of the indoor blower 8 corresponds to the position of the air outlet 9, an evaporator 10 is provided above the cavity 2 4, a throttling component 11 is provided in the cavity 2 4, and the compressor 5, condenser 6, evaporator 10, and throttling component 11 are connected through system pipelines;

[0031] Self-locking universal wheels 12 are provided at the four corners of the lower end surface of the box body 1;

[0032] The upper and lower ends of the condenser 6 are respectively connected to the upper end surface and the lower end surface of the box body 1, and the condenser 6 is arranged on one side of the cavity 1.

[0033] When the device is running for cooling, the compressor 5 discharges high-temperature and high-pressure refrigerant into the condenser 6, transfers heat to the air through condensation, and then discharges the heat through the condensing fan 7. The condensed liquid refrigerant enters the throttling component 11, enters the evaporator 10 after throttling, and the refrigerant absorbs the heat of the air through the evaporator 10 to complete evaporation, so that the temperature of the air passing through the evaporator 10 is reduced, and the cold air is sent into the room through the indoor blower 8. After the refrigerant evaporates, it becomes a gaseous refrigerant and enters the compressor 5, completing the refrigeration cycle. When the device is running for heating, the compressor 5 discharges high-temperature and high-pressure refrigerant into the evaporator 10, transfers heat to the air through condensation, and then sends the heat into the room through the indoor blower 8. The condensed liquid refrigerant enters the throttling component 11, enters the condenser 6 after throttling, and the refrigerant absorbs the heat of the air through the condenser 6 to complete evaporation, so that the temperature of the air passing through the condenser 6 is reduced, and the cold air is discharged through the condensing fan 7. After the refrigerant evaporates, it becomes a gaseous refrigerant and enters the compressor 5, completing the heating cycle. The compressor 5 and the indoor air supply 8 both adopt frequency conversion technology, which can achieve efficient operation under partial load conditions and save more energy.

[0034] The air outlet 9 is designed as a circular structure with a flange, which is convenient for connecting a circular air duct. At the same time, four self-locking universal wheels 12 are installed at the bottom of the unit to facilitate the movement of the unit.

[0035] Embodiment 2

[0036] Combined with Figure 1-2 A ventilation grille 13 is provided on the side of the box body 1, and the ventilation grille 13 corresponds to the position of the cavity 24;

[0037] The ventilation grille 13 is connected to the box body 1 by screws;

[0038] The compressor 5 and the indoor blower 8 are connected to the lower end surface of the box body 1 through positioning bolts;

[0039] The self-locking universal wheel 12 is connected to the box body 1 via connecting bolts.

[0040] On the basis of the first embodiment, the ventilation grille 13 ensures the circulation of air in the second cavity 4. The ventilation grille 13, the compressor 5, the indoor blower 8 and the self-locking universal wheel 12 can be freely disassembled and assembled with the box body 1, which is convenient for the replacement and maintenance of the unit components.

[0041] The utility model and its implementation methods are described, and such description is not restrictive. The drawings are only one of the implementation methods of the utility model, and the actual structure is not limited thereto.
