And below; (2) Building area: 1 10,000 ~ 30,000 square meters
; (3) Building area: 30,000 square meters
Above. The power supply level can be divided into four levels according to the subordinate level of hospital buildings: (1) provincial hospitals; (2) City and prefecture-level hospitals; (3) county hospitals; (4) Township hospitals.
The electrical part of "National Technical Measures for Civil Building Engineering Design" points out that the hospital electricity load index is 40 ~ 70W/m2.
, the lighting power density value pointed out in the building lighting design standard is about 12w/m2.
The above indicators are determined by hospitals at county (district) level and above, and the electricity load index is relatively low. Hospitals usually consist of three parts: outpatient department, medical technology department and inpatient department. The power load of outpatient department and medical technology department is mainly daily load, while that of inpatient department is mainly night load.
The factors that affect the power load mainly include the standards of lighting, air conditioning, water pumps, elevators, ventilators and the configuration of medical equipment. Only by being familiar with the configuration of medical equipment, the estimation of electrical capacity of medical equipment and the reasonable selection of calculation coefficient can we meet the requirements of electricity load in specific places. For the special air conditioner for clean operating room, it usually does not belong to the drawing scope of the design institute, and only reserves the capacity, but the data of different manufacturers are quite different, and it is generally adjusted in the later stage. Due to the rapid development of medical needs, sufficient power consumption margin should be left.
The power load of hospitals is different from residential buildings, and it should be related to the level and category of hospitals, such as tertiary hospitals or specialized hospitals (with different medical equipment), and has little to do with the city and region where the hospitals are located. Therefore, the load should be calculated according to the use function (outpatient service, hospitalization and examination).
Different hospital scale standards, different energy sources (such as air conditioning energy sources) and different power consumption loads. At present, the planned electricity consumption in Beijing is 80VA/m2.
, suitable for general hospital engineering. However, after the new Code for Architectural Design of General Hospitals was issued, the standby power supply capacity (power consumption of hospital logistics support system) increased greatly, and the power consumption index also increased accordingly.
