A renowned hospital in Meyrin, Switzerland 🇨🇭 was the site of a milestone project for Skawen.
We installed a single unit from our SKW Comp1500 RHP-TIR series with all duct connections on the top of the unit to reduce the installation foot print in the mechanical room. This system was designed to effectively manage the ventilation for medication storage, hospital-stocked material, and a reception area where a constant temperature needs to be maintained.
A distinguishing aspect of this project was using a combined high efficient reversible heat pump system with our highly efficient counterflow heat exchanger with Bypass.
This technology captures not only the energy in the building by extracting the energy in the air through the counterflow exchanger but using inverter heat pump technology to add only the partial or full load of energy required to maintain the constant temperature set by the building. These attributes managed by the state-of-the-art controller bring the working point on demand temperature and ventilation requirement.
This technology and system is the backbone of the swimming pool application where each air handling unit needs to multi-task between dehumidification of the room air, maintaining air temperature of the room air, and contributing to the pool water temp through the energy gained through the air with an additional inverter heat pump to add the missing heat required to air or water.
Notably, this project marked our first successful application of this system for automatic seasonal conditions required in cooling or heating. The project presented us with several technical challenges. We ensured the operations complied with EU and CH standards, keeping the air speed inside the unit below 2 m per second to reduce the operating pressure required by the system.
The system now operates under the hospital's SAIA BMS's supervision and has secured rigorous approvals for the city and the state of Geneva.
Despite the rise in energy costs since the project's completion, our solution continues to efficiently balance heating and cooling, highlighting our commitment to energy conservation. The positive feedback received from the hospital has paved the way for discussions about potential installations within their other facilities.
