Net values at Eurovent nominal conditions : YMWA-CO : Standard Eurovent LCP / W / AC conditions in cooling mode : evaporator EWT / LWT 12 ° C / 7 ° C , condenser EWT / LWT 30 ° C / 35 ° C YMRA : Evaporator EWT / LWT 12 ° C / 7 ° C , condensing temperature 40 ° C YMWA-HP : Standard Eurovent LCP / W / AC conditions in cooling mode : evaporator EWT / LWT 12 ° C / 7 ° C , condenser EWT / LWT 30 ° C / 35 ° C YMWA-HP : Standard Eurovent LCP / W / AC conditions in heating mode : evaporator EWT / LWT 10 ° C / 7 ° C , condenser EWT / LWT 40 ° C / 45 ° C Ecodesign figures are calculated following fixed water and variable outlet approach ( FW / VO ). For other Ecodesign calculations , please contact your JCI representative . SEER and SCOP calculated according to EN14511 and EN14825 ηs calculated according to Ecodesign regulation for chillers comfort cooling and heating ( 813 / 2013 , 2016 / 2281 ). The above data is based on Johnson Controls ’ selection software YORKworks 20.05b . Please refer to the latest version of the software for specific projects
