Flooded evaporator in small refrigeration- and heat pump systems.

Number: pap. ID: 913

Author(s) : ERICSSON S.

Summary

This paper describes tests of a system that obtain flooded evaporation in small refrigeration and heat pump systems. With flooded evaporation the heat transfer in the evaporator can be improved, which increases the evaporation temperature as well as the cooling and heating coefficients of the system. (Prof Dr.-Ing. Michael Kauffeld 30%) (Rizzvi Z and Dr Peter Heggs 16-48%) The system is based on three main newly developed system components: a) ?An automatic self-acting bubble expansion valve to secure a bubble free condensate; b) ?New technique to recirculate compressor oil from evaporator/accumulator; c) ?New strategy to recover the pressure drop losses by circulating the cold refrigerant several times between the condenser and the evaporator. Energy savings with this method has been evaluated and an improvement of 10% compared with a standard system using superheated gas strategy has been verified.
