Climatic chambers - Import export

with adjustable humidity and temperature to simulate the environmental conditions of a test specimen (e.g. household appliances, heating technology) The basis is a standard or climatic chamber (e.g. test kitchen, environmental simulation) with adjustable air humidity and temperature. On the basis of decades of experience in automotive test engineering, EP-E developed a concept in which the air flows in a circle (loop design). The result is a very excellent homogeneous temperature and humidity distribution. Through precise temperature and humidity control, it is possible to set different combinations of air conditioning and thus precisely adjust the required test conditions. The determination of the air flow (exhaust air volume) is carried out via a measuring section with the use of Laminar Flow Elements (LFEs). In order to determine the volume flow, pressure and temperature sensors are used to determine the air volume flow of the climatic chamber(s).

With our HPT heat pump test bench you can simulate humidity as well as temperature. The test stand is used for functional testing of air-to-water heat pumps according to DIN EN 14511. Current test systems on the market, which are used to test e.g. air-to-water heat pumps, are climatic chambers with a cooling, heating and humidification unit fixed to the roof. The disadvantage of this concept is that it is not possible to set a homogeneous temperature and humidity distribution in the cube-shaped room. Based on test engineering concepts in the automotive industry, EP-E developed a concept in which the air flows in a closed loop (loop design). The HPT heat pump test stand is a closed-loop test stand for functional testing of air-to-water heat pumps according to DIN EN 14511. The advantageous closed-loop design uses an insulated chamber with conditioning units for temperature and humidity outside the chamber.
