Simulation Study Of Commercial Kitchen Ventilation, Air Conditioning And Heat Environment

With the continuous development of catering industry in our country, commercial kitchen environment is becoming more and more get the attention of people. If did not run good design kitchen ventilation, air conditioning and platoon lampblack system can cause bad effects to the environment inside the kitchen, cooking a lot of remaining heat and wet and CO2. soot and other pollutants is not discharge in time will cause harm to people's comfort and health. Business has a more powerful heat source inside the kitchen at the same time, the indoor temperature is high, while there are strong asymmetric radiation, the operating area under high temperature and thermal radiation of the fire and thermal buoyancy lift under the action of the interference of oil gas, and smoke indoors stranded, directly led to the deterioration of the indoor pollution. An uncomfortable will inevitably lead to the indoor thermal environment are workers work efficiency is reduced, will affect the normal operation of the commercial kitchen, commercial kitchen indoor environment has become an urgent problem in the catering industry.The thermal environment of the modern commercial kitchen control system by single before ventilation system to develop in the multicomponent ventilation air conditioning system. adjust to the kitchen and internal environment ability is stronger. especially for the temperature control effect is more obvious. Based on the present study of commercial kitchen ventilation and air conditioning at home and abroad, this article adopts the numerical simulation method of commercial kitchen the influence factors of thermal comfort in the indoor environment and comparing the influence factors of indoor pollution control, get some on commercial kitchen indoor environment design parameters. These parameters include air supply system parameter (size of tuyere position, supply air temperature, air speed, air supply) and exhaust system parameters (exhaust hood and canopy hood set height, wind speed), these parameters are indeed provides the choice basis for practical engineering design, has a certain theoretical significance and engineering application value. At the same time, this article also focuses on the application of displacement ventilation mode in commercial kitchen, and the characteristics of displacement ventilation, and air supply velocity under different air supply temperature and same the same supply air temperature under different supply air speed comparison, some general conclusions. Computational fluid dynamics analysis method is recognized at home and abroad of the indoor air distribution design and evaluation of the easiest way.CFD commercial software FLUENT, the current is widely applied STAR - CD, PHOENICS, etc., their function more comprehensive, applicability, all kinds of complicated problems in engineering can be solved. The FLUENT software under the AIRPAK software in the field of software is to specialise in HVAC.AIRPAK is a powerful visualization post-processing ability, be able to generate the velocity vector, cloud and particles flow animation, depicting the airflow movement in real time.After the simulation, but also provide a powerful numerical report, thus the room air distribution, thermal comfort and indoor air quality (IAQ) to conduct a comprehensive evaluation...
