PV-driven heating, cooling system for supermarkets
Scientists in China have developed a novel PV-powered cooling and heating system that combines a water-cooled gas cooler and an air-cooled gas cooler. The system went through a series of simulations and showed it can potentially achieve a coefficient of performance of up to 7.34.
Carrier introduces residential R32 air-to-water heat pump
The new product features a coefficient of performance of 4.9 and sound levels of 52–56 db(A).
Standalone liquid air energy storage system for power, heating, cooling supply
Korean scientists have designed a liquid air energy storage (LAES) technology that reportedly overcomes the major limitation of LAES systems – their relatively low round-trip efficiency. The novel system enhances efficiency by increasing power output through the generation of thermal energy using natural gas as the external fuel during energy release.
Aira launches residential heat pump with minimalist design
The Sweden-based heat pump provider said its new product is one of the slimmest and most compact system available on the market to date.
Grant launches air source heat pump for residential applications
The novel propane heat pump has a coefficient of performance of up to 4.9 and can reportedly achieve a flow temperature of up to 55 C.
Johnson Controls releases new residential heat pump series
The new heat pumps use R-454B as a refrigerant and are specifically designed to be matched with Johnson Controls’ residential gas furnaces. Their size ranges from 1.5 tons to 5 tons and their coefficient of performance (COP) spans between 3.24 and 3.40, according to the manufacturer.
Daikin presents modular water-to-water heat pumps
