Abstract
The present invention relates to the refrigerant system in which the refrigerant amount stored in the accumulator may be adjusted by the super cooling adjustment unit according to the indoor conditioning load. Therefore, according to the present invention, the flow refrigerant amount on the refrigerant cycle may be optimally adjusted according to the indoor conditioning load, and there is an advantage that the operation efficiency may be more improved.
Claims21
A refrigerant system, comprising:
- a compressor which compresses a refrigerant;
- a condenser which condenses the refrigerant discharged from the compressor;
- an expanding unit which expands the refrigerant passed through the condenser,
- an evaporator which evaporates the refrigerant passed through the expanding unit;
- a main refrigerant pipe which forms a refrigerant cycle by connecting the compressor, the condenser, the expanding unit and the evaporator;
- an accumulator filtering a liquid refrigerant among refrigerants flowing into the compressor;
- a super cooler in which a portion of the refrigerants is distributed to super cool the refrigerant of the main refrigerant pipe, the super cooler configured to guide to introduce the portion into the accumulator;
- a super cooling adjustment unit which adjusts a portion of refrigerant amount passed through the super cooler;
- and
- a control unit which controls refrigerant amount stored in the accumulator by the super cooling adjustment unit so that flow refrigerant amount on the refrigerant cycle is optimized according to operation states;
- and
A control method of a refrigerant system comprising a compressor, a condenser, an expanding unit and an evaporator, the refrigerant system includes a refrigerant cycle which performs the conversion of cooling or heating operations, a refrigerant pipe which guides the refrigerant circulating the refrigerant cycle, and an accumulator which filters a liquid refrigerant of the refrigerants introduced into the compressor, the control method comprising:
- detecting a discharge pressure of the compressor;
- detecting the refrigerant amount stored in the accumulator;
- comparing the detected discharge pressure or refrigerant amount with a predetermined reference value;
- and
- adjusting refrigerant amount introduced into the accumulator, among refrigerants circulating the refrigerant pipe, based on a compared result.
