The filtration pump system accounts for up to 70% of a pool's electricity consumption. The pool's filtration pump accounts for the majority of this electricity consumption. It runs frequently and for long periods. Whether renovating or building a public or private pool, optimizing the pump system is a crucial issue for improving efficiency and saving energy. The use of pool flowmeters and variable speed drives enables precise monitoring and control of water flow, ensuring optimal system operation. By maintaining the correct flow rate, energy consumption can be significantly reduced, resulting in lower operating costs and a more environmentally-friendly pool.
Summarize this article with :
A pool filtration pump is responsible for circulating and filtering the water in your pool.
It helps remove dirt, debris and other pollutants from the water. It's an indispensable tool, but one that requires a lot of energy.
The power of the electric pump must be adapted to the volume and flow rate of the water. It's important to choose the right filtration pump for the size of your pool.
For your pool to be perfectly maintained, the flow rate and water renewal must be correct.
The speed of pumps in closed pool systems is regulated by DIN 19643, which also prescribes the volume flow rate and circulation of bathing water required to maintain adequate hygiene standards.
Running time and pump power directly determine power consumption.
Operating time is set according to water temperature.
Pump power is adapted to the volume of water in your pond. The pump is generally sized to filter 25% of the pond per hour.
Regulations stipulate that for each bather, 30 liters of water must be replaced by fresh drinking water per day. However, to guarantee sanitary conditions (bacteria levels, pH balance, chlorine by-products), pool operators traditionally renew more than 120 liters per person.
In order to optimize the pump's power to the pool's actual filtration requirements, the pump should be fitted with a variable speed drive. This makes it possible to filter longer at a lower speed, thus reducing energy consumption. The pump speed can be varied according to the use of the swimming area and the number of people per pool.
New intelligent systems can be set up to use IOT-connected sensors to monitor the presence of bathers and adjust water renewal according to pool occupancy. This advanced energy management systemoptimizes water flow rates in real time, saving water and reducing costs.
Several factors influence the flow rate of a pool pump. The length and diameter of the pipes, the distance between the pump and the pool, the position of the pump in relation to the water level, the size and condition of the filter, and other aquatic or heating equipment will all create pressure losses and influence the pump's flow rate. Simply reading the manufacturer's documentation is no guarantee of optimum filtration pump flow.
The best way to optimize the operation of your pool pump is to use a flow meter. A flow meter or flow sensor provides an accurate measurement of the amount of water passing through your pool pump, and allows you to adjust the pump speed accordingly. This can help you save energy and money by ensuring that your pool pump isn't running harder than necessary. Knowing your pool's actual flow rate is essential for economical operation.
Unlike other technologies, ultrasonic flowmeters can be installed quickly, without cutting the water supply or stoppingyour pool. It provides real-time flow measurement in m3/h or l/min. The pool flowmeter is the most accurate way to save electrical energy while maintaining optimal water filtration and renewal. The flowmeter is installed on the pipe before or after the pool filter.
Installing variable-speed filtration pumps can offer significant advantages. It is one of the key ways of improving a pool's energy efficiency.
At the same time, optimizing water flow is another key factor. This can be achieved using an ultrasonic flowmeter, a precise and effective tool for controlling water consumption.
Finally, an appropriate control system, correctly parameterized and programmed, also has its part to play. By combining these strategies, substantial savings can be achieved. Specifically, these measures could reduce a pool's electricity bill by up to 35%.
The ultrasonic flowmeter improves the pool's overall energy balance, in line with the French Swimming Federation's recommendations on pool design.
