With the development and popularization of solar energy systems, more and more public swimming pools use Solar heating system for swimming pool. Using Solar heating system for swimming pool not only reduces energy costs, but also saves energy and protects the environment. One-time investment in Solar heating system for swimming pool equipment can recover investment costs in 2-4 years. The solar heating system has a life span of 15-20 years, and the fixed income in the later period is obvious.
The design case of heating the public swimming pool by solar energy is for reference.
1. Basic requirements:
Peter is from Oman， wants to heat a 300CBM public swimming pool, use swimming pool at 7:00AM-10:00PM, and when after people swim, they need to provide hot water for a bath. The pool needs to be equipped with a solar heated swimming pool system.
2. Design ideas:
Since Peter is located in Oman, the climate is better.
According to international standards, the temperature requirements of public swimming pools: 26 ~ 28 ° C
①Based on the climate of Oman and the size of the swimming pool, 30 sets of SFB305818 solar collector
②Due to the requirement to use the swimming pool at 7:00AM-10:00PM, and need to provide hot water bath,
It is equipped with a 3000L 2 coil water tank for storing hot water, a bottom coil for the solar collector circulation heating system, and a top coil for hot water supply for people to take a bath.
③It can also achieve the effect of using the swimming pool at any time. When the swimming pool does not reach the desired temperature, the hot water of the water tank can be put into the swimming pool to increase the water temperature.
④And other accessories.
This is a closed pressurized circulation system. When the system is running, the water tank is first heated through the bottom coil. When the water tank reaches a set temperature (for example, 60 ° C), the solar collector starts to heat the swimming pool through the heat exchanger.
Thanks to Peter's need to open the swimming pool at 7:00AM-10:00PM, and need to provide hot water bath.
The system can heat the water tank through the bottom coil and provide hot water to the people through the top coil.
During the open swimming pool time, if the swimming pool does not reach the desired temperature, the hot water in the water tank can be put into the swimming pool to increase the water temperature of the swimming pool. This not only meets the requirements for swimming pools at 7:00AM-10:00PM, it also allows to use the swimming pool at any time.
4.Peter likes the design of this Solar heating system for swimming pool, especially the swimming pool that meets the open swimming pool. It can provide hot water bathing, and beyond his expectations, it can also achieve the effect of using the swimming pool at any time, so that he can give the swimmer provides a satisfactory service.
However, Peter has some doubts about this system:
①Is the water tank insulated?
Yes, we use polyurethane insulation,The thickness of the insulation is 55mm.
②Why use two circulation pumps?
The circulation pump R1 is used for circulation between the collector and the water tank.
The circulation pump R2 is used to circulate between the heat exchanger and the water of the swimming pool.
This is a closed circulation system. The circulating water pump R1 is used to circulate the heating water tank between the collector and the water tank. When the water tank reaches the set temperature (for example, 60 ° C), the valve R4 turns to the heated swimming pool, and the circulating pumps R1 and R2 are simultaneously started. At this time, the circulation pump R1 is used to circulate between the collector and the heat exchanger, and the circulation pump R2 circulates through the heat exchanger and the water of the swimming pool to exchange heat to start heating the swimming pool.
③Will the water in the pipe flow into the pool?
No, the inside of the tube heat exchanger is independent. The water in the pipeline is irrelevant to the water in the swimming pool. The water in the circulating pipeline exchanges heat with the water in the swimming pool, and mixing will never occur.
In the end, he solved Peter's doubts about this Solar heating system for swimming pool. He was very satisfied with the design of the scheme and fundamentally solved his requirements.
This Solar heating system for swimming pool solution is suitable for most public swimming pools, but it still needs to be designed according to the actual situation. The Solar heating system for swimming pool project has many design factors, and the seasonal distribution of sunlight is uneven. The specific configuration plan product details need to be calculated and provided according to the actual size of the pool to avoid unnecessary waste.
