Abstract

Official abstract text for this publication.

A refrigerant system includes an outdoor unit and a plurality of indoor units. The outdoor unit has a compressor and a plurality of heat exchangers and each indoor unit has a heat exchanger. A detector detects pressures at an inflow side and a discharge side of the compressor, and a controller controls a direction of refrigerant flow for the heat exchangers of the outdoor unit. This may involve changing the refrigerant flow direction for at least one of the heat exchanger of the outdoor unit based on the detected pressures.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for controlling a refrigeration system, comprising: confirming a first operation state of first and second outdoor heat exchangers of an outdoor unit; initializing an elapsed time; detecting rpm of an outdoor fan; detecting an inflow side pressure and a discharge side pressure of a compressor if the detected rpm of the outdoor fan is below a reference rpm; determining whether the elapsed time corresponds to a reference time if the discharge…
