Heating House Model

The model of the heated house was designed and built as part of Absolvent thesis by Petr Rabiňák at the higher vocational school in the school year 2013/2014. The model represents the thermal processes of real buildings (heat transfer through the wall and heat accumulation in the wall), domestic heating, etc. The model is connected to the computer by a multifunctional input/output card allowing reading outputs and setting inputs. The resources of the school were used to implement this teaching aid. The cost of the components was 7 984 CZK. The implementation took 541 hours.

Interface inputs and outputs

Inputs: voltage on the heating elements in the right and left rooms u_l, u_r [V], cooling unit voltage u_ac [V], ambient temperature T_out [°C]
Outputs: air temperature in the right and left room T_ar, T_al [°C], temperature in the walls of the right and left room T_wr, T_wl [°C]

Used for teaching:

SS: verification of the laws of thermal processes (heat transfer through the wall)
SS: measurement of the static transfer characteristics of the sensor
TTS: modelling and identification of dynamic systems
TTS: temperature control in one or both rooms with a PID controller

Temperature Sensor Kit

In December 2025, based on anbsp;suggestion from the ET3 class, Jirka Roubal designed a teaching aid with temperature sensors (Ni1000, a thermocouple and PTC and NTC thermistors), see Figure 2. Mr. Ťoupal and the students of the MP3 class milled an aluminum plate, see Figure 2a, Pavel Kavan prepared the front panel of this aid, see Figure 2b.
