Aerodynamic calculation of the section of air ducts online

Supply and exhaust ventilation should provide: in winter - temperature 16-21°C (air humidity is not standardized), air mobility 0.15 m/s; in summer - the temperature in the main rooms is no more than 3°С (in kitchens 5°С) higher than the calculated outdoor ventilation temperature according to parameters A (air humidity is not standardized), air mobility 0,25 m/s (in kitchens 0,5 m/s).
Air conditioning systems must provide: in winter - temperature 20—21°С, air humidity 45—50%, mobility 0,15 m/s; summer - temperature 23—26°С, humidity 50—55%, mobility 0,25 m/s.

Ordering the design of ventilation and air conditioning You will find independent and professional consultants in the field of thermal power engineering.

Pressure loss in the duct, dP=Pп-Pк(Па) Pressure loss dP and Duct diameter are the input data for the calculation
Air volume L, m3/hour, which passes through the duct Pressure loss dP and Air volume Q are the input data for the calculation
Air velocity v, m/s Pressure loss dP and Velocity V are the input data for the calculation
Pipe diameter or equivalent box diameter, mm Diameter and Air volume Q are the input data for the calculation

Do you want to order an aerodynamic calculation of a ventilation or air conditioning system? or immediately Order ventilation and air conditioning design
To do this, our specialists need the following technical data: for ventilation of the house - floor drawings with tracing of air ducts and the type of room. After receiving these data, we can calculate the cost of aerodynamic calculation of air ducts. Assignments are accepted drawn by hand, then scan and send to e-mail project(@)mathcentre.com.ua marked "calculation of the cross-section of air ducts". Payment is accepted by any means known to you. Lead time 3 business days.
