Coefficients of Performance (CoP) when compared to HFC-134a and HCFC-22.

A study on refrigerants used in geothermal heat pumps in a 14-storey residential building in Iran, has shown that ammonia and hydrocarbon produce significantly better Coefficients of Performance (CoP) when compared to HFC-134a and HCFC-22.
The researchers monitored performance of a horizontal closed-loop ground heat pump with a cooling load of 915 kW (260 TR) in the town of Qazvin. Ammonia came out as the most energy efficiency refrigerant with a CoP of 4.663. Hydrocarbon, n-butane’s COP was 4.606. Overall the natural refrigerants had COP’s 4.5%-5.8% higher than HFC134a. Similar results were obtained for open-loop and vertical closed-loop ground heat exchangers.
The study also found ammonia and n-butane to have a reduced initial system cost compared to HCFC-22 and HFC-134a in terms of initial system cost.

Have your say!

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.

Reported energy savings of over 60% compared to previous system.

In 2013, Walgreens installed it’s first net-zero energy store in Evanston, Illinois. The store has a transcritical CO2 and geothermal heat pump system, which uses ground water to heat and cool the store, with reported energy savings of over 60%. Its Empire State Building store uses a split mini-rack system that employs a zero-ozone depleting refrigerant.
