Tequs said its new plug-and-play heat pump can provide up to 90C heat for space heating, air conditioning and domestic hot water. The new product is available in eight versions with power ranging from 17 kW to 268 kW.
Norway-based Tequs launched a new water-to-water, plug-and-play CO2 heat pump for residential and commercial applications.
“Our new one heat pumps are modular and can be used in parallel to achieve higher capacities,” says company CEO Joakim Søgård. pv magazine. “The units are pre-filled with CO2 and oil and are ready to use. The machines are very user-friendly thanks to a large touchscreen with a user-friendly user interface for service and maintenance.”
According to the manufacturer, the system design allows for simultaneous heating and cooling when both sides are used. It is said to be able to handle a return temperature of up to 50C, or up to 60C if a hydronic kit is used.
“The products are particularly distinctive in that they can provide heat up to 90°C for space heating, air conditioning and domestic hot water, while being able to handle the high return temperatures required when retrofitting a heating system designed for fossil fuel heating,” says Søgård . “This is far above what others have done before us. In return, we can accept up to 50°C while maintaining a good coefficient of performance (COP).”
Using the heat pumps R744 (CO2) as a refrigerant and are available in eight versions with capacities ranging from 17 kW to 268 kW.
The smallest product, called TCHP 17, measures 1,462 mm x 690 mm x 1,913 mm and has a voltage of 400 V. It is said to offer a heating capacity of 18 kW and a cooling capacity of 17 kW. The COP for heating is 5.0 and for cooling 4.4.
The largest system, labeled TCHP 268, has a size of 2,357 mm x 690 mm x 1,913 mm and a voltage of 400 V. The heating capacity is 268 kW and the cooling capacity is 267 kW. As for the COP for heating and cooling, the manufacturer said that these values are 5.4 and 4.5 respectively.
According to the manufacturer, the new series of heat pumps is particularly suitable for hotels, office buildings, residential complexes, swimming pools and industrial buildings.
“Our goal was to develop a range of heat pumps that are particularly suitable for a heating system where a gas boiler needs to be replaced,” explains Søgård. “We started the project in 2020 and have been active for four years now. The product has gone through many different prototype phases, both in the laboratory and in the field, and was recently present at the Norwegian Technical Annual Conference for Refrigeration.”
