Energy saving and consumption reduction of hotel energy saving management system
Energy conservation cannot be solved by "using less" and "forbearing more" manpower. For example, measures such as reducing the use time of air conditioners and reducing lighting brightness. At the same time, these measures are realized through people's consciousness and management measures, which are naturally passive energy saving, but should rely on technology to save energy. This is a positive energy saving, which can greatly save energy and resources without interfering with people's life and work, and achieve twice the result with half the effort and deeper energy saving effect.
Therefore, with the development of modern energy-saving technology, new technologies, new energy sources and new materials should be continuously adopted for energy conservation. Such as hotel room control system, wind intelligent control system. Continuous technical transformation and adoption of energy-saving technologies and equipment should consider comprehensive economic effects, so as to achieve more effective energy saving and reduce operating costs. Make the hotel's green hotel work further improved.
Indoor lighting control:
1. Add the main light in the center of the ceiling to avoid the phenomenon that the room is still dark when guests turn on the mirror headlights, bedside lamps, bar lights and table lamps. As soon as the main light is turned on, guests often stop turning on other lights. 2. Cancel the electric control board of the bedside table, directly use the big switch and install it on the bed screen. The small corridor switch controls corridor lights, bus lights and bathroom lights. Bedroom ceiling lamp, desk lamp and mirror headlight are all equipped with switches at corresponding positions, and three big switches at the bedside are enough. The middle switch panel is used to install telephone line plugs, please do not disturb. The two panels on both sides are dual-control switches, one of which is a dimming switch to control the bedside lamp. Two switch buttons: one controls rearview mirror headlights, desk lamps and ceiling lamps, and the other controls porch lamps, desk lamps and bathroom lamps. In this way, through the dual control mode of different positions, the control of lamps and lanterns is concise and lively, which is convenient for guests and can save a lot of electricity.
3. Improve the limit switch of closet lamp to avoid 24-hour ever-burning lamp. Closet doors are divided into two ways: push-pull and flat-open. In many hotels, closet doors are pushed to the bottom before going out, and guests often can't push to the bottom. Therefore, every room has a large number of lights that are always on. By improving the connection mode and position of the limit switch, guests can turn on the light with a gentle pull, and less than one-third of the lights will go out with a gentle push, so that the wall lights in the room are on only for a short time, and the other 95% of the time are off.
4. The small corridor lights should be moved to the position of the guest bed as far as possible. It is not easy for guests to fall asleep without turning off the lights, so they turn them off naturally. The bathroom light and the exhaust fan are controlled separately. Guests often turn on the lights as needed, instead of turning on the exhaust fan. As far as the lighting of star-rated hotels is concerned, the choice and demand of lighting lamps are different from those of ordinary hotels. There are several factors to be considered in the lighting of Ming-ancient hotels, and these considerations are also based on the characteristics and needs of star-rated hotels. When we paint hotel lights, we need to pay attention to the following elements:
1. Timeliness and persistence
Usually, star-rated hotels carry out small-scale innovative repairs every five years and large-scale repairs every ten years. In other words, the life of lamps must be at least ten years before they can meet the needs of star-rated hotels.
Because ordinary minor repairs will not replace lamps and lanterns, the scale of human resources involved is too large. This means that in the selection of lamps, the quality of the most heated and most stressed parts of lamps, including reflective cup cover, heat dissipation components and fixing (positioning) components, is very important.
2. Flexibility
Usually, the service life of the light source selected by star-rated hotels is about 2,000 to 4,000 hours. Therefore, during the period of 10, lamps and lanterns will need to replace many light sources. There are more than 10,000 lamps in star-rated hotels, so the replacement of light sources involves huge human resources, so the flexibility of lamps is another key point to consider. The most ideal choice of lamps is that the light source can be loaded and unloaded without touching the fixed (positioning) parts of lamps. This can not only save the replacement time, but also actively maintain the interior decoration.
3. Detail appearance
As mentioned earlier, star-rated hotels can reflect personality and tolerance, which is the success of indoor painting, but the details of the appearance of lamps are also very important. This includes all aspects of the lamp itself, such as taking the common ceiling downlight as an example, such as the spraying quality of its decorative strips, (if it is metal, what is the surface quality), the lubrication degree of the reflective cup, (if it is frosted reflective cup, the uniformity of sandblasting), and the joint tightness between the lamp and the ceiling surface (gypsum board/veneer) when it is installed in the ceiling (whether there is light leakage). In addition, by the way, in addition to hardware (lamps), installation workers (technology) are also very important, and the decoration should ensure that the lamps are installed correctly.
4. Light projection index
Star hotels should give customers a comfortable, advanced and personalized environment, so "lighting/lighting description" should try to help them express themselves and minimize the impact. Usually, the light projection indexes to be considered in the selection of lamps in the "Lighting/Lighting Description" include the following: the "cut-off angle" of lamps, the influence of glare, how to save the light source, the flexibility of the projection direction of lamps, the expandability of accessories, etc. These factors all affect the choice of lamps. In particular, the expandability of accessories should be considered thoroughly, because most of them rely on these accessories to build the whole atmosphere, such as "projection viewpoint", "color/color alignment", "glare avoidance" and "accurate projection/lighting" on projection indicators. How do hotels realize real energy saving? After reading the following content, it may be helpful to you!
The hotel intelligent room control system adopts some software control algorithms and humanized measures for automatic control of air conditioning, real-time management and service of rooms and lighting control of rooms, which not only meets the needs of guests, but also ensures the rational use of equipment, thus realizing a truly green and energy-saving hotel.
Control of energy consumption of air conditioning;
According to relevant statistics, the energy consumption of air conditioning, lighting, elevators and other systems in commercial buildings such as hotels is roughly as follows: ① Air conditioning: the energy consumption of hotel HVAC (heating, ventilation and air conditioning control) accounts for 44% of the total energy consumption. ② Lighting: The proportion of hotel lighting energy consumption to total energy consumption is 29%. ③ Elevator: The energy consumption of hotel elevators accounts for 10% of the total energy consumption.
The energy consumption of air conditioning in star-rated hotels generally accounts for more than 40% of the hotel's electricity consumption in summer. When people are used to using air conditioners in summer, the temperature is too low. In fact, the indoor temperature is adjusted to 24~28 degrees and the temperature is 40%~60%, which is the most suitable for the human body. According to experts' calculation, the power consumption can be reduced by 8% for every increase in air conditioning temperature of 1 degree. Beijing International Hotel alone can save 254,000 kWh in one summer, equivalent to RMB172,700. Every saving 1 kwh is equivalent to saving 4 liters of water, and reducing pollution discharge is equivalent to reducing 0.272 kg of carbon dust, 0.997 kg of carbon dioxide and 0.03 kg of sulfur dioxide.
In the hotel intelligent guest room control system, when the guest room is empty in summer, the room temperature is preset through the computer network, which avoids the energy waste caused by the long-term operation of air conditioning in the guest room.
For this item, according to the room budget of 30 square meters, the air conditioner in each room consumes 12 kWh, and the power consumption per kWh is 1.0 yuan. If the refrigeration temperature is increased by 2℃, the energy saving will be about 16% and about 2 kWh, that is,12x0.16x1.0 = 65438. Yuan. Take a hotel with 100 rooms as an example: one month can save 1.92*30* 100=5706 yuan, and one year can save 5706* 12=69 120 yuan.
Therefore, it is very helpful to adjust the room temperature accurately and in real time to save energy.
In addition, after the guests fall asleep, their body temperature will drop by about 2 degrees. At this time, the room temperature should be controlled at a suitable temperature, so that the guests will not catch a cold. The system will automatically adjust the temperature to 27℃~28℃ at midnight (or through the console) to save energy, which not only ensures the comfort of the guests, but also prevents them from catching cold. In other words, at this time, the air conditioning temperature of the guest room is set to sleep mode, and the energy saving of the air conditioning is truly realized. The "CAN network thermostat" in the guest control system product series perfectly realizes this. Hotel owners are considerate and caring for their guests, and also reduce energy costs for themselves.
Room service management
The service management of guest rooms mainly needs to know the habits and time of guests, realize shadow service, reduce the complaints of guests and reduce the labor intensity of waiters. According to the conventional hotel service personnel, it is 1: 1.5. Through real-time monitoring of guest rooms, the number of service personnel can be reduced by at least 65,438+00%-20%, reaching the standard proportion of international hotel management. Attendants can enter the guest room accurately and timely for daily cleaning through the system, which improves work efficiency, responds to the guest's service in time, reduces the cost of guest room management, ensures the personal and property safety and service requirements of the guests, and the network system takes effective and timely response and records, which also improves the brand effect of the hotel.
Take room 100 as an example. According to the ratio of 1: 1.5, this hotel probably needs 150 employees. If the average labor cost per person per month is about 1.200 yuan, according to the local level, six people can be reduced, and the labor cost can be reduced by at least 7200 yuan per month, which can be reduced by 8.5% in one year.
Lighting control
The hotel intelligent room control system fully considers the use of all lights in the room, whether there are people, the difference of electricity consumption during the day and at night, and the guests' electricity habits. Unused lights don't turn on, so it won't be repeated next time. The turned-on light can be conveniently turned off, which saves energy consumption and pays attention to safety.
I believe hotel owners are well aware that the right to use the room is basically given to the guests after they open the room. Even if the guests keep the electrical appliances and lights on during their stay, the hotel owner has no choice but to save energy, which obviously affects the operating costs of the hotel. In addition to the energy consumption of air conditioning mentioned above, there is also a typical situation. Due to the user's usual living habits or lifestyles, after using the bathroom, the lights in the bathroom will always be on, even until the check-out time is n hours, so it is easy for the owner to work out this account.
The hotel room intelligent control system takes this detail into account for the majority of hotel owners, and realizes the control of bathroom lighting through infrared sensors: when a guest enters the bathroom and turns on the internal lighting until he leaves after using the bathroom, the guest can manually turn off all the lighting, and it doesn't matter once the guest forgets to turn it off. The room control system can automatically turn off all the lighting in the absorption room after the user leaves for ten minutes through the infrared sensor.
starred hotel
Note: The above ratio is based on the overall decoration of hotel rooms.
To sum up, the one-time investment of the passenger control network management system is higher than that of the conventional system, but its direct and indirect benefits are obvious. According to preliminary statistics, the annual return rate of using the hotel room intelligent control system is 200,000 RMB.
In terms of future maintenance
The hotel guest room intelligent control system adopts modular system structure, which disperses different functions of the guest control system into various modules, and changes the disadvantages of the traditional host mechanism of the guest control system: once the equipment fails, the whole back-end system equipment cannot continue to run, and at the same time, the troubleshooting efficiency will be reduced in the maintenance of the maintenance machine. The modular system structure and functional module failure of the guest room control system will not affect the normal operation of other functional modules, and the troubleshooting is more convenient. At the same time, the plug-in connection mode of passenger control system makes it easier to maintain and replace the equipment.
