The present invention provides a cooling and heating vapor injection system which comprises: a compressor compressing a refrigerant to circulate; a first branch unit where the compressed refrigerant is introduced to be branched; a first refrigerant line, where a condenser and a first expansion valve are arranged, branched from the first branch unit to allow the refrigerant to flow; a gas-liquid separator allowing the refrigerant passing the first refrigerant line or the second refrigerant line; and a second branch unit where the refrigerant passing the gas-liquid separator is introduced. The gas-liquid separator allows the liquid refrigerant to flow to the second branch unit and allows the gaseous liquid to flow to the compressor.
