Gas heat pumps based on stroke engine
Bedřich, Miroslav ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
The aim of this Diploma thesis is a description of gas heat pump (GHP) technology and the possibility of their usage in real life. Also units from the major manufactures of GHP units in the Czech Republic and abroad are evaluated from technical and economical point of view. The thesis as well includes a part where is decided if it is better to further develop GHP units with higher or lower performance. In the last part of thesis are cooling circuits designed for both lower and higher performance, than performance of existing GHP unit Polo 100. As a result, the units with higher performance are more perspective. Therefore heat plate exchangers, which serve as a condenser and an evaporator, are designed for unit with higher performance.

Condensation heat exchanger beyond CHP unit
Sojka, Jiří ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The aim of this thesis is to design the condensation heat exchanger for stationary engine running on natural gas. Flue gas condenser is designed for universal use of refrigerants (i.e. water or 35% fusion ethylene-glycol in water) and their working temperatures. The work includes theoretical, computational and design part. In the attachment is located the drawing documentation to flue gas condenser.

Gas heat pump
Krejsa, Petr ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis deals with the description of heat pump technology (HP) and the gas heat pumps extension (GHP). The theoretical part contains an introduction, information of heat pump technology, presentation of gas heat pump technology powered by a natural gas combustion engine. The comparison of the known principal design is involved too. The calculation part deals with detailed balance of energy flows for the specific operating conditions of GHP unit. The last part compares the electrical and gas heat pump.
