The Canadian Climate Institute has released a report that explains how to unlock lower-cost heating and cooling in Canada. It outlines barriers to adoption and makes recommendations to streamline the loan and grant application process.

Researchers from the Netherlands have assessed the potential integration of heat pumps, electric vehicles, and PV systems into distribution grids. They have discovered that suburban grids could face a higher risk of overload. By using actual data from Dutch distribution grid operators, they believe their methodology could be applied to study energy systems in other nations.

A research group led by the Technical University of Denmark has analyzed how booster heat pumps may effectively improve the performance of ultra-low temperature district heating networks in colder climates and has found that the refrigerant change plays a crucial role. They also said that powering these heat pumps with renewables may also better integrate clean sources in energy systems.

Swedish manufacturer Qvantum has announced plans to set up a heat pump factory in Hungary. The new facility is expected to have an annual production capacity of 1 million heat pumps.

Octopus Energy has developed new residential heat pumps, with plans to initially market a 6 kW version, followed by larger models in the near future. The UK-based company makes the heat pumps at its facility in Craigavon, Northern Ireland.

A British research group has aggregated information from seven field studies on heat pumps from around the world and has found air-source devices have an average coefficient of performance (COP) of 2.74 when temperatures are above −10 C. Below that, COP is between 1.5 and 2.

Johnson Controls-Hitachi Air Conditioning has developed a residential dual fuel heat pump system that combines an air source heat pump and a gas furnace. The manufacturer says the furnace is designed to ensure there is no compromise in heating performance, even when temperatures are extremely low.

Worcester Bosch’s new residential heat pumps are available in several versions, with output ranging from 4 kW to 30 KW. It says the new products can be cascaded up to six units.

Scientists from South Korea have developed a heat pump optimization technique that controls the secondary refrigerant flow. The proposed technology offers the advantage of bypassing the need to control the compressor of the heat pump, which is a function that is commonly not available in commercial devices.

Scientists in India have combined a solar-assisted heat pump with a humidification-dehumidification and vapor compression refrigeration (HDH-VCR) cycle to generate heat and cooling. The system is reportedly able to generate up to 5.5 l per hour (LPH) of fresh water while achieving an ‘enhanced’ coefficient of performance.
