Air solar collector for heating a house

Investigating alternate heating options becomes essential as we work to make our homes more ecologically and energy-efficient. The use of air solar collectors is one such technique that is becoming more popular. These cutting-edge gadgets use the sun’s energy to heat homes, giving homeowners an affordable and environmentally friendly option.

Air solar collectors harness the abundant and renewable energy of the sun, in contrast to conventional heating systems that depend on electricity or fossil fuels. These collectors are basically made up of a number of panels that are mounted on a house’s outside walls or roof. The purpose of these panels is to take in solar radiation and transform it into thermal energy, which is then transferred to the air that circulates within the collector.

Air solar collectors’ ease of use and low maintenance needs are two of their main benefits. Simple air circulation is used by air collectors to transfer heat, in contrast to more sophisticated solar thermal systems that use liquid. They are therefore a sensible option for homeowners who want to lower their energy costs without having to perform ongoing maintenance, as there are fewer parts that could break down or need to be serviced frequently.

Additionally, air solar collectors offer flexibility in installation and usage as they can be used as standalone units or seamlessly integrated into already-existing heating systems. These collectors provide flexible options to meet your needs, whether you’re looking to switch entirely to renewable energy or just add more heating to your existing system.

We will examine the operation, advantages, and installation considerations of air solar collectors in greater detail in this article. Homeowners can contribute to a more sustainable and environmentally friendly future by installing air solar collectors into their homes by being informed about the potential of this cutting-edge technology.

How the air collector works

  • The case with thermal insulation;
  • lower screen, absorber;
  • radiator with accumulating ribs;
  • upper part of ordinary glass or polycarbonate.

The collector’s design incorporates fans. The main objective is to heat the air inside residential buildings. Forced convection is produced when the fans run, which allows cold air masses to enter the collector block.

The air solar collector is a clever way to provide your house with sustainable heating. This system uses solar energy to collect heat from the sun and distribute it throughout your home. The air solar collector works effectively and economically, decreasing your dependency on fossil fuels and your utility costs, in contrast to conventional heating methods. It’s an environmentally friendly way to maintain a warm and inviting home all year round with easy installation and little upkeep. For your home heating needs, say goodbye to cold winters and hello to a warmer, greener future with the air solar collector.

The principle of heating and its effectiveness

To intensify heating caused by solar radiation, air collector absorbers are constructed of black material. The manifold’s air temperature reaches 70–80 °C. Excess heat is sufficient to fully heat a small area’s premises.

The air heater works on the following principle:

  • The air is pumped from the street to the collector’s body in a compulsory way;
  • Inside the block, the absorbers are installed, reflecting heat, raising the temperature inside the box to 70-80 ° C;
  • air heating occurs;
  • Warm air masses are forcibly pumped into heated rooms.

Fans that are connected to solar panels are used in factory models to provide air circulation. Turbines are activated when UV radiation reaches a threshold intensity, which determines how much electricity can be produced. In order to heat, collectors start working. The sun’s radiation is less intense during the winter.

Sunlight air heating will not allow the house to operate to its full potential. An additional source of heat is provided by air heaters. One installation (data derived from the technical specifications of the Solar Fox air solar air collectors) should guarantee the following savings during the heating season, provided the calculations are done correctly:

  • gas up to 315 m³;
  • firewood up to 3.9 m³.

The building’s required heat is offset to the tune of approximately 30% by the solar air heating system. Repayment is completed in two to three years. The practicality of use is further demonstrated when we consider that the principle of operation relates to the use of the installation and for air conditioning, and that approximately 4000 kW is produced annually.

The "Solar Wall" design solution was widely used in EU member states. The layout is as follows:

  • In the building, one of the walls is made of accumulating material;
  • A glass partition is installed in front of the panel;
  • The heat is accumulated during the day, after which it is given to the room at night.

The solar collector is not installed throughout the wall in order to improve convection. There are sliding curtains on the top and bottom.

The time of year has a major impact on the air collector’s efficiency. Thus, the efficiency coefficient remains at 50% in December and rises to 75% in October and March.

Solar collector – water or air

All of the heaters are functional; the primary objective and operational principle vary only slightly:

  • Water collector – used to meet the needs for hydraulic devices and low -temperature systems of warm floors. The effectiveness of work in the winter period is significantly reduced. Vacuum and panel collectors of indirect heating, connected to the buffer capacity, continue to accumulate heat throughout the year. The main drawback, the high cost of a heliocollector, installation and strapping.
  • Air ventilation collector – is characterized by a simple design and device, which, if desired, can be made independently. Main purpose: premises heating. Of course, there are schemes that allow the use of the resulting heat for the hot water, but the efficiency of air collectors almost doubled. Advantages: Low cost of the set and installation.

Only in the daytime do solar air heating systems operate. Even in overcast skies, especially when it’s raining, air conditioning kicks in. Throughout the winter, air conditioners continue to operate.

How and from what to make an air collector

The primary benefit of solar air heaters lies in their straightforward design. If desired, you can install inexpensive solar air heating in a private home by investing a minimal amount of money.

You must first determine the type of structure to be built, calculate performance, and select manufacturing materials. Improvised methods can be used to create corps and absorbers at a significant cost savings.

How to make a collector calculation

The following computations are carried out:

  • Each m² from the area of the collector will give 1.5 kW/hour of thermal energy, provided that there will be sunny weather;
  • For a full heating of the room, 1 kW of thermal energy is required by 10 m².

Based on an approximative power calculation, collectors with a total area of 7-8 m² must be installed in order to heat a residential building per 100 m².

Finding the side of the house with the highest UV radiation intensity is essential to ensuring optimal performance. Experience has shown that the southern wall of the building or a roof slope are the best locations for installations.

Types of the design of the collector

The distinctions in the collector housing are used to carry out classification. Typically, the factory air heater features two detachable panels on an inflatable frame. The module is easily disassembled, dismantled, and moved to a new location if needed. You won’t be able to accomplish it with your hands.

An assembly of a non-vegetable case is done at home. This wooden box has a transparent screen on top, a radiator, and an absorber. Ordinary glass, aluminum beer jars, and corrugated board are among the makeshift tools used in the manufacturing process.

Materials for the manufacture of a collector

To produce heating modules for residential or commercial buildings, a few things will need to be assembled:

  • External block – assembled from plywood, chipboard and wooden bars. In appearance resembles an ordinary box.
  • Bottom – made from corrugated board. The metal sheet is treated with special black paint with a high coefficient of lighting. The absorbing surface can be made from cut aluminum cans. The bottom is sheathed with insulating material to avoid thermal losses.
  • Radiator ribs – used for better heat absorption. In the manufacture, thin sheets of aluminum, copper are used. You can install a ready -made radiator from an old refrigerator.
  • Collector cover – made of cellular polycarbonate, which differs with good light outlet and at the same time holding heat inside the collector. To save, you can use ordinary glass as a coating. Thermal efficiency will be in the need for collectors closed by polycarbonate.
  • Thermal insulation of the case – along the perimeter, the frame is sheathed with polystyrene foam.

Two to four fans are installed to force air into heated rooms. The old PC’s suitable coolers were taken out.

Installation and connection of air collector

You must prepare the wall’s surface by drilling four holes for the air ducts before installing air heaters. The building’s rooms contain corporal pipes that are diluted and directed towards the floor.

The transformer connects the DIY air solar collectors used to heat the home to the main electricity supply. One option for installing a battery is to use skills as a power source.

Compared to factory-produced goods, the DIY air heaters’ heat efficiency is noticeably lower. When one lacks specialized knowledge, pre-made modules are preferable. Based on genuine reviews from collectors, Solar Fox, Solstar, and Yasolar-Air are the best options available on the domestic market.

Air heaters only serve as an auxiliary source of heat and are not utilized as the primary source. Initially, a boiler is installed in homes with solar air collectors to meet 100% of the heating needs.

The investment will pay for itself in a year or two with careful calculations and diligent work. If the collector is made independently, the costs will be recouped by the middle of the first heating season.

A viable way to lower energy costs and your home’s environmental effect is to install an air solar collector for heating. These systems effectively capture solar energy to provide warmth during the winter months by harnessing the power of the sun.

The affordability and ease of use of air solar collectors are two of their main advantages. In contrast to alternative solar heating systems, they don’t need pricey equipment or intricate plumbing. Rather, they depend on fundamental concepts of ventilation and heat exchange, which enables homeowners seeking to reduce their heating expenses to utilize them.

Air solar collectors also provide flexible installation options. Depending on the particular requirements of the home, they can be installed as standalone units or integrated into already-existing heating systems. Because of their adaptability, they can be used in a variety of homes, regardless of size or design.

The comparatively low maintenance needs of air solar collectors are another benefit. These systems can function effectively for years with correct installation and periodic cleaning, giving steady warmth without requiring frequent maintenance or repairs.

To sum up, air solar collectors are a useful and environmentally friendly way to heat residential buildings. These systems give homeowners the chance to minimize their carbon footprint and lessen their dependency on conventional heating methods by utilizing the sun’s abundant energy. Future home construction could benefit greatly from the use of air solar collectors because of their ease of use, low cost, and high efficiency.
