Hotel cafeteria hoods and other ventilation systems engineering stove

Changsha Ruifeng kitchen equipment design factory is the production of cold hotel fume hood, exhaust pipe professional manufacturers. Convinced that cheap is essential to win customers, so we seek cheaper purchase channels, training of staff attentive personality, sense of responsibility to enhance service employees. Our business model can not be separated from each other introduce customers, so we have to be let in price, reputation, quality, customer satisfaction in all aspects of the kitchen exhaust volume is determined: exhaust volume according to the size of the kitchen, stove number of smoke cover size, distribution of pollutants to determine. Usually there are several ways to determine the amount of exhaust kitchen: (1) by the number of ventilators for air exchange volume: each kitchen vary greatly, the number of kitchen area and utensils, a stove is not proportional to the same generation of pollutants and kitchen heat is also very different. Indeed kitchen ventilation is not complete ventilation, there will be a large error by ACH design air volume. (2) the number of the design according to the amount of exhaust pollutant emissions at: The State Environmental Protection GB18483-2001 restaurants fume emission standards for ventilation quantity required for each burner 2000m3 / h. I believe that this method according to the design air volume is still limited. In fact the actual situation of the catering complex: Stove size, there are wide-style stove, Soviet-style, respectively; in addition to the stove but also have soup pot, earthen pot, steamer oven; in function, there is room for cooking, between cooking, pastry room, grill, between Western and processing, rooms and other dishes, heat emission and pollutant emissions at all different, simply press the number determined stove exhaust volume is inappropriate. (3) to determine the size of the hood air flow: the inlet area and into the wind speeds along the hood and the stove between the product more appropriate to calculate the amount of wind. Exhaust volume can be calculated as: G = 3600L (h2-h1) Vx, the length of the inlet side of the lower m3 / h L ------ HOOD (HOOD both ends of the length and double-sided into the wind on the other side Length should be counted), m; h1 ----- stove height, m; h2 ----- under the hood along the height, m; Vx ------ into the wind speed, m / s . I plant ventilation pipe all the national standards, high quality profiles, and carefully assembled from processing, factory rigorous testing, home installation. Our spirit of "excellence, sincere service" business philosophy and "integrity, professional and efficient" service and dedication to providing excellent products and quality services to new and existing customers, the majority of customer recognition and trust, and In the fierce competition in the market continue to grow and develop. Exhaust smoke pipe - Ventilation pipe design and installation, commissioning and maintenance processing transformation of the system piping.
