AIR-CONDITIONING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240302085 titled 'AIR-CONDITIONING APPARATUS
The air-conditioning apparatus described in this patent application consists of a refrigerant cycle circuit and a heat-medium cycle circuit.
- The refrigerant cycle circuit includes a compressor, a heat-source-side heat exchanger, an expansion device, and a refrigerant-side flow passage of an inter-heat-medium heat exchanger connected by refrigerant pipes for circulating refrigerant.
- The heat-medium cycle circuit includes a pump, a use-side heat exchanger, and a heat-medium-side flow passage of the inter-heat-medium heat exchanger connected by heat-medium conveying pipes for circulating the heat medium.
- The inside diameter of the heat-medium conveying pipes is determined based on the capacity of the use-side heat exchanger and the length of the pipes, satisfying a specific formula.
Potential Applications: - This technology can be used in various air-conditioning systems for efficient cooling and heating. - It can also be applied in industrial settings where precise temperature control is required.
Problems Solved: - Provides a more efficient and reliable air-conditioning system. - Ensures optimal heat transfer between the refrigerant and heat medium.
Benefits: - Improved energy efficiency. - Enhanced performance and durability of the air-conditioning apparatus.
Commercial Applications: Commercial HVAC systems, refrigeration units, and industrial cooling systems can benefit from this innovative technology.
Questions about the technology: 1. How does the sizing of the heat-medium conveying pipes impact the overall efficiency of the air-conditioning apparatus? 2. What are the key differences between traditional air-conditioning systems and the one described in this patent application?
Original Abstract Submitted
an air-conditioning apparatus according to the present disclosure includes: a refrigerant cycle circuit in which a compressor, a heat-source-side heat exchanger, an expansion device, and a refrigerant-side flow passage of an inter-heat-medium heat exchanger are connected by refrigerant pipes, and refrigerant is circulated; and a heat-medium cycle circuit in which a pump, a use-side heat exchanger, and a heat-medium-side flow passage of the inter-heat-medium heat exchanger are connected by heat-medium conveying pipes, and the heat medium is circulated. an inside diameter d of each of the heat-medium conveying pipes is determined based on a capacity q of the use-side heat exchanger connected to the heat-medium conveying pipes and a length l of at least part of each of the heat-medium conveying pipes included in the heat-medium cycle circuit, and is set to satisfy the following formula (1):
