Solutions & Tech Applied
The installation is an air to water heat pump localized in an arctic environment and naturally in a cold climate zone. The system solution is a 3-pipe VRF system, and the installation is proof that air to water solutions also work perfectly in a colder Norwegian winter climate. The system solution is connected to a central control system, and melting of snow outdoors is automatically controlled using data from the Norwegian weather forecaster Yr.no. The system solution is very innovative since it SIMULTANEOUSLY provides heating, cooling and domestic hot water. Polar Energi does not know of any comparable system solution anywhere in the world. With the patented PSHI™ technology developed by the company, together with highly efficient ECOi Panasonic outdoor units, the hotel is pleased about a SCOP of no less than 4.8.
After the expansion, the total building area is approximately 10,000m2, with 200 guest rooms and a conference centre for up to 780 participants. The energy efficiency is extremely good, with a SCOP of no less than 4.8. As an example, the total energy consumption related to the installation was only 10,000kWh for September 2021. The investment will be completely paid off in only 3.5 years
Key Tech Features
DHW, which is fed to peak load heaters, is sufficient to cover the total hot water requirement.
