The web application is designed to fully adjust the geometric parameters of a cold room. It can handle square-, rectangular- and L-shaped cold rooms too. Insulation parameters for each side of the room can be entered separately, e.g. thickness of insulation, type of insulation (unique K values can be entered too), outside temperature of a particular side. The app contains the data of 160 refrigerated goods. Other heat load factors during cooling and freezing can also be entered in detail like the number of persons and heat emitting devices, duration of their stay and operation, heat load of illumination. Based on the entered data the app calculates the total cooling heat load and prepares a detailed tracking of the partial loads such as persons, illumination, devices, ventilation, evaporator fan, defrosting, goods and insulation load. Downloadable and printable pdf documents can be created from the calculations. The pdf document may contain not only the data and the detailed results of the calculations but the data of its maker as well. The calculation can be saved in the web application. It is stored on our server and not on your computer which ensures easy access from anywhere at any time, quick loading and instant use.
