Research into energy efficiency of the underfloor heating system, assembled dry
Journal Title: Технологический аудит и резервы производства - Year 2018, Vol 3, Issue 1
Abstract
<p><em>The object of research is the thermal parameters of operation of a fragment of the floor heating system assembled dry, under conditions of actual application set in the lab premises. </em></p><p><em>One of the most problematic issues in the course of our experimental study has turned out to be a small area of the investigated heating system, relative to the volume of the room. Considerable ambient air temperature fluctuations resulted in certain difficulties while the heating system entered the quasi-steady mode.</em></p><p><em>We have established in our study the effect of thickness of a heat insulation layer under the heating circuit on a change in the density of heat flow from the floor surface to the air in a heated room. It is noted that the floor heating system, assembled dry, has small thermal inertia due to the absence of a relatively thick layer of the monolithic concrete slab (with high specific heat capacity), which is typically used for the installation of a heating system circuit.</em></p><p><em>Specifically, it was established that the use of ceramic tiles as the finish coating, compared with laminate, significantly reduces the overall thermal resistance of heat transfer from a heat carrier to the air in a heated room. In this case, the presence of an aluminum heat-scattering plate, which is in direct contact with the outer surface of the pipe in a heating circuit, has a positive effect on the uniformity of distribution of thermal field in the plane of the floor. This in turn leads to a reduction in thermal stresses in the finish coating.</em></p><p><em>Calculations show that the quantitative control over thermal load of such a system by changing the consumption of a heat carrier proves to be less effective than the qualitative control through changing its temperature. </em></p><p><em>Experimental studies reveal that the density of a heat flow on the floor surface increases almost two-fold when using ceramic tiles, in comparison with laminate, at all other thermal system settings being almost identical.</em></p><p><em>The research we conducted make it possible to construct a mathematical model for the operation of a floor heating system, assembled dry, whose application would enable the optimization calculations and improvement of the design of a given heater. </em></p>
