| Summary: | With the increasing attention on humidity problem, Dual Cycle Air Dehumidification system（DCADS）is recommended due to its ability to supply a dry, comfortable working and living environment with a lower cost compared with traditional DOAS. DCADS consists of a AHU system as well as a heat pump system which is made up of 4 main components namely compressor, condenser, expansion and evaporator. In order to solve the indoor cooling and dehumidification problem, this project intends to analyse the working principle of this machine, Simulink 3 parts: cooling coil, evaporator and condenser which directly make the heat transfer with input air in DCADS. Suppose the initial input hot wet air is 35℃ with RH 80%, a suitable set of mass rates of refrigerants is also proposed to be determined during the experiment so as to provide a dry, cool fresh air (aimed to at the state of 15℃/51%) at the outlet. |
