The determinants of the cost of the aging room; the common temperature points of the aging room: involving the exhaust system, according to the total power (heating power) of the products in the aging room, and then according to the required temperature, the power of the exhaust fan and the size of the 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. The price composition of aging house is composed of the following factors
1: Room size (room size determines fan selection, number of fans, duct size)
Usually there are axial flow fans, centrifugal fans and air cupboards on the market.
Axial flow fan is installed on the top of aging house, and the corresponding shutter window is installed on ceiling according to the number of fans. The concept of return air above the top outlet is adopted. This method is cheap and the temperature uniformity is not controllable because the hot air is from the bottom to the top.
The centrifugal fan is installed on the top of the aging room, and then the corresponding number of air ducts is designed according to the power of the fan and the size of the room. Each air duct is connected to the bottom of the room. 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)
