Experimental Investigation on Heating Performance of Under-floor Heating System based on Vapor-injection Compressor
摘要
Abstract
The scroll compression with vapor injection is applied to under⁃floor heating system to solve the problems of poor heating per⁃formance and instability operation under the condition of low ambient temperature in this paper. The compressor discharge temperature, heating performance, power consumption and COP( Coefficient of Performance) are researched and compared with the heating system with⁃out vapor injection. The results show that under the ambient temperatures between -20℃ and 7℃, the under⁃floor heating system based on vapor⁃injection compressor has a higher heating capacity and COP compared with the normal heating pump , and the heating capacity is increased by 26. 2%, and the COP is increased by 8. 7% on average, and power consumption is only increased by 16% on average;and when the ambient temperature is -20 ℃,the discharge temperature is decreased 12 ℃. The experimental results demonstrate that the un⁃der⁃floor heating system based on vapor⁃injection compressor can better satisfy the demands of low ambient temperature with low energy consumption.关键词
