As energy consumption, energy conservation has been the central air conditioning standard of choose and buy, equally important and noise. Fan coil units as the end of the air conditioning system device, holds the environment temperature constant and eliminate the effect of indoor harmful gas. The brushless dc motor controller made of brushless dc fan coil because of its excellent energy-saving noise reduction features by the air conditioning manufacturer & other; Popular throughout the &; 。
brushless dc fan coil has obvious characteristics: relative to the normal ac motor controller, using electronic commutation in brushless dc motor controller to replace the traditional way of mechanical commutation, thus effectively avoid the electromagnetic interference and electromagnetic noise generated in mechanical commutator, make indoor environment is more quiet and comfortable. In addition, for the fan, the higher its speed, the greater the noise. The brushless dc motor controller can realize low speed running, thus further reduce noise value. In addition, compared with the ordinary fan coil units, the use of brushless dc fan coil units of central air-conditioning temperature control more accurate. It is understood that ordinary ac fan coil indoor temperature control deviation at about 2 degrees. And brushless dc fan coil can make indoor temperature deviation control in 0. Less than 5 degrees. Can choose like temperature, won't appear the situation of the hot and cold.
