52016 Overview
-
Calculation methods
-
Hourly
- need..
- H/C load
- Moisture load
- Internal air
- Supply air
Goals:
- variations caused by weather
- modelled element (not parameters)
Approach:
- equation of transient heat transfer
- temp of any element (also air), per hour
- element = nodes of therm capacity and resistance
:check: indoor temp clear
same input that monthly
on/off pattern for shutters & shadings
:green_cross: need software
Output:
- need..
- H/C load
- Moisture load
- Internal air
- Supply air
- Annual under/over-temp
- H/C load in subsystem [W]
- Utilization factor
Comparison:
- same input data
- need to balance outputs
Thermal zoning
-
2) Combine
- Adjacent + same category
- Large opening
- (Adjacent + non-conditioned)
- (Very small)
3) Split:
- Different services
- Different systems
Loops
Output-->Input
- Loads > Recovery
- Indoor air > Supply air
- Indoor moist > Supply moist
- Internal conditions >
shutters/free cooling
About:
- Bld energy needs
- Free-running indoor conditions
- Max power (H, C, de-/Hum) only
