   Propane may be the most suitable for high temperature heat pumps. [73] Ammonia (R717) and carbon dioxide also have a low GWP. As of 2023 smaller CO 2 heat pumps are not widely available and research and development of them continues. [74] A 2024 report said that refrigerants with GWP are vulnerable to further international restrictions. [75]

   It also breaks the high temperature record for the 21st and 20th century. It said: “Phoenix Park has broken the highest 21st temperature record with 33C which is Ireland’s highest of 2022 so ...

   These heat pumps are also preferred for pool heating. Heat pumps typically only heat water to about 55 °C (131 °F) efficiently, whereas boilers typically operate at 65–95 °C (149–203 °F) [citation needed]. The size of radiators designed for the higher temperatures achieved by boilers may be too small for use with heat pumps, requiring ...

5. Heat pump and refrigeration cycle - Wikipedia

   en.wikipedia.org/wiki/Heat_pump_and...

   Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]

   Phoenix Park has broken the highest 21st temperature record with 33.0°C which is Ireland’s highest of 2022 so far and 12.8°C above normal. This is only 0.3°C below the all-time 135 year old ...

7. Absorption heat pump - Wikipedia

   For low-temperature heat sources of 15–25 °C, driven by a small amount of high-temperature heat sources (such as high-temperature steam or direct combustion), cold water at a temperature of 7–15 °C and hot water at a temperature above 47 °C can be prepared. 1.2, >1.5 when heating. [4]
