Abstract

The invention relates to an air conditioner control system. A radiant panel is arranged on an indoor unit. The indoor temperature can rapidly reach a set temperature point through the forced convection heat exchange of an indoor unit heat exchanger and air. When the indoor temperature reaches the set temperature, the indoor comfort degree is kept mainly through thermal radiation of a radiation device, an inner draught fan can be controlled to run in an ultra-silence manner or run at a low-wind gear or run in an intermittent manner or to completely stop running, and therefore the problem that the strong air blowing feeling exists during refrigerating running or heating running is solved, and meanwhile the running noise of the draught fan is reduced. The indoor unit discharges air upwards in the refrigerating process, and discharges air downwards in the heating process. Meanwhile, due to the fact that thermal radiation does not need to be spread through media and indoor air doest not have an isolation effect on thermal radiation, thermal radiation directly acts on human bodies and indoor facilities, and uniform indoor temperature gradient and comfort are ensured. Due to the fact that the radiation device bears parts of indoor loads, a radiation heat exchange panel can be produced in a modularized manner, and modularized selection installation of air conditioners is achieved according to sizes of rooms or magnitudes of loads.
