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 HyWin Webpage has been refined and updated

After 2 years the webpage required some updates, such as the smartphone and tablet format, information about the outdoor tests as well as the upgraded simulation tool II.

HyWin - outdoor test during the hot and humid summer 2018

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 of internal heat sources, such as computers or  people, since in the test unit the "inside" window is actually exposed to the high external temperaures. HyWin fully absorbs, as expected, the heat that enters through the "inside window"

HyWin - outdoor installation completed and tested

A new outdoor test unit test fully confirms the laboratory tests.  The energy removal from HyWin correlates with the global sun radiation. HyWin dynamically reacts to variations of sun radiation due to clouds

HyWin - successful test of the the cooling functionality

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.

Optimized Closed-Cavity Hybrid Window for Glass Façades

HyWin HLSU Facade 2016_presentation

Authors:
Claudio Meisser and Jan Lipton, Switzerland

Short Abstract:
HyWin, the newly designed Closed Cavity window with an integrated highly efficient air/water heat exchanger and controlled air circulation allows the active control of the window behavior for different regimes of sun radiation and external temperatures from strong sun radiation on hot summer days to cold winter nights. The design, the results from experiments and simulations will be shown. The operational aspects of HyWin and the strategy for energy storage in ground probes for buildings with different user profiles such as offices, hotel or apartments will be discussed.
