Energy-saving measures of hotel buildings

The energy-saving tail of air conditioning system should be designed by itself. Wentong personnel should communicate with architectural designers, and should not ignore the thermal insulation consequences of building materials and structures while considering the appearance of the building; The design of air conditioning system should combine the use characteristics and conditions of different areas of hotel buildings, select reasonable design parameters, comprehensively consider the requirements of natural ventilation and lighting, and reasonably select air conditioning system and cold and heat sources; It is also an ineffective and energy-saving method to replace small temperature and large flow with large temperature and large flow in the design of water system, and it is absolutely forbidden to use regulating valves for water regulation. After the owner moves in, the indoor temperature parameter can be increased by 2℃, and the materials suggest that the design temperature of air-conditioned rooms in winter is reduced by 1℃, which can extend the electricity consumption by 8%.

3. Unify the measurement of energy consumption and do a good job in agricultural protection.

In view of the hidden proportion of hotel building energy consumption, combined with the actual operation of the original two places, the answer to electricity consumption is analyzed from the above circles.

As a dual energy consumption, hotels should keep pace with the times and adopt some old-fashioned energy-saving technologies, such as temperature dryness control technology, floor radiation technology, solution drying technology, lunar energy dissipation technology, warm pump technology and two main pumps technology. On the one hand, it contributes to the country's energy conservation and emission reduction, on the other hand, it also contributes to the thrifty opening of hotels.

With the progress of our career level war on quality and quantity demand, the share of building energy consumption in Zibung's electricity consumption has not reached 30%, and it has a downward trend with the northward movement of heating demand and the southward movement of air conditioners. As a small-scale parent building, the hotel building is not a big energy consumer, and the energy consumption of temperature collection, air conditioning and ventilation accounts for less than 65% of the building energy consumption. Therefore, it is ineffective to take a lot of energy-saving measures to reduce building energy consumption.

Lighting, air conditioning and elevator are the major systems of hotel energy consumption. The main answer of the lighting system is: lamps are used to store their own works, which is in an ignorant state, not only wasting electricity, but also prolonging the life of lamps; The important problem of air conditioning system is that the equipment selected in the system, especially the hot water unit, water pump and other equipment, has great choice in design, and only needs euphemism in actual use, which is beneficial to operation and adjustment, resulting in the waste of cold and heat; The elevator system has also been able to make considerable zero adjustment according to the number of people and the time period, so that the elevator runs without load.

4. Lack of heat to support installation

The hotel is inefficient in construction and use. In order to meet the requirements of outdoor temperature and dryness without the same function, it is necessary to equip air conditioning units, majestic coil units, old majestic units, boilers, fire pumps and other secondary supporting measures for heating, water and electricity. The lack of enclosed materials implies that electricity consumption accounts for about 60% in addition to energy consumption under construction. 70%, mainly non-coal or oil, accounting for 30%? 35%。 To put it bluntly, the importance of energy consumption lies in lighting, elevators and air-conditioning systems, and the air-conditioning system has the smallest proportion. Xia Dong's electricity consumption in two seasons accounts for 60% of the electricity consumption, which is equivalent to the shutdown in the zero quarter.

Some hotels, especially small hotels, use effective heat for collection and installation, such as low-temperature flue gas from boilers, exhaust heat from ventilation systems, condensed water from many heat exchange equipment such as air conditioning, heating and bathrooms. The heat of the water is ignored and ineffective, which not only purifies the outdoor environment, but also increases the input of energy consumption and saves the use of sewage. In addition, the leakage of steam and other media, uneconomical pipeline layout and poor thermal insulation effect increase the energy consumption of mining and transportation and reduce the use efficiency of media.

3. The equipment system lacks the necessary energy consumption metering system

As for hotel buildings, frankly speaking, steam will be used in bathing, tableware washing, temperature collection and other links. The following steam recovery methods include open and closed water tank recovery systems and condensed water recovery systems. The low-temperature gas produced by steam boilers can also be collected and utilized by the corresponding boiler flue gas waste heat recovery facilities, and the use of ordinary plate heat exchangers can reduce a sanitary hot water department. In addition, the refrigeration unit with heat recovery can reduce domestic hot water and increase the capacity of the thermal cooling tower by recovering the condensation heat in winter.

2. Adopt advanced automatic frequency conversion technology and lighting measures to adjust the running time every hour.

1. Unreasonable architectural design

With the implementation of China's energy conservation and emission reduction policy, energy audit has been paid more and more attention by government departments. However, many hotels have paid enough attention to this, and a few devices do not have a perfect metering system, so it is easy to find problems in equipment operation and correctly analyze energy consumption. Cooling water of air conditioning system, and water consumption of laundry room, vegetable washing room, employees and farmers bathing, etc. All of them are measured by separate displacement meters, so that only one total water consumption is used for zero building, and the return flow and usage of water resources are easy to calculate. The setting of electric meters and steam meters also died of similar problems.

At one time, the design and construction of hotels only paid attention to the splendor inside and outside, and rarely used building materials such as glass curtain walls to make visual consequences, ignoring the thermal insulation effect of building materials and the purification of rural light. Seeking the underground lobby in an all-round way will lead to waste of space, large specific work between windows and walls, unreasonable air distribution, good environmental consequences and waste of energy consumption. Some buildings suddenly can't use natural light in the morning, and they need to use lighting ability during the day to meet the lighting requirements; In addition, the actual temperature of the air-conditioned room just meets the design parameters, and there is a feeling of hot air blowing in winter, but it is necessary to open a window to collect heat in summer.

For air conditioning system, terminal equipment such as refrigeration unit, water pump, fan, etc. Methods such as variable flow rate and temperature can be adopted to stop the hourly air conditioning and joint static control according to the change of outdoor environment and the situation of outdoor personnel, which will not affect the demand and supply of outdoor personnel, but also save energy consumption. In addition, in the choice of lighting measures, whether to use energy-saving lamps such as fluorescent lamps, tungsten halogen lamps and LED lamps, and whether to borrow acousto-optic controlled lamps or other energy-saving lamps and facilities unconditionally.

In view of the characteristics of energy consumption in hotel buildings, and the air conditioning system is the largest energy consumption in hotel buildings, it is not necessary for people to explore practical energy-saving methods for hotels and come up with ways to improve the application rate of energy-saving flow in water saving, electricity saving and solar terms (coal or oil).

The formation of hotel energy consumption and its countermeasures

4. Add cold reflux device

5. Use external fire to eradicate stagnant water and drop less water.

6. Adopt the old HVAC energy-saving technology.

A large amount of sewage produced by bathing, washing and air conditioning during hotel construction can be reused after simple re-precipitation, filtration and chemical treatment, such as blue sky irrigation and air washing. In addition, the toilet uses a toilet with low flushing quality, which has a different effect when it is small. Whether to take a bath by swiping your card can avoid the waste of water resources and the hidden phenomenon of less dripping.

2. Unreasonable equipment configuration and operation management.

1. Start the design and close the design.

When building a hotel, it is necessary to establish a healthy energy consumption measurement system, which requires important energy-consuming equipment, such as feed water pump, royal machine, refrigeration unit, lighting lamps, boilers and so on. Install power measuring and testing instruments to immediately check energy flow and calculate energy saving effect. In addition, the protection of all kinds of equipment is also very important, especially all kinds of non-boiler disassembled pipes and cooling equipment of central air conditioning system should be washed on schedule to attack scale and fight corruption.
