Abstract
(EN)
There is a growing need for dehumidification control in refrigerated transport containers with an intermittently operated compressor. The disclosed system and method of dehumidification control, controlling the speed of one or more evaporator fans and a heating unit, meets that need using one or more dehumidification need indicators and one or more condensation indicators. More specifically a system for and method is disclosed, comprising: controlling the operation of the one or more evaporator fans (10) for dehumidification purposes according to: if a need for dehumidification is determined using at least one dehumidification need indicator and if at least one condensation indicator indicates that the evaporator (16) is sufficiently cold respectively too warm for condensation or deposition of water vapour on its external surface, then setting or maintaining the speed of the one or more evaporator fans (10) to a reduced speed (LOW) in order to increase a condensation or deposition rate respectively to an increased speed (HIGH) in order to increase heat load to the evaporator (16), respectively. In other embodiments the system and method controls the heating unit as well.

L'invention concerne le besoin croissant en commande de déshumidification dans des conteneurs de transport réfrigérés comprenant un compresseur actionné par intermittence. Le système et le procédé de commande de déshumidification selon l'invention, par commande de la vitesse d'un ou de plusieurs ventilateurs d'évaporateur et d'une unité de chauffage, permet de palier ce besoin au moyen d'un ou de plusieurs indicateurs de besoin de déshumidification et d'un ou de plusieurs indicateurs de condensation. L'invention concerne un particulier un système et un procédé comprenant : la commande de fonctionnement d'un ou de plusieurs ventilateurs d'évaporateur (10) à des fins de déshumidification dans les conditions suivantes : si un besoin de déshumidification est déterminé au moyen du ou des indicateurs de besoin de déshumidification et si le ou les indicateurs de condensation indiquent que l'évaporateur (16) est suffisamment froid, respectivement trop chaud, pour la condensation ou le dépôt de vapeur d'eau sur sa surface externe, puis la détermination ou le maintien de la vitesse du ou des ventilateurs d'évaporateur (10) à une vitesse réduite (BASSE) afin d'augmenter un taux de condensation ou de dépôt, respectivement, à une vitesse augmentée (HAUTE) afin d'augmenter la charge thermique de l'évaporateur (16), respectivement. Dans d'autres modes de réalisation, le système et le procédé commandent également l'unité de chauffage.
