We broke new ground with this project: Air-water heat pumps not only had to be deployed reliably and cost-effectively for heating and hot water, the devices' heat pump functions also had to provide cold water for the cold water climate-control system in order to cool down the building's attractive glass facade. Additionally, an exterior pool had to be heated reliably and efficiently with a heat pump.

Challenge

The modern building has large glass surfaces. Without adequate technology, however, the building gets uncomfortably warm on sunny days. Therefore, from the very start, the customer wanted the building technology to be able to heat in the winter and provide comfortable cool temperatures in the summer. The customer also stressed the need to minimize CO2 emissions by using renewable energy sources (including solar and battery buffers).

Solutions & Tech Applied

Because the heat pumps used not only to heat but also to cool, no additional units were needed. And thanks to the heat pump technology (renewable energy) and the photovoltaic system we employed, the amount of electricity that needs to be purchased is also reduced. 

Use of 2x Super Quiet T-CAP split heat pumps in conjunction with cascade controllers provide heating/cooling/hot water. A cooling and heating buffer plus a domestic hot water tank were also installed for each one. Another T-CAP mono bloc auxiliary is used to help heat the pool. Heat distribution: Underfloor convectors and ceiling cassettes are supplied by the heat pump at 35/28 °C in heating mode and 7/12 °C in cooling mode.
