Rice. 1. Construction on the I-d-diagram of the design mode of operation of the local-central air conditioning system in retail premises during the warm season: H-OH - cooling of the sanorm of the supply air in the central supply unit; OH-PN - heating in the supply fan and air ducts; ПН—В - absorption of moisture releases and part of apparent heat surpluses in the serviced room; В-ВЦпх - cooling of the internal recirculation air at a constant moisture content in the air cooler of the local fan unit; Vmoh-B - the perception of heat release in the room by the air cooled in the local fan unit; В— Vmol — cooling of recirculated air in the local unit while reducing heat generation in the serviced area of the retail space
