Self-adjustable dehumidification drying heat pump control system and method

Abstract

The invention discloses a self-adjustable dehumidification drying heat pump control system and method. Through cooperation of a temperature detection unit and an action execution unit which are arranged, temperature and humidity adjustable adaptive response is formed. The action execution unit is provided with a closed refrigerant circulation unit and a closed air circulation unit. A temperature adjusting unit is arranged in the closed refrigerant circulation unit. A humidity adjusting unit is arranged in the closed air circulation unit. The temperature adjusting unit has the functions of adjusting based on the condensing area of the condensing end inside the closed refrigerant circulation unit and adjusting based on the evaporation area of the evaporation end inside the closed refrigerantcirculation unit. The functions of adjusting based on the heat exchange air volume of the condensing end inside the closed refrigerant circulation unit and adjusting based on the heat exchange air volume of the evaporation end inside the closed refrigerant circulation unit are formed in the humidity adjusting unit. By forming the four appropriate adjusting functions, self-adjustable dehumidification drying well matched with a low-temperature humidification mode, a low-temperature dehumidification mode, a medium-temperature drying mode, a high-temperature drying mode and a ventilation mode isformed.

Description

technical field [0001] The invention belongs to the field of drying, and in particular relates to a control system and method of a self-adjusting dehumidification and drying heat pump. Background technique [0002] At present, there are more and more places that need hot air drying in the market, such as tobacco drying, grain drying, medicinal materials drying, fruit and vegetable drying and other drying places. Coal furnaces, gas furnaces and electric furnaces are mainly used for drying. Coal and gas are non-renewable strategic energy sources, which are not the direction of national promotion. Electric furnaces are not suitable for mass promotion because of their high energy consumption and high operating costs. For the many reasons mentioned above, heat pumps are gradually being accepted by the market because of their many advantages such as energy saving, environmental protection, and high drying quality. There are two main types of drying heat pumps on the market, one i...

AI Technical Summary

Problems solved by technology

There are mainly two types of drying heat pumps on the market, one is hot air dehumidification drying, this drying method is suitable for places that require fast water discharge and high drying temperature; the other is dehumidification drying, Suitable for places with low drying water rate and low drying temperature
