Air conditioner system, air conditioner and control system

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.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to an air conditioning system, an air conditioner and a control method. Background technique [0002] At present, the main components of conventional household air conditioner indoor units include heat exchangers, fans, wind deflectors, electrical boxes, etc. The adjustment of indoor temperature is mainly done through heat exchange between heat exchangers and indoor air. There will be a strong blowing sensation during the cooling / heating operation; the non-intermittent operation of the movement mechanism such as the fan and the wind deflector makes the noise of the indoor unit louder, and it is difficult to achieve an ideal quiet effect; The air deflector can be used to ensure that the air is as close to the ground as possible. Due to the low density of hot air, it gradually rises to make the room reach the set temperature, but there will be a large temperature gr...

[0002] At present, the main components of conventional household air conditioner indoor units include heat exchangers, fans, wind deflectors, electrical boxes, etc. The adjustment of indoor temperature is mainly done through heat exchange between heat exchangers and indoor air. There will be a strong blowing sensation during the cooling / heating operation; the non-intermittent operation of the movement mechanism such as the fan and the wind deflector makes the noise of the indoor unit louder, and it is difficult to achieve an ideal quiet effect; The air deflector can be used to ensure that the air is as close to the ground as possible. Due to the low density of hot air, it gradually rises to make the room reach the set temperature, but there will be a large temperature gradient in the room, and the relative humidity will decrease, resulting in dryness and poor comfort. The problem

[0003] Patent No. CN200410016770.1 discloses a displacement ventilator, but the configuration of the displacement ventilator is relatively complicated, and the overall assembly is relatively difficult. It is usually used in centralized or semi-centralized cooling / heating systems, and is not suitable for decentralized households. single room cooling / heating applications
