The Application Of Ground Source Heat Pump To Indoor Constant Temperature Swimming Pool Water Heating In The Subtropical Region

With people's awareness of energy conservation and environmental enhancement,ground source heat pump technology has a broad application prospect as a new technology.Ground source heat pump is a kind of green energy saving and environmental protection technology with no pollution,low running cost,low maintenance cost,environment clean.At present,ground source heat pump system in the indoor constant temperature swimming pool is relatively small,and much less in the subtropical region,it was mainly because people lack of comprehensive and systematic understanding on the ground source heat pump technology in indoor constant temperature swimming pool in the application status and problems.Set up the test platform by the use of design and implementation of ground source heating pump system in the indoor constant temperature swimming pool of a research group in the subtropical region.Through the study of the running characteristics,for hot summer and warm winter zone soil source heat pump technology in indoor swimming pool in the application to provide reference and guidance.The main research results are as follows:(1)It has proved through the analyse of the experiment that the use of soil source heat pump technology in the heating pool in subtropical regions can simultaneously satisfy the indoor swimming pool heating,the showers hot water,the winter heating and the summer colding,which can greatly reduce the energy consumption,and the economic benefit,ecological benefit and social benefit are remarkable.So it is suitable for popularization and application.(2)In this experiment,the COP of the unit for heating swimming pool and the system can achieve 4.5 and 3.6,respectively,and the electricity consumption of the system is approximately 30kwh each hour.The COP of the unit and the system can achieve 4.3 and 3.3,respectively,when the air conditioning unit is under the heating operating mode.While the COP of the unit and the system can achieve 4.6 and 3.5,respectively,when the air conditioning unit is under the refrigeration operating mode,and the COP of the unit and the system of the heat pump unit for hot water can achieve 4.9 and 4.2,respectively;(3)The use of soil source heat pump technology in the heating pool,can save 234400 yuan expenses every year,saving rate is around 58.15%,when compared with electric boiler heating and air source heat pump;And it can save 154700 yuan expenses every year,saving rate was 47.83%,compared with oil-fired boiler heating and air source heat pump;it can save 137600 yuan expenses every year,saving rate was 44.91%,compared with gas boiler and air source heat pump system;(4)By using of building energy simulation software eQUEST,simulated the energy consumption of the ground source heating pump system of indoor constant temperature swimming pool in clubs.It can conclud that we should try to reduce the heating temperature and improve the refrigeration temperature setting,to meet the comfort requirements of the premise.
