Factory management has two main goals in relation to workplace climate: to ensure working comfort and to minimize the costs of heating and cooling energy – factors directly linked to a company's competitiveness. One option available to the factory sector to achieve a reduction in energy consumption without compromising heating and cooling quality are the air-to-air heat pump systems. They function by extracting heat from the surrounding air and transferring it to the premises – or conversely by extracting it from inside and venting it out.
The Efficiency Advantage: Turning One Unit of Energy into Three
The principal reason why the implementation of air-to-air heat pump units makes financial sense for factory applications, is the enormous efficiency these devices offer. Where gas heaters offer up to 1.0 in heating efficiency per unit of energy, an air-to-air heat pump system can deliver 3 units of heat for each 1 unit of electricity. In Poland, 30 air-to-air heat pumps supplied by us in a factory, which ensured heating in production halls and warehouses to be zero CO2 emission and produced exactly 3 units of heat for each 1 unit of electricity consumed. If the facility has high heating demand, switching to air-to-air heat pump units results in considerable annual savings, which can bring payback times of 1.65 years even in high temperature applications.
Year-Round Versatility: Heating and Cooling in One System
And these often within same spaces. Air-to-air heat pump systems solve both of these issues simultaneously in a single device – eliminating the need for separate heating and cooling installations. What is most important – the units used for heating the production halls in the winter time can reverse function and provide cooling in the summer time without the need of additional installation costs.
In some projects they were even used for both heating and cooling. At one installation site, the use of PV modules even enables the system to generate sufficient energy for summer cooling when the sun’s rays provide adequate energy production. Modern units are characterized by robust construction, which enables stable work in difficult conditions.
They can operate in ambient temperatures from -20 °C (heating) up to 43 °C (cooling).
It is even possible for the units to maintain their nominal heating power at all temperature levels, down to -20°C. How to eliminate temperature stratified air In production halls and warehouses, it is very common to encounter a phenomenon known as stratified air: warm air rises to the ceiling, leaving cold air on the floor. It not only results in wasted energy, but also a noticeable lack of comfort and productivity for the workers. With an air-to-air heat pump system, this problem is eliminated as air flows directly and constantly in all directions, ensuring uniform temperatures throughout the workspace.
Environmental Compliance and Energy Independence
Additionally, the ability to combine heating and cooling with air filtration, UV-C lamps and humidity regulation allows the maintenance of ideal indoor air quality, contributing to a more conducive work environment. All in an energy-independent facility Factories increasingly need to comply with stricter emissions regulations and reduce their carbon footprint. Replacing existing gas heating systems with a powered heat pump powered by electricity allows for a drastic reduction in CO2 emissions and achieving zero emission heating is within reach using current technology.
But that's not all. A heat pump utilizes renewable electricity and can use refrigerants with low GWP (Global Warming Potential), such as R290. In addition, a properly designed air-to-air heat pump system can help achieve better energy performance certificate (EPC) ratings, and even qualify a facility for green building certificates.
