Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners waste water resources by not recycling condensed water and consume excessive power due to large temperature differences between outside and indoor environments.
Innovation Solution
An air conditioner ventilation and pre-cooling device that recycles condensed water by using it for heat exchange with a cooling unit to pre-cool outside air, reducing the temperature difference and thus lowering power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If outside fresh air is guided into the indoor environment, then ventilation function is improved, but power consumption increases due to temperature difference
Solution Approach 1:
The patent applies preliminary action by pre-cooling the outside air using condensed water before it enters the indoor environment. The cooling unit utilizes the low-temperature condensed water to cool the incoming air in advance, reducing the temperature difference that the indoor air conditioner must handle, thereby lowering power consumption while maintaining ventilation function
Solution Approach 2:
The patent implements self-service by using the condensed water produced by the air conditioner's own evaporator to pre-cool the ventilation air. The system recycles its own waste resource (condensed water) to serve the ventilation function, creating a self-sufficient loop that reduces external energy requirements
2Temperature
If evaporator produces condensed water by heat exchange, then cooling function is improved, but water resources are wasted due to lack of recycling
Solution Approach 1:
The patent applies discarding and recovering by capturing the condensed water that would otherwise be discarded from the evaporator and recovering its cooling potential. The condensed water is directed to the cooling unit where it continues to provide cooling effect before being discharged, thereby recovering the water's thermal energy and preventing resource waste
Solution Approach 2:
The system makes the condensed water serve a secondary function by using it to pre-cool ventilation air through the cooling unit. This self-service approach allows the condensed water to continue providing cooling benefits after its primary condensation function is complete, maximizing resource utilization

Function Achieved in This Case
This solution achieves environmental protection and power saving effects while improving cooling efficiency by reducing the temperature difference between outside and indoor environments, and ensures water resource conservation through recycling.
Implementation Method 1
a cooling unit which is thermal connected to the condensed water and exchanges heat with the condensed water
Implementation Method 2
heat of the air conditioner is absorbed and conducted to the condensed water
Implementation Method 3
heat exchanged between the outside air flowing through the cooling unit and the cooling unit
Implementation Method 4
the outside air passing through the cooling unit will carry away the heat of the cooling unit

AI summary
An air conditioner ventilation and pre-cooling device includes a carrying container, a cooling unit and an intake fan. The carrying container is provided for containing condensed water of the evaporator, the cooling unit is connected to the condensed water, and the intake fan guides outside air to pass through the cooling unit. The heat of the condensed unit is conducted to the cooling unit, and the outside air passes through the cooling unit and exchanges heat with the cooling unit to form a pre-cooled air. The outside air is pre-cooled before it enters into an indoor environment, so as to achieve the environmental protection and power saving effects and improve the cooling efficiency.
