香港赛马会六合信息网站 www.baqzj.icu 香港赛马会六合信息网站價格組成由下面幾個因素組成1: 香港赛马会六合信息网站房間大小(房間大小決定風機選型，風機數量，風管大小)通常香港赛马会六合信息网站有軸流風機、離心風機、風柜來制作.軸流風機安裝于香港赛马会六合信息网站頂部，在天花上裝根據風機的數量裝相應的百葉窗口，采用上面出風上面回風的概念，此方法造價低廉，溫度均勻度可控性不高，因為熱氣是從下往上的離心風機安裝于香港赛马会六合信息网站頂部，再根據風機的功率以及房間的大小設計相應的風管數量，每條風管連接至室內底部，在每條風管上安裝2個雙層百葉出風口，出風口可以調節出風的方向。然后再從頂部的回風口出風進行循環。一般房間不是很大的老化房采用離心風機主。
The price composition of the aging house is composed of the following factors: the size of the aging room (room size determines the type of fan, the number of fans, the size of ducts) usually has an axial fan, a centrifugal fan and a wind cabinet to make the aging room. The axial fan is installed on the top of the aging house, and the corresponding shutter window is installed on the ceiling according to the number of fans. The concept of return air above the outflow is adopted. The method has low cost and low controllability of temperature uniformity, because the hot air is installed on the top of the aging room from the bottom to the top of the centrifugal fan, and then according to the power of the fan and the size of the room, the corresponding number of air ducts is designed. Each air duct is connected to the bottom of the room, and two double-layer louver outlets are installed on each air duct. The outlet can adjust the direction of the air outlet. Then the air is circulated from the top return air outlet. Centrifugal fans are used in ageing rooms which are not very large in general.
Windshield is mainly used when the room in the aging room is too big, the span is too wide and the temperature uniformity is too high. If the room is too large, the number of centrifugal fans will increase correspondingly, and the noise will be very large. The cost is very high.
2: Temperature range (different materials used for different temperature range)
At present, the commonly used thermal insulation material on the market is high density rigid polyurethane foam. The exterior is 304 stainless steel. Its maximum temperature resistance is 85 degrees, its hardness is good, and its quality is good. Especially for large-scale aging houses, this material must be used. It is easy to disassemble and assemble, and it is easy to move the aging houses. But the price is relatively expensive, but most professional companies will use it.
In addition, EPS color steel plate is mainly used for aging at room temperature to 60 degrees. EPS color steel plate, commonly known as foam board, is not flame retardant. It does not meet the requirements of grade B2 for classification of combustion properties of building materials. It has no problem in long term usage below 60 degrees. The rock wool color steel plate is used at 60 degrees aging temperature.
3: The products that need to be aged and the power of the products (the difference of the products involves whether the products are heated or not, and the power involves the configuration of the power supply inside).
Power of ageing products: In the ageing room, power should be supplied to the ageing frame of the products. Power involves the size and quantity of wire rods. If the heating of the products involves the use of civil or military wire rods.
4: Temperature Uniformity Requirements
The temperature of the aging room is generally (+1 C) at 40 degrees, (+3 C) at 50 degrees, and (+5 C) above 60 degrees. If the uniformity of above 60 degrees is too high, it can be controlled by PLC or by the way of mother computer.
5: Frequently aging temperature point and total power of products (related to exhaust system, exhaust air is based on the size of the room temperature range and the power of the product to find a constant temperature point, when the product heating is too high, exhaust fan operation guarantees that the temperature is controlled at the set temperature)
Frequent temperature points of aging room: involving exhaust system, according to the total power (heating power) of products in aging room, and then according to the need for a certain temperature, the power of exhaust fan and the size of exhaust duct can be calculated by the corresponding formula. At present, the most advanced technology on the market is hot air circulation technology, which has good temperature uniformity.
