| 摘要 |
The invention is directed to an air conditioning unit having a refrigerating fluid loop comprising a compressor, a condenser, a liquid/gas separating reservoir, an expansion device, an evaporator and a pre-expansion device, inserted between the condenser and the reservoir, which is capable of producing a pressure drop ranging between 1.5 and 14 bars to reduce the fluid pressure down to its vapor saturating pressure. The reservoir can also contain a variable amount of liquid to compensate the fluid losses in the loop by maintaining the sub-cooling temperature constant in the condenser and consequently the heating capacity capable of being absorbed by the evaporator. |
