Air energy grain drying and refrigeration energy-saving integrated device and intelligent controlling method thereof

Abstract

The invention discloses an air energy grain drying and refrigeration energy-saving integrated device. The air energy grain drying and refrigeration energy-saving integrated device comprises a remote monitoring center, a heat pump system, drying equipment, a cold storage and cold air recycling equipment, wherein the cold air recycling equipment comprises a first air door, a second air door, a coldair output pipe, a cold storage air feeding pipe, a cold storage air returning pipe and an air input pipe; a cold air output hole of the heat pump system is separately connected with the cold storageair feeding pipe and cold air output pipe through the first air door; the cold storage air feeding pipe is connected between the first air door and a cold storage air inlet; the first air door has a first communication state and a second communication state; an air inlet of the heat pump system is separately connected with the air input pipe and the cold storage air returning pipe through the second air door; the cold storage air returning pipe is connected between the second air door and the cold storage air returning hole; and the second air door has a third communication state and a fourthcommunication state. The air energy grain drying and refrigeration energy-saving integrated device disclosed by the invention has the advantages that through additional arrangement of the cold air recycling equipment, recycling of cold air can be realized, design of the grain drying and refrigeration integrated device is realized, so that the effect of one machine with multiple purposes can be achieved.

Description

technical field [0001] The invention relates to the technical field of low-carbon environmental protection of grain drying and storage, in particular to an air energy grain drying and refrigeration energy-saving integrated device and an intelligent control method thereof. Background technique [0002] According to the development goals of agriculture and rural economy, grain drying is an important part of grain production, such as plowing, sowing, harvesting, drying, etc. of work. However, on the one hand, many of the existing grain drying equipment still use coal-fired (fuel oil) hot air stoves with high energy consumption, high pollution, and low degree of automation as the main heat source, which has high energy consumption and emissions of pollutants such as smoke, carbon dioxide, and sulfur dioxide. Advanced issues; on the other hand, some grain dryers that use clean energy will cause energy waste during the drying process. [0003] Authorized patent ZL201210568843.2 ...

AI Technical Summary

Problems solved by technology

However, this patent only recovers the waste heat baked in the drying room, and does not consider the characteristics of the air source heat pump.

According to the inverse Carnot principle, the heat pump system absorbs the heat in the air and turns it into heat and transfers it to the grain dryer. The large air volume will cause waste of electric energy, generate vibration and noise, and affect the environment
