In the embodiment, the heat pipe energy transfer compensator 2 is arranged, and the heat pipe energy transfer compensator firstly precools air and recovers enthalpy difference delta i 2 ＝i A -i D (ii) a Also after cooling and dehumidification, the air is required to be reheated to the point C when being treated to the point D. From D to C, the heat transferred by the heat pipe is utilized, no extra energy consumption is caused, and the energy of reheating air is saved, namely delta i 3 ＝i C -i B (ii) a According to conservation of energy, then Δ i 1 ＝△i 2 ＝△i 3 . Namely, after the heat pipe energy transfer compensator 2 is arranged, twice reheating energy consumption is saved, namely 2 delta i 1 And the energy is saved remarkably.
