Industrial Heat Pumps
Generating Heat from Cold & Replacing Fossil Fuels
The heat transition in industry and commerce is unstoppable. Fossil fuels are becoming a financial risk, while valuable industrial waste heat is often wasted without being utilized. cold.world ENGINEERING turns the tables: We integrate high-performance large-scale heat pumps into your processes that either harness ambient heat or hydraulically convert your cooling systems into heating systems. This allows you to lower your primary energy demand and reduce CO₂ emissions in a measurable and verifiable way.
High-Temperature Heat Pumps Using Natural Refrigerants
A common misconception is that heat pumps can only provide low flow temperatures for radiant heating systems. This is physically outdated. By using natural refrigerants (GWP 0 to 3), we design systems with flow temperatures that are ideally suited for industrial processes and existing buildings:
Ammonia (NH₃): The standard for large-scale heat pumps in the megawatt range. Highly efficient at flow temperatures up to approximately 90 °C.
Carbon dioxide (CO₂ / R744): Thermodynamically unbeatable for hot water production or in processes involving large temperature differentials (heating).
Propane (R290) & isobutane (R600a): As high-temperature heat pumps, they enable flow temperatures ranging from 80 °C to over 90 °C—the ideal replacement for fossil fuel boilers.
The Principle of Heating and Cooling in a Single Step
1. Refrigeration system as a heat source:
Instead of allowing the waste heat from your cold storage facilities or production processes to be released unused into the environment via recoolers, a heat pump raises this temperature to a usable level.
2. Combined benefits:
They generate cooling for production and heat for heating or cleaning using a single source of primary energy. This results in a massive increase in the coefficient of performance (COP) of the entire system.
3. Independence from fossil fuels:
Every thermal kilowatt-hour (kWh) that the heat pump delivers no longer needs to be generated from fossil fuels by the gas boiler.
Applications for Our Heat Pump Solutions
We don’t design off-the-shelf solutions for single-family homes; instead, we provide robust engineering solutions for industry, commerce, and municipalities:
- Process heat: Providing wash water, integration into drying processes, or preheating boiler feedwater.
- Logistics & Administration: Heating of office buildings and logistics warehouses (often highly efficient when combined with concrete core activation).
- District Heating & Local Heating: Feeding heat from large heat pumps into local heating networks (e.g., river water or wastewater heat pumps).
- Food industry: Slaughterhouses, dairies, and breweries require large amounts of hot water (60 °C+) for cleaning. In these applications, heat pump technology offers unmatched efficiency.
Frequently Asked Questions About Large-Scale Heat Pumps
Are there subsidies available for industrial heat pumps?
Yes, and substantial ones at that. The federal government often supports the decarbonization of process heat (e.g., through the Federal Funding Program for Energy and Resource Efficiency in Industry—EEW) with high percentage-based investment grants. As a planning firm, we support you in developing technical concepts and thermodynamic analyses to make the most of these funding opportunities.
Can a heat pump replace my steam boiler?
In practice, we often design highly efficient hybrid solutions: The heat pump handles the base load and preheating, while the steam boiler covers only the peak load. This significantly reduces fossil gas consumption.
