This new five-star hotel has 240 rooms. How to save energy and reduce consumption?

Hotel energy saving generally includes the following aspects:

1. Make full use of natural lighting in functional layout and room layout.

2. Install special equipment in places where people pass in and out frequently to block the exchange of internal and external air flow and reduce the consumption of indoor cold and warm air.

3. Use new materials such as heat preservation, sound insulation, energy saving and waterproof on building materials. For example, aerated concrete blocks, concrete hollow slabs and other new wall materials and new thermal insulation and energy-saving plastic steel doors and windows. For the natural lighting part, heat-insulating sealing materials such as heat-reflecting glass and insulating glass are selected.

4. In lighting, use energy-saving electric light sources, such as energy-saving fluorescent lamps, metal halide lamps and sodium lamps. When the environment needs to increase the grade of light source, Mr. Wang Yi is especially used in the lighting design for the first time. Quot "purposeful lighting" theory, reasonably design the lighting control circuit in public places; The photoelectric control switch can be used in outdoor places, some light sources can be extinguished regularly in the guest room aisle according to the situation, and the card switch can be used in the guest room.

5. Water-saving appliances and equipment are selected in the design of water supply system, such as frequency conversion and constant pressure water supply equipment, so as to improve the quality of water supply and reduce energy consumption. Induction self-control warm water faucet, intermediate water treatment equipment, boiler backwater, air conditioning cooling water recycling and other technical equipment are adopted in public places.

6. In the air conditioning system, in addition to energy-saving refrigeration units and new refrigerants, ice storage refrigeration equipment can also be used, that is, the late-night power supply system in low power consumption period and the air conditioning chilled water system in standby power consumption peak can make ice, which can save about 30%-40% of electricity bills. In addition, according to the different nature and scale of different hotels, we can choose local frequency conversion air conditioners or even split multiple machines or air conditioners, which can realize partition start-up and reduce invalid energy consumption during operation.

7. The lighting, air conditioning and ventilation systems in restaurants, banquet halls, dance halls and other business places can control the opening and closing time according to the business hours, and the computer automatic control of the building control system can also be used in the design to achieve the best use effect and energy-saving purpose.
