Announcements Archives - HyWin

The Swiss Climate Foundation informs us that the Milestone 4 report has been accepted. At the end of the winter season 20/21, HyWin is on track and 4 out of 6 milestones agreed with the Climate Foundation have been met. We would like to thank the Swiss Climate Foundation for the great and efficient collaboration!...

One of the important answers the test unit must deliver is, how well the room temperature is controlled under varying outside temperatures and solar radiation. The system monitors more than 50 different measuring points, recording temperatures, air pressure, water flow, humidity, solar radiation, pressure differences and more.  From these measurements it continuously calculates the balance...

Achim Geissler, Professor at University of Applied Sciences and Arts Northwestern Switzerland, FHNW in Muttenz (Switzerland), completed the HyWin simulation study supported by the Swiss Innovation Agency Innosuisse. The simulation gives a strong indication of the HyWin ability to ensure a comfortable indoor climate, both in summer and winter, without any additional  cooling or heating....

The extraordinarily hot and humid summer 2018 is a very tough test for HyWin.  Even with outside temperature of 35°C and full sun exposure over a large part of the day, the temperature inside the HyWin cavity is maintained at the desired room level of around 22-23°C. The high outside temperature also simulates the presence...

The test unit has been modified to measure the heat absorption  from internal heat sources.  The test results strongly suggest, that HyWin is able to compensate the usual internal heat sources in office buildings . Therefore no other cooling  devices are needed, making HyWin even more competitive.
