News portal vpnews. ru - about news about energy, trigeneration and modernization of housing and communal services
On the website vpnews. rucollected all the most important things from the world of energy, where every day events take place that change the life of cities and regions. This is not just a news platform - it is a live response to how the country is developing its capabilities, saving resources and introducing advanced technologies.
The site's topics are wide: from cogeneration to water treatment, from energy saving to modernization of housing and communal services. Particular attention is paid to trigeneration, which has long ceased to be exotic. Trigeneration is the production of electricity, heat and cold at the same time. Imagine an installation that operates all year round, even in summer, when it is usually stopped due to lack of heat. Now it can generate cold for air conditioning - in shopping centers, hospitals, stadiums. Just great, right?
How does it work? The cogeneration station provides heat that previously went into the pipe. But now it is used to create cold using absorption coolers. Yes, yes, such devices operate on steam, gas or hot water - which means they do not require expensive electricity. It is more profitable, quieter and more reliable than conventional compressor systems.
Why is absorption cooling the future?
Of course, there are disadvantages: high cost of equipment, large size, weight. But they can operate on cheap thermal energy. Or, let's put it this way, if you have waste heat, why pay extra money for electricity? Such solutions allow cogeneration units to operate without interruption all year round. This is savings, efficiency and a thoughtful approach to energy resources.
What about the principle of operation of the absorption system? As the solution heats up, refrigerant vapors are released, which then condense. The liquid refrigerant enters the evaporator, where it boils at a low temperature, removing heat from the room. Then the vapors return to the absorber, where they are absorbed by a weak solution. The process is closed, almost ideal. Everything works thanks to a thermal pump, which pumps the concentrated solution back into the boiler. The circle has closed as it should.
Interestingly, the site does not just inform, it offers context. There is a section for a Library of technical and commercial proposals from Industrial Systems LLC, as well as materials about culture - for example, a poetry competition named after Konstantin Kalinin or stories about the Last Date. This is no coincidence. The site is not strictly limited to technical news - here you can feel a living person who wants to share not only numbers, but also meanings.
Who is behind vpnews. ru?
The name of the company is not stated directly, but Industrial Systems LLC is mentioned, which provides technical and commercial proposals. Perhaps this is the main sponsor or partner of the site. There is also a reference to intertechelectro, energy and industry in Russia - all this indicates a close connection with industry.
In general, if you follow the development of energy in the country, want to understand how modern installations work, how they save money and resources - you definitely need this portal. It is not noisy, not intrusive, but very meaningful. Plus, there’s even a little poetry among the numbers. Well, who would have thought that in the world of trigeneration you could find a place for poetry?
Frequently asked questions
What is trigeneration and why is it needed?
Trigeneration is the simultaneous production of electricity, heat and cold. It is beneficial because it allows you to use the heat from cogeneration units even in the summer, when there is no need for heating. This extends equipment life and improves fuel efficiency.
How does absorption refrigeration work?
In short: a concentrated solution heats up, releasing refrigerant vapors. They pass through a reflux condenser, then condense and evaporate in the refrigerator compartment. The vapors are absorbed by a weak solution in the absorber, a concentrated solution is formed, which is sent back. Everything is cyclical and runs on cheap thermal energy.
Why are absorption systems better than compressor systems?
The main advantage is working on low-quality or free thermal energy. Compressor systems require a lot of electricity, while absorption systems can function without it. Plus they are quieter, more reliable and more durable. Yes, the initial costs are higher, but the payback is there.
Where can trigeneration be used?
In banks, hotels, shopping centers, hospitals, stadiums - wherever heat, cold, and electricity are needed. This is especially true for large facilities with high energy consumption.
