Six determinants of the price of the aging house: the common temperature point of the aging house: involving the exhaust system, according to the total power (heating power) of the products in the aging room, and then according to the need for a very fixed temperature, the power of the exhaust fan and the size of the exhaust duct are calculated by the corresponding formula. 1: Room size of aging room (room size determines fan selection, number of fans, size of ducts) 通常市面有轴流风机、离心风机、风柜来制作
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.
The main reason is that the rooms of aging rooms are too big, the span is too wide, and the temperature uniformity is too high. If the rooms are 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)
Usually there are two kinds of materials for aging room: EPS color steel plate and rock wool color steel plate.
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 of building materials combustion performance classification. It has no problem in long term usage below 60 degrees.
Rockwool coloured steel sheet is flame retardant at ageing temperature above 60 degrees, which meets the requirements of Class A of Combustion Performance Classification of Building Materials.
In addition, there is also a polyurethane color steel plate on the market, its maximum temperature resistance is 85 degrees, flammable, if burned, there are harmful gases generated, only professional companies use this material, and the cost is expensive.
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 ageing room is generally 40 degrees, 1 degree, 50 degree, 3 degree and 60 degree.
If the uniformity of above 60 C is too high, it can be controlled by PLC or by the way of parent 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)
Second: The Practice of Aging Housing
The first one is to use gypsum board to separate a room with a winter heating device or other heating device in the north-east side of the family, and then install several fans on the top or on the wall. This kind of aging house has low cost and low safety factor, which is mainly reflected in the local overheating caused by temperature.
Second: according to the temperature difference, use different heat insulation boards (mainly foam board and rock wool board) to separate a room, then install the corresponding axial fan or cylinder fan on the top according to the size of the room, and then install the corresponding wind pipe. The concept of top blowing and top return air is adopted. The cost of the aging house is slightly higher than that of the first type, but contrary to the principle of hot air. And if the room is a little bigger, the noise is very big and the evenness is not high.
Third: according to the temperature difference, use different insulation boards (mainly foam board, rock wool board) and different thickness of the board to separate a room. Then according to the uniformity of the temperature, the load of the aging product, the size of the room, choose the appropriate size of the fan, the production of the wind pipe, and customize the heating pipe. According to the size and uniformity of the room, PLC is used to control multiple temperature points. The cost of this aging room is relatively high, which requires technical strength and experience. This aging room has a high safety factor.
Fourth kind: burning machine room, isolation room, people do not have to go into the room unloading products, this cost is expensive.
