Japanese researchers unveil solar chemical heat pump system for buildings
The novel heat pump concept combines solar energy with chemical storage and reportedly consume 75% less electricity than conventional heat pumps. The system relies on a battery and a heat storage tank that can be used either separately or simultaneously, depending on the outdoor conditions.
Combining residential air heat pumps with air-geothermal heat exchangers
Researchers in Italy have found that combining residential air heat pumps with air-geothermal heat exchangers may reduce power consumption by up to 30%. They tested the proposed combination using Matlab in a passive single-family building located in Valtellina, northern Italy.
Researchers propose new models for heat pump load forecasting in energy communities
Novel research from Germany and the USA has analyzed the impact of heat pump (HP) integration on the ability of day-ahead load forecasting in energy communities. Using different models, the scientists have also investigated whether HP loads should be forecasted separately from the rest of the household or both together.
US startup debuts wall-mountable residential heat pump
US-based Quilt has unveiled a residential heat pump with a coefficient of performance (COP) of up to 4 and noise levels of 27 dBA to 47 dBA. The startup recently raised $33 million (€30 million) from a group of investors.
M-Tec presents residential air-source heat pump
The Austrian manufacturer said its new heat pump can achieve a seasonal coefficient of performance of up to 4.7 and flow temperatures of up to 75 C. It is available with sizes ranging from 2 kW to 7 kW.
Midea unveils outdoor residential heat pump
Midea says its new outdoor residential Evox G3 Heat Pump ranges in size from 1.5 tons to 5 tons, with a coefficient of performance of 1.8. It features enhanced vapor injection technology and uses A2L as the refrigerant.
Online tool shows CO2 savings for UK homeowners with heat pumps
British Gas has developed the Carbon Cruncher tool for the UK market. It contextualizes emissions by comparing them to other emitters.
Ideal Heating launches new air source heat pump series
The UK-based manufacturer said the new Ecomod 290HT products have a size ranging from 15 kW to 50 kW and a coefficent of performance of up to 4.9. The systems can reportedly achieve a flow temperature of 75 C.
Solar-assisted thermochemical heat pump based on caustic soda, water
Researchers in China have designed a two-stage, solar-assisted thermochemical heat pump system that uses caustic soda and water as a working pair. The system is reportedly able to achieve an energy storage density of 363 kWh/m3 and is considered by its creators an ideal solution for residential buildings with limited space.
Norwegian startup unveils CO2 water-to-water heat pump
Tequs said its new plug-and-play heat pump can deliver up to 90 C of heat for space heating, air conditioning, and domestic hot water. The new product is available in eight versions with capacity ranging from 17 kW to 268 kW.
