Abstract: An air conditioner is provided that may include an outdoor unit provided with a compressor; a plurality of indoor units connected to the outdoor unit, each having an indoor heat exchanger, and each disposed in a different space; a low pressure pipe that connects the indoor heat exchanger and the compressor and in which low pressure gaseous refrigerant flows; a switching device provided with a low pressure valve disposed between the indoor heat exchanger and the low pressure pipe; an indoor temperature sensor that measures a temperature of a space in which an indoor unit of the respective indoor unit is disposed; and a controller that is electrically connected to the indoor temperature sensor and adjusts an opening degree of the low pressure valve. The controller may adjust the opening degree of the low pressure valve based on a difference between a value measured by the indoor temperature sensor and a previously input set temperature.

Abstract: An air conditioner may include a controller; a compressor; an outdoor heat exchanger; a plurality of indoor heat exchangers; a switching valve that selectively guides a refrigerant discharged from the compressor to the outdoor heat exchanger or the plurality of indoor heat exchangers; high pressure pipes that connect the switching valve and the plurality of indoor heat exchangers; high pressure valves installed in the high pressure pipes; low pressure pipes that connect an inlet of the compressor and the high pressure pipes. low pressure valves installed in the low pressure pipes; indoor pipes, which are opposite to the high pressure pipes with respect to the plurality of indoor heat exchangers and connected to the plurality of indoor heat exchangers; indoor expansion valves installed in the indoor pipes; a liquid pipe that connects the outdoor heat exchanger and the indoor pipes; and an outdoor expansion valve installed in the liquid pipe.

Abstract: An air conditioner may include a controller; a compressor that compresses a refrigerant; an outdoor heat exchanger through which the refrigerant discharged from the compressor flows; a plurality of expansion valves that expands the refrigerant passed through the outdoor heat exchanger; a plurality of indoor heat exchangers through which the refrigerant passed through the plurality of expansion valves flows; a plurality of connection pipes that connects the plurality of indoor heat exchangers and the compressor; and a plurality of variable valves installed in the plurality of connection pipes. An opening degree of each of the plurality of variable valves may be adjustable via the controller.

Abstract: Provided are encoded polymeric microparticles and a multiplexed bioassay using the encoded polymeric microparticles. Each of the encoded polymeric microparticles includes an encoded polymeric microparticle core and a silica shell surrounding the microparticle core. Further provided is a method for producing encoded polymeric microparticles. The method includes: mixing a photocurable material with a linker having a functional group polymerizable with the photocurable material and an alkoxysilyl group; applying patterned energy to cure the mixture, followed by encoding to obtain encoded polymeric microparticle cores; and treating the encoded polymeric microparticle cores with a silica precursor to form a silica shell on each encoded polymeric microparticle core.

Abstract: A technique related with a lithography system is disclosed. The lithography system includes at least one target object disposed on a substrate, a processor configured to process an image of the target object to determine an optical pattern for a coating layer of the target object, and an exposure apparatus configured to provide light having the optical pattern determined by the processor to the substrate.
