Application overview Today environmental air conditioning has become a mass commodity: the presence of an air conditioner in a home or car, something that was rather rare up until a few decades ago, has now become commonplace. The current situation, especially during the summer, determines consumption levels that account for a significant percentage of the national electricity requirements. What is more, it must not be forgotten that the use of domestic air conditioners is mainly concentrated during the daytime hours, when the demand for electricity reaches the highest levels, exacerbating the...

Since the performance of an air conditioner is highly dependent on the temperature and humidity values of both the conditioned and the external environments, the climatic chamber is an irreplaceable simulation instrument. However it is not exhaustive, because it is necessary to measure the thermal power the conditioner is able to exchange with the outside. For this reason the calorimeter, used both for domestic and car air conditioners, is the most important instrument in both the development phase and, when necessary, the certification phase.

Standard calorimeters for domestic air conditioners Automobile air conditioners are highly customized on the basis of the vehicle in which they will be installed. This is true for both the geometries used and the cooling capacities delivered. On the other hand, domestic air conditioners, even though there are numerous manufacturers on the market share many of the same elements in their construction solutions and performances. For domestic air conditioners, specific standards of reference are in use in all industrialized countries, establishing how they are to be tested and permitting a clear-cut...

The basic configuration includes: * no. 4 portholes for cables entry * no. 2 windows (mm 450x450) * no. 2 inside power plugs * PC and WinKratos control S/W * Code tester sensors * Thermal efficiency calculus

Control system overview WinKratos is the software developed byAngelantoni Test Technologies for the monitoring and supervision of climatic chambers and environmental testing systems. The extremely flexible and powerful structure of this package has been further perfected to afford complete integration and effectiveness of use with the calorimeter. The machine and its functions are managed and monitored by means of a Siemens S7 controller. This controller is responsible for acquiring the chamber status (chamber measurements, DUT electrical parameters, alarms and events), for executing the tests...

Personalized solutions The measurement of the performance of a domestic air conditioner must be carried out in accordance with the regulations of the country where the conditioner is to operate. Almost all regulations envisage several methods of energy efficiency measurement which are often very different from one another. Therefore, there are many types of calorimeters, each closer to one method than to another and characterized by specific construction solutions. Calorimeters for domestic air conditioning systems can also be classified according to the power range to be measured, and each category...
