Energy consumption characteristics of exhaust air heat recovery units based on outdoor meteorological parameters

Presents a related analysing method. Considers its energy consumption in calculating the energy savings of the heat recovery unit, and obtains the local minimum enthalpy or temperature under different recycling modes. Taking a library in Shanghai for example, based on typical all-year meteorological parameters, calculates the hourly energy recovery amount and power consumption and obtains the optimal recycling modes and working modes for the heat recovery units through comparison, providing calculation reference for optimal design of HVAC systems.
