Solution Overview
Problem
Conventional anti-start air conditioning systems for vehicles are complex, bulky, and difficult to make portable due to their structure, which complicates the addition of heating functions and requires a heater core or PTC heater, limiting their functionality and portability.
Innovation Solution
An air conditioning system with a single air-conditioning case that includes a cold air passageway for the evaporator, a warm air passageway for the condenser, and a mounting space for the compressor, allowing for both cooling and heating functions without a heater core or PTC heater, and is designed to be detachable and compact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a heater core or PTC heater is added to provide heating function, then heating capability is improved, but device complexity and system bulk increase
Solution Approach 1:
The condenser is designed to serve dual purposes: acting as a heat dissipation device during cooling mode and as a heat exchange device for heating mode. By reversing the refrigerant flow direction and utilizing the condenser's heat exchange capability in both heating and cooling cycles, the system achieves heating function without requiring separate heater components, thereby reducing device complexity while maintaining versatility
Solution Approach 2:
The patent merges the heating and cooling functions into a single integrated system by combining the condenser's dual-mode operation with a unified control mechanism. The single door structure integrates both heating and cooling mode controls, and the refrigerant circulation system is designed to switch between heating and cooling cycles through flow direction reversal, consolidating multiple functions into one compact system
2Adaptability or versatility
If conventional anti-start air conditioning system structure is used, then cooling function is provided, but portability and compactness are reduced
Solution Approach 1:
The patent combines all air conditioning components (compressor, condenser, evaporator, expansion valve) and control mechanisms into a single integrated air-conditioning case. The single door structure unifies access to both heating and cooling components, and the refrigerant circulation system is consolidated into one compact loop, significantly reducing the overall system volume and improving portability while maintaining full functionality
Solution Approach 2:
The system is designed as a universal air conditioning unit that can operate in both heating and cooling modes within a single compact structure. By making the entire system portable and detachable while maintaining dual-mode operation capability, the invention achieves adaptability across different usage scenarios without requiring separate fixed installations
3Volume of moving object
If single air-conditioning case with integrated components is used, then compactness and simplicity are improved, but heat exchange efficiency may be reduced
Solution Approach 1:
The air-conditioning case is divided into distinct functional compartments: a mounting space for the compressor, a cold air passageway for the evaporator, and a warm air passageway for the condenser. These segmented spaces are arranged in specific spatial relationships to optimize heat exchange efficiency while maintaining a compact overall structure, ensuring that each component operates in its optimal thermal environment
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement within the single air-conditioning case to position components optimally. The compressor, condenser, and evaporator are arranged in different spatial zones with dedicated air passageways, allowing efficient heat exchange in multiple directions and planes while maintaining a compact footprint, thus preserving heat exchange efficiency despite the reduced overall volume
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 provides both cooling and heating functions in a simple, compact design, enabling portability and easy operation with a single door for mode control, reducing noise with sound-absorbing materials, and efficiently transferring air volume in both modes.
Implementation Method 1
the evaporator 4 exchanges heat between the refrigerant and air blown to the interior of the vehicle by a blower (not shown). Then, the refrigerant is evaporated in the evaporator 4 and discharged in a gaseous phase of low-temperature and low-pressure.
Implementation Method 2
the condenser 2 condenses the gas-phase refrigerant into liquid-phase refrigerant of high-temperature and high-pressure by exchanging heat with outdoor air.
Implementation Method 3
the compressor 1 inhales and compresses gas-phase refrigerant of low-temperature and low-pressure while driving by driving power of an engine or a motor, and then sends the refrigerant in the gaseous phase of high-temperature and high-pressure to the condenser 2.
Implementation Method 4
the liquid-phase refrigerant of high-temperature and high-pressure sent from the condenser 2 rapidly expands by a throttling action of the expansion valve 3 and is sent to the evaporator 4 in a wet-saturated state of low-temperature and low-pressure.

AI summary
The present invention relates to an air conditioning system and, more particularly, to an air conditioning system comprising, within a single air conditioning case: a cool air passage in which an evaporator is installed; a warm air passage in which a condenser is installed; an installation space portion in which air conditioner parts such as a compressor are installed; and an air discharge passage for discharging, to the outside, air unnecessary for cooling and heating, thereby enabling attachment and detachment inside a vehicle, and enabling use as a portable air conditioner as well as a vehicle air conditioner. In addition, as the system is capable of cooling and heating, a separate heater core or PTC heater for heating is not required, thereby the structure is simple, and the system is capable of controlling cooling and heating modes through a single operation door, thereby allowing the system to be miniaturized.
