| Abstract: | The performance of the unit with constant temperature and humidity is analyzed. According to the requirements of the temperature and the relative humidity in the environment, the function of the hot gas defrosting was added in the refrigeration system, the direct surface evaporator suiting the frosting condition was designed and the vapor-liquid separator used to store the liquid during frosting was adopted. The common control system was also adjusted to suit this system. The experimental results show that the design revised can meet the requirements of the application. |
