How Photothermal Hybrid Solar Air Conditioner Works to Save Energy?

[abstract]

Sunflower Energy currently provides 4 types of photothermal hybrid solar air conditioners: Wall-Mounted Type-- Floor Standing Type-- Cassette Type-- High Pressure Duct Type. Each of them has different models with different capacities for different room areas. One of the most important advantages of the photothermal hybrid solar air conditioner is that it is energy saving, which can save at least 30% on electricity bills. This article will tell you how the system works to save energy.

The standard set of the photothermal hybrid solar thermal air conditioner system includes 3 parts: indoor unit, outdoor unit and solar collector; Usually, the solar collector (glass vacuum tube type or flat plate type) is mounted with outdoor unit.

The photothermal hybrid solar air conditioning system uses both AC electrical power (220-240V, 50Hz/60Hz) and solar thermal energy. The same as traditional air conditioner, this air conditioning system always requires mains electrical power to operate fans and electric control components.

The air conditioning system uses solar thermal energy as an energy source to help maintain the refrigeration process which in turn reduces the amount of electrical energy required to run the compressor.

Firstly, it absorbs solar energy to heat the inside medium by using a solar collector. R410A gas from the compressor goes through the copper coil inside the collector and undertakes a heat exchange. Freon exchange heat with the medium (hot water) inside the solar collector then go through a cycle inside the system for cooling and heating.

Secondly, it adopts a highly efficient heat-exchange system. The use of the internal thread pipe, hydrophilic aluminum fin and the optimal heat exchange system reduce energy loss, improve the overall efficiency and effectively ensure the performance. Therefore, photothermal hybrid solar air conditioner is more convenient and energy-saving than regular air conditioner.

In a short word, this photothermal hybrid solar air conditioning operates under the same principles as a traditional air conditioning systems where refrigeration takes place as a result of the phase transition of the refrigerant.

The difference between this solar air conditioning and a traditional system is how the vapour is changed back into a liquid state in the refrigeration cycle.

Comparing to Current Products
1. Conventional air conditioner consumes too much and users have to pay a heavy electricity bill.
2. Hybrid DC inverter solar air conditioner can not save electricity during nights.
3. 100% DC48V solar air conditioner uses Photovoltaic (PV) system costs a large amount of money to build up.

Tips on electricity saving of air conditioners: According to China National Management Method of Energy Efficiency, EER refers to the proportion between cooling capacity and power input, which is the only data used to value the energy-saving of air conditioners. The bigger it is, the electricity it saves. If two AC with the same power consumption, the one with bigger capacity is better on electricity saving.

[Conclusion]

Compared to other types of solar air conditioner, photothermal hybrid solar air conditioner are now available at an affordable price so systems can pay for themselves within a very short time. Compared to conventional air conditioner, this thermal solar air conditioner can save 30%~50% electricity, which help you to reduce lots of electricity expenses over year.
