Light-emitting diode lamps become a more popular choice for lighting. They consume 75-80% less energy compared with traditional incandescent lamps and serve 25 times longer. However, even such energy-efficient sources of light can exert impact in special conditions, such as freezer chambers. Consider the possibility of using chiller freezer with efficient light-emitting diode lighting.
Principle Action LED and Phenomenon Heat Emission
LED lamps work with the use of semiconductors, where light emits at passage electrical current. Despite high efficiency, light-emitting diodes all convert about 20% of energy into heat. In large freezer chambers with many lamps, each light-emitting diode can raise the temperature to 0.5°C. This is important, considering that many products lose their freshness at exceeding temperature threshold even at 1°C.
Hidden Risks Heat Impact LED on Freezer Chambers
Temperature inside freezer chamber must remain stably low for preservation of freshness products. At the installation of several LED lamps, internal heat load can increase by 10-30%, which compels systems cooling to work at a limit. This leads to increased wear compressors and increased expenses on electricity by an average of 15%.

Impact on Energy Consumption and Preservation Products
Light-emitting diode lamps, emitting additional heat, require enhanced work cooling systems. In American supermarkets, modernization was conducted, and this lasted two years. The consumption of electricity fell by 18%, and this is all thanks to the installation of more efficient light-emitting diodes and improved cooling systems.
Strategies on Minimization Heat Impact
- Change Construction Light-emitting Diodes: Use low-temperature diodes allows reduce heat load to 5%.
- Engineering Innovations: Installation radiators and fans will reduce local heating.
- Systems Management Lighting: Automatic regulation intensity lighting on 15% reduces energy expenses.

Successful Examples and Trends
Large network supermarkets replaced standard fixtures on modernized LED models. The results of the project were striking: energy expenses were reduced by 20%, and the temperature balance in the chambers stabilized. This allowed an increase in term service refrigeration installations by 25%.
These solutions have already found their realization in the top 3 largest networks in the USA. Active cooling light-emitting diodes are installed in 30% of large retail points in Europe. This demonstrates that thoughtful management of heat emission can significantly increase the efficiency of work freezer chambers, reducing energy consumption and improving storage products.
