摘要
Abstract
The traditional air source heat pump (ASHP)space cooling system adopts 45℃ outlet water temperature (OWT)and 40℃ inlet water temperature (IWT).Reducing the IWT can enhance the unit efficiency leading to decreasing heat capacity.So adopting small-delta temperature terminal is necessary.Considering the modern building comes equipped with ventilator,the ventilator can support part load so that lower IWT strategy can be used to enhance unit efficiency.The IWT can be reduced to 30℃under the premise of satisfying the indoor thermal load.This kind of system with higher COP and lower power consumption is an energy saving system.The Dymola model is established to verify the experimental results,then conducting the simulation of system energy consumption of actual air conditioning system.关键词
