Title (EN) DEHUMIDIFIER
(FR) DÉSHUMIDIFICATEUR
Abstract:
(EN) A dehumidifier (100) and a method of dehumidification(100) are provided. The dehumidifier (100) comprises: a housing (110) provided with at least one air inlet(111) and at least one air outlet (112), wherein an air channel (113) connecting the air inlet (111) to the air outlet (112) is formed inside the housing (110); a condensing (120) assembly disposed in the housing (110); a throttle valve (130) connected to an outlet of the condensing (120) assembly; an evaporator (140) provided between the condensing (120) assembly and the air inlet (111); and a compressor (150), an outlet of the compressor (150) is communicated with an inlet of the condensing (120) assembly, wherein an inlet of the compressor (150) is communicated with an outlet of the evaporator (140), and the compressor (150), the condensing (120) assembly, the throttle valve (130) and the evaporator (140) are sequentially connected in series to form a refrigerant circuit. As a result, the temperature difference of the air between the evaporator and the condenser is reduced, so that the difference of the amount of air heat exchange between the evaporator and the condenser is decreased. Therefore, the temperature of the condenser and the evaporator can be in a relative stable state regardless of magnitude of air flow, which improves the dehumidification energy efficiency of the dehumidifier.
(FR) L'invention concerne un déshumidificateur (100) et un procédé de déshumidification (100). Le déshumidificateur (100) comprend : une enveloppe (110) munie d'au moins une entrée d'air (111) et d'au moins une sortie d'air (112), un canal d'air (113), reliant l'entrée d'air (111) à la sortie d'air (112), étant formé à l'intérieur de l'enveloppe (110) ; un ensemble de condensation (120) disposé dans l'enveloppe (110) ; une vanne d'étranglement (130) reliée à une sortie de l'ensemble de condensation (120) ; un évaporateur (140) agencé entre l'ensemble de condensation (120) et l'entrée d'air (111) ; et un compresseur (150), une sortie du compresseur (150) étant en communication avec une entrée de l'ensemble de condensation (120), une entrée du compresseur (150) étant en communication avec une sortie de l'évaporateur (140), et le compresseur (150), l'ensemble de condensation (120), la vanne d'étranglement (130) et l'évaporateur (140) étant reliés successivement en série afin de former un circuit de fluide frigorigène. Par conséquent, la différence de température de l'air entre l'évaporateur et le condenseur est réduite, ce qui permet de diminuer la différence de quantité d'échange de chaleur d'air entre l'évaporateur et le condenseur. De ce fait, la température du condenseur et de l'évaporateur peut être en état relativement stable indépendamment de la grandeur de l'écoulement d'air, améliorant ainsi l'efficacité énergétique de déshumidification du déshumidificateur.
