Abstract
A distributor for feeding the liquid-vapor mixture of refrigerant from the expansion valve to the core elements of an evaporator of an air conditioning system to provide equal distribution of both the liquid and vapor components. The distributor involves either a single header with separate orifices for the liquid and vapor in each core element or a pair of distribution headers to carry the separated component phases from a separator with an orifice for each phase in each core element where the phases would be recombined to pass through the core elements to a common outlet.
Claims14
An evaporator for an air conditioning system receiving a liquid-vapor mixture of refrigerant from an expansion valve and comprising a plurality of core elements arranged in parallel, each core element formed from a pair of oppositely dished plates joined at the edges and defining an inlet, an outlet and a core cavity connecting the inlet and outlet, the improvement comprising at least one inlet header defined by the inlet openings of the core elements receiving the liquid-vapor refrigerant mixture, an outlet header defined by the outlet openings, a liquid supply orifice from said inlet header to the core cavity of each core element, and a separate vapor supply orifice from said inlet header to the core cavity of each core element to provide an equal distribution of refrigerant liquid and vapor from said header to each of said core elements.
