Employment of multiphase (two-phase) thermal pump in absorption refrigeration system.

Author(s) : CHAMI F. A.

Summary

Absorption refrigeration systems have advantages over vapour compression refrigeration systems: they use heat as source of energy, have no moving parts (except strong solution pump) and therefore quiet in operation and minimum maintenance requirement; the absence of inertia forces due to imbalances of masses makes it possible to construct absorption refrigeration systems of many thousand kilowatt refrigeration capacity per unit. Total elimination of moving parts in absorption refrigeration system by substituting the strong solution pump with multi-phase thermal pump is proposed. The pump utilizes steam from the generator (boiler) and strong solution from absorber to create the head to raise the strong solution from the absorber to the generator. The proposal is a result of experiments conducted on multi-phase thermal pump constructed and tested using steam and water.
