How do hotels save energy and reduce consumption?

We know that a hotel with 100 rooms, if the annual occupancy rate is around 70%, the annual water and electricity costs will be at least 700,000. If we use our equipment, the cost of water and electricity will be reduced by more than 654.38+0.5 million, accounting for 25% of the total cost. Moreover, our system adopts wireless transmission technology, which will not destroy the existing decoration, and will be independently constructed in the room, which will not affect the normal business of the hotel. If you are interested, I will detain you for a few minutes and give you a brief explanation. Air conditioning energy saving

Air conditioning is a big energy consumer in our hotel, and guests will have some bad habits when using air conditioning. For example, in summer, many guests will set the temperature of the air conditioner to the lowest, such as 16 degrees Celsius, so as to reduce the indoor temperature as soon as possible after entering the room. But 16 degrees Celsius is not the temperature he needs. When the indoor temperature really drops to 16 degrees Celsius, he may feel a little cold, even his hands and feet are cold. At this time, someone will think of correcting the temperature of the air conditioner. But more people will use clothes and quilts to keep out the cold, and will not think of correcting the air conditioning temperature. What kind of waste is this for us? There is an authoritative experiment. When the outdoor ambient temperature is 37 degrees Celsius, the air conditioning energy consumption of a 25-square-meter room is tested. The results show that when the air conditioning temperature is set to 22 degrees Celsius, the daily power consumption is 30 degrees Celsius. However, if the temperature is set to 25 degrees Celsius, the daily power consumption is only 15 degrees. The data mentioned in the experiment is 22 degrees Celsius. If our guests adjust the air conditioner to 16 degrees or 18 degrees, the wasted electricity can be imagined.

In this regard, the measures we take are to collect indoor temperature data by using a temperature and humidity probe, the host sends out a weak signal to automatically correct the air conditioning temperature, and adopts a gentle way to correct the temperature change curve, so that the temperature gradually approaches the most comfortable temperature of the human body. At present, the national standard of the most comfortable temperature for human body is 26 degrees Celsius. Of course, our system can set this temperature standard according to different needs. Through this amendment, the comfort of guests has been improved unconsciously, and at the same time, our energy consumption in air conditioning will be greatly reduced. In addition, when the guest falls asleep, our system will make a judgment and automatically switch to sleep mode. If the air conditioner itself has no sleep mode, the system will make it work in the working principle of sleep mode, thus achieving the purpose of energy saving.

Four. Transformers (movie name)

Transformers are widely used in the hotel industry, but most hotels will ignore the energy consumption of transformers themselves, let alone start to save energy from this aspect. Transformer has two important indicators, one is the optimal load interval, and the other is the three-item load balance. If the transformer deviates from these two indicators for a long time, one is that its own energy consumption increases, and the other is that the transformer heats up or even burns down.

The optimal load range of a transformer is generally between 75% and 85% of its own capacity. If the transformer load is lower than this range, the energy consumption ratio of the transformer itself will increase, resulting in waste. Above this range, the overload of the transformer will generate heat, which will affect the service life and burn out in severe cases. Our system will make the transformer in the best load range as far as possible by adjusting the electrical equipment that can be used for delay. As we all know, commercial electricity consumption is time-sharing pricing. During the period from 12 in the evening to 7: 00 the next morning, the electricity bill is about 40% of the daytime. Suitable for single electric water heaters, freezers, high-level water tanks and other energy storage devices. , the system will automatically arrange them to start at a low electricity price to save electricity and make the transformer in the best load range to the maximum extent.

The input of the transformer is completed by three branch lines and a zero line. If most of the power is input through a branch line, the load of this branch line will be great, and the energy consumption of the transformer itself will also increase, which may burn the line. What we need to do is to balance the loads of the three lines as much as possible. For example, suppose that the power supply on the first floor of our hotel 1 is completed by line A, the second floor by line B and the third floor by line C. 1。 There is a guest room in use on the second floor. If guests come to stay at this time, the system will automatically assign them to the third floor for accommodation, so as to balance the three-floor load, reduce energy consumption and prolong the service life of the transformer.

guest room

Guest rooms are the places where guests spend the most time. Many guests think that I have spent money and I can use it as I want, so there will be a lot of waste. For example, when guests use the bathroom, they will turn on the light intentionally or unintentionally; Turn on the ventilator and leave it on for a long time, thinking that the air will circulate; Don't charge the card when you go out. All these situations will cause a waste of energy.

For these phenomena, our system treatment method is: through the infrared probe, the bathroom automatically turns on the light when someone is there, and automatically turns off the light when people leave; According to the size of the room and the specifications of the ventilator, determine how many minutes after the ventilator is automatically turned on, so as to achieve the purpose of ventilation with the least electricity; In addition, the system can also judge whether the guest is still in the room through infrared probe and door magnetism. If it is judged that the guest is out, the room will be cut off and the power will be automatically supplied when the guest returns to the room. Through this treatment of our system, we can effectively put an end to these wastes, thus achieving the purpose of energy saving.

. others

For other hotel facilities, such as public area lighting, underground parking, night lights and neon lights, fountains, restaurant lighting, air conditioning, etc., our system can be automatically controlled, so as to automatically turn on when there is demand and turn off when there is no demand, so as to reduce energy consumption. As for boilers, because we don't know the exact demand, supply often exceeds demand. For example, 20 tons of water were burned today, but only 65,438+00 tons were used, and the remaining 65,438+00 tons were left to cool in vain, resulting in a waste of energy. Our scheme is to install a sensing system at the front end of the boiler, accurately know the water consumption at the next moment through the accurate calculation of the system, avoid the above waste, and at the same time, achieve the effect of energy saving by changing the speed of the boiler induced draft fan.

. water

Leakage in the bathroom is a common situation in hotels, and it is not easy to be found if the leakage is not serious, but every little makes a mickle, which is also a waste for us. Our system can accurately detect the water leakage in any link of the guest room and give an alarm, so as to timely repair and stop leakage and prevent energy waste.

summary

Our annual saving of 25% is a conservative figure, because this 25% does not include: employee energy efficiency assessment, transformer energy saving, water leakage monitoring and other aspects that are difficult to quantify. According to the usage of the last customer, Frontier Hotel, their energy saving effect can now reach about 365,438+0%, so I believe that if we have the opportunity to cooperate, your hotel will also achieve satisfactory results in energy saving.
