Abstract


Background. Removal of a large amount of moisture entering the premises as a result of the evaporation, and temperature and humidity maintenance in the room of the pool is the main problem, which should effectively address heat pump air handling system.

Objective. Objective is the thermodynamic analysis of heat pump air conditioning scheme for the indoor pool on a hot period of the year depending on the parameters of the system and the outside air. The scheme provides for the mixing chamber mounting before, and then after the heat pump.

Methods. The mathematical model of heat pump air conditioning system was built, implementation of which was conducted by numerical method of successive approximations.

Results. The scheme from mixing chamber to the heat pump is characterized by relatively low values of the scheme performance coefficient, due to the relatively high heat load of the heat pump evaporator; the increase of the recycling rate and a significant decrease in the proportion of fresh supply air contributes to the preservation of cold air in the system and increases the coefficient of the entire heat pump air scheme.

Conclusions. Pool heat pump air conditioning system with the recirculation of exhaust air and the mixing chamber after the heat pump in warm or hot season has the highest thermodynamic efficiency by the values of the coefficient of the whole circuit, and the working range of changes in temperature and relative humidity of the outside air.
