1. A refrigerant system comprising:
- an outdoor unit comprising;
an outdoor heat exchanger to heat-exchange a refrigerant and outdoor air with each other; and
a compressor to compress and to discharge the refrigerant;
a plurality of indoor units, each comprising;
an indoor heat exchanger to heat-exchange the refrigerant and indoor air with each other, wherein at least one of the indoor heat exchangers evaporates the refrigerant;
a high-pressure tube to guide the refrigerant discharged from the compressor to the plurality of indoor heat exchangers;
a low-pressure tube to guide the refrigerant evaporated in at least one of the indoor heat exchangers to the compressor;
a high-pressure branch tube branched from the high-pressure tube to guide the refrigerant in the high-pressure tube to at least one of the indoor heat exchangers;
a low-pressure branch tube branched from the low-pressure tube to guide the refrigerant in the at least one of the indoor heat exchangers to the low-pressure tube;
an indoor unit tube to connect the at least one of the indoor heat exchangers to both the high-pressure branch tube and the low-pressure branch tube; and
a high-pressure valve and a low-pressure valve mounted on the high-pressure branch tube and the low-pressure branch tube to selectively block the refrigerant flowing in the high-pressure branch tube and the low-pressure branch tube, respectively,wherein each of the high-pressure valve and the low-pressure valve comprises an electronic expansion valve to electronically control an opening degree thereof.

Abstract
A refrigerant system is provided. The refrigerant system may use an electronic expansion valve that electronically controls an opening degree thereof, as a high-pressure valve and a low-pressure valve to selectively block a high-pressure branch valve and a low-pressure branch valve. Accordingly, noise transmitted to an interior space may be minimized when the operation mode of the refrigerant system is switched. In addition, the structure of the refrigerant system may be simplified.
