heat pumps

A European research team proposed a new air-source heat pump sizing approach that utilizes long-term climate data and adjusts system operation based on actual local climate conditions. The sizing algorithm incorporates peak heat demand, unitary final energy demand, and seasonal heat demand across different house sizes.

New research from Germany shows that identifying the cheapest residential heating source remains challenging, as the final results depend on the assumptions made and energy prices. The scientists, however, demonstrated that air-water heat pumps and gas heating systems are currently the most cost-effective solutions.

Researchers in Denmark have found that using a large-scale air-to-water heat pump in solar district heating may significantly reduce its levelized cost of heat. The proposed system configuration was simulated for an existing district heating plant in Denmark and was found to improve the flexibility of the system in response to energy prices.

Futraheat has developed a 300 kW/1.5 MW heat pump that can reportedly deliver steam up to 130 C and reach a coefficient of performance of 6.2. The first prototype was deployed at a brewery in Sussex.

New research from Germany shows that the optimal size of residential heat pumps in retrofit buildings can be achieved without factoring in their potential connection to a PV system and related control strategies. An optimal sizing strategy, by contrast, should not neglect electricity price assumptions.

The U.S. heating specialist said its Vilter VQ95 heat pump is an ideal solution for district heating and industrial processes. It has a heating capacity of 1 MW to 5 MW per skid and can reportedly provide a temperature of up to 95 C.

The novel heat pump concept should enable ready-to-use energy storage even in already existing installations. It features capabilities that easily detect self-consumption of PV energy, maximizing the amount of energy that can be produced and consumed on-site

Portugal-based Effizency, a developer of sales software for solar PV and heat pump solution providers, has launched a new web-based simulator module that its customers can use to deliver initial price quotes and savings estimates to potential buyers.

Researchers in Denmark built a magnetocaloric heat pump prototype for heating purposes in residential buildings. Although more work is needed to bring the system closer to commercial maturity, it can reportedly achieve a 36.9 % heating power improvement with measurement feedback control.

Western New York Energy says it will install an industrial steam-generating heat pump at its ethanol plant in Medina, New York, with a maximum output temperature of 215 C and a coefficient of performance of 2.7.
