Key Renewable Technologies for Industrial Cooling
Solar-Powered Cooling (PV and Thermal)
Solar Photovoltaic (PV): These systems convert sunlight directly into electricity that powers conventional vapor compression chillers. Solar PV panels can be installed on rooftops, ground-mounted arrays, or integrated into building facades. The electricity generated flows directly to cooling equipment or energy storage systems for later use.
- Modern PV systems convert sunlight to electricity with 20-22% efficiency.
- Large installations produce several megawatts of clean energy during peak sunlight.
- Smart inverters optimize power flow between solar panels, cooling, and the grid.
- Pairing PV systems with batteries ensures power for cooling during evenings or cloudy periods.
- Advanced energy management systems switch between solar, storage, and grid power to reduce costs and ensure reliability.
Solar Thermal: This technology captures solar heat to drive absorption or adsorption chillers that produce chilled water without electricity. Solar thermal collectors harness sunlight to heat a fluid, such as water or specialized heat transfer liquids. The heated fluid then provides the thermal energy needed to operate thermally driven cooling equipment.
- Solar thermal systems are more efficient for cooling as they skip the electricity conversion step.
- Direct thermal collection efficiency: 60-80% vs. 20% for PV panels.
- Common technologies: parabolic trough collectors and evacuated tube systems.
- Can produce temperatures of 150-200°C, suitable for most absorption cooling systems.
Geothermal Cooling Systems
Geothermal heat pumps harness the consistent underground temperature of the earth to provide energy-efficient heating and cooling. Below the frost line, soil temperatures remain relatively constant year-round, typically 50-60°F in most climates. This provides an excellent heat sink for cooling operations and a heat source for heating applications.
- Closed-loop geothermal systems use buried pipes to circulate fluid that exchanges heat with the earth.
- Excess heat from buildings is transferred underground, leveraging stable ground temperatures for efficient cooling.
- Geothermal heat pumps achieve COP values of 3-6, providing 3-6 units of cooling per unit of electricity, compared to 2-3 COP for traditional air-conditioning systems.
- Direct-use geothermal systems use natural hot water or steam to power absorption chillers.
Biomass-Fueled Cooling Solutions
Biomass cooling systems are an innovative and sustainable solution for industrial cooling needs. By utilizing organic materials like agricultural waste or wood chips, these systems provide an eco-friendly way to generate cooling while reducing waste and carbon emissions.
- Biomass fuels include agricultural waste (rice hulls, corn stalks) and forestry byproducts (sawdust, wood chips), turning waste into valuable energy inputs.
- These systems use thermal energy from biomass combustion to power absorption chillers, which produce chilled water for industrial cooling.
- They support a circular economy by eliminating waste disposal costs and repurposing waste streams as energy sources.
- A major advantage is carbon neutrality: the CO2 released during combustion is balanced by the CO2 absorbed by plants during their growth, resulting in zero net greenhouse gas emissions when sustainably managed.
How Renewable Energy Integrates with Industrial Cooling Systems
Direct Electrical Power (for Vapor Compression Chillers)
Solar PV arrays and wind turbines can directly supply electricity to power traditional compressor-based chiller systems. This straightforward integration approach requires minimal modifications to existing cooling infrastructure. The renewable electricity simply substitutes for grid power while maintaining familiar operating procedures.

Thermal-Driven Cooling (for Absorption/Adsorption Chillers)
Solar thermal collectors, geothermal heat, and biomass combustion provide high-temperature thermal energy that drives absorption or adsorption cooling cycles. These thermally-activated systems replace electricity as the primary energy input for cooling production. Hot water or steam at 180-250°F activates the refrigeration cycle.
- Absorption Chillers: Use heat to separate refrigerant from an absorbent solution (e.g., water-lithium bromide, ammonia-water).
- Adsorption Chillers: Heat drives moisture out, and cooling occurs during reabsorption. Ideal for low-temperature heat sources.
- Thermal Storage Systems: Store hot water or heat transfer fluids in insulated tanks to provide cooling when renewable heat sources are unavailable. Can maintain temperatures for hours or days, depending on design.
Ground-Source Heat Exchange (for Heat Pumps)
Geothermal heat pump systems use underground loops to exchange heat with the earth, leveraging its stable temperatures for efficient cooling.
- Heat pumps can provide heating and cooling simultaneously, using rejected heat to warm other building zones or processes, improving efficiency and reducing energy use.
- Variable speed drives and advanced controls optimize performance by adjusting refrigerant flow and compressor speeds to match cooling demands, minimizing energy consumption.
