Air Handling Units for Carrier and with his great, knowledge and experience serves market most reliably. 2 2 STanDarDS, There are two European standards on air handling A model box is an air handling unit without its installed. units that describe the characteristics of the casing wall components that consists of two sections with a joint. construction and the classification and performances of Each section also has a door The dimensions and the. units components and sections respectively construction must comply with the requirements of. en 1886 1998 the standard,Air handling units Mechanical performance.
en 13053 2001 Thermal and acoustic characteristics of a casing wall. Air handling units Ratings and performance for construction are exclusively determined on the basis of. units components and sections measurements taken on the model box while. Both standards have been revised and now also exist mechani cal strength air leakage and filter bypass. as a prEN standard leakage must be determined on the basis of. measurements taken on a real unit that has been, The characteristics of the casing wall construction designed for an HVAC application The classes for the. must be established in accordance with EN 1886 last three characteristics may also be determined for a. based on measurements carried out on a model box model box if this is clearly indicated. and a real unit,2 1 Mechanical strength, There are two test criteria for mechanical strength. relative deflection mm x m 1 of posts and panels under normal design conditions. mechanical resistance no permanent deformation against maximal fan pressure. When testing the mechanical strength of the model box the following test pressures apply. deflection 1500 Pa over and under pressure in accordance with EN 1886 1998. 1000 Pa over and under pressure in accordance with prEN 1886. Fan pressure 2500 Pa over and under pressure in accordance with EN 1886 1998. 2500 Pa over and under pressure in accordance with prEN 1886. The standard differentiates between the following classes.

The unfiltered air flow is the sum of section and filters are sometimes replaced by dummy. air that passes the filter medium outside the filter plates with an air tightness mechanism identical to. section the one of the filters, air leakage through the walls of the sections after The tables below list the total admissible bypass leakage. the filter with negative pressure k in of the design air flow over the filters as a. function of the built in filter class, Maximum admissible filter bypass leakage in accordance with en 1886 1998.

The standard slide in construction for filters tested in a model box is suitable for filter class F9 if marked in blue. in the tables In accordance with standard prEN 1886 this is based on a face velocity of 2 5 m s over the filter 7. e g 0 93 m3 s for a 610 x 610 mm filter,2 2 4 Thermal transmission. The thermal transmission of a model box is the average outside is determined at a stable condition. heat transfer coefficient of the construction in W x m Thermal transmission is the ratio between the total. x K 1 referred to the external surface power input and the internal external surface. The measurement is carried out with heat sources in temperatures times their surface area Depending on. the model box where the total power input and the the measured values the construction has in one of. average temperature difference between inside and the following classes.
