Hotel energy saving knowledge

1. What are the ways to save energy in hotels?

Hello! Hotel energy-saving methods 1. Use water-saving toilets.

Using water for bowel movements and guiding guests to use it correctly can save more than half of the water. 2. Gradually phase out the traditional toilets with more than 9 liters and replace them with 6 liters, or install a water-saving core in the water tank. , each toilet can save about 30 tons of water a year, or use the local method, put a 1.25 liter Coke bottle in each water tank, the occupancy rate * the number of rooms * 1.

25 liters * average number of uses = water saving 3. Intelligent sensor water-saving faucets can be installed in employee bathrooms. Male employees can take baths for 8 minutes and female employees for 12 minutes by swiping their cards to control water consumption 4. Public bathrooms You can install an induction water-saving faucet, and a flow-saving water faucet can be installed in the bathroom. Appropriate control of the water flow can save 1/3. 5. Reuse of reclaimed water. Hotels can recycle part of the wastewater and use it through sedimentation and filtration to irrigate green spaces, wash cars, and cool down... 6. Many foreign hotels have rainwater collection systems.

After processing and reuse, resources will not be lost in vain. 7. Use reminder cards to guide customers to change cotton fabrics once a day instead of changing them once a day.

8. Create a water-saving atmosphere and use vivid forms to remind guests and employees. For example, some foreign hotels place reminder cards in the room: one cup requires 4 cups of water to clean, etc. 9. On each aspect of the hotel Water meters are measured in each area of ??the business department, and the accumulated data determines the reasonable water consumption based on the usage rate. 10. Establish a system to mobilize employees to develop good habits, strengthen inspections of water, electricity, oil, and steam leaks, and prevent water from running when lights are on. According to testing, the waste caused by leakage and leakage in domestic general enterprises is about 5%-10%. 11. Condensed water recovery, steam turns into condensed water, the water temperature is still 70-80 degrees, and each ton of condensed water contains about 6 kilograms of light oil combustion of heat, a medium-sized hotel can recycle 5,000 tons of condensed water in a year. 12. The cooling tower of the hotel will form a large amount of water mist. This inconspicuous water mist will float away 60 tons of water in a medium-sized hotel, or 5,000 tons of water in a year. It can By changing the angle of the air flow and installing a water collector, the loss can be greatly reduced 13. Use new energy-saving light sources. Although energy-saving and other energy-saving lamps are several times more expensive than traditional white woven lamps, the luminous rate is 4-5 times higher and the service life is longer 8- 10 times, it is completely economically feasible. If the hotel uses all energy-saving lamps for lighting, it can save at least 70% of electricity. Moreover, the spectral chromaticity of energy-saving lamps is now close to that of white lamps, which does not affect the atmosphere.

14. A large number of various types of sign indicators and night lights in the hotel can use light-emitting diode LED lights, each of which consumes less than one watt. 15. Sensor energy-saving lamps should be used in corridors and fire stairways to prevent the appearance of constant lights. Some foreign hotel guest passages also use sensor lamps. Only a few lights in front of you are on, and the lights go out when people pass by.

16. Using intelligent power-saving voltage-regulating switch systems, public areas of hotels, such as lobbies, conference halls, multi-function halls, and banquet halls are often equipped with hundreds of light bulbs. This system can adjust voltage and brightness according to sunlight conditions and atmosphere creation needs, saving about 20% of electricity.

17. Combination lamps can be controlled by multi-switch groups. Choose different modes according to your needs.

18. In the hotel engineering design specifications, large power consumers such as refrigeration units, water pumps, elevators, boilers, fans, etc. generally have a 30% surplus power. There is generally a phenomenon of "big horse-drawn cart" during operation.

Using a frequency conversion system, the motor speed frequency can be adjusted according to temperature and load changes, generally saving 30-50% of electricity. Since the power store is the bulk of the hotel's consumption, the investment in equipment can be recovered in less than two years.

19. Install solar panels on roofs and walls according to local conditions to provide and supplement power for hotels. my country's energy strategy proposes to become a major country in the manufacturing and use of solar panels within ten years, and encourages the use of solar energy across national borders.

20. my country’s average sunshine is greater than 2,000 hours. Newly built hotels can achieve the functions of collecting, storing and distributing solar energy based on the optimized design of the building itself.

Solar water heater, solar energy harvesting, solar refrigeration, solar power harvesting... Each square meter of solar panels can save 800 degrees of electricity and 3,000 kilograms of standard coal a year.

2. Common sense about energy conservation and environmental protection

With the rapid development of today's society, science and technology are becoming more and more developed, and people's living conditions are getting better and better. But behind a happy life , but it hides a series of problems and disasters.

If nothing else, let’s just talk about saving energy. Some people may say: We have already paid attention to this issue, and everyone is saving energy, so stop talking empty words here. It is really a cliché.

That’s what they say, but have people really noticed energy conservation? Question: If people really pay attention to energy conservation, why will the forest area continue to decrease for no reason? Why is white trash still flying all over the sky? Is this just empty talk? Therefore, we should have a new understanding of energy! Energy can be divided into two types, one is renewable energy and the other is non-renewable energy. Renewable energy refers to energy that will never be exhausted with the operation of nature. Non-renewable energy refers to its consumptive nature and its reserves are limited. , will gradually reduce, and the energy can no longer be used after it is used up. So, as ordinary people, how do we save energy and how do we start from around us? 1 Water: If the faucet leaks after being used for a long time, cut a gasket that is the same as the original one from the rubber cap of the small medicine bottle containing penicillin and put it in to ensure that there is no leakage.

Use a shower head when taking a bath, which saves up to 80% of water than using a bathtub. When taking a bath, you should avoid showering for too long, turn off the water in time when scrubbing, and do not leave the water on the nozzle all the time. When multiple people are taking a bath, do not interrupt one connection after another, which can save the loss of cold water before waiting for the hot water to flow out. .

Do not flush, wash dishes, vegetables, or laundry directly at the faucet. You should put an appropriate amount of water in the basin for washing to reduce loss. Use rice washing water and noodle cooking water to wash dishes and chopsticks, which can save domestic water and reduce cleaning pollution.

Use vegetable washing water, laundry water, dishwashing water and bathing water to water flowers, wash cars and scrub floors. Wash vegetables with rice washing water first, and then wash them with clean water. This not only saves water, but also And it can effectively remove residual pesticides on vegetables. 2 Computer: If you do not use the computer for a long time, you can turn off the computer host and monitor. During a short break, try to enable the computer's "sleep" mode. After shutting down, be sure to unplug the power plug. , otherwise it will not only waste electricity but also shorten the life of the computer. When listening to music or watching DVDs on a computer, it is best to use headphones to reduce the power consumption of the speakers.

3 TV: The brightness and volume should be adjusted to the best state for people's perception. Don't make it too bright and the volume should not be too loud, otherwise it will consume a lot of power. After the TV is turned off, the power supply should be cut off and the plug should be unplugged from the power socket.

4 Lights: The lights consumed in a typical home can account for 15% to 20% of the household electricity bill, so you should only use them when needed and turn them off when not in use; purchase new ones When installing lighting, please try to consider energy-saving bulbs. Fluorescent lamps have the characteristics of high luminous efficiency, soft light, long life, and low power consumption, so try to use fluorescent lamps instead of incandescent lamps. Light and high reflectivity lamps should be used in the main living areas of the home. Decoration colors and choose light-colored lampshades with high light transmittance, and keep lighting equipment and bulbs clean to achieve maximum lighting efficiency. 5. Air conditioner: Many people adjust the temperature of the air conditioner too low. In fact, you only need to adjust the cooling temperature to an energy-efficient temperature to make your family feel comfortable rather than cold.

During sleep, human metabolism is reduced by 30-50%. You can set the air conditioner to the sleep switch and set the temperature 2 degrees higher to save 20% of electricity. It is best to set the indoor and outdoor temperature difference is 4 to 5 degrees. Clean the air filter frequently.

When sleeping, use the timer function to close areas that do not need air conditioning, and turn off air conditioners in areas where no one is using them; Seal the gaps in doors and windows to avoid the loss of air conditioning, and this should be effectively avoided in summer Direct sunlight can save about 5% of electricity; use time switches to switch air conditioners on and off as much as possible; install air conditioning piping properly. The piping of the air conditioner is short and not bent, has good cooling effect and does not consume electricity; the air outlet remains smooth.

Do not pile up large pieces of furniture to block heat dissipation and increase unnecessary power consumption. 6. Refrigerator: The refrigerator is set at 5°C and the freezer is set at -6°C. The refrigerator is in the best working condition and the most energy-saving. When purchasing a refrigerator, you should choose a model with high energy efficiency.

Single-door refrigerators are the most energy-saving, followed by double-door refrigerators with upper and lower compartments, and then left-right double-door refrigerators. The capacity of the refrigerator should also meet the needs of your family; the refrigerator should be avoided Do not place it in direct sunlight or near a stove or any other heating object; Do not adjust the refrigerator to an unnecessary cold temperature as this will only waste electricity; Do not put high-heat or warm food in the refrigerator , the food should be cooled to room temperature first; the refrigerator should not be opened and closed too frequently; to defrost refrigerated food, food should be moved from the ice tray to other refrigerated compartments the day before cooking; keep it clean to avoid dust accumulation that causes the temperature to rise; go out far away Before leaving, clean out all food in the refrigerator and turn off the power. 7 Washing machine: The machine should be filled with clothes before washing, because half full and full use the same amount of electricity; try to use low-temperature washing procedures, and do not use too much detergent; especially before using the dryer, use high speed The spin dehydration program is more energy efficient.

8 Cooking: use high fire for stir-frying and steaming steamed buns; use slow fire to make soup and pancakes until the food is fragrant. After the food boils, turn down the heat and keep it at a slight boil; when steaming, generally steam It is appropriate to leave half a bowl of water at the end; the water heats up slowly, so use low heat first, and then turn on high heat after the water temperature rises; choosing a cooker with a larger diameter can reduce heat loss. 9. Fuel saving: After starting the car, get on the road as soon as possible. Do not let it warm up in place for a long time. The engine will heat up faster while driving than if it stays in place. Keeping the car running at a constant speed can make full use of the fuel. Frequent changes in speed will To avoid wasting fuel, sudden acceleration and braking should be avoided.

According to research, the speed at which fuel can be most fully burned is 40 to 100 kilometers per hour; do not develop overly intense driving habits such as starting suddenly, slamming on the brakes, giving fuel suddenly, and turning the direction suddenly. This not only consumes fuel, but is also harmful to the car; some people are used to putting things in the car. Overweight vehicles will consume more fuel when driving. Try to empty the trunk as much as possible and don't use it as a storage room. 10. Refuse plastic bags: Refuse plastic bags, use cloth bags, and try not to use disposable chopsticks.

All of the above are things that can be done in daily life, as long as you are careful and have a sense of crisis and responsibility.

3. What are the hotel’s energy conservation and emission reduction measures?

The hotel should conduct a detailed analysis of the water, electricity, and thermal energy systems, and establish an energy usage and consumption database to provide a basis for the implementation of quantitative energy management. =Elevate energy management from qualitative to quantitative through daily monitoring and meter reading of energy metering devices, and analyze the hotel's water, electricity, gas, and heat energy conditions monthly, and make charts based on the hotel's operating income, compared with the same period last year Compare and contrast and propose energy-saving suggestions and measures to help and guide the hotel's rational use of energy.

Clear responsibilities are the basis for energy conservation and consumption reduction. Hotels can implement quota management based on the analysis results, decompose usage indicators and energy-saving indicators into various departments, adjust and control the energy consumption of each department; improve the monitoring system, implement segmented control and calculation, analyze data indicators based on operating conditions, and respond to abnormalities. The situation should be tracked and dealt with in a timely manner; the maintenance of the water supply system of the pipe network should be strengthened, and loopholes should be tracked through data analysis to reduce the occurrence of running, rising, dripping, leaking and long running water.
