Overview

Efficient and Cost-effective Solution

Heat pumps are an efficient and cost-effective solution for the generation of heat and cold. They lift the temperature by absorbing thermal energy from an existing low-temperature heat source and releasing it to a warmer space. The use of a heat source (e.g., waste heat from industries or renewable heat from nature, like rivers or geothermal sources) enables heat pumps to generate much more heat with a certain amount of electricity, than a simple direct conversion of electric power to heat could do.

During the next years, heat generation will be electrified and decarbonized step by step, due to the gradual replacement of fossil-fired thermal power plants with renewable energies. Excess capacities of renewable energy can be converted into heat, paving the way to CO2-free heat generation. For modern district heating and cooling or industrial heating applications, Withair’s large-scale industrial heat pumps are the best and most efficient solution to convert electricity to heat.
Basic Principle of Heat Pumps

How can you produce heat without heating up the climate?

Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer, by absorbing heat from a cold space and releasing it to a warmer one.
Environmentally Friendly Refrigerants

Withair’s heat pumps use modern, energy-efficient, safe and non-hazardous working fluids. The refrigerants have negligible environmental impact in all aspects:

Non-toxic
Non-corrosive
Ultra-low global warming potential (GWP)
No ozone depletion potential (ODP)

We see refrigerants as a design element of a heat pumps system. We will use the optimum refrigerant for the specific solution.
Potential Heat Sources

Industrial Sources: Chemical & petochemical industrial, refineries, Steel works, Pulp & paper and fiber industry, Power generation waste heat, Sewage water, Data center, etc.

Natural Sources: Air, Geothermal energy, Water in lakes, rivers and sea, etc.
Fields of Application

Withair® Large-scale Industrial Heat Pumps provide significant efficiency, sustainability and reliability improvements over traditional heating systems.

Heat pumps are sustainable, efficient replacements for natural gas and electric boiler-based water and space heating/cooling systems. An excellent technology candidate for building retrofits and new facilities, heat pumps can be utilized within food processing, industrial manufacturing, district heating, and building HVAC applications. District heating and/or cooling; Efficient use of energy in industries, e.g., food & beverage, chemical, petrochemical & pharmaceutical, pulp & paper； Hydronic heating; Space heating; Sanitization

This eco-friendly heat pump solution reduces greenhouse gas emissions and improves energy efficiency while offering load flexibility to building operators.
Key Benefits

● More efficient than direct conversion of electric power to heat.
● Simultaneous production of heat and cold.
● Low levelized life-cycle cost of heat for long term economic solution.
● Easy to integrate in existing processes and applications.
● Proven, reliable technology: Heat pumps are commonly available and attached to households, large-scale is just up-scaled.
● Waste heat can be re-used and sold for other purposes, connecting different applications (enabling new business models).
● Power grid stabilization: Peak shaving for excess power generation to balance supply and demand, surplus power from renewable sources can be converted into heat.
