Heat recycling system of crystalline silicon solar cell assembly lamination machine

Abstract

The invention discloses a heat recycling system of a crystalline silicon solar cell assembly lamination machine. The system comprises a controller, a centrifugal draught fan, a main air supply pipe, a main air returning pipe, an air conditioner box and a connecting pipe; one end of the main air supply pipe is connected with a box body of the air conditioner box, the other end of the main air supply pipe is connected with an air supply opening of a workshop, one end of the main air returning pipe is connected with the box body of the air conditioner box, the other end of the main air returning pipe is connected with an air returning opening of the workshop, the air conditioner box is provided with a fresh air pipe communicated with the box body, the fresh air pipe is communicated with the exterior environment, one end of the connecting pipe is connected with the fresh air pipe, the other end of the connecting pipe is connected with a hot exhaust pipe of the lamination machine, the fresh air pipe and the connecting pipe are each provided with an air valve, and the centrifugal draught fan is arranged on the connecting pipe and in front of the air valves; in winter, it can be ensured that heat of the lamination machine can smoothly flow to the air conditioner box, energy waste is avoided, the heat pollution is not caused, the phenomenon that the temperature and humidity of the air returning pipe of the air conditioner does not coincide with the environment temperature and humidity of the workshop is avoided, the control deviation problem is solved, and energy losses are avoided.

Description

technical field [0001] The invention relates to a heat recovery system, in particular to a heat recovery system for a lamination machine of a crystalline silicon solar cell module, which can make full use of the heat generated by the lamination machine during the working process in winter and reduce the heat load of the heating section of the air conditioner. Background technique [0002] A laminator is an important piece of equipment in the manufacture of solar cell modules. The laminator is used to press EVA, solar cells, tempered glass, back film (TPT, PET and other materials) into a rigid whole under high temperature and vacuum conditions. [0003] At present, the heat generated by the laminator in the photovoltaic module manufacturing plant is discharged to the outside in summer, while in winter, the heat is discharged to the outside through the heat exhaust pipe or directly enters the return air system of the air conditioner. [0004] The heat discharge method of the ...

AI Technical Summary

Problems solved by technology

[0005] ⑴The heat generated by the laminator is discharged to the outside in winter, which not only wastes energy, but also causes heat pollution

[0006] ⑵The heat generated by the laminator returns directly to the return air system of the air conditioner, and will directly enter the return air duct of the air conditioner. Since the temperature and humidity control detection probe of the workshop is taken from the return air of the workshop, it is easy to cause the return air duct of the air conditioner to overheat. Humidity does not match the temperature and humidity of the workshop environment, resulting in control deviation

[0007] ⑶ In winter, the heat generated by the laminator returns directly to the return air system of the air conditioner, which will reduce the return air volume of the air conditioner workshop environment (because the size of the return air pipe is fixed), which also causes energy loss
