In the eyes of many customers, photovoltaic or cogeneration installations are financially very similar to CO2 refrigeration. The principle of this business can be described as a capital expenditure (CAPEX), which reduces operating costs (OPEX), giving a payback after some time, and then a real profit (net gain). The principle of creating savings thanks to the technologies described above is, however, significantly different, and therefore subject to other associated risks
with legal regulations.
Cogeneration or photovoltaic installations produce cheaper or free energy. Their possible use does not affect the amount of energy consumed by the devices powered by them. So refrigeration powered from the grid or cogeneration will still have the same COP.
On the other hand, CO2 refrigeration (including chillers and heat pumps) use significantly less energy, no matter where it comes from or how much it costs. So it’s getting the same effect in a completely different way.
As a result of a very large and constantly growing number of individual energy generation sources, such as those described above, the power grid in Poland is becoming more and more difficult to balance. Sooner or later, the power industry will put a muzzle on the free flow of energy into the grid. In the industry press, you can already read about increasing difficulties in obtaining connection conditions or about negative energy prices.
What is the conclusion?
I believe that in the coming years, the energy generated in own micro power plants (PV or cogeneration) will have to be consumed on its own (production plant or cluster). This will be done in a follow-up mode or with the use of electricity banks or in yet other forms.
However, the energy phenomenon described above will not affect the possibility of using highly energy-efficient refrigeration. It may even be an impulse to use cold or heat banks, which will be charged when own energy is available and unloaded at peaks of cooling or heat demand.
It’s good when the refrigeration works – we can provide that and it doesn’t use a lot of energy unnecessarily – we’re really good at that. It’s probably not modest. Refrigeration is important to us. We believe… we know that a well-designed and executed cooling system in the plastics processing industry can make all the […]
Electric cars, photovoltaics, heat pumps – these are topics that, in the broadly understood utility of consciousness, operate on a daily basis. Everyone has an opinion on them, including breakfast TV presenters and politicians. On two topics I will not stand out, but on heat pumps that I have the right and competence. Fortunately, one […]
A sailing ship needs wind to move towards its destination. The stronger it is, the faster the boat moves forward. However, when the wind is too strong, it jerks the sails and raises waves that can sink an entire ship. The situation of companies in our industry is similar. He laughs himself at how […]
