Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If electric auxiliary heating is used to improve heating capacity, then heating capacity is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the compressor capacity adjustable through a switching mechanism that can load or unload cylinders based on operating conditions. This dynamic adjustment allows the compressor to adapt its displacement to match heating demands, replacing the need for electric auxiliary heating and thereby improving energy efficiency while maintaining heating capacity.
Solution Approach 2:
The patent changes the parameter of compressor displacement by implementing a capacity variation switching mechanism. This mechanism allows the compressor to vary its operating capacity by switching between different cylinder configurations (loaded/unloaded states), enabling optimal matching of heating output to demand without energy-wasting auxiliary heating.
2Temperature
If a compressor with two-stage enthalpy-increasing function is used to improve low-temperature heating capacity, then low-temperature heating capacity is improved, but energy efficiency under common working conditions deteriorates due to fixed displacement
Solution Approach 1:
The patent introduces dynamics by implementing a capacity variation switching mechanism that can dynamically adjust the number of loaded cylinders based on operating conditions. This allows the compressor to operate with optimal displacement for both low-temperature heating and common working conditions, resolving the contradiction between fixed displacement and variable energy efficiency requirements.
Solution Approach 2:
The patent applies universality by designing a compressor system that can perform multiple functions through the capacity variation switching mechanism. The same compressor can adapt to different operating modes (low-temperature heating, common working conditions, partial loading) by switching cylinder loading states, making it universally efficient across diverse operating scenarios.
3Temperature
If displacement cannot be adjusted to ensure heating capacity and energy efficiency under low-temperature conditions, then heating capacity is maintained, but adaptability to operating conditions deteriorates
Solution Approach 1:
The patent implements dynamics through the capacity variation switching mechanism that can dynamically adjust displacement by loading or unloading cylinders. This dynamic capability allows the compressor to maintain heating capacity under low-temperature conditions while simultaneously adapting to different operating conditions, thereby improving overall versatility.

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 compressor achieves high adaptability and energy efficiency by varying capacity and volume ratios, enhancing heating performance and overall energy efficiency across different operating conditions.
Implementation Method 1
when the pressure control portion is communicated with the air inlet of the compressor, the locking member is locked to the sliding sheet of the third cylinder to make the third cylinder unloaded, and when the pressure control portion is communicated with the air outlet of the compressor, the locking member is unlocked with the sliding sheet of the third cylinder to make the third cylinder loaded

AI summary
Disclosed is a compressor, including a crankshaft (10), and a first cylinder (20), a second cylinder (30) and a third cylinder (40) arranged sequentially in an axial direction of the crankshaft (10). The first cylinder (20) is a high-pressure cylinder, and the second cylinder (30) and the third cylinder (40) are low-pressure cylinders. The compressor also includes a capacity variation switching mechanism (50) for controlling unloading or loading of the third cylinder (40). The compressor has a full operation mode and a partial operation mode. When the compressor is in the full operation mode, the capacity variation switching mechanism (50) loads the third cylinder (40) under the action of the discharge pressure of the compressor, and when the compressor is in the partial operation mode, the capacity variation switching mechanism (50) unloads the third cylinder (40) under the action of the inlet pressure of the compressor. Also disclosed is a heat exchange system including the compressor. By means of the capacity variation switching mechanism (50) provided in the compressor, at least one cylinder is allowed to be put into use or unloaded under the action of the capacity variation switching mechanism (50), thus enabling a capacity variation switching function of the compressor to meet operational requirements of different operating conditions and to improve the heating capacity of the compressor under different working conditions.
