[0002] The ambient temperature and humidity in an industrial air compressor room directly affect the efficiency of the air compressor, with ambient temperature having a significant impact on the compressor's exhaust temperature. The optimal exhaust temperature range for an air compressor is typically 75℃-95℃.

[0032] In one embodiment of the present invention, the waste heat from the oil of the air compressor 1 is recovered by the oil waste heat recovery unit. While cooling the oil, hot water can be produced, which can be used as a heat source for terminal heating or bathing. The exhaust waste heat recovery unit performs local exhaust ventilation for the air compressor 1, exhausting the high-temperature air around the air compressor 1. In autumn and winter, the hot air is directly sent to the industrial workshop / factory to realize the heating of the industrial plant and recover the waste heat of the ambient air of the air compressor. In summer, the cooling module is used to organize the air supply in the machine room, regulate and control the temperature field in the machine room, ensure the efficiency of the air compressor 1, realize efficient convection heat dissipation, and improve heat exchange efficiency.

[0033] As an optional implementation, the oil waste heat recovery unit includes an oil waste heat recovery unit 17, which is equipped with an oil pipeline 13. Both ends of the oil pipeline 13 are connected to an air compressor 1. A water tank 12 is installed at the bottom of the oil waste heat recovery unit 17, which is located directly below the oil pipeline 13. A first spray pipe 14 is installed at the top of the oil waste heat recovery unit 17. The water sprayed by the first spray pipe 14 absorbs the heat of the oil pipeline 13 and falls into the water tank 12.

[0034] In one embodiment of the present invention, the waste heat of the oil in the air compressor 1 is recovered throughout the year. While cooling the oil, hot water can be produced, which can be used as a terminal heat source or a heat source for bathing. This realizes the recovery of waste heat from the oil in the air compressor 1, reduces the system's operating power consumption, and enables energy-saving operation.

[0035] As an optional implementation, a hot water supply pipe 15 is connected to the water tank 12, and the output end of the hot water supply pipe 15 is connected to the external heating equipment.

[0038] In one embodiment of the present invention, the waste heat of the air compressor 1 is collected by the exhaust hood 2 and the exhaust pipe 10.

[0039] As an optional implementation, the top of the main pipe is connected to an industrial plant heating pipe 21, the top of the auxiliary pipe is provided with an exhaust port 18, a second exhaust fan 19 is installed in the main pipe, and a first exhaust fan 11 is installed in the auxiliary pipe.

[0040] In one embodiment of the present invention, in summer, the temperature inside the air compressor room is high and cooling is required, so the second row fan 19 is turned off and the first row fan 11 is turned on. In spring, autumn and winter, the second row fan 19 is turned on and the first row fan 11 is turned off.

[0041] As an optional implementation, the cooling module includes an evaporative cooling unit 3, with air inlets 4 at both ends of the evaporative cooling unit 3, and a plurality of air supply pipes 7 at one end of the evaporative cooling unit 3, with the other end of the air supply pipes 7 connected to the machine room.

[0042] In one embodiment of the present invention, the evaporative cooling unit 3 delivers cold air to the machine room through the air outlet 20 on the air supply duct 7, thereby regulating the temperature inside the machine room.

[0043] As an optional implementation, the evaporative cooling unit 3 is provided with packing 6, circulating water tank 9 and second spray pipe 22 in sequence from top to bottom. The second spray pipe 22 is connected to the circulating water tank 9 through circulating water pump 23.

[0044] In one embodiment of the present invention, during spring, autumn and winter, the cooling module serves as a ventilation device for the machine room, and the packing 6 plays the role of filtering outdoor air. In summer, the temperature inside the air compressor machine room is high and needs to be cooled. By turning on the circulating water pump 23 on the circulating water tank 9 below the packing 6, the water is cooled by direct evaporation and then sent into the air compressor machine room by the fan, thereby reducing the temperature inside the machine room and regulating the temperature field inside the machine room.

[0045] As an optional implementation, a fan 5 is installed inside the air inlet 4.

[0046] In one embodiment of the present invention, airflow is achieved by turning on the fan 5.

[0047] As an optional implementation, the circulating water tank 9 is connected to an external water source through the water supply pipe 8.

[0050] In one embodiment of the present invention, the distance between the exhaust hood 2 and the air compressor 1 is preferably 30cm.

[0051] This invention provides a comprehensive waste heat utilization system for air compressor rooms, which, when in use:

[0052] In summer, the temperature inside the air compressor room is high and cooling is required. The second exhaust fan 19 is shut down, and the first exhaust fan 11 is turned on. The cooling module outside the air compressor room is activated, along with fan 5, circulating water pump 23, and the second spray pipe 22. In the cooling system, the target air, i.e., the air to be processed, is drawn in from both sides of the evaporative cooling unit 3. The circulating water pump 23 on the circulating water tank 9 below the packing 6 is activated, and the water is directly cooled by evaporation and then sent into the air compressor room by the fan, lowering the temperature inside the room and regulating the temperature field.

[0053] In spring, autumn, and winter, shut down the circulating water pump 23 and the second spray pipe 22, turn on the fan 5, turn on the second exhaust fan 19, and turn off the first exhaust fan 11. The cooling module then functions as ventilation equipment for the computer room, and the packing 6 filters the outdoor air.

[0054] The oil cooling system is activated year-round, specifically by opening the first spray pipe 14. Hot water collected in the water tank 12 is then supplied to the heating terminals via the hot water supply pipe 15. The cold water return pipe 16 returns from the terminals to the first spray pipe 14, spraying the oil pipe 13 for reheating, and the cycle repeats continuously. In summer, it can be used as a heat source for bathing terminals, and in winter, it can be used as a heating source for heating equipment or terminals.

[0055] This invention utilizes an evaporative cooling unit to provide organized airflow to the air compressor room during summer. The temperature field within the room is regulated and controlled by a cooling module to ensure the efficiency of the air compressor, achieving efficient convective heat dissipation and improving heat exchange efficiency. An exhaust hood 2 provides localized exhaust to the air compressor unit, removing the high-temperature air surrounding it. In autumn and winter, hot air is directly delivered to industrial workshops / factories via ductwork, providing heating for the industrial plant and recovering waste heat from the ambient air surrounding the air compressor. Waste heat from the air compressor oil is recovered year-round. While cooling the oil, hot water can be produced, which can be used as a heat source for end-point heating or bathing, achieving waste heat recovery from the air compressor oil, reducing system power consumption, and promoting energy-saving operation. This device can flexibly activate various functional sections according to different seasons and end-point needs at the location of use, achieving energy conservation and emission reduction goals.
