Performance Parameters Simulation and Optimization Design of Liquid Circulating Heat Recovery System
In order to reduce the energy consumption of clean room fresh air air-conditioning system,based on a Shenzhen biomedical clean workshop liquid circulation heat recycling system,used efficiency-number of heat transfer unit method to establish coil mathematical model,simulated system performance parameters,and designed orthogonal test analysis factors of primary and secondary and optimal scheme,finally,a measure to strengthen the heat exchange is proposed.The results show that when the water flow is 2.5kg/s,the coil heat exchange reaches the peak.Outdoor temperature and humidity increase,the maximum heat recovery increased by 88％,indoor temperature and humidity increase,the maximum heat recovery decreased by 14％.The orthogonal test results show that the main factors affecting heat recovery are water flow,outdoor temperature,indoor temperature,indoor relative humidity,indoor relative humidity.The optimal scheme is water flow is 3.5kg/s,indoor temperature is 24 ℃,and indoor relative humidity is 50％.The overall energy saving of the system is 20kW.
