Optionally, solar heating may be specified for the. RESYS system. Note:If solar heating is specified (HEAT-SOURCE ~ HOT-WATER/SOLAR), a differentphilosophy is involved. While the cooling system will be simulated here inSYSTEMS, the heating system simulation will be accomplished entirely in thesubsequent PLANT run, because the solar heating demand must be passed fromSYSTEMS to the Solar Simulator (CBS) in PLANT. In CBS the user may select anypreassembled residential system or user-assembled residential system.Additionally, the user may assemble his own solar-assisted heat pump system.The heating demand not met by the solar system will then be satisfied by aconventional furnace that must be specified in PLANT. The unsatisfied loadcannot be passed back to SYSTEMS. See Chap. V., Sec. C. for other equipmentcombinations that are avail ab leoIf solar heating is not chosen, the heating load will be met here inSYSTEMS and a utility loaa-will be passed to PLANT.Table IV.20 shows the commands and keywords that must be entered forsimulation of this system, as well as those that are applicable but optional(i .e., program uses default value if entry is omitted).A multizone residential system may be modeled with the RESYS systemtype. The first zone listed under ZONE-NAMES is assumed to have thethermostat and to control the system. The subzones receive air at the timesand at the temperature as determined by the thermostat action in the controlzone.I V.84 (Revised 5/81)
