摘要
Abstract
The winter temperature in the northern regions of China is relatively low,and the heating efficiency of traditional air source systems is low,and it cannot operate normally in severe cold weather.So it is proposed to use trans-critical CO2 air source heat pumps for winter heating and summer cooling in severe cold areas.The change of ambient temperature has a great impact on the performance of the trans-critical CO2 air source heat pump system.In order to study the operating characteristics of the trans-critical CO2 air source heat pump system in cold regions,TRNSYS simulation software is used to test and analyze key parameters such as indoor and outdoor temperature,water supply and return temperature,COP and so on.The results show that there is a large difference between the average supply and return water temperature affected by outdoor environmental temperature in the early and middle heating period.However,there is little fluctuation in the hourly supply and return water temperatures during the heating and cooling periods,indicating that the trans-critical CO2 air source heat pump system has fairly good heating and cooling effects when applied in severe cold regions.关键词
