Mobile terminal, air conditioner and control method thereof and air conditioning system and control method thereof

The invention provides a mobile terminal, an air conditioner and a control method thereof and an air conditioning system and a control method thereof. The air conditioner control method includes: the air conditioner receiving first indoor environment temperature and first indoor environment humidity detected through the mobile terminal; the air conditioner detecting the indoor environment temperature and humidity to acquire second indoor environment temperature and second indoor environment humidity; the air conditioner controlling corresponding loads according to the first indoor environment temperature and the second indoor environment humidity as well as the second indoor environment temperature and the second indoor environment humidity. By the air conditioner, the air conditioner and the control method thereof and the air conditioning system and the control method thereof, overall consideration is given to the temperature and the humidity respectively collected by the air conditioner and the mobile terminal to have the air conditioner controlled, so the deviation brought by uneven indoor temperature field and humidity field can be avoided, body feeling and use comfortableness of the air conditioner are improved, and cooling and heating effects of the air conditioner are improved.
