The heat exchange medium in the system of the heat exchange device enters the sprayer for spraying under the driving of the water pump. The controller controls the air conditioner host to be turned off at the same time after receiving the signal, so that the water sprayed by the sprayer is cold water. The sprayer can be installed at positions where components can be installed in the heat exchange device, such as the radiation plate 1 or the frame 90 and other positions.

[0072] The application further provides a heat exchange method for the heat exchange device, comprising: arranging a radiation plate 1, installing the radiation plate 1 below an indoor roof 92, and arranging a spacing between the radiation plate 1 and the indoor roof 92 to define a ventilation channel; arranging at least two water guide grooves 2, arranging the at least two water guide grooves 2 below the radiation plate 1 in sequence, and making the at least two water guide grooves 2 adjustable to expand or retract; arranging a water collecting groove 3 below the water guide grooves 2 to collect condensed water collected on the water guide grooves 2; when cooling, expanding the at least two water guide grooves 2, defining a water guide channel 28 receiving the condensed water in a transverse direction, and arranging the two water guide grooves 2 in a vertical direction in staggered arrangement to define a cold air channel 20; when heating, vertically retracting or sliding the at least two water guide grooves 2 to one side to define a vertical heat radiation channel 21 for the radiation plate 1 to radiate heat exchange.
