Analysis of heat pump integration into drying process …

drying process accounts for 10–25 % of total industrial energy consumption in most developed countries. Currently, however, waste heat recovery from drying process is still limited to air preheating by heat exchangers. Heat pump can valorize more waste heat and lift up the decreased temperature to the tem-perature required by the drying process.

1 Fundamentals of Energy Analysis of Dryers

1) Thermal inefficiencies in the dryer: exhaust heat content in convective dryers, sensible heating of solids, heat losses from dryer body. 2) Thermal inefficiencies in the utility (heat supply) system: steam generation efficiency, steam leaks and mains losses. 3) Additional energy demands: power for solids transport, vacuum pumps and air fans.

A Review of Drying Theory and Modelling Approaches

Drying of building material has a long history since it has been found very long ago that drying could be used to convert clay into a useful building material. Drying processes are still nowadays an important step in the processing of building materials. Related to drying evaporation from building material is also an important topic in relation ...

Development and optimization of highly efficient heat …

A heat wheel with the counterflow airflow arrangement has theoretically a relatively high efficiency. However, field measurements of heat wheels in buildings have shown that the actual efficiency can be dramatically lower than designed or predicted [17], [18].There are different reasons for the unexpectedly low efficiency: 1) longitudinal heat conduction along with …

Phase change with inner ventilation for energy management: …

1. Introduction. Energy consumption in buildings contributes to more than 30 % of the total energy consumption in our society [1] and the same is projected to grow significantly in the future [2].The resulting increase in demand for energy may therefore have detrimental effects on climate change and carbon-dioxide emissions [3], which in turn may adversely influence the …

The Basics of Heat and How It Is Utilized in Drying, For …

Imagine the heat produced of a typical dry-out being 10 fans, a dehumidifier and an air scrubber; this common drying equipment creates its own heat/energy naturally. Enthalpy The enthalpy of moist air includes both the heat absorption capacity of the dry air, called sensible heat, and the capacity of the evaporated water in the air called ...

Temperatures for drying buildings | CityCool Ireland

The higher the temperature, the shorter the drying time. An extra source of heating should be used when drying buildings. This is vital when the temperature is circa 10ºC, as the air cannot contain any moisture as these temperatures. Expert tip: When dehumidifiers are used in conjunction with heaters, don't locate them too close to each other or the dehumidifier will only …

Design and Operate a Small-Scale Dehumidification Kiln

This gives me a secondary method of tracking the drying process, using both water volume and moisture content (MC) readings. A small electric heater supplies auxiliary heat to maintain adequate kiln temperature. In smaller kilns, the heat generated by the fans and DH motor is sufficient to maintain temperatures in excess of 100 degrees.
