Analysis on different terminal forms of household air-source heat pump heating systems

Conducts a 60-day performance test for nine typical cases of household air-source heat pump heating systems in Beijing rural area which were reformed in 2016. The terminal forms of nine typical cases include the outdated radiator, the new radiator and the floor radiant coil. During the test period, the indoor mean daily temperatures of these cases are between 16.0 ℃ and 22.1 ℃ and the system COPs are between 2.05 and 2.79. Compares the economical efficiency of the typical cases with different terminal forms by test data. The results show that the annual cost of the outdated radiator, the new radiator and the floor radiant coil are 24.17, 21.11, 17.00 yuan/m2, respectively.
