Winter outdoor pool heating how to calculate the energy consumption

Swimming pool outdoor open-air swimming pool and indoor heated pool two categories. From the nature of the use of swimming pool, swimming pool, training pool, diving pool, children play pool, etc .; from the nature of the business, there are public swimming pool, commercial hotel swimming pool, there are private villas and other residential swimming pool. However, no matter what kind of swimming pool, there is a requirement to maintain the constant temperature of the water, and the temperature of the water varies with the nature of the use. Swimming pool heat loss in the following areas: (1) pool water due to evaporation, surface conduction, pool bottom and wall conduction and continue to lose heat. (2) As people swim in the swimming pool, a portion of the pool of water will be lost and the heat must be constantly replenished. The supplementary water needs heating and some heat needs to be supplemented. (3) In addition, the entire pool water treatment equipment and pipelines are continuously moving towards the surrounding environment Discharge heat. Some of these losses of heat, we need to continue to supplement, in order to maintain a certain temperature of water. These heat losses, combined with the heat loads of swimming pools and showers, can be referred to as recurrent heat loads. In addition, there is also a one-time water temperature pool replacement of all new requirements. In order to clean, disinfection requirements, in a certain period of time, all the water required to empty the pool, re-enter the warm water. If the supplementary water is cold water (water temperature at 5-15 ℃), then the heat required to heat the entire pool of water is a one-time impact load. 1. Swimming pool water temperature Indoor swimming pool water temperature of 24-29 ℃, outdoor is 22-30 ℃. If the indoor swimming pool has a perfect air-conditioning heating facilities, can be taken as 25 ℃; if the temperature is low, can be taken as 27 ℃. The heat loss is related to the temperature of the water in the pool and also to the ambient temperature. General indoor temperature is higher than the water temperature of 1-2 ℃. Ke Lan Water information show that: the best indoor swimming pool environmental parameters: air temperature 26-30 ℃ water temperature 25-28 ℃ ground temperature 30-32 ℃ wind speed 0.05-0.1m / s relative humidity 50-60% 2. indoor swimming Museum relative humidity to maintain a certain indoor swimming pool relative humidity is necessary. When the outdoor temperature is -10 ℃, relative humidity of indoor air is 50-60% and the heat transfer coefficient of double glazing is 2.9W / m2, the glass window will still be damp and dew; even if the outdoor temperature is -1 ℃ , The room is 28 ℃, it will dew. Therefore, swimming pool venues must be dehumidified.
