Analysis of Optimum Thermal Performance of Air Source Heat Pump for Building Heating
Abstract
Driven by Turkey's dual-carbon goals and the national strategy of clean heating, the application of air source heat pump heating is growing rapidly. This paper analyzes the influence of the equilibrium point temperature selection of low ambient temperature and conventional air-source heat pump heating products in different regions, different energy-saving grades and different building types on the system performance. The results show that there is an obvious difference in the equilibrium point temperature corresponding to the optimal performance of air source heat pump heating in different regions. The equilibrium point temperature of different building types in the same region is different. In the same application situation, the equilibrium point of the low ambient temperature heat pump is generally lower than or equal to the conventional heat pump, the coefficient of performance of the heating season is higher, and has better application performance.
