QUESTION: My old central air conditioner still works , but I wonder if I should replace it with a super-efficient one. How much can I expect to save on my electric bills? Are the new natural gas cooling units efficient? ANSWER: Your old air conditioner probably has a SEER (efficiency ratio) of about or 7. This ammonia is then decompressed and evaporated around a circulating water system, cooling the water.
Air conditioners that use gas heat to create compression are called absorption units.
There is a company called Robur that manufactures these units for residential use. Residential air conditioners are small, direct-fired absorption chillers. An absorption chiller uses a refrigerant, absorbent and heat to create a cooling effect. Over the last decade, manufacturers made significant advances in developing and producing a new generation of natural gas refrigeration, cooling, and humidity control equipment. While there are additional fans, valves, sensors, and other components to your air conditioner , these four components are fundamentally the main components.
When comparing natural gas air conditioning units, you will want to look at the seasonal energy efficiency ratio (SEER) rating.
