Abstract:

The difference between heat supply unit and full condensing unit is analyzed.Advice is provided for cold end optimization.Cold end optimization of the heat supply unit shall consider heating season and non-heating seasons repectively.The influence of backpressure on heat consumption during heating season is less,so the designed backpressure shall be determined based on the climate conditions of non-heating seasons,cold end arrangement and running time of the unit.
