Pool Heat Pump-Application

Here are also two types of commercial swimming pools: outdoor commercial swimming pools and indoor heated commercial swimming pools. Generally, indoor commercial swimming pools are smaller and have lower heat loss. In engineering applications, for energy conservation considerations, outdoor commercial swimming pool heat pump generally do not operate throughout the year. When the ambient temperature is low at a certain level, people feel quite uncomfortable even if the water temperature of the swimming pool is maintained at 26~28℃.
Therefore, the heating design and calculation are relatively monotonous. To supplement the heat dissipation on the surface of the pool water and the choice of unit power, the user first determines the use conditions, and the air temperature in this range is suitable for the work of the pool heat pump, and the unit can get better results. The easiest way is to directly estimate The first heating time of the commercial swimming pool, which means the time for the cold water to heat up to 26°C after entering the pool, is generally controlled to be 20-50h.

The climate varies greatly from place to place. Even in the same city, conditions such as wind speed, air temperature, humidity, and light may vary due to various reasons. Therefore, it is very difficult to accurately calculate the heat dissipation on the surface of the outdoor commercial swimming pool. From engineering experience, the heat loss per square meter of swimming pool surface in an open environment is generally 250~500W, which can be used to calculate the pool heat pump specifications for maintaining the water temperature.
Take a commercial swimming pool with a surface area of 2000㎡ as an example, assuming the tap water temperature is 16°C, the average air dry bulb temperature is 20°C, and the temperature difference when heated to 26°C is 10°C, the total heat required is: Q=2000X10kcal
The maximum heating efficiency of the INVERBOOST commercial air source pool heat pump is COP=5.6, and the heating is designed to be completed in 30h (the heat loss during heating is not included), then the total input power of the group of heat pumps is N=20000000/(30X860X5.6)=138.43kw
Because the heat dissipation of the heating process is not calculated, the power selection of the model should be slightly larger than this power.

For open-air commercial swimming pools that are not developed throughout the year, it is easier to choose the Pool Heat Pump model based on the heating time for the first swim. In consideration of reducing the cost of the system, the general time should not be too short.
Indoor commercial swimming pools are mostly developed throughout the year, and their heat dissipation is related to many factors. In addition to considering the heat dissipation load on the water surface, the “humidity dissipation” load of the swimming pool must also be considered, which requires more accurate calculations.
