Abstract

Refrigeration air conditioning equipment is one of the common household appliances made in large numbers to attain reliable design, quality rich product with cost efficiency. Capillary is the key component, in which the design is empirical based on air flows over heat exchangers of condenser, evaporator, compressor and refrigerant mass flow. Though there are theoretical models, it is very difficult to get an optimum design. Practically, large manufacturers carefully optimize the capillary designs. In this study, the procedure for capillary design and selection is presented to obtain designed pressure drop between condenser and evaporator and to fulfill the role of metering in the air conditioner system.
