AIR-CONDITIONING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18277583 titled 'AIR-CONDITIONING APPARATUS
The abstract of the patent application describes an air-conditioning apparatus that selects a dehumidifying operation mode based on a sensible heat ratio difference when transitioning from a cooling operation mode to a dehumidifying operation mode.
- The apparatus determines the sensible heat ratio difference (ÎSHF) by comparing the target sensible heat ratio with the theoretical minimum possible sensible heat ratio.
- It acquires the target sensible heat ratio from indoor temperature, target indoor temperature, and target indoor humidity.
- The theoretical minimum possible sensible heat ratio is obtained from the enthalpy of indoor air, blown air from the indoor unit at 100% relative humidity, and sensible heat enthalpy.
Potential Applications: - This technology can be used in residential and commercial air-conditioning systems to improve energy efficiency and comfort. - It can also be applied in industrial settings where precise control of indoor climate conditions is required.
Problems Solved: - Addresses the challenge of efficiently transitioning between cooling and dehumidifying modes in air-conditioning systems. - Helps optimize energy consumption by selecting the most appropriate dehumidifying operation mode based on sensible heat ratio.
Benefits: - Improved energy efficiency and cost savings in air-conditioning operations. - Enhanced comfort and indoor air quality for occupants. - Reduced wear and tear on the air-conditioning system components.
Commercial Applications: - HVAC companies can integrate this technology into their air-conditioning units to offer more advanced and energy-efficient solutions to customers. - Property developers can incorporate this innovation in their buildings to provide a superior indoor climate control experience.
Questions about the technology: 1. How does the apparatus determine the target sensible heat ratio? 2. What are the key factors influencing the selection of the dehumidifying operation mode based on the sensible heat ratio difference?
Original Abstract Submitted
An air-conditioning apparatus includes configured to, when a cooling operation mode is changed into one of multiple dehumidifying operation modes, select the one of the multiple dehumidifying operation modes on the basis of a value of a sensible heat ratio difference ÎSHF that is a difference between a target sensible heat ratio acquired from an indoor temperature detected by an indoor temperature sensor, a target indoor temperature, and target indoor humidity and a theoretical minimum possible sensible heat ratio acquired from enthalpy of an indoor air, enthalpy of blown air from the indoor unit when relative humidity is 100%, and enthalpy of sensible heat.
