Pumpless refrigeration

The phase-out of ozone-depleting synthetic refrigerants in refrigeration systems becomes increasingly commonplace. Carbon dioxide, CO is one of the natural. An absorption refrigeration system using a two or more substance solution to achieve refrigeration that eliminates the need for a pump. Other practical attributes of this pumpless loop are small liquid inventory requirements and absence of the incipient boiling temperature drop.

Ejector refrigeration is considered as one of the three main ways of refrigeration and air-conditioning to utilize lowgrade energy. Use of pump-less technology to .
