Air conditioning controller special for curing tobacco and control method thereof

Abstract

The invention relates to an air conditioning controller special for curing tobacco and a control method thereof. The special air conditioning controller for curing tobacco comprises a wire controller; the wire controller comprises an input unit and an MCU of the wire controller, which are connected; the MCU of the wire controller is respectively connected with a first display unit, a cured tobacco curve, a tobacco-curing recording memory unit, a spare power supply unit, a dry-bulb temperature and wet-bulb temperature detection unit, a load control interface unit, a heat pump system protective unit and a three-phase power fault tolerant unit; and the MCU of the wire controller receives a control instruction from the input unit so as to control the working states of a heat pump and an electric heating and dehumidifying device. The air conditioning controller utilizes the heat pump heating technology and a heat recovery device in the process of curing tobacco, can reduce the air pollution and save energy, can also improve the curing quality of the tobacco and reduce the working intensity of curing tobacco, control the dry-bulb temperature and the wet-bulb temperature in a curing room precisely and greatly improve the automation degree and the control precision.

Description

technical field [0001] The invention relates to an air conditioner controller, in particular to an air conditioner controller dedicated to flue-cured tobacco and a control method thereof. Background technique [0002] Common tobacco leaf baking and heating equipment basically adopts a coal furnace, the hot gas in the coal furnace is directly discharged into the air after passing through the tortuous hot gas channel, and the dry bulb temperature in the baking room is controlled by controlling the flame size of the coal furnace. For example, Chinese Patent Document No. CN2812598Y discloses a hot air circulation machine baking room, which includes a smoke chamber, a moisture exhaust skylight, a heating device and a hot air circulation device. It is characterized in that: the four walls of the smoke chamber are perpendicular to each other, and the walls There are 4 to 6 cold air tunnels with movable doors at the base, and four layers of smoke hanging beams are set on the wall to...

AI Technical Summary

Problems solved by technology

[0003] 1. Usually, the hot air still has a high temperature after leaving the pipeline, and the energy utilization rate is low;

[0004] 2. The gas after coal combustion is directly discharged into the air without any treatment, causing serious pollution;

[0005] 3. Due to the lack of convection in the air inside the baking room, the dry bulb temperature and wet bulb temperature in different positions inside the baking room are also inconsistent;

[0006] 4. Due to the inability to accurately control the flame size of the coal furnace, the dry bulb temperature control of the baking room is also inaccurate;

[0007] 5. Through indoor and outdoor ventilation and dehumidification, the heat loss is serious;

[0008] 6. The baking room uses an open flame as a heat source, which may cause huge losses due to fire leakage and combustion, with low safety and high energy consumption

This kind of temperature and humidity monitoring system in the tobacco leaf warehouse can only give an alarm based on the detection results, but cannot handle it in a timely manner, and its degree of automation is relatively low
