Abstract: With the popularity of air-conditioning products, people have higher and higher requirements for the comfort of air-conditioning products, among which air-conditioning condensation has become one of the problems that people focus on and need to solve. The influence of different parameters on condensation is analyzed through the experimental study of the variable frequency wall-mounted machine under different humidity, different wind swing angles and different compressor frequencies. The results show that the frequency converter can effectively solve the condensation problem by reducing the compressor frequency under low humidity, and the angle of the air plate not only affects the temperature of the outlet air, but also affects the flow field characteristics of the outlet, thereby affecting the generation of condensation. In a high humidity environment, it is necessary to comprehensively adjust various parameters to achieve the optimal anti-condensation effect.
