Framtagning av nytt mätsystem för mätning av energiförbrukning i mikrovågsugnar
The report describes a measuring method for analysis of energy consumption measurement in microwave ovens. Concurrently that the awareness of the environment evolves the demands are growing for more power saving products. This is also counting within the Home Appliance business, which is Whirlpools business area. Whirlpool is therefore interested of launching microwave ovens with documented low power consumption. To be able to implement this, both asserted measuring equipment, that fulfils all demands, and a standard procedure is required. Asthis is a comparatively new business area within microwave oven production, there is no definite standard to follow. There is however a proposal developed by CENELEC. The report describes the suggested measuring method and analyses and evaluates it. Proposal is also given on how to refine the measuring method and evolve it further. The developed measuring equipment is carefully described in the report. The software to the measuring equipment has been developed using National Instrument?s LabVIEW®. LabVIEW® is a powerful and comparatively easy-to-use tool often used when developing measuring systems. The developed hardware?s main task is to detect which heating element (grill, forced air, microwaves) that is active in the microwave oven. This is very useful when verifying programs for cooking in the oven. Eventually it is the authors hope that the system will be used within Whirlpool, and also be developed further.
