| The Scientific and Technological Appraisal of Longertek’s Inverter Multi-Air Conditioning System |
On the 28th of May 2006, the Science and Technology Bureau of Qingdao chaired a meeting to appraise the scientific and technological results of the multi air conditioning system of Longertek’ internet
intelligent inverter central air conditioning. The attending exports listened to the technology work report,
technology research report and the novelty search report, and examined the related materials. After a
series of enquiries, arguments and serious discussion, the exports reached the following conclusion:
First, the technological materials offered are complete and real, the tested data is reliable.
Second, the series of products suit the development direction of energy saving air conditioning and have the following originalities:
- Achieved PPD (Power Proportional Distribution) in multi air conditioning and
achieved independent billing of the central air conditioning users;
- Applied innovatively the optimised thermodynamics technology and the refrigerant flow
control technology; achieved independent temperature control of different rooms;
- Adopted group control technology, which can be used for indoor units’ group control
and is convenient for the administrator’s centralised management;
- Implemented remote control technology; the equipments can be controlled through the
Internet, telephone and mobile, which meets people’s requirement towards a
modern life and towards office building’s automatic control.
All the appraisal exports agreed that this technology is the leading one in China. They also
suggested that in order to meet the market needs, the industrial arts should be optimised and the
production scale should be expanded.
