Previous Career

I belonged to Intellectual Property Department and Design/Development Department in a leading gas appliance manufacturer. In the Intellectual Property Department, I was involved in preparation of a number of patent applications relating to overall gas appliances such as gas cooking stoves, gas water heaters, gas rice cookers, gas air conditioners, gas fryers, etc. In the Design/Development Department, I developed/designed absorption refrigerators (gas air conditioners) and gas cooking stoves and gained a practical experience as an inventor of patent applications. My time at this manufacturer has given me more in-depth knowledge and understanding of gas appliances and the related techniques (heat exchangers (fin tube type, etc.), burner combustion systems (all primary combustion burners, etc.), frame traps, combustion control, water temperature control, concentration control of lithium bromide-water solution and others).
