Frequency conversion air conditioner and condensation prevention control method thereof

Abstract

The invention discloses a frequency conversion air conditioner and a condensation prevention control method thereof. The method comprises the steps of S1, performing refrigeration startup; S2, judgingwhether a compressor continuously runs for first duration or not, and if no, entering in a common refrigeration control mode; S3, if yes, judging whether indoor environment temperature T1 and outdoorenvironment temperature T4 meet the condition that the indoor environment temperature T1 is larger than or equal to 24 DEG C and smaller than or equal to 30 DEG C, and the outdoor environment temperature T4 is larger than or equal to 24 DEG C and smaller than or equal or 30 DEG C or not; S4, if yes, judging whether the rotating speed of an indoor fan is k times smaller than rated rotating speed or not, wherein k is taken from 50 to 60%; and S5, if yes, entering in the condensation prevention control mode, and under the condensation prevention control mode, through comparison of the range of the temperature difference between the dew point temperature and the temperature of an indoor evaporator, adjusting the running frequency of the compressor. Therefore, through judging whether the indoor environment temperature and the outdoor environment temperature are within the preset temperature range or not, and in combination with the rotating speed of fan running, whether the condensation prevention control mode is executed or not is judged, the temperature of the indoor evaporator is made to be higher than the dew point temperature, and the condensation is reduced.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an inverter air conditioner and an anti-condensation control method thereof. Background technique [0002] In the existing frequency conversion air conditioner, the temperature difference between the set temperature and the room temperature and the temperature difference between the upper and lower moments of the room are used to control the change of the frequency during cooling, so as to realize the cooling of the room. When the air conditioner is in the middle wind position and below, the air temperature of the air conditioner is relatively low, and condensation water is likely to be generated, and the dehumidification capacity is too large, which is easy to do useless work and consumes a lot of energy. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present i...
