RESUMO

The aim of this research is to investigate the energetic performance of two distinct kinds of swimming pool heating systems: gas-fired and electric heat pump. A practical instrumentation research was prepared in these two indoor swimming pools, placed in the same location. Besides these, other four swimming pool, placed each in a different ambient in the city of São Paulo also received the instrumentation so that it will be possible to run future researches, once the data is already being collected by the data loggers installed. As a result of the data analysis, it was found that the average coefficient of performance of the heat pumps studied is 4. For the natural gas fired system, the global efficiency factor was found to be 76%. The efficiency of the heaters isolated was found to be 82%. This research showed that the COP of heat pump systems has strong correlation with the air temperature. The lower the air temperature, the lower the COP. Temperature also has strong influence on the consumption of energy.
