Carrier
Carrier has introduced a new line of high temperature and very high temperature heat pumps for use in industrial, commercial and public buildings and district heating. Designed to reduce both carbon emissions and energy costs, the new line consists of AquaForceand AquaSnap air and water source heat pumps with varying capacities from 30 to 735 kW and water temperatures from 82°C to 120°C with low GWP HFO refrigerants. The high temperatures enable the heat pumps to replace fossil fuel boilers in heating applications such as apartment blocks and residential estates, commercial buildings, food manufacturing, industrial drying, biogas production and chemical plants. In addition to harnessing heat from ambient air and the
ground, the heat pumps capture wasted heat from a wide range of sources, including data centres, leisure facilities, hotels and restaurants, process water, fl ue gases and sewage systems. Heat collected can be used for comfort heating and domestic hot water production in large buildings and facilities. The heat pumps can also be applied in industrial applications, and in district and local heating networks where high temperatures or very high temperatures are required. “The expansion of the AquaForce and AquaSnap ranges is a crucial step in delivering our commitment to support the European Green Deal and helping decarbonise the heating segment in Europe,” said Raff aele D’Alvise, Marketing and Communications Director, Europe Commercial HVAC, Carrier. “With a focus on high temperature, performance, reliability and effi ciency, these heat pumps are an excellent solution for customers looking to reduce their carbon footprint and contribute to a more sustainable future by replacing or integrating with fossil fuel generators in hybrid systems.” The units come ready to connect to Abound, Carrier’s cloud- based digital platform that enables real-time, intelligent outcome-based results that make buildings more effi cient and responsive. To minimise operating costs, users can opt for one of Carrier’s BluEdgeservice options to keep heat pumps operating at peak performance and effi ciency throughout their lifecycle. This leads to predictive maintenance rather than preventive maintenance, saving time and money.

Nuaire
Nuaire has expanded its Boxed Packaged Solution (BPS) range of Air Handling Units (AHUs) with the the BPS-ECO-HP; a unit with integrated heat pump charged with R32 refrigerant. The BPS-ECO-HP uses 20% less refrigerant than existing market competitors still opting for R410a. By using R32, the most effi cient and lowest-Global Warming Potential (GWP) refrigerant on the market for an AHU, the BPS-ECO-HP is more effi cient when carrying heat and has a lower impact on the environment. The R32 refrigerant has a GWP of 675, 30% lower than that of systems available on the market right now. By integrating the heat pump, the need for on-site refrigerant installation works is eliminated – creating a system that is quicker and easier to specify, install and maintain, while still incorporating all of the classic BPS features, such as its hydrophobic roof, high-classifi cation levels, skid system for ease of maintenance, and Nuaire ‘plug and play’ Ecosmart controls as standard.
The heat pump system is installed within the thermal wheel allowing for a very effi cient heat recovery system. The incorporated dual compressor operation features an automatic defrost control strategy to ensure heat recovery is not lost in the event of one compressor failing. When the build-up of frost in the exhaust coil reaches a limit, the dual system will automatically respond and start warming up the second system to ensure continuous ventilation and peace of mind.
