If the fresh air is sent directly to the room without treatment, it will inevitably increase the energy consumption of the air conditioning systemTo reduce the energy consumption of air conditioning system and save energy, this paper presents that the exhaust heat recovery technology can be applied to the DOAS (Dedicated Outdoor Air System) to recover the energy in the exhaust air.Firstly, this paper presents a novel design of exhaust air heat hump, which combines the return air subcooling and the mixed air condensation technology to improve the COP of the exhaust air heat hump. At the same time, the simulation model of the outdoor air handling unit using exhaust heat hump was established by using GREATLAB simulation software. As the parameters of the components are optimiz...
