摘要： A heat exchanger is provided in which high heat transfer efficiency has been attained by optimizing the slit array and setting an optimum range for the width of a slit and the spacing between slits. Slits 51 and 52 formed in front of the heat transfer coil 4 and slits 55 and 56 formed behind the heat transfer coil are arranged so as to provide a mutually different length among adjoining partitioned slits in the vertical direction, as well as a mutually different length between directly opposite partitioned slits in the horizontal direction. As a result, the position at which the slit is partitioned is staggered.

摘要： In a method and an apparatus for injecting mixed refrigerant into a refrigerant circuit comprising at least a compressor, a condenser, an expansion device and an evaporator which are connected to one another through a refrigerant pipe, the mixed refrigerant is intermittently injected from a refrigerant bomb at a predetermined position of a low pressure side of the refrigerant circuit while keeping the mixed refrigerant in a liquid state. The intermittent injection operation (amount) of the liquid refrigerant into the refrigerant circuit may be controlled on the basis of the degree of superheat of the mixed refrigerant in the refrigerant circuit.

摘要： A heat exchanger is provided in which high heat transfer efficiency has been attained by optimizing the slit array and setting an optimum range for the width of a slit and the spacing between slits. Slits 51 and 52 formed in front of the heat transfer coil 4 and slits 55 and 56 formed behind the heat transfer coil are arranged so as to provide a mutually different length among adjoining partitioned slits in the vertical direction, as well as a mutually different length between directly opposite partitioned slits in the horizontal direction. As a result, the position at which the slit is partitioned is staggered. The two slits 53 and 54 formed side by side between heat transfer coil 4 and heat transfer coil 4 are of the same length. For a 7 mm diameter heat transfer coil, the slit width relative to the diameter of the heat transfer coil ranges from 1.2/7 (approximately 0.17) to 2.0/7 (approximately 0.29), and the slit spacing relative to the diameter of the heat transfer coil ranges from 1.3/7 (approximately 0.18) to 3.5/7 (approximately 0.5).
