摘要： An air conditioning device includes a vapor injection cycle in which an operating speed of a compressor is adjusted to improve efficiency, and a method for controlling the device. The air conditioning device includes an inner heat-exchanger for exchanging heat between a first portion of refrigerant passing through a condenser and a second portion of the refrigerant branched from the first refrigerant, and an injection channel through which the second portion of the refrigerant is injected into the compressor. The inner heat exchanger includes an outer tube and an inner tube disposed inside the outer tube. The first portion of the refrigerant flows into the inner tube, while the second portion of the refrigerant flows into the outer tube. Thus, when a variation of air-conditioning load is small and an injection super-heating temperature is low, the device enables reduction of the compressor rotation speed to ensure high injection super-heating temperature.

摘要： A gas furnace according to an embodiment of the present disclosure includes: a mixer for mixing air and a fuel gas, which are introduced through an intake pipe and a manifold, respectively, to form a mixture; a mixing pipe through which the mixture, having passed through the mixer, flows; a burner assembly for producing a combustion gas by burning the mixture having passed through the mixing pipe; and heat exchangers through which the combustion gas flows, wherein the burner assembly includes: a plurality of burners, to which a flame produced during combustion of the mixture is anchored; a mixing chamber serving as a medium for delivering the mixture from the mixing pipe to the burners. Accordingly, a full premixing mechanism may be provided, and a mixing rate of the fuel gas and the air may be maximized, thereby greatly reducing nitrogen oxide emissions. Further, the burner assembly includes a uniform guide disposed inside the mixing chamber and allowing the mixture to be uniformly distributed to each of the plurality of burners, thereby preventing an increase in local flame temperature, and greatly reducing nitrogen oxide emissions.
