Climate control system for a mushroom growing appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mushroom growing appliances face issues with mushroom spore build-up, which affects the operation of recirculation fans and fail to maintain optimal humidity and gas concentrations, leading to suboptimal growing conditions.
Innovation Solution
A mushroom growing appliance with a climate control system that includes a water reservoir, wicking filter, and dual fans - a recirculation fan and a fresh air fan - to manage air flow and humidity, using a wicking filter to both filter out spores and humidify the environment, while maintaining desired gas concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a recirculation fan is used to circulate air in the grow chamber, then air circulation is improved, but the fan becomes clogged with mushroom spores reducing its operational reliability
Solution Approach 1:
A recirculation filter is introduced as an intermediary component between the recirculation fan and the grow chamber air. The filter captures mushroom spores before they can reach and clog the fan, allowing the fan to continue circulating air reliably while the filter is easily removed and cleaned or replaced
2Quantity of substance
If a fresh air fan is used to add oxygen and remove carbon dioxide, then gas concentration control is improved, but the incoming air dries out the mushrooms if not properly humidified
Solution Approach 1:
The fresh air fan and humidification filter functions are merged into a single integrated component. The filter is positioned to receive incoming fresh air, capture spores, and simultaneously provide humidification to the air stream before it enters the grow chamber, ensuring both gas exchange and moisture maintenance occur together
Solution Approach 2:
A humidification filter serves as an intermediary between the fresh air fan and the grow chamber environment. This filter pre-humidifies the incoming air, preventing direct contact between dry fresh air and mushrooms, thereby maintaining mushroom moisture while still achieving oxygen addition and carbon dioxide removal
3Object-affected harmful factors
If conventional filtering methods are used, then spore removal is achieved, but the filter does not provide humidification functionality
Solution Approach 1:
The filter is designed to perform multiple functions simultaneously: it filters out mushroom spores from the air, provides humidification to the air stream, and serves as a water reservoir for the humidification process. This multi-functionality eliminates the need for separate humidification equipment, reducing overall system complexity while achieving both spore removal and humidification
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces spore build-up, maintains optimal humidity levels, and regulates carbon dioxide concentrations, creating a better growing environment for mushrooms by utilizing the wicking filter to humidify and filter the air.
Implementation Method 1
a wicking filter positioned at least partially within the water reservoir for wicking the water into the wicking filter
Implementation Method 2
a recirculation fan positioned adjacent the wicking filter for selectively urging a flow of recirculation air through the wicking filter and back into the grow chamber
Implementation Method 3
a fresh air fan positioned adjacent the wicking filter for urging a flow of fresh air through the wicking filter and into the grow chamber
Implementation Method 4
using a wicking filter to both filter out spores and humidify the environment
