As summer gives way to autumn, the weather grows cooler with increasing temperature differences between day and night. Our office environment is now entering the transition period of the seasonal change. As the central air conditioning is a key facility for maintaining the comfort in the office, its usage strategy also needs to adapt with the seasons. Using the air conditioning scientifically and reasonably is not only necessary for energy conservation and cost reduction, but it also shows care for employee health and prevention..."Air Conditioner Disease" and fall colds, essential steps to maintain team vitality. In this regard, we have specially compiled usage precautions for central air conditioning during the autumn season, hoping to assist everyone in enjoying a comfortable, healthy, and efficient golden autumn.

I. Reasonably Set the Temperature  

Autumn suggests setting indoor temperatures between 22-26°C, with cooling mode not below 26°C and heating mode not exceeding 22°C.

2. Maintain an 8℃ temperature difference between indoor and outdoor to prevent "air conditioning disease" caused by sudden temperature changes.

Two: Scientifically Schedule Operation Hours  

Office hours: Daily operation from 08:30 to 22:00 (public corridors from 08:30 to 17:00).

Always turn off the air conditioning during off-hours or weekends to reduce energy consumption and equipment wear.

3. If the weather is cool, consider intermittently shutting off the air conditioning and opening windows for ventilation; this saves energy while keeping the air fresh.

III. Pattern and Ventilation Settings  

Before switching to cooling or heating mode, unify the end panel modes to prevent conflicts and shutdowns in multi-split systems.

2. The air outlet blades are positioned upwards or horizontally to prevent a direct blast of cold air on people, helping to avoid joint aches or colds.

3. Utilize the "Automatic" or "Low Speed" fan setting to reduce noise and extend the lifespan of the equipment.

Air Quality and Humidity Management  

During the autumn dry season, use a humidifier or activate the "Clean/Air Humidify" function on your central air conditioning to maintain a relative humidity between 40-60%.

2. Open windows for ventilation for 10 minutes every 2-3 hours to dilute indoor pollutants such as CO₂ and formaldehyde.

During the peak flu season, consider using a ventilation system or air purifier to reduce the risk of cross-infection.

Daily Inspections and Maintenance Cleaning  

Every two weeks, remove the return air filter for cleaning or dusting to prevent dust from blocking and affecting air volume and heat exchange efficiency.

2. Ensure no obstructions around the outdoor unit to maintain proper ventilation; report for repair immediately if any unusual noises, leaks, or refrigerant leaks are detected.

3. Conduct a thorough maintenance in the fall: clean the condenser/evaporator, check refrigerant pressure, and secure electrical connections.

Section 6: Energy-Saving and Safety Tips  

Close doors and windows, draw the sunshades to reduce cooling and heating loads; turn off the air conditioning 30 minutes before leaving the office and make use of the remaining heat.

2. Smoking and the use of open flames are prohibited in air-conditioned rooms; do not stack documents or equipment in front of vents to avoid obstructions and fire hazards.

3. When not in use for extended periods, disconnect the power and perform an on-power self-check once to ensure the system is free of faults before officially activating it.

By following these six points, you can ensure a comfortable, healthy, and energy-efficient office environment for the autumn season.
