Problems solved by technology
But what needs to be considered is that when the multi-connected heat pump drying unit is applied to the drying room group, it is difficult for the user to observe the status of each drying room at the same time, and the user needs to adjust the drying end of a certain drying room. Finally, it may lead to a situation that affects the whole body, which will affect other drying rooms, but the user cannot know in time

The application relates to a multi-connection heat pump drying control method and device and a multi-connection heat pump drying unit, belonging to the technical field of heat pump drying control. This application includes: obtaining the proportion of the number of starting up of the drying end, obtaining the temperature of the drying space corresponding to each drying end in operation, and obtaining the time-temperature control parameters corresponding to the objects to be dried; according to the proportion of the number of starting up, Each drying end in operation corresponds to the temperature of the drying space and time-temperature control parameters to obtain the output frequency of the heat pump compressor; control the heat pump compressor to operate at the output frequency. Through this application, it is helpful to realize the dynamic balance between the output of the heat pump compressor and the demand of multiple drying rooms, and help to make each drying room meet the requirements of the drying process, thereby helping to ensure the drying of each drying room quality.
Description
technical field [0001] The application belongs to the technical field of heat pump drying control, and in particular relates to a multi-connection heat pump drying control method, a device and a multi-connection heat pump drying unit. Background technique [0002] The heat pump drying unit can be applied to the drying and dehydration of food, medicinal materials, wood, agricultural and sideline products, industrial products, etc. Specifically, the items to be dried are placed in the drying room, and heat is delivered to the drying room through the heat pump drying unit. The air takes away the moisture in the to-be-dried object to achieve the purpose of drying. [0003] In specific applications, ordinary heat pump drying units are common, and its configuration is that one outdoor unit is equipped with one indoor unit, and a set of ordinary heat pump drying units can only be used for drying in one drying room. For a group of contiguous drying rooms, if ordinary heat pump dryi...
