Temperature Prediction and Pressurization Design for Vertical Shaft

​Predict vertical shaft temperature just before a fire starts


* Vertical shaft temperature variable - Weather factors: ambient temperature, wind, sun position - Architectural factors: location of the vertical shaft in the building (center, edge), leakage characteristics of the vertical shaft, insulation characteristics of the building - Thermal factors: outside air entering the building, heating load, cooling load, people, thermo-equipments * Vertical shaft temperature prediction method - Option 1: Using EnergyPlus program, https://blog.naver.com/hbscd/222929116510 - Option 2: Reflect the contents of EN 12101-13 (2022), clause 8.2.2 in the domestic TAB procedure --> Reflect the temperature of buildings of similar use and scale

Prediction of temperature according to pressurization of vertical shaft after fire * Vertical wind temperature variable - Weather factors: outside air temperature, wind, sun position - Architectural factors: location of the vertical shaft in the building (center, edge), leakage characteristics of the vertical shaft, insulation characteristics of the building - Thermal factors: outside air entering the building, heating load, cooling load, people, thermo-equipments - Air supply: supply and (or) exhaust volume flow rate for a specific area * Vertical shaft temperature prediction method - Option 1: According to equation 10.1 from 'Handbook of smoke control engineering', page 231 - Option 2: Using the 'EnergyPlus' program * Supply air volume flow rate calculation method - EN 12101-13(2022) : Supply 2-3 m/s of fresh air in vertical wind direction - Laboratory proposal: cooling/heating of the vertical draft temperature to a temperature that minimizes the grinding effect problem by supply air before the evacuation start time according to the building characteristics - Combining CONTAM and EnergyPlus

CONTAM simulation results of ‘Neutral zone position control type pressure differential system’

이미지
 I conducted a simulation of applying 'Neutral zone position control type pressure differential system' to a tall building in South Korea. 1. Building overview It is a tall building consisting of parking lots (B7F~B1F), commercial facilities(1F~2F), and apartment complexes (3F~43F, 6 households/floor), and has a structure in which one corridor in the center is connected to the 9 vertical shafts. The parking lots on each floor are connected to each other through vehicle ramps. Figure 1 - Basement floor Figure 2 - 3rd floor 2. Overview of 'Neutral zone position control type pressure differential system'    - Installation of 9 dampers connecting each of the 9 vertical shafts and the parking lot on the first basement floor (See Figure 1).    - Installation of 9 dampers connecting each of the 9 vertical shafts and outdoor air on the rooftop. 3. Scenario conditions    - Scenario common conditions (cold weather, dawn): outside temperature -10.4℃, atmospheric ...

Understanding the Stack Effect

  1. Understanding the Stack Effect - Water tank 2. understanding the stack effect - chimneys 3. Understanding the Stack Effect - Architecture - Hydrodynamic building = a structure consisting of several round balloons and long balloons connected to their neighbors by large and small gaps.  - Factors of the stack effect: 1. 2 compartments connected by gaps, having a height, and aligned in parallel, 2. Density difference (air and waㄱter at the same temperature, air at a different temperature)  -Eliminate the stack effect: eliminate the gaps or eliminate the height or eliminate the density difference 4. Definitions of Bouyancy and Stack Effect Definition of Bouyancy - The force by which a fluid overcomes the gravitational pull of an object immersed in that fluid and pushes the object upward.  - Buoyancy = the force caused by the pressure difference on the top surface of an object - the object's gravity  - Pressure difference acting on the top surface of the object ...

Vertical shaft pressure changes due to venting and pressurization

이미지
1. Venting (opening of natural ventilation elements such as exhaust windows): Opening of a vent increases the leakage gap area at the height where it is located. Therefore, it plays a role in pulling the neutral band to the venting position(Refer to the Figure 7.9 of "Smoke Movement and control in High-rise Buildings - George T. Tamura, P.E/1994"). 2. Outside air Supply to the vertical shaft : Pressurization by the supply of outside air moves the vertical shaft pressure line to the right, and the resulting temperature change causes the slope of the pressure line to approximate that of the outside air. The volume flow rate of pressurization and the amount of parallel movement of the vertical shaft pressure line to the right are proportional. #Vertical #shaft #pressure #changes #venting #pressurization
