Self-adaptation control method and device of air conditioner

Abstract

The invention discloses a self-adaptation control method and device of an air conditioner. The method includes setting a mapping relation of outdoor environment temperature and a heating threshold and a refrigeration threshold in advance; obtaining indoor environment temperature and the outdoor environment temperature after the air conditioner is in a self-adaptation operation mode and an environment temperature obtaining command is detected; obtaining the heating threshold and the refrigeration threshold which correspond to the obtained outdoor environment temperature according to the preset mapping relation of the outdoor environment temperature and the heating threshold and the refrigeration threshold; calculating the difference of the indoor environment temperature and target temperature set by a user, comparing the difference with the heating threshold and the refrigeration threshold, confirming a practical operation mode of the air conditioner according to a comparison result, and controlling the air conditioner to operate in the practical operation mode. The method and device enables operation modes of the air conditioner to be dynamically adjusted according to changes of the indoor environment temperature, can accelerates temperature adjustment, and achieves the aim of energy saving and electricity saving.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an adaptive method and device for an air conditioner. Background technique [0002] Present air conditioners generally have cooling mode, heating mode, air supply mode, dehumidification mode and automatic operation mode. The automatic operation mode judges the actual operation mode of the current air conditioner according to the difference between the user's set temperature and the indoor ambient temperature, and this temperature difference is fixed by the air conditioner manufacturer. Such as figure 1 As shown, the current automatic operation mode of the air conditioner, when the indoor temperature is higher than the user's set temperature +1°C, it will always run in cooling mode; when the indoor temperature is lower than the set temperature -1°C, it will always run in heating mode; When the indoor temperature is within ±1°C of the set temperature, the current mode is switched ...

Problems solved by technology

[0003] Because the above method does not consider the influence of outdoor temperature at all, and when the outdoor temperature is relatively low, the cold loss of the indoor temperature will be relatively small, and the cooling effect will be better, but the heat loss will be more, and the heating effect will be relatively poor.

Therefore, when the outdoor temperature is relatively low and the air conditioner is cooling, the cold outdoor air will transmit more cold energy through radiation and door gaps. At this time, if the indoor temperature is still within ±1°C of the set temperature, the cooling mode will Switching to the air supply mode, plus the cooling capacity transmitted by the outdoor air temperature will cause the cooling capacity to be too large, and the indoor ambient temperature will drop too much, which will not only make the user uncomfortable, but also waste unnecessary power
