With a very silent operation at 61 dB, the heat pump is available in 5kW, 7kW and 9 kW models, which can then be combined into two units to achieve a total combined capacity of 18 kW. It also used not just for heating but cooling as well.
Between 2012-2013, Chinese manufacturer Tianjin Hi-Tech recorded energy savings of 49% and 36% in two CO2 HP heat pumps installed in railway stations in Dandong and Tongliao citites. The systems provide hot water, space heating and air conditioning for the stations for all-weather purposes and are able to maintain a higher Coefficient of Performance than that of a conventional HCFC or HFC-based system, even at temperatures of down to -25°C.
GEA RedAstrum is the new series of standard ammonia heat pumps designed for an increasing demand of efficient heating solutions. This new generation consists of four heat pump models based on the GEA Grasso M screw compressors H, L, M, N newly developed for 52 bar applications. The GEA RedAstrum transfers heat to a heating carrier at temperature levels between 55 to 80 °C which can be utilized in any industrial processes or fed into a district heating network.
Sanyo sells hydrocarbon domestic refrigerators and CO2 commercial refrigerators. The company also sells CO2 showcases and heat pumps, and CO2 compressors for vending machines. The company reports that since 2005 almost all beverage companies in Japan had purchased vending machines from them with natural refrigerants (either CO2 or HC). There are over 60,000 CO2 vending machines in the Japanese market today. Sanyo also produces compressors for “hot and cold” CO2 vending machines that provide both hot and cold beverages in one machine. As well, the company produces CO2 heat pumps and water heaters under the label “EcoCute”. Industry-wide, EcoCute has a market volume of over 1 million units since 2001. It is reported that up to 500,000 EcoCute units are produced annually, representing the largest market for CO2 refrigerants in the world.

ATMO Intelligence, the Market Development division of shecco invites air-conditioning and refrigeration stakeholders to participate in a survey that assesses the F-Gas Regulation, sector by sector, while also looking into what should be included in an upcoming revision of the regulation.
Respondents select the sectors they are active in and complete a custom survey based on their interests. “With these results, we will produce a comprehensive report that will be shared with policymakers across the EU to drive more progressive change, particularly in terms of refrigerants and getting rid of harmful gases in all sectors – from transport refrigeration to domestic air conditioning,” said Ilana Koegelenberg, Market Development Manager at shecco.
Once completed, the report will be freely available for download.The survey should take around 15-20 minutes.
The air to water heat pump uses waste heat and air and brine heat sources. It produces a heating water flow temperature of 60 °C. It has a heating output of up to 74.6 kW and a cooling capacity of 44,8kW.
