Abstract
The invention provides a steam compression-typed integrative machine with dual functions of air conditioning and dehumidifying, and also provides a control method thereof. The steam compression-typed integrative machine with dual functions of air conditioning and dehumidifying comprises a compressor arranged in a shell, evaporators which are not arranged in single row, condensers which are not arranged in single row, and a throttling mechanism. The high-pressure outlet of the compressor is communicated with one end of the front-half part of the evaporator; the other end of the front-half part of the evaporator is communicated with one end of the front-half part of the condenser by a first throttling mechanism; the other end of the front-half part of the condenser is communicated with the low-pressure inlet of the compressor; and the other end of the rear-half part of the evaporator is communicated with one end of the rear-half part of the condenser by a second throttling mechanism. When running normally, the integrative machine is a refrigeration system with dual flowing passages; when a four-way reversing valve changes the direction, one passage of the evaporator refrigerates and the other passage thereof generates heat; and the condenser also has two passages: one passage generates heat and the other passage refrigerates, thus achieving the effect of the dehumidifier when running, thereby realizing that the functions of air conditioning and dehumidifying are carried out simultaneously.
