3, fan coil to send, return air way
Send or return air that is composed of the so-called air flow structure, its legal or not directly affect the air-conditioned room temperature field, the speed field of the average and stability, that is, air conditioning effect is good or bad. The legal structure of the air flow to a certain speed, to avoid air short circuit to ensure a certain length of the jet. Wind speed depends on the static pressure outside the machine, air volume, air outlet and other ingredients. The static pressure is too low, will lead to low air volume, low range, the room hot and cold uneven, planning air flow structure and the actual operating state in the curve there is a big difference, it should be based on the actual structure of the structure, Depth, height, etc., to determine the mid-range air volume, wind speed to determine the appropriate fan coil model. At present, the fan coil on the market, the manufacturers of the machine outside the static pressure is not uniform calibration, the difference is large, plus some of the site is used in the horizontal implanking unit, external short duct, filter, Grille resistance value is large, is in the actual order to determine the external static pressure value selected as 30Pa, and some rooms even determine the 50Pa outside the static pressure value of the unit, greater than the conventional 20Pa next resistance value, so in the actual operation In the guarantee of a good average field, to achieve the expected effect of withered.
4, fan coil should consider other factors
A. Noise control of the purpose of 40dB below the noise on the fan coil, install the muffler processing device, the resistance value of not more than 10Pa.
B. Installation, construction of the character to the stability of insulation quality, condensate discharge, slope, pipe comment debate, the system clean.
C. Water system settings method Horizontal system or vertical system, part of the site selection of vertical systems, can better guarantee the discharge of condensate, to ensure the high level of the room begging.
