Zusammenfassung:	A heat pump and a method of controlling a heat pump are provided. The heat pump may perform gas injection through a plurality of coolant injection circuits formed in a compressor, such as a scroll compressor, to increase a corresponding flow rate. The heat pump may control the plurality of coolant injection circuits based on one or more operation conditions by selecting an appropriate optimal middle pressure from a high-and-low pressure difference, a pressure ratio, and a compression ratio of the compressor to enhance cooling/heating performance.
