首发时间:2017-05-25
摘要:螺杆式双级冷凝器空气源热泵供暖系统是一种新型的供热方式,它由两台喷气增焓螺杆式压缩空气源热泵机组串联构成,其凭借高效节能、减排环保的性能优势,尤其适用于锅炉改造后的供暖系统。本文通过TRANSYS软件对某建筑的螺杆式双级冷凝器空气源热泵供暖系统进行模型的建立,将模拟所得数据与实测数据进行比较,验证模型达到很好的仿真效果。在此基础上,比较该系统和传统空气源热泵并联供暖系统的运行特性,分析可知螺杆式双级冷凝器空气源热泵供暖系统的运行特性更佳。

Study On Screw Two-Stage Condenser Performance Air Source Heat Pump Heating System
Abstract:Screw two-stage condenser performance air source heat pump heating system is a new type of heating. It is comprised of two screw compressor air source heat pump with EVI (Enhanced Vapor Injection). It apply to reform boiler heating system. By building simulation model in TRNSYS software, it comparise of the simulated data and measured data. It verity the simulation effect of the simulation model. Based on simulation model, the article compared the new system and conwentional air source heat pump heating system. According to the analysis of their operation characteristics, screw two-stage condenser performance air source heat pump heating system is the better.
Keywords: Gas for heating and air conditioning engineering Screw two-stage condenser performance air source heat pump heating system TRNSYS software coefficient of performance (COP)
