The company built housing for the men along with their families working there. We were mostly two bedroom homes by using a garage and 6 3 bed room homes. Generally there were 24 homes built to begin. A local contractor involving Rankin was presented the contract to build them. In 1967 the actual sold the homes to staff cleanroom workshop living in the houses for $250.00. Staff had to buy a lot in after you of their choice and pay to buy them relocated to their new location. Sixteen of the families moved their houses to Rankin, 8 i went to Big Water.

Air volume calculation and air duct design of clean and sterile room


1. Air volume calculation of clean and sterile room


Calculating and obtaining the larger and smaller air supply volume of the air-conditioned room, and calculating the larger and smaller air supply volume of the air-conditioning system are the basic work for selecting variable air volume terminal devices, air supply outlets, and air conditioning equipment .


1. Calculation of larger air supply volume and smaller air supply volume of air-conditioned room


(1) Larger air supply in air-conditioned rooms.


In the air-conditioned room, the air volume Vs required to eliminate the residual heat in summer is


Vsu003d3600Qs/1.01ρ(tn-t0)


Where Qs—indoor sensible heat load in summer, kW:


tn is the indoor air temperature, °C;


t0 Supply air temperature in summer, °C;


ρ-air density, kg/m3.






The sensible heat here means that when a certain amount of heat is added or reduced, the temperature of the substance will change without a phase change, that is, when the substance does not undergo chemical change or phase change, the temperature required to increase or decrease The heat is called sensible heat; the load formed by the sensible heat in the air-conditioned room is the sensible heat load.


In addition to calculating the above Vs, it is also necessary to calculate 'the required air volume V's' to eliminate the indoor residual humidity' and 'the required air volume VW to meet the insufficient indoor heat in winter'.


Select a larger amount from Vs, V's' and VW as the larger air volume of the air-conditioned room.


(2) The air supply volume of the air-conditioned room is small.


To calculate the minimum air supply volume of an air-conditioned room (indoor), the following three conditions must first be met:


1) Under the condition of low air supply, the indoor air flow can have a reasonable and uniform distribution.


2) Reasonably control the indoor fresh air volume, because for the variable air volume, the reduction of the supply air volume corresponds to a proportional reduction in the fresh air volume, in order to maintain the hygienic requirements and cleanliness requirements of the air-conditioned room environment (It is reflected in the content of carbon dioxide and other impurity gases that can meet the relevant hygiene standards), and must meet the needs of a small amount of fresh air.


3) To meet the normal humidity requirements of air-conditioned rooms, indoors can provide users with a comfortable living and working environment only under suitable conditions of temperature and humidity.


When the above three conditions are met, the above 'air volume Vs required to eliminate residual heat in summerThe air volume VW required for insufficient heat shall take the smaller value among the three air volumes as the smaller air supply volume in the air-conditioned room. Zhongjing Global Purification can provide consulting, planning, design, construction, installation and transformation of dust-free workshops and sterile rooms and other supporting services.


In general, after meeting the above conditions, the smaller indoor air supply volume should be at least 40% to 50% of the larger air supply volume.


Select and calculate the model and size of the variable air volume terminal device according to the larger and smaller air volume data.






2. Larger and smaller air volume of air conditioning system


In winter, the larger air volume of the variable air volume air conditioning system is determined according to the larger heat load of the system; during summer, the larger air volume of the variable air volume air conditioning system is determined according to the larger cooling load of the system.


The larger air volume of the variable air volume air conditioning system is closely related to factors such as the orientation of the sterile room, the internal use, the service area and the number of rooms, etc. Generally, it can be calculated as 70%-80% of the sum of the maximum air volume of each sterile room .


For comfort air conditioning, the smaller air volume of the system can be calculated as 40%~50% of the larger air volume of the system. When determining the small air volume, the factors and requirements such as the small fresh air volume and the ventilation volume should be taken into account, and the small fresh air volume should be controlled when operating at a small air volume.


2. Air duct design of clean and sterile room


The differences between designing a VAV system air duct and designing a constant air volume system air duct are as follows:


(1) In the sterile room partition, the variable air volume air-conditioning box connected to the main air duct of the winter partition considers the simultaneous use factor. Compared with the constant air volume system, the size of the main air duct is small; the size of the air duct in each partition is determined by the region. Larger air volume is determined.


(2) In order to more effectively adjust the variable air volume terminal device from the actual project, a manual air volume control valve is added at each terminal device to help the initial adjustment.


(3) If a high-speed air supply system is used, circular or elliptical air ducts are generally used to reduce frictional resistance. However, the fan of the high-speed air supply system consumes a lot of energy, and the noise of the pipeline system increases. With the development of the pressure-independent VAVBox basically replacing the pressure-dependent VAVBox and DDC controller, the application of the low-speed air supply system for variable air volume air conditioners is becoming more and more common. Above s, in the European and American style variable air volume system, the measurement accuracy is very low at the wind speed of 5m/ due to the use of the Pitot tube flow sensor. The application and development of Japanese-style variable air volume air conditioning systems that mainly use low-speed air supply systems deserve attention. The energy-saving effect of the variable air volume air conditioning system with low-speed air supply air duct is better than that of the system with high-speed air supply air duct, and the noise of the air duct is also greatly reduced.


The branch air duct of the variable air volume system can use flexible hose, which is easy to install and connect.
