Abstract

The new latent heat recovery type semiconductor heat pump ground fast dryer is a kind of integrated semiconductor refrigeration module on the traditional dryer. We simulated the process of the wind being heated by the hot end of the semiconductor refrigeration module under different working conditions through ANSYS software, so as to obtain the best solution for the semiconductor refrigeration module. Using the principles of drying and air condensation, we calculated the influence of the drying rate, drying time, and the condensation effect of the cold end when the air at different hot end inlet wind speeds, ambient temperature and moisture content blows the same amount of moisture on the ground. Through energy-saving analysis, our design saves about 60% energy compared with traditional electric heating style hair dryers. In the case of the same input power, the outlet air temperature of the semiconductor heat pump ground rapid dryer is significantly higher than that of the electric heating hair dryer. Therefore, when the ground is dry with the same amount of moisture, the use of the new semiconductor heat pump ground rapid dryer can significantly shorten drying time, the best drying time shortening rate is as high as 70%.

In our lives, we often see a lot of residual water on the floor that has just been cleaned[1]
9A), within the studied wind speed range, the energy saving efficiency decreases with the increase of the hot end inlet wind speed, and the energy saving efficiency is
Our semiconductor heat pump ground fast dryer utilizes its cold end to absorb the latent heat of condensation of moist air and transfer the heat to the hot end, thereby reducing the amount of electricity provided by the outside world, achieving the purpose of energy saving

Summary

Introduction

We often see a lot of residual water on the floor that has just been cleaned[1]. In hotels and even at home, hair dryers are used to quickly dry carpets on the ground. Because the blown air is at a normal temperature, the temperature is relatively low, which seriously affects the drying rate and drying efficiency. Some parts of the domestic market use electric heating hair dryers. In other areas of drying technology, an energysaving technology that uses latent heat to optimize the drying effect has emerged. It speeds up the evaporation rate of water and greatly shortens the time required for drying. It improves the discomfort caused by wind blowing on pedestrians[7]
