Analysis of novel multi-function heat-pump system applicable to indoor swimming pool space

In traditional way, the return air of the indoor swimming pool space with high temperature and humidity is usually discharged directly, which resulted in the energy dissipation to some degree. This paper introduced a novel multi-function heat-pump system applicable to the indoor swimming pool space. This system can recover the latent heat from the return air of the indoor swimming pool space with the compression heat-pump system. The recovered energy is used to heat the fresh air and replenished water. Furthermore, through the switching among three condensers in the system, the air conditioning and humidity controlling of the air indoor can be achieved. Technical and economic analysis was performed in the paper. The results showed that: The novel heat-pump system can save energy considerably. The operating costs decreased significantly. The amount of equipments in air conditioning and heating will be decreased also, and it will avoid environmental pollution generated by the combustion of traditional boiler fuel.
