Summary

An air-source heat pump for floor heating system was developed and tested which produced hot water for heating the floor of residential buildings by heat pump cycle. The field test of the air-source heat pump for the floor heating system has been conducted in winter for 93 days. During the test, the compression ratio (π) was controlled stable based on the exergy performance analysis. The theoretical 𝜂𝜂 x of the system decreases with the increase of the compression ratio (π). The values of π were maintained as small as possible from 2 to 6 approximately in the ideal control method in the winter test. Based on the control strategy, the system was proved to be robust. The energy efficiency ratio (EER) ranged from 2.32 to 4.71 while the heat capacity ranged from 3.8 to 10 kW. Especially, the performances of the system in the warmest and coldest days were compared. The results indicate good environmental adaptability of the heat pump system.
