Question

(1) Single Loop HVAC system: A space is to be maintained at 75 °FDB and 50 % relative humidity Outdoor air is at 95 °FDB and 60 % relative humidity. Mark these psychrometric states on a psych chart clearly with small circles labeled RA and OA. The space has a heat load of 100,000 BTU/hr and a moisture gain of 30 lbm-whr. Assume that the enthalpy of this moisture is 1100 BTU/lbm-w. Determine the values indicated below, and fill in the blanks or the following table: Sensible Heat Load BTU/hr Latent Load BTU/hr The psychrometric slope EHR and humidification process Ah AW for the space condition line or space load e for this heating BTU/1bm-w

    Example: The sensible- and latent-heat gains in a space served by a single-zone air conditioner are 65 and 8 kW, respectively. The space is to be maintained at 24 oC and 50% relative humidity. The design conditions of outdoor air are 35 oC dry-bulb and 25 oC wet-bulb temperatures. For ventilation purposes outdoor air is mixed with recirculated air in a 1:4 proportion. When mixed air at the resulting conditions enters the cooling coil, the outlet air conditions are 12...
