The new backwind mixing section ① The outdoor fresh air and indoor reflection are mixed in this function section, and the hot and cold exchange is performed to convert the air into another new work point.② The new backwind mixed section can be set up with an electric adjustment valve to regulate the proportion of new backwinds.Through the new wind temperature sensor and the air -to -air temperature sensor, the open angle of the new wind valve and wind return valve is automatically adjusted after calculating the central processing unit.2. The initial effect filtering section of the new group of the new group is the primary filtration of the outdoor fresh air and indoor return wind. It uses a bag filter or plate filter.① The filter material of the initial efficiency filter uses non -woven fabrics, the filter filtering level is G4, and can be filtered with dust with a particle size of ≥1 μm. The filtration efficiency (atmospheric dust counting method) is 80%, and the initial resistance is 60Pa.The medium -efficiency filtering level is F8.② The filter needs to be cleaned regularly. Pressure probes can be set on both sides of the filter, and a pressure difference can be set up.③ The filter section is dismantled, and the fixed card spring that is easy to disassembles is installed on the sealing activity framework. The framework is made of galvanized plate.3. The cold section of the new group is the key components of the air -conditioning unit.① The refrigerator is a copper tube skewers aluminum sheet. The aluminum sheet is made of a special mold stamping. After stamping through mechanical stamping, the secondary edge process is used.At the same time, the surface is not easy to accumulate ash, and it is easy to clean, preventing the germs from breeding on the wings.② Pipeline opening: The pipe port mechanical expansion process not only ensures the welding strength, but also reduces defects such as piping tube leakage, and improves the overall strength and sealing performance.③ The copper tube used in the cooler is a copper tube. The specifications φ16 × 0.5/0.75㎜ and φ12.7 × 0.135/0.15㎜ Copper pipes; the winged material is 0.135mm (0.12mm thick) aluminum foil with 0.135mm (below 40000m3/h).④ Reasonable pipe distance, discharge, splittering, increase heat exchange area, and improve heat exchange efficiency.⑤ The plate tube uses seamless copper tubes to swell with double -edged high -efficiency aluminum wings.Copper tube is arranged in staggered, with double -edged high -efficiency aluminum wings, ensuring that the plate has good thermal transmission performance and low air resistance, and ensure reasonable water flow speed and balance of water side cold and wind side cooling volume.Relationship, give full play to the heat exchange ability of the cooler.⑥ The water plate of the table is made of high -quality steel plate.There are galvanized steel pipe interfaces with tape thread at a lower water tray to ensure that the condensate is unobstructed.⑦Cin seamless steel pipes as water collecting pipes, set up airworthiness valves on a higher part of the pipe pipe water collecting pipe to eliminate the residual air in the early stages of running in the heat exchanger to ensure that the heat exchanges are not affected;Set up a drainage outlet to avoid frozen and cracks of heat exchangers to ensure the safe operation of the unit in winter and summer.
