Multifunctional heat pump drying and humidifying system for building and operation method of multifunctional heat pump drying and humidifying system

Abstract

The invention provides a building multifunctional heat pump drying and humidifying system and an operation method thereof. The building multifunctional heat pump drying and humidifying system comprises a drying room adjusting system, a fresh-keeping room adjusting system and a cooling liquid circulating system, and cooling liquid of the drying room adjusting system and cooling liquid of the fresh-keeping room adjusting system are recycled through the cooling liquid circulating system. The design is reasonable, the humidity sensor is used for detecting the return air humidity, the return air processing mode is judged, when the return air humidity is too high, heat is exhausted and recovered through the heat recoverer, when the return air humidity is within the available range, whether dehumidification is needed or not is further judged, the drying efficiency can be effectively improved, the drying time is saved, the drying cost is saved, and the drying efficiency is improved. Meanwhile, by means of the multifunctional heat pump drying and humidifying system for the building, the optimal operation mode can be selected according to return air humidity changes and different drying requirements, and the integration of drying and fresh keeping is achieved through the cooling capacity of the heat exchanger end.

Description

technical field [0001] The invention relates to a multifunctional heat pump drying and humidity regulating system for buildings and an operation method thereof. Background technique [0002] Heat pump drying is an energy-saving technology for clean, safe, efficient and intelligent drying process. The research on heat pump drying system and heat pump drying process has been supported by the state. Heat pump drying has always been a shortcoming in my country's drying market. The average drying rate of food, tea, medicinal materials and sludge is relatively low, but because of this, the current market share of dryers is low, while air source heat pump drying As a new type of energy-saving and environmental protection equipment rapidly developed by air source heat pump instead of traditional coal-fired gas drying furnace, dry room has a large market demand and great potential for future development. The heat pump drying technology has the advantages of less energy consumption, l...

AI Technical Summary

Problems solved by technology

Heat pump drying has always been a shortcoming in my country's drying market. The average drying rate of food, tea, medicinal materials, and sludge is relatively low. As a new type of energy-saving and environmental protection equipment developed rapidly by replacing traditional coal-fired gas-fired drying furnaces with air-source heat pumps, dry rooms have a large market demand and great potential for future development

The heat pump drying technology has the advantages of less energy consumption, less environmental pollution, and a wide range of applications. However, in the actual operation process, there is still no effective heat treatment plan for the large amount of heat generated by material drying. It is a huge waste. At the same time, drying has precise humidity requirements, and the problem of high humidity in the drying room after drying has yet to be solved.
