As summer arrives, the frequent use of air conditioning makes energy conservation crucial. Here are several energy-saving tips provided by the Bureau of Energy, Ministry of Economic Affairs: choose air conditioners with a high CSPF value, set the temperature between 26-28℃, and use a fan to enhance the cooling effect. Regularly clean the air filter, and install shading devices to reduce heat entering indoors. Additionally, turn off unnecessary lights and use motion sensors to save on lighting electricity. For elevators, set specific floors for stopping to reduce the number of trips. Furthermore, choosing high-efficiency appliances and cutting off power when they are not in use for a long time is also a good way to save energy. Let’s start with small actions to conserve electricity, lower expenses, and contribute to environmental protection!

Summer has arrived again, and in the face of the glaring sunlight, we often choose to turn on the air conditioning and hide indoors to enjoy the coolness. If the air conditioning needs to be on all day, are there any energy-saving methods? Here are some tips to save electricity while enjoying the air conditioning at the same time.

• Choose air conditioners with a high CSPF value; the higher the CSPF value, the more energy-efficient the air conditioner will be. Generally, for every 0.1 increase in CSPF value, you can save 2-3% of electricity.

• The optimal temperature setting for air conditioning is between 26-28℃, and it is recommended to install automatic temperature control devices to avoid wasting energy due to overly low settings.

• Clean the air filter every two weeks, as a dirty filter can lead to energy waste.

• Use an electric fan in conjunction with the air conditioner, as this can help distribute the cool air more evenly. Under comfortable conditions, you can slightly raise the temperature to save electricity.

• Turn off the compressor (switch to air circulation) 30 minutes before getting off work to reduce power consumption.

• Install blinds or curtains on east-west facing windows to reduce sunlight heat radiation entering, thereby lowering the air conditioning load.

• Ensure the air conditioning area is isolated from external air and keep doors and windows tightly closed to avoid cool air leaking out or warm air coming in.

• Avoid using central air conditioning during holidays or when there are few people, to prevent the system from operating under low load.

• Incorporate variable frequency control into the air conditioning system to effectively save electricity.

Electricity-saving tips for lighting:

• Choose LED fixtures with suitable lumen output based on illumination standards; the more efficient, the less power consumed. Using LED fixtures with energy-saving labels can save more than 50% of electricity compared to fluorescent tubes.

• It is recommended to select light-colored ceilings and walls with high reflectivity to enhance light diffusion, reducing the number of fixtures needed.

• Reduce the number of fluorescent tubes in areas with lower lighting demand, and use automatic sensing devices in high-demand areas to increase illumination.

• Implement area management, cultivate the habit of turning off lights when not in use, and set up daylight sensors to automatically adjust lighting brightness.

• In public places, install sensor switches to enhance convenience and reduce electricity usage.

• Regularly clean lighting fixtures to maintain their lighting efficiency.

• Set up area control systems to activate lighting based on need for energy-saving effects.

• Ensure the lighting brightness in spaces is moderate to avoid glare issues.

Methods for saving electricity in elevators:

• If there are two elevators, you can set them to serve odd and even floors separately to save power. If there are more elevators, it is advisable to reduce the number of elevators operating during off-peak times.

• The lighting and ventilation inside the elevator should automatically stop operating after three minutes of standby.

• When traveling between the first three floors, opt for walking instead of taking the elevator.

• When installing new or replacing elevators, choose variable frequency elevators equipped with regenerative power devices.

• The cooling ventilation system for the elevator machine room should be equipped with temperature control switches to adjust operation automatically.

Electric appliance energy-saving guide:

• Choose appliances with energy efficiency labels rated 1 or 2 and use devices that meet energy-saving standards to effectively reduce electricity consumption.

• Turn off appliances when not in use for long periods to reduce standby power loss.

• Purchase office machines with energy-saving features that can automatically enter sleep mode when not in use.

• High-voltage users must keep the power supply voltage variation within plus or minus 5% to ensure energy efficiency.

• Set up fans or air conditioning systems to facilitate transformer cooling, reducing equipment losses.

• Select appropriately sized high-efficiency induction motors to improve operational efficiency.

Small actions to conserve energy not only save money but also contribute to environmental protection!
