AIR-CONDITIONING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18549006 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. - It can also be applied in heat pump systems for heating purposes.
Problems Solved: - Provides a more efficient and optimized air-conditioning system. - Ensures proper sizing of heat-medium conveying pipes for effective heat transfer.
Benefits: - Improved energy efficiency in air-conditioning and heat pump systems. - Enhanced performance and reliability of the cooling and heating processes.
Commercial Applications: Commercial HVAC systems, residential air-conditioning units, heat pump systems for buildings and industrial facilities.
Questions about the technology: 1. How does the sizing of heat-medium conveying pipes impact the overall efficiency of the air-conditioning system? 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):
