蓄热型太阳能热泵LPG气化系统的模拟研究
Simulation research on the LPG gasification system utilizing regenerative solar assisted heat pump
摘要
Abstract
In order to reduce power consumption and to improve the utilization of renewable energy, a novel LPG vaporization system utilizing regenerative direct-expansion solar assisted heat pump (named as RDX-SAHPV system) has been presented. In this paper, the 14 operating modes of the system are introduced and the mathematical model of each part of the system is established. On the basis of the above, taking a residential area of 1000 inhabitants in Beijing as the gas-supply object, then a numerical simulation of the RDX-SAHPV system is carried out by using Matlab for the gas-supply object. The results show that, compared with the ordinary DX-SAHPV system (without phase change heat storage tank), the operation time of DX-SAHPV system in RDX-SAHPV is increased by 547.5 hours and the auxiliary heat source running time is reduced by 161.7 hours, the total power consumption is reduced by 14%.关键词
