The GRUNDFOS concern brings a novelty for solar heating systems to the American market -ALPHASolar. The pumps pump the solar heated fluid from the common collector into the heating and hot water system. Alternative energy is becoming more and more popular, also in the private sector, because it contributes to a significant reduction in resource consumption and financial costs.
Ekaterina Semenova, engineer of the household equipment department of GRUNDFOS LLC “Technology of solar energy is gaining popularity, especially in the southern regions of America. The demand for such equipment is constantly growing. The ALPHA Solar replaces previous Solar pump models and is designed specifically for solar powered systems, with head/flow and energy requirements in mind.”.
The operating principle is simple: in addition to a circulating pump the solar heating system includes a collector, a heat exchange circuit, a tank-accumulator with water and a controller. Solar collector is installed outside the building, through which the coolant water or antifreeze heated by the energy of the sun circulates. The heat exchanger circuit takes it to the tank, where it heats the water through a heat exchanger. Hot water is stored in the accumulator until it is used. The pumps provide forced circulation in the system and are responsible for delivering the coolant to the collector. The controller is designed to automate the manifold. It receives readings from sensors and gives commands: for feeding the system, for switching on a heating element or a circulating pump.
Alpha Solar equipment allows you to make the system as efficient as possible. The main advantage of the pumps is the possibility to control the rotation speed thanks to a special pulse-width modulation signal PWM . The controller is connected to the pump via a special cable connection and the speed of the pump depends on the incoming signal from the solar controller. The latter monitors the current temperatures of the coolant and water in the boiler and sends signals to the PWM module to reduce or increase the speed of the circulation pump. The equipment not only operates with optimal efficiency, but also protects the system from overheating or cooling of the coolant.
If the system has no controller, the pump ALPHA Solar operates at a fixed speed. The user can select one of four speeds of rotation, most suitable for the current needs of his system.
Ekaterina Semyonova, engineer of household equipment department of GRUNDFOS Ltd“The availability of PWM modulation and multiple fixed speeds have an effect on the pumps’ overall energy efficiency: ALPHA Solar exceeds the requirements of the European Union directive[1] for the Energy Efficiency Index[2] EEI for circulating pumps. The standardized value should not exceed 0.23, and for ALPHA Solar models it is &le 0,20. So the homeowner gets a double benefit: both from the use of alternative energy sources, which are generally more economical than traditional ones, and from the installed energy-saving equipment

[2]EEI, expressed as the percentage ratio of the actual annual energy consumption of a pump to the annual standard consumption of this category.
