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...
After intense seven month, the test unit has been commissioned with little delay, runs 24/7 and is already delivering the much expected results. The unit is installed in a 5 m long 2.2 m wide and 2.5 m high trailer.
Klimastiftung Schweiz supports HyWin in designing and building a test unit, which allows to test the HyWin concept under realistic conditions.
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...
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
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.
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.
