Abstract The stability of temperature inside the pigeonhouse directly affects the egg production rate of breeding pigeons and the growth quality of meat pigeons. In order to maintain a stable hot and humid environment in the pigeonhouse, two air conditioning schemes were proposed. The difference in supply and return water temperature and energy efficiency of the two schemes were compared, and the scheme with strong energy-saving performance was prioritized. Using the Transient System Simulation Program simulation method, two simulation models were built for the two schemes, and the water temperature difference and energy efficiency of the air conditioning supply and return during the refrigeration season were compared and analyzed. The average temperature difference between supply and return water in Scheme I(3.92 ℃)is higher than Scheme I(1.67 ℃)， with a heat pump energy-saving rate of 11.6% and a water system energy-saving rate of 30.05%. Scheme II has better energy-saving performancethan Scheme I.Scheme Ⅱ is suggested to be used as the environmental regulation plan for this pigeonhouse.
