Heat Pumps

Scientists in India have conducted an extensive review of all direct expansion solar heat pump technology in an effort to broaden its residential adoption. Such system can psroduce hot water from 15 C to 60 C at an average coefficient of performance of 1.5 to 4.5.

The new products utilize propane refrigerant and have a seasonal coefficient of performance of over 5. According to the manufacturer, it can achieve a flow temperature of 75 C, even when it is -15 C outside.

Half year data from UK certification body MCS reveal a step change in the number of heat pump installations in 2024, as well as a record breaking first six months for battery storage installations. At the current rate, the annual heat pump installation record will be broken by the end of 2024

The Austrian manufacturer said its new heat pump is an ideal solution for industrial and district heating market segments. The system features an advanced rotor system, exploiting diffusion bonding technology, which reportedly enables higher temperature lifts, and greater manufacturability due to fewer components.

Researchers in Germany have proposed to use a machine learning technique known as reinforcement learning to optimize heat pump performance and reduce electricity consumption in apartment complexes. Their simulation showed that significant savings can be achieved without compromising comfort levels.

The UK-based manufacturer said its new air-to-water Auriga heat pump features a seasonal coefficient of performance (SCOP) ranging from 3.33 to 4.83 and noise levels of 43 dBA to 65 dBA.

The Luxembourg-based manufacturer said the new product can reach flow temperatures of up to 72 C and achieve a seasonal coefficient of performance (SCOP) of up to 5.7.

The provincial government of Prince Edward Island, Canada, has signed an agreement with the Canadian federal government to implement the Oil to Heat Pump Affordability (OHPA) program. The scheme offers grants to low- and medium-income households to install heat pumps and has nationally delivered more than 7,000 units to date.

Researchers in Italy have designed a water-source heat pump system intended for generating cooling, heating and domestic hot water in social housing stock built during the 1970s–1990s. The novel concept integrates photovoltaic-thermal energy with thermal storage and promises a seasonal coefficient of performance of 5.

The Thermafit Air-Source Modular Multipipe heat pump uses R-454B as the refrigerant and has a size of 30 tons. The manufacturer said the system act as a chiller to cool the building, as a heat pump to heat the building, or as a heat recovery unit to deliver simultaneous heating and cooling.
