Good hotel energy-saving service scheme

First of all, the electricity consumption of the hotel.

With the rapid development of the tertiary industry, as a typical power service industry, the number has increased rapidly and the competition has become increasingly fierce. Most hotels and other enterprises are facing the situation of falling profits. In order to provide a comfortable environment for the guests, there are not only photoelectric lights, televisions, refrigerators, air conditioners, water heaters and other electrical equipment in each room. If all of them are turned on, the power will exceed 2,000 watts. That is to say, if a passenger is in the room, all the electrical equipment will be turned on, and the power required for one hour will exceed 2 degrees.

A common indicator of international hotels and other industries, the electricity allocated to each room on this day is 23 to 26 degrees. This is a hotel with 65,438+0,000 customers. The cost of consuming about 23,000 to 26,000 industrial electricity every day is a major cost control cost. Electricity has become a necessity for hotels, but it is also the most effective means to reduce hotel operating costs and improve the competitiveness of the industry.

Analysis of electrical symptoms in a hotel

(1) The energy consumption of the power transmission and distribution system is serious.

1, due to seasonality or tourist season, it is inefficient in power grid.

When the hotel occupancy rate changes greatly, the load rate of the transformer is generally not high, sometimes there is almost no load running, and the high voltage change rate causes the transformer's own loss and unnecessary waste.

Large loss of power supply line

Due to the long transmission distance, large apparent power and many branches of the power cord of hotel electrical equipment, the influence of a large number of losses and thermal resistance line losses is concentrated, which leads to the decrease of terminal voltage and energy efficiency, and there are certain security risks;

3, poor power quality, the number and variety of hotel electrical equipment, power electronic devices, electrical appliances using nonlinear loads, resulting in serious load nonlinearity, voltage waveform distortion, poor power quality, greatly reducing energy efficiency, but also affected the service life and safety of electrical equipment.

(B) The utilization rate of energy-consuming electrical equipment is not high.

The guest room is equipped with mixed load line electric lighting, TV, water heater and other water machines.

Most of the lighting equipment is still old-fashioned incandescent lamps, which consume a lot of energy;

B, all electrical equipment in single-phase power supply is a serious three-phase unbalanced line, resulting in excessive zero-sequence current and increased energy loss.

C. working electricity? The general pressure is higher than the rated value, which can not only make lighting, water diversion, water heater and other equipment more efficient, but also lead to equipment heating and premature failure, waste energy and reduce the life of electrical equipment.

2. Air-conditioning equipment (cabinet or central air conditioning) First of all, most of the design choices of hotel air-conditioning systems are expected to maintain a deposit of about 20%, but due to the influence of room occupancy rate,

Rarely run at full load; Second, the air-conditioning circulating water system actually runs at a fixed maximum design flow rate, and does not change with the load, so it cannot realize reasonable dynamic automatic adjustment of the main engine, auxiliary equipment and comfortable temperature, resulting in low utilization rate of generated electric energy and serious energy waste.

(3) The guests have strong energy-saving awareness and simple energy-saving management.

The profitable business of the hotel, the customer base it faces, temporary accommodation abroad, ubiquitous money, and the psychology that consumers don't need, coupled with the fate of the hotel room and the timely monitoring of electricity consumption, is because there is a ever-burning lamp there during the day, and the phenomenon of forgetting to turn off the lights, televisions and other electrical equipment when going out leads to very serious energy waste. At the same time, most hotels manage the overall energy use from the perspective of guest demand, but from the perspective of supporting the normal operation of equipment, rather than from the perspective of efficiency, energy consumption standards, equipment service life and so on, the energy utilization rate is low.

Hotel preservation system.

(1) Project design
