Problems solved by technology

[0003] In the existing air conditioner, the hot air discharged from the outer circulation unit of the air conditioner is often re-inhaled into the outer circulation unit, causing the back flow of hot air and reducing the heat dissipation efficiency

Embodiment Construction

[0038] Reference figure 1 , Which is a block diagram showing the air conditioner 1 according to the embodiment of the present invention, which includes a condenser 10, a compressor 20, an evaporator 30, an expansion valve 40, a condenser fan 51, and an evaporator fan 52. The compressor 20 acts to pressurize and transfer the high-temperature working fluid W (for example, refrigerant) to the condenser 10. The condenser fan 51 blows the external circulating air flow to the condenser 10 to remove the heat, and the working fluid is cooled into a liquid state, and then passes through After the expansion valve 40 (in another embodiment, the expansion valve can be replaced by a capillary tube), the pressure decreases, the working fluid becomes low temperature and flows into the evaporator 30. The evaporator fan 52 blows the internal circulating air flow to the low temperature evaporator 30, and The effect of cooling the internal circulation air is achieved, and at the same time, the eva...

Abstract

An air conditioning device comprises an external circulation unit. The external circulation unit comprises an external circulation shell, an external circulation air inlet, an external circulation air outlet and a condenser. The external circulation air inlet is formed in the external circulation shell. The external circulation air outlet is formed in the external circulation shell. External circulation airflow enters the external circulation unit from the external circulation air inlet and passes through the condenser, so that heat is removed from the condenser, and the external circulation airflow leaves the external circulation unit from the external circulation air outlet. In a vertical direction, the height of the external circulation air inlet is larger than that of the external circulation air outlet.

Description

Technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner that prevents hot air from returning. Background technique [0002] Existing air-conditioning devices include evaporators (inner circulation), condensers (outer circulation), compressors, and expansion valves. Compressor action transfers high-temperature cold coal to the condenser under pressure, and blows the external circulating air flow to the condenser through the condenser fan to remove the heat. The internal cold coal is cooled and becomes liquid. After passing through the capillary tube or expansion valve, the pressure decreases. The cold coal becomes low temperature and flows into the evaporator. The evaporator fan blows the internal circulation air flow to the evaporator to achieve the effect of cooling the internal circulation air. At the same time, the evaporator absorbs the high temperature so that the cold coal is gasified by the high temperature and then flows bac...
