A control method of a down-flow air conditioner and a down-flow air conditioner

Abstract

The present invention relates to the technical field of air conditioners, and provides a control method for a down-flow air conditioner and a down-flow air conditioner. The control method includes the following steps: calculating an actual near-ground temperature difference and a coil temperature according to a set temperature, a near-ground temperature and an indoor temperature. According to the ratio of the actual near-ground temperature difference to the coil temperature, the corresponding number of light-emitting bulbs are controlled for heating; wherein, the ratio of the near-ground temperature difference to the coil temperature is positively correlated with the number of light-emitting light bulbs controlled by the heater control module. In the control method of the down-flow air conditioner provided by the present invention, the near-ground temperature and the coil temperature are respectively detected by the warm air temperature sensor and the coil temperature sensor, and the actual near-ground temperature and the coil temperature are obtained according to the set temperature of the room, the near-ground temperature and the coil temperature. The ratio of the ground temperature difference to the coil temperature is used to control the corresponding number of light bulbs for heating, which improves the indoor air quality and solves the problem that the temperature at the bottom of the room is too low when the cabinet air conditioner is heated in winter.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and in particular, to a control method of a bottom air conditioner and a bottom air conditioner. Background technique [0002] With the improvement of people's living standards, air conditioners have become a must-use electrical appliance for modern people's homes and offices, especially in summer and winter, air conditioners are used for a long time. The air conditioner can cool in summer and heat in winter, and can adjust the indoor temperature to be warm in winter and cool in summer, providing users with a comfortable environment. [0003] At present, most air conditioners have various modes such as cooling and heating. During the process of automatic control mode, they can automatically select cooling or heating according to the outdoor ambient temperature, and can automatically set the target temperature and temperature according to the indoor and outdoor temperatures. Fan speed, i...
