摘要

目前新风热回收系统的能量回收率在50%-60%

夏季新风送入温度高于室内

冬季新风送入温度低于室内

干扰室内热环境的稳定性。为此

提出一种将转轮与热泵相结合的复合型新风热回收系统

并对该系统夏季工况下的基本性能进行测试。结果表明:与转轮单独运行模式相比

转轮与热泵联合运行模式下

室内排风与室外新风经转轮热交换后

冷凝器冷凝负荷降低

压缩机能耗减小

新风经转轮冷回收后

新风负荷大大降低

节能效益显著

并能有效降低新风送入温度

达到送风设计要求。两种运行模式下新风送风湿度与室内湿度相差都不大

对于室内湿度要求不高的空调房间来说

两种运行模式都具有可靠性;复合型新风热回收系统热回收能量与设备能耗之比较单独的转轮热回收系统要高

且受室内排风温湿度影响较小

具有很大的节能效益。

Abstract

Currently

the energy recovery rate of fresh air heat recovery system is about 50%-60%.The summer fresh air temperature is higher than indoor

winter fresh air temperature is lower than indoor

which disturb the stability of the indoor thermal environment.This paper proposes a new compound air heat recovery system whch combine wheel with heat pump

and test the basic properties of the summer working conditions of the system.Results show that compared with the wheel separate operation mode

in the wheel with heat pump operation mode

after the indoor ventilation and fresh air exchanging heat in the wheel

condenser cooling load is reduced

the compressor power consumption is reduced

fresh air load is greatly reduced after wheel cold recycling

energy saving effect is remarkable

and can effectively decrease the temperature of fresh air

to achieve the design requirements.The difference of fresh air humidity and indoor humidity is not large in the two kinds of operation mode

to air conditioning rooms which have low requirements for indoor humidity

the two operation modes are reliability;the proportion of heat recovery energy and equipment energy consumption in compound air heat recovery system is higher than single wheel heat recovery system

and less affected by the indoor exhaust air temperature and humidity

which has a lot of energy saving efficiency.
