More than 8 hours of cold air
Solar heat can be used not only for heating, but also to cool the air in the room in summer.
When it is warmer in an environment is that you need to condition the air of a closed environment such as a house, office or work in enclosed spaces, this is coincidence with the days of maximum solar radiation.
The key is how to relate this air conditioning to adapt an environment without the need to consume electricity from conventional power grids. This is where the use of technical systems to use renewable energies such as wind or solar radiation enters our minds. Feed with solar energy, for example, a known air conditioning system instead of plugging into the line of electric cables sold to us by the electric company.
In Lima and many places in Peru, a summer of extreme temperature, perhaps above 40 degrees Celsius, is coming, as the experts are announcing.
We must be prepared to counteract this unusual weather phenomenon.
With five hours of sun daily and the use of photovoltaic modules, eight (8) hours or more of air conditioning is achieved thanks to these photovoltaic solar panels only.
Solar air conditioners are those that use solar energy to transform electricity (photovoltaic) and solar thermal air conditioners (the sun is used to directly heat a refrigerant or refrigerant).
Clean and economical, but often of a small or medium power, these air conditioners can provide primary and supplemental air conditioning.
3. Split type
Air Conditioning with Solar Photovoltaic Panels
Units of type ‘split’ with characteristics of common systems and solar panels of 265 Wp for 12000 BTU.
The big difference is that these air conditioning units produce their ‘own energy’ without having to resort to wired installations or cables or conventional poles.
These new air conditioners with ‘solar panels’ are equipped with “rotary compressors with permanent magnet motors without brushes of 48 V DC driven by one, two or more ‘solar panels’ according to the size according to the availability of area for support structures.
Solar radiation is used in the summer season or thermal surpluses to transform them into cold environments in the house, office or business environment enclosed.
In this scheme we see a possible configuration of a conventional cooling system supported by solar energy.
The solar system has accumulation in order to cushion the lags between the availability of radiation and the refrigeration load.
You can use solar thermal directly to produce cold and have air conditioning, without the need to convert solar energy into electricity.
4. Important Factors before buying
What we consider for the solar generator: we put our heads together with a list of important criteria that we would like for our system:
- 100% solar.
- Solar energy input Minimum 750 W DC power 30 VDC.
- Cost / Size / Weight.
- Easy portability.
- Friendly use.
- Recharge and technology fee: charge from AC to DC, solar panels, DC (battery to battery).
- Output power: 220 volts AC and 12, 24 or 48 volts DC.
- 12000 BTU, cooling solar energy air conditioner.
- Better if you find Air Conditioning Appliances that DO NOT REQUIRE Alternating Current (AC) power.
- Wireless remote digital operation.
- Autonomy, minimum of 48 hours (two days without sun, cloudy or rainy environment). That for two days the Air Conditioning device works normally.
- That has no need to use INVERSOR. The device must be DC (DC).
- With anti-corrosive and silent technology.
From an ecological point of view, solar cooling is far superior to conventional air conditioning systems.
The overall efficiency of an air conditioning system is almost catastrophic, based on primary energy consumption.
In this respect, the ecological advantage of a solar air conditioning system compared to a conventional one is once again significantly greater than the ecological advantage of a solar heating system, provided that this does not replace a current heating system.
