Grabbing Attention: Ejector Technology for Passenger Vehicles

Ejector It’s one thing to grab someone’s attention. It’s quite another thing to bait and switch. As a blogger, I get quite a bit of PR email. Today, one came from DENSO corporation with a file attached which was named "DENSO Develops ejector technology for passenger vehicles."

My brain said "CRIKEY! What’s this about?". I opened it and found out that it is some kind of new-fangled air conditioning technology.


By using an ejector that rapidly injects and expands high-pressure refrigerant, the energy that previously was lost in the expansion valve is converted to pressure energy and reused, thus boosting energy efficiency*2. As a result, high cooling and refrigeration performances are both achieved even when the cooler box is used.

“An ejector system can drastically improve the energy efficiency in the refrigeration cycle, and we are now working to develop a system specifically for car air conditioning systems,” said Hikaru Sugi, managing officer in charge of DENSO’s Thermal System Business Group.

Unless you are really into the whole air conditioner technology groove, this is total boredom.

Really, this is just a PR typo, but doesn’t it remind you of some of the marketing and advertising crap you see every day? Don’t do this type of thing in your advertising.

Another example is the stupid travel site emails I get every day. Southwest Airlines sent one the other day which promised Denver-Austin for $79 each way. Not on the dates I wanted, and only on about 2 dates between now and Christmas. Sheesh.

How have the marketers been fooling you?
