This utility model relates to the field of fresh air device technology and discloses a self-controlled anti-freeze temperature control device for fresh air units, including a fresh air unit box with functional partitions on both sides inside the box. This utility model uses a fresh air temperature sensor and a secondary fresh air sensor to detect the fresh air temperature, and an exhaust air temperature sensor to measure the exhaust air temperature. A temperature controller controls the electric heater to turn on, ensuring that the average temperature of multiple sensors is higher than the anti-freeze threshold. This provides both anti-freeze protection and energy savings. When the temperature is too high, the temperature controller can control the exhaust fan and exhaust impeller to utilize sensible heat recovery for auxiliary pre-cooling, reducing the cooling load on the cooling coil. When the temperature is too low, the exhaust fan and exhaust impeller stop operating, avoiding unnecessary equipment operation. This allows the device to automatically adjust and control according to temperature changes, providing excellent anti-freeze protection and being energy-efficient and environmentally friendly, greatly reducing the waste of electrical and thermal energy.

This invention provides a carbon fiber encapsulation tube shell surface spraying treatment device, belonging to the field of spraying processing technology. It includes a control unit and a suction module installed at the outer end of the central groove, which automatically starts after the spraying operation is completed. This module quickly generates negative pressure in the internal groove, which rapidly sucks up residual spray material from the spraying channel inside the nozzle, preventing residual spray material from accumulating and dripping due to gravity. This design eliminates the risk of residual spray material adhering to the surface of the sprayed or unsprayed carbon fiber encapsulation tube shell from the source, effectively avoiding defects such as local bumps, color differences, and uneven coating thickness. It also solves the problem that after a single spraying operation, residue in the spraying channel inside the nozzle gradually accumulates and drips downwards due to gravity. This dripping spray material residue easily adheres to the surface of the sprayed or unsprayed tube shell, damaging the uniformity of the surface coating and causing the encapsulation tube shell to fail to meet the designed surface performance indicators, significantly increasing the product defect rate.
