Hospital construction engineering energy-saving improvement technical measures
As the function of the hospital is more and more perfect, the standard of the construction engineering is also greatly improved as a result, and the construction engineering of the hospital has thus become the main energy-consuming building. Below I share with you the technical measures to improve energy conservation in hospital construction projects, welcome to read and browse.
Analysis of the current situation of energy consumption in hospital construction
Hospitals are progressing with the times, whether from the aspect of medical technology or the construction of hospital buildings have improved very much. Because of the special characteristics of the hospital, resulting in its energy consumption is greater, but the formation of this reason is not always reasonable. There is nothing wrong with adding new medical equipment, improving the medical environment, and perfecting medical functions in hospitals. However, some hospitals are overly concerned about the appearance of the magnificent, blind pursuit of hospital grade, the addition of unnecessary facilities, etc. is obviously not reasonable. According to the statistics of the relevant departments, the hospital and building-related or indirect energy consumption reached more than 54%, for the U.S. hospital buildings, buildings used to 1/3 of the electricity, lighting used to 1/5 of the electricity, China's hospital construction level compared with the U.S. There is still a certain gap, so for the energy consumption of hospitals, hospitals, buildings consume a larger proportion of electricity, so the hospitals Therefore, the energy efficiency of hospital buildings to improve energy efficiency, with the minimum resources and minimum energy consumption to achieve maximum medical services, can meet the current development needs.
Technical measures to analyze the energy-saving effect of hospital construction
Hospitals belong to the public **** building, and its energy-saving potential is very great. But because of its function and environmental specificity, some commonly used energy saving measures can not be applied to the hospital, especially the more special ` medical room. If improperly applied can also cause adverse consequences. Therefore, it is necessary to analyze the energy saving of targeted hospital building projects. Compared with traditional hospital buildings, the main energy consumption of hospitals currently includes air conditioning, heating systems and lighting. Energy saving should be explored and analyzed from these aspects, but must ensure to meet the normal prevention and control of hospitals, such as infection control, the smooth implementation of medical treatment. Without these, energy saving is also empty talk. In practical terms, it should first meet the medical and health requirements of hospitals, and on this basis, research on energy-saving technologies and measures applicable to hospital construction projects. This article will focus on the energy-saving measures for special departments in hospitals.
Energy saving of the building itself
As the general hospital building area is very large, and many hospitals have adopted a large volume of glass walls and other facilities, resulting in a lot of public **** space energy consumption is unreasonable, for the outpatient clinic complex and other buildings should be in accordance with our country has promulgated the "energy-saving standards for public **** building" (GB 50189-2005) for the design of hospital buildings, through the analysis of some hospital outpatient and emergency building power consumption can be seen, if the heat transfer coefficient of the peripheral building of the hospital can reach the relevant provisions of the standard value, then the hospital's energy consumption of the building can be energy-saving than some of the existing hospitals by about 25%, so for the hospital building in accordance with existing energy-saving norms for the design of the hospital building energy-saving effect can be Substantial increase, so in the design of hospital buildings, should not blindly go after the artistic effect, the energy saving of the building should also be emphasized.
Heating and air conditioning and domestic hot water system
Because hospitals are very demanding for the environment, hospitals have strict requirements for indoor temperature, humidity and dust, so the hospital air conditioning system is very large, coupled with the existing air conditioning system of many hospitals with outdated equipment, power consumption is very large, so the air conditioning system for hospitals is necessary to save energy. Energy saving system is very necessary, can be in the air conditioning chiller operation mode, chiller output water temperature setting, dynamic flow control, condensate recovery and other aspects of the air conditioning system for energy-saving control, according to statistics, the hospital's domestic water system can account for about 20% of the energy consumption of the entire hospital, and at present most hospitals use the boiler room to supply hot water, but the boiler room for the hot water The efficiency of the boiler room for hot water is very low, if the hospital building to use some of the use of solar energy or the use of air exhaust system to set up a heat pump water heater and other use of new energy hot water building design, can be to a large extent, energy-saving control.
Hospital building automation system
For the energy saving of the hospital construction project, should take into full account the hospital automation system, at present, many of China's hospital automation system is not perfect, and even some hospitals do not have an automation system, so that the hospital building cold, heat, light and other systems do not play out completely should have the control function, although some hospitals are in the hospital, but not in the hospital, but the hospital is not in the hospital. Control functions, although some hospitals in the building are installed temperature and light sensors, but practice has shown that these sensors are not up to the design standards, so the energy-saving hospital buildings do not reach the role it should be, so in the energy-saving design and construction of hospital buildings, should be a detailed analysis of the hospital building self-control system and research.
Thinking about improving energy efficiency in hospital construction
Solar energy utilization
Solar energy utilization is an important measure for energy saving in buildings, especially in the treatment of energy saving in hospital construction, which should be simulated using computer software to determine whether the hospital building can meet the minimum sunlight requirement. Whether to meet the minimum sunlight requirements, but also to take into account whether it will have an impact on the buildings around the hospital, if only to do these analyses is not able to judge a hospital building on the use of solar energy is reasonable, but also with reference to the design of the hospital building, from the structure of the hospital building project for the use of solar energy to achieve energy-saving effect, through the practice of surface, if the main facade of the hospital building is facing Through the practice of surface, if the hospital building's main facade is facing the south or slightly to the east, it can greatly improve the utilization rate of solar energy in hospital buildings.
Application of insulation measures
As the difference between indoor and outdoor temperatures in winter and summer is very large, if the hospital's building measures do not take the appropriate insulation measures, the outdoor temperature will balance the hospital's indoor temperature, and hospitals due to its special nature, requiring its stability all year round at a stable level, which will result in increased energy consumption of the air conditioning system in the hospital. This will cause the hospital air conditioning system to increase the energy consumption, and if the design of the hospital construction project, on the wall and the ground and so on to take thermal insulation measures, you can greatly reduce the difference between indoor and outdoor temperatures brought about by the energy consumption.
Selection of windows and doors in hospital buildings
In the hospital building, the selection of windows and doors for hospitals in the energy-saving effect will also have an impact, especially some high-rise buildings or wind speed is very high in the region is very obvious, according to the relevant technical statistics, generally a 20 square meters of the ward, in the summer, will require about 88 w air conditioning refrigeration.
Influence of the shape of the hospital building
In architecture, the change of the shape of the hospital building is to determine the main factors of the hospital building and the contact area of the outside world, and if the greater the coefficient of the shape of the building, the more energy consumed by the building, so in the plan design of the hospital building project, should minimize the design of the bump, so that the hospital building and the outside world of the contact at least, many foreign hospital buildings take the shape of a round tower, which makes the hospital building and the outside world of the least contact. Currently, many foreign hospital buildings take the shape of a round tower, so that the building will have the least contact with the outside world, to achieve the best energy-saving effect, so in the design of the hospital building form, should pay enough attention to the contact area between the hospital building and the outside world, and try to minimize the contact to minimize the effect of the building form on energy consumption.
Conclusion
In the analysis of the measures taken for the energy-saving effect of the hospital construction project, it must be clear that the hospital's public **** nature and the special nature of its functional requirements. Starting from the nature of the hospital construction project, avoiding to follow the traditional concept or not according to the actual situation of the hospital and formulate meaningless energy saving measures. On this basis, the main energy-consuming constructions in hospitals are analyzed and their working principles are understood. Analyze the needs in different situations, and use the scientific and correct way for the selection of energy-saving measures, and ultimately to achieve energy saving effect as well as the further improvement of the effect.
