[0028] When the outside air temperature is high, the electromagnetic valves 11 in the upper air inlet pipe 3 and the lower air outlet pipe 6 are closed, the electromagnetic valves 11 in the upper air outlet pipe 4 and the lower air inlet pipe 5 are opened, and the exhaust fan 10 in the upper air outlet pipe 4 and the air inlet fan 9 in the lower air inlet pipe 5 are opened. The gas with a higher temperature in the workshop (the temperature of the gas is still lower than the outside temperature) flows through the box 1, the bidirectional plate heat exchanger 2 and the lower outer pipe 8, and then is discharged from the workshop through the upper air outlet pipe 4. At the same time, the outside air flows through the upper outer pipe 7, the bidirectional plate heat exchanger 2 and the box 1, and then enters the bottom space in the workshop through the lower air inlet pipe 5, mixes with the gas with a lower temperature in the workshop, and at the same time, the gas discharged from the workshop and the gas entering the workshop are heat exchanged in the bidirectional plate heat exchanger 2, so that the air entering the inside of the workshop is pre-cooled.

At the same time, the outside air flows through the lower outer pipe 8, the bidirectional plate heat exchanger 2 and the box 1, and then enters the top space in the workshop through the upper air inlet pipe 3, mixes with the gas with a higher temperature in the workshop, and at the same time, the gas discharged from the workshop and the gas entering the workshop are heat exchanged in the bidirectional plate heat exchanger 2, so that the air entering the inside of the workshop is pre-heated.

[0030] With reference to Figure 2 and Figure 3 The ends of the upper outer pipe 7 and the lower outer pipe 8 away from the box 1 are threadedly connected with outer filter screens 14, which can prevent the outside dust from entering the upper outer pipe 7 and the lower outer pipe 8 and further entering the heat exchange channels of the bidirectional plate heat exchanger 2 when the air inlet fan 9 is opened, so as to affect the heat exchange effect of the device.

[0033] When the air temperature outside the workshop is high and the air inlet fan 9 in the lower air inlet pipe 5 is started, the low-temperature liquid is pumped into the lower wave heat exchange pipe bundle 122, so that the air is preliminarily heat exchanged by the bidirectional plate heat exchanger 2 and flows to the lower air inlet pipe 5 and is heat exchanged with the low-temperature liquid by the lower wave heat exchange pipe bundle 122, thereby further reducing the air temperature flowing into the workshop;

[0034] When the air temperature outside the workshop is low and the air inlet fan 9 in the upper air inlet pipe 3 is started, the high-temperature liquid is pumped into the upper wave heat exchange pipe bundle 121, so that the air is preliminarily heat exchanged by the bidirectional plate heat exchanger 2 and flows to the upper air inlet pipe 3 and is heat exchanged with the high-temperature liquid by the upper wave heat exchange pipe bundle 121, thereby further increasing the air temperature flowing into the workshop;

[0035] The humidifying assembly 13 is arranged on one side of the outer side wall of the box body 1 near the upper air inlet pipe 3, and the humidifying assembly 13 comprises a water tank 131 fixedly connected to one side of the outer side wall of the box body 1, an upper atomizer 132 arranged on the inner side wall of the box body 1 near the upper air inlet pipe 3 and connected to the water tank 131 in communication and a lower atomizer 133 arranged on the inner side wall of the box body 1 near the lower air inlet pipe 5 and connected to the water tank 131 in communication;

[0036] When the air inlet fan 9 in the lower air inlet pipe 5 is started, the lower atomizer 133 is started, the water in the water tank 131 is atomized and discharged into the box body 1, and the atomized water enters the workshop along with the air flow entering the workshop through the lower air inlet pipe 5, thereby increasing the humidity in the workshop, when the air inlet fan 9 in the upper air inlet pipe 3 is started, the upper atomizer 132 is started and the water in the water tank 131 is atomized and discharged into the box body 1, and the atomized water enters the workshop along with the air flow entering the workshop through the upper air inlet pipe 3.

[0039] When the outside air temperature is high, the electromagnetic valves 11 in the upper air inlet pipe 3 and the lower air outlet pipe 6 are closed, the electromagnetic valves 11 in the upper air outlet pipe 4 and the lower air inlet pipe 5 are opened, and the air exhaust fan 10 in the upper air outlet pipe 4 and the air inlet fan 9 in the lower air inlet pipe 5 are opened. The air in the workshop with a high temperature at the top is discharged from the workshop through the upper air outlet pipe 4, the box 1, the bidirectional plate heat exchanger 2 and the lower outer pipe 8, while the outside air enters the bottom space of the workshop through the lower air inlet pipe 5 after flowing through the upper outer pipe 7, the bidirectional plate heat exchanger 2 and the box 1, and is mixed with the air in the workshop with a low temperature. At the same time, the air discharged from and entering the workshop is heat-exchanged in the bidirectional plate heat exchanger 2 to pre-cool the air entering the inside of the workshop.

[0040] At the same time, the low-temperature liquid is pumped into the downward wave heat exchange pipe bundle 122, so that the air is preliminarily heat-exchanged by the bidirectional plate heat exchanger 2 and is heat-exchanged with the low-temperature liquid by the downward wave heat exchange pipe bundle 122 when flowing to the lower air inlet pipe 5, thereby further reducing the temperature of the air flowing into the workshop.

[0041] When the outside air temperature is low, the electromagnetic valves 11 in the upper air inlet pipe 3 and the lower air outlet pipe 6 are opened, the electromagnetic valves 11 in the upper air outlet pipe 4 and the lower air inlet pipe 5 are closed, and the air exhaust fan 10 in the lower air outlet pipe 6 and the air inlet fan 9 in the upper air inlet pipe 3 are opened. The air in the workshop with a low temperature at the bottom is discharged from the workshop through the lower air outlet pipe 6, the box 1, the bidirectional plate heat exchanger 2 and the upper outer pipe 7, while the outside air enters the top space of the workshop through the upper air inlet pipe 3 after flowing through the lower outer pipe 8, the bidirectional plate heat exchanger 2 and the box 1, and is mixed with the air in the workshop with a high temperature. At the same time, the air discharged from and entering the workshop is heat-exchanged in the bidirectional plate heat exchanger 2 to pre-heat the air entering the inside of the workshop.

[0042] At the same time, the high-temperature liquid is pumped into the upward wave heat exchange pipe bundle 121, so that the air is preliminarily heat-exchanged by the bidirectional plate heat exchanger 2 and is heat-exchanged with the high-temperature liquid by the upward wave heat exchange pipe bundle 121 when flowing to the upper air inlet pipe 3, thereby further increasing the temperature of the air flowing into the workshop.

[0043] When the air inlet fan 9 in the lower air inlet pipe 5 is opened, the lower atomizer 133 is started, the water in the water tank 131 is atomized and discharged into the box 1, and the atomized water enters the workshop together with the airflow entering the workshop through the lower air inlet pipe 5, thereby increasing the humidity in the workshop. When the air inlet fan 9 in the upper air inlet pipe 3 is opened, the upper atomizer 132 is started and atomizes the water in the water tank 131 and discharges it into the box 1, and the atomized water enters the workshop together with the airflow entering the workshop through the upper air inlet pipe 3.
