An ideal heat pump system was optimized by considering the coefficient of performance and the size of condenser and evaporator as two competing objectives. Thermodynamic limitations were included as natural constraints. Experimental data for compressor performance were utilized in evaluating the system behavior. With a varying weighting factor between the two competing objectives the optimum deiogn parameters were presented in a graphical form.

For a periodic variation of the flue gas temperature the heat conduction through the Ondol floor was analysized. Also the heat loss to the ground was estimated. The floor thermal capacity, as a function of the floor thickness, has strong influence on the time lag of the temperature variation. It is an important design parameter for intermittent heating. Even for the steady periodic variation, there was significant heat loss to the ground below the Ondol floor.

A simple analysis has been made of the condensation of vapor onto rivulets of condensate which are formed by non-wetting narrow Taflon strips circumferencially located in a certain interval on horizontal tubes. Heat transfer to the rivulets increased over $50\%$ above that to the Nusselt uniform thickness film. Results are directly applicable to condenser tubes in large steam condensers.
