Refrigeration System Including Evaporators Associated in Parallel

Abstract

The present invention belongs to the technological field of refrigeration systems and, more particularly refrigeration systems used in residential applications, for example, refrigeration appliances including at least two climate chambers at different temperatures. Problem to be solved: Conventionally, existing Refrigeration systems including evaporators connected in parallel require complex compressors including at least two suction paths, or alternatively functional complex arrangements unable to maintain independence between the individual evaporators. Troubleshooting: Disclosed is a refrigeration system including evaporators connected in parallel where each of said evaporators operates through a separate feeding principle, and that this aspect makes it possible, with the aid of a liquid accumulator and phase separator, maintaining the independence between the individual evaporators, besides the use of a compressor.

Description

FIELD OF THE INVENTION[0001]The invention relates to a refrigeration system including at least two evaporators connected in parallel, and more particularly, two evaporators even associated in series, has its outflows tied to the input path of an accumulator device liquids, which comprises one outflow capable of being fluidly connected to the suction path of a compressor.BACKGROUND OF THE INVENTION[0002]As is known to the skilled technicians in the subject, the current state of the art comprises a plurality of arrangements and constructions of refrigeration systems and, in particular, refrigeration systems including at least two evaporators. Of course, this refrigeration system category—with at least two evaporators—is due to the fact that the vast majority of refrigeration appliances, the conventional refrigerator comprises at least two refrigerated compartments operating in different temperature ranges such as, for example, refrigerators comprise a freezing chamber and a cooling ch...

AI Technical Summary

Benefits of technology

The invention is a refrigeration system with at least two evaporators in parallel. The system includes a compressor, condenser, switch device, expansion devices, and a liquid accumulator. The evaporators act at different pressure and temperature ranges. The system also includes a dry expansion evaporator and a flooded evaporator, with the outflow of the flooded evaporator connected to the liquid accumulator. The liquid accumulator acts as a siphon to prevent blockages. The compressor operates without lubricating liquids and may have additional special compartments. The technical effects of the invention include improved system efficiency, reduced emissions, and improved reliability.

Problems solved by technology

While this refrigeration system is, in theory, efficient, it is noted that the same has a drawback related to the operation period in which part of the refrigerant fluid is pumped from the evaporation low temperature evaporator (freezer) to the evaporator average evaporation temperature (refrigerator), after all, all of said refrigerant tends to migrate from the average evaporation temperature of the evaporator to the evaporator low evaporation temperature during operation of the system.

At the most, there is even any failure of unidirectional check valve result in compromising total system efficiency.
