AI Technical Summary

Technical Problem

In the production workshops of cigarette manufacturing companies, the exhaust temperature of the air conditioners is close to the workshop temperature, resulting in a waste of cooling capacity. Cooling towers consume a lot of energy in high-temperature environments and also have problems with the growth of algae and bacteria.

Method used

Design an energy-saving air conditioning exhaust device. The cold air generated by the air conditioner is discharged from the workshop to the cooling tower through the air supply duct, where it exchanges heat with the cooling water. The bottom of the cooling tower adopts a conical structure to prevent water accumulation. The cooling water is circulated and cooled through the return water pipe and stored in the indoor water tank. Combined with butterfly valves and valves, the air volume and water flow are controlled to achieve heat exchange and prevent algae growth.

Benefits of technology

It improves the cooling effect of the cooling tower, reduces the operating load of the cooling tower, saves energy, prevents the growth of algae and bacteria, and optimizes the energy consumption and water resource utilization of the air conditioning system.

Abstract

This utility model belongs to the technical field of air conditioning exhaust systems, and provides an energy-saving air conditioning exhaust device, including an air conditioner, a workshop, and a cooling tower arranged sequentially and at intervals along the air supply duct. It also includes a return air duct, with its inlet connected to a section of the supply duct at the workshop's air outlet, and its outlet connected to a section of the supply duct at the air conditioner's inlet. Furthermore, it includes a water inlet pipe, a water return pipe, and a chiller. The air conditioner's water outlet is connected to the cooling tower's water inlet via the water inlet pipe, and the cooling tower's water outlet is connected to the air conditioner's water inlet via the water return pipe. The chiller is installed on the water inlet and return pipes for heat exchange of the water entering either the inlet or return pipe. This utility model improves the cooling effect of the cooling tower, saves energy, and avoids the problems of algae growth and bacterial proliferation within the device.
