Embodiment Construction
[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0047] The main technical solution of the embodiment of the present invention is: by obtaining the indoor ambient temperature T1, the indoor unit evaporation temperature Te and the indoor unit coil outlet temperature T2B, according to the indoor ambient temperature T1, the indoor unit evaporation temperature Te and the indoor unit coil outlet temperature T2B Calculate the maximum heat transfer temperature difference Tmax and the minimum heat transfer temperature difference Tmin, obtain the heat transfer effect based on the maximum heat transfer temperature difference Tmax and the minimum heat transfer temperature difference Tmin, and then adjust the operation of the indoor fan according to the obtained heat transfer effect. The present invention can adjust the wind gear of the indoor fan according to the heat exchange ...

The invention discloses a control method for an indoor fan of an air conditioner. The method includes the steps of obtaining the indoor environment temperature T1, the evaporating temperature Te of an indoor unit and the coil pipe outlet temperature T2B of the indoor unit, working out the maximum heat exchange temperature difference Tmax according to the indoor environment temperature T1 and the coil pipe outlet temperature T2B of the indoor unit, working out the minimum heat exchange temperature difference Tmin according to the evaporating temperature Te of the indoor unit and the coil pipe outlet temperature T2B of the indoor unit, working out regulation parameters of the indoor fan of the air conditioner according to the maximum heat exchange temperature difference Tmax and the minimum heat exchange temperature difference Tmin, and regulating operation of the indoor fan according to the regulation parameters. The invention further discloses the air conditioner. The method provides a means to regulate a wind shield of the indoor fan according to heat exchange demands, the degree of intelligence of the indoor fan control mode is increased, and accordingly resource waste is reduced.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor fan control method and an air conditioner. Background technique [0002] At present, during the operation of the heat pump air conditioner, the outdoor unit consumes most of the energy. Compared with the outdoor unit, the indoor unit of the heat pump air conditioner consumes relatively less energy. In order to meet the heat exchange demand, the fan operation of the indoor unit will have a large margin. The fixed control method adopted for the windshield of the fan does not adjust the windshield of the fan according to the actual heat exchange demand, or adjusts the windshield of the fan manually. Therefore, during the operation of the existing indoor fan, the wind gear cannot be automatically adjusted according to the heat exchange requirement, resulting in poor intelligence in the control mode of the indoor fan and waste of resources.
