摘要： A refrigeration cycle device (100) where a combustible refrigerant circulates includes a bypass pipe (5) that is connected so that part of the refrigerant that flows through a circulation pipe extending from a condenser (2) to a flow control valve (3) bypasses the flow control valve (3) and an evaporator (4); a bypass flow control valve (6) that controls the amount of the refrigerant flowing through the bypass pipe (5); a heat exchanger (7) that allows heat exchange between the refrigerant that flows through the bypass pipe (5) after flowing out of the bypass flow control valve (6) and the refrigerant that flows through the circulation pipe after flowing out of the condenser (2); and a subcooling degree sensor (T73) that detects the subcooling degree of the refrigerant at the inlet of the flow control valve (3). At least either the flow control valve (3) or the bypass flow control valve (6) is controlled so that the subcooling degree of the refrigerant at the inlet of the flow control valve (3) is equal to or greater than or a predetermined value.

摘要： SE PRESENTA UN ACUMULADOR QUE ES CAPAZ DE EVITAR UN AUMENTO EXCESIVO DE LA VELOCIDAD DE FLUJO DE UN REFRIGERANTE LIQUIDO QUE ES DESCARGADO DESDE EL ACUMULADOR, REDUCIENDO LA CANTIDAD DE ACEITE REFRIGERANTE DE LA MAQUINA QUE SE ACUMULA EN EL ACUMULADOR Y MANTENIENDO UNA CANTIDAD REQUERIDA DE ACEITE REFRIGERANTE DE LA MAQUINA EN UN COMPRESOR. EL LIQUIDO Y UN GAS QUE CIRCULA EN UN CIRCUITO DE REFRIGERACION Y DE ACONDICIONAMIENTO DE AIRE SE INTRODUCEN DENTRO DE UN PRIMER ESPACIO (1) MEDIANTE UN TUBO DE SUCCION (3), Y EL REFRIGERANTE GASEOSO ES DESCARGADO A UN CIRCUITO DE REFRIGERACION Y ACONDICIONAMIENTO DE AIRE A TRAVES DE UN TUBO DE CONDUCCION DEL GAS (4), DE UN SEGUNDO ESPACIO (2) Y DE UN TUBO DE DESCARGA (5). MAS AUN, UNOS MEDIOS DE MANTENIMIENTO DEL NIVEL DEL LIQUIDO (7 Y 8) EVITAN LA ELEVACION DE LA ALTURA DEL LIQUIDO ACUMULADO INTRODUCIDO DENTRO DEL PRIMER ESPACIO (1). CUANDO LA ALTURA NO DEBE DE SER MENOR DE UNA ALTURA PREDETERMINADA, EL MEDIO DE COMUNICACION DEL GAS (4) MUEVE EL LIQUIDO EN EL PRIMER ESPACIO DESDE EL PRIMER ESPACIO (1) AL SEGUNDO ESPACIO (2). ADEMAS, UN MEDIO DE RETORNO (6) DESCARGA EL ACEITE REFRIGERANTE DE LA MAQUINA ACUMULADO EN EL PRIMER ESPACIO (1) EN EL CIRCUITO DE REFRIGERACION Y ACONDICIONAMIENTO DE AIRE.

摘要： A heat exchanger mounted in an air condition is constructed such that at least one row of heat conduction pipe groups are arranged so as to obstruct an air passage. Each heat conduction pipe groups is constructed such that a plurality of heat conduction pipes 22 are arranged in parallel with each other and a fine wire 23 made of a metallic material having excellent heat conductivity is spirally wound around each adjacent heat conduction pipes 22. Thus, performances of the heat exchanger can be improved without a possibility that the air conditioner is designed with larger dimensions. In addition, the heat exchanger includes a plurality of heat conduction pipes 39 arranged in the form of at least one row with a constant distance between adjacent ones and a plurality of twisted wires 40. The twisted wires 40 are arranged so as to alternately come in contact with one side and opposite side of each heat conduction pipe 39 extending at a right angle relative to the row direction of each heat conduction pipe 39, and moreover, alternately come in contact with one side and opposite other side of each heat conduction pipe 39 extending in the longitudinal direction. With this construction, high heat conductivity can be realized, and an occurrence of clogging with dew droplets can be prevented while maintaining a heat conduction area.

摘要： A control device for refrigeration cycle having a compressor 1, a condenser 3, an electrically operated expansion valve 5, an evaporator 6 connected in series, and a by-pass 18 extending from an inlet or an outlet or both of the expansion valve up to an inlet of the compressor through a capillary tube; a first temperature sensor 13 senses a temperature of a cooling medium at the inlet of the compressor; a second temperature sensor 14 senses a temperature of the cooling medium within an intake tubing, through which the cooling medium is taken into the inlet of the compressor; and a microcomputer 12 calculates a super-heat quantity of the cooling medium taken into the compressor on the basis of a difference between the outputs of the first and second temperature sensors, and controls a degree of opening of the electrically operated expansion valve, thereby enabling the refrigeration cycle to be operated at high efficiency and in an energy- saving mode. The speed of the compressor is controlled in dependence upon the difference between actual and desired temperature of a space whose temperature is being controlled.
