Application of refrigerant cooling for air conditioning of buildings
Vlček, Petr ; Rubina, Aleš (advisor)
Diploma thesis deals with the problem of refrigerant cooling needs for air conditioning systems of buildings. Summary focuses on the theoretical basics and the physical nature of refrigeration and air conditioning technology. The consequences of split unite on microclimate in the room was experimentally tested and simultaneously investigated happenings associated to its activity. The aim is to unify the theoretical and experimentally obtained facts and apply them in the designing of air conditioning units. Design of air conditioning systems builds on my bachelor thesis, "Hot-air heating of gym", which subject was the ventilation system of gym.
