Study on Influence of Altitude on Indoor Temperature Distribution of a Heating Room

The low-temperature air source heat pump (LASHP) has a promising application future in Western Sichuan, while seldom literature focused on the influence of altitude on indoor temperature. Therefore, the influence of altitude on the indoor temperature distribution for space heating was numerically studied and the influence mechanism was discussed in this paper. The results showed that with the increase of altitude, the indoor average temperature would increase and the temperature distribution could be more uniform in horizontal section. The rising range of the warm air was narrower, and the velocity was slower in vertical section. The temperature stratification in high-altitude areas was not as obvious in low-altitude areas; the difference mechanism was that the heat flow driving force decreased as the altitude increased. It was suggested that the air supply velocity should be reduced appropriately in Western Sichuan. The conclusions could provide a useful reference for the application of LASHP in cold plateau areas.
