Application of hotel intelligent system?

The application of hotel intelligent system is very important. The times are progressing and technology is changing with each passing day. Only by keeping up with the pace can we not be eliminated, and every detail is crucial. Zhong Da Consulting will explain the application of hotel intelligent system for you.

According to statistics, the annual energy consumption of hotels in China accounts for 6%- 18% of their turnover (usually 8%- 12% for three-star hotels, 7%- 10% for four-star hotels and 6%-8% for five-star hotels). For most hotels, energy expenditure is also the last cost that is not effectively controlled by hotels.

Among the energy consumption of hotels, air conditioning is the largest energy consumption, followed by hot water supply, and lighting electricity consumption is only ranked third.

Next, we mainly discuss the role of intelligent system in hotel energy-saving control.

First of all, the hotel lobby temperature control.

The lobby is the facade of the hotel, which is open to guests 24 hours a day and needs air conditioning almost all year round. But with the different crowds in the lobby, the air conditioning load is also different.

The distribution of people in the lobby has certain rules: in the morning, there are more passengers staying; The departure passengers are mostly concentrated at noon; The rest of the time, the passenger flow is random, so the heat load of air conditioning in the lobby fluctuates regularly with the peak time of passenger flow. The intelligent building control system can adjust the control state in advance according to the law of this load curve, adjust the operating power and efficiency of air conditioning units and water chillers according to different time periods, reduce the dynamic fluctuation energy consumption of the control system, ensure the indoor temperature comfort and realize energy-saving control.

Second, room temperature control.

The temperature control of guest rooms is mainly realized through the networking of room state control in guest rooms. When there are guests in the room, the temperature of the room is mainly adjusted by the guests themselves, so as to satisfy the guests' feelings as the first priority; However, in other rooms, such as vacant rooms, the air conditioner is not completely turned off, but 1/3 is turned on to ensure the maintenance and life of the furniture in the room and maintain the temperature balance of the whole hotel.

When guests check in in the lobby, they can automatically turn on the room air conditioner through the interface between the front desk software and the room control system, and set the room temperature to a suitable level according to the needs of different guests; After the guest leaves, the system automatically returns to the leaving state. When cleaning staff or other staff members enter the guest room, the system can adjust the air conditioner and other electrical equipment in the room to the corresponding setting state according to the identity and work content of different personnel.

In this way, the hotel can purposefully control the electrical state at the end of the room, understand the habits of the guests, and effectively avoid the situation that "the air conditioner in the room is always on or off, which makes the guests uncomfortable as soon as they enter the room".

Third, the floor temperature control

For most hotels, especially tourist hotels, there is a peak season and a low season. In the off-season, guests' requirements for temperature comfort will not change, but if all the units in the hotel are on at this time, it will cause a lot of energy consumption, increase hotel costs and even make ends meet.

In this case, relying on the self-diagnosis function of hotel management software, guests can be arranged in one or several areas, and a comfortable small environment can be created for guests only by controlling the start-up of mechanical and electrical equipment in the relevant areas.

Fourth, indoor lighting control

The indoor lighting place of the hotel can be roughly divided into three parts: business place (hall, dining room, guest room), backstage office place and public space (corridor, bathroom). Commonly used control methods are:

1. Cooperate with time sequence controller: automatically switch the lighting environment at a predetermined time, or control the lighting on and off without manual control. This device can avoid wasting electricity by forgetting to turn off the lights. For example, when going to work, after work, during lunch break, and at night, the lighting lights are automatically turned off for landscape lighting.

2. With illumination sensor: When there is sufficient natural illumination outside, the device can automatically reduce the output of the dimmable electronic controller and the brightness of the window lamp, or directly turn off the lamp. Therefore, its circuit design needs to be parallel to the window direction, which is suitable for the automatic control of window lights, window corridors, lighting wells and outdoor landscape lights at night in hotel office space.

3. Human body sensor: This device is suitable for small conference rooms, reception rooms, bathrooms and other places in hotels. The human body sensor can automatically detect the temperature of the human body in the space: when there is someone in the room, the light is automatically turned on; When no one is around, automatic turning off the lights is convenient and can avoid wasting energy, which has been widely used in domestic hotels.

4. Overall group control lighting control system: for example, central lighting monitoring system, second-line lighting control system, guest room intelligent lighting system, etc. , you can flexibly cooperate with the hotel's schedule to change the lighting requirements.

Fifth, the temperature control of equipment area and kitchen.

The equipment area includes laundry room and equipment room. These rooms are usually large in area, large in space, with many equipments and large in calorific value, and have low requirements for air comfort, but they need a lot of airflow to take away the calorific value of the equipment to ensure the work efficiency of personnel and improve the use efficiency and service life of the equipment.

Therefore, in terms of outdoor fresh air supply volume and ventilation times, it should be adjusted to a suitable range according to the space volume, calorific value and oxygen consumption of the equipment area.

Six, the air control of underground parking lot

The parking lot does not require high air quality, as long as it reaches the normal or minimum value of indoor air quality. Through manual and automatic methods, the external air intake and exhaust volume is controlled according to indoor CO2 concentration, CO concentration and smoke turbidity content, and the power supply of fans is started and stopped through the central monitoring system.

The above mainly discusses the function of intelligent system in hotel energy saving. In addition, the water consumption of the hotel is also quite huge. Due to many problems such as construction, decoration, use or equipment aging, a lot of water will be wasted. Faced with this situation, we can check the water leakage in the building by monitoring the flow of the main pipeline and the terminal flow sensor installed at the outlet of the water source, check whether there is water leakage in the delivery pipe by the difference between the flow of the main pipeline and the terminal flow, and judge whether there is long running water in the terminal faucet or toilet by the monitoring information of the terminal flow sensor.

Seventh, by using the above various controls, we can achieve:

◎ Energy saving of the system: that is, through reasonable measurement and control means, the overall energy demand, transportation and supply of the building can be balanced, and the operating cost can be saved by about 20%-40%.

◎ Energy saving of equipment: under the condition of meeting the overall requirements of the system, make all kinds of equipment work in the lowest energy consumption state.

◎ Energy-saving management: By providing various data of equipment operation, managers can accurately grasp the operating state of the system and provide humanized services for management. In addition, due to the improvement of automatic control and protection functions of facilities and equipment, the number of operation and maintenance personnel can be reduced accordingly, and the cost can be further reduced.

◎ Prolonging service life: Shortening operation time and reducing equipment load can reduce equipment maintenance and replacement costs and effectively prolong equipment service life.

In short, hotel energy saving is to maximize energy consumption under the premise of constantly satisfying people's quality of life and comfort. There are many factors that affect hotel energy consumption. In addition to the intelligent applications discussed above, the ideal energy-saving effect and effective "throttling" can be achieved by adopting multiple intelligent systems such as lighting and power optimization design, heating and air conditioning energy-saving design, rational design of energy-saving cold and hot water, building energy-saving measurement and monitoring, and building property management energy-saving grade.
