Abstract: This study deals with the study and calculation of the thermal conductivity of the tube solar collector with heat pump. The basic equations describing the energy balance of the flat solar collector with the heat pump. This study discusses the calculation of the amount of heat in the heat pump in the combined system of solar heating. A heat balance equation of the heat pump in the integrated system of solar heating method for computing was developed using the techniques above, determine the amount of heat and energy balance equation. The results show that the arrangement of the compressor in the evaporator zone of impact. The evaporator absorbs the heat emitted from the surface of the compressor which is added to the main flow. In view of the fact that the temperature difference between the compressor stack (about 800°C) and the evaporator (about 180°C) is 600°C strand it suggests that the main flow is radioactive heat transfer between the surfaces. As is known in the heat radiation is eliminated between the compressor and the evaporator by setting the screen there between. Accordingly, there has been some decrease in performance. However, even under these conditions the compressor does not overheat because its convective cooling is maintained. Energy conversion efficiency (KPI) are from 2.5-4.5 units.
