Temperature sensor Heating element Revolving shutter Exhaust pipe Fig. 20: Diagram of condensing chamber Global Journal of Researches in Engineering 34 Year 2019 © 2019 Global Journals This diagram is differed from the diagram, depicted in Fig. 3, by the presence of heat exchanger in the lower part of the ventilator section (it is shown by fatty cross). With the work in the condensational regime in the lath, located under the engine (Fig.4) all openings are stopped, and sucking into the camera of atmospheric air ceases. If we through the heat exchanger pass cold water, then on it will be condensed water, which will flow through the exhaust pipe. The application of this diagram of drying with the presence of the artesian well, where the temperature of water is about 9 0 C and practically does not change during the year, is especially rational. For purposes cooling heat exchanger it is possible to use tap water. With a difference in temperatures in 20 degrees between the water, which enters the heat exchanger and the water, which escapes from exhaust pipe, for the drying 1 m 3 of wood be required ~ 10000 kg of water. The regime indicated to rationally use, when wood moisture content is not lower than 15% and the humidity of air in the camera is relatively high. With the values of wood moisture content of lower than the value indicated should be switched the camera to the cyclic regime, examined above. Application of the regime examined gives to 25% of savings according to the expenditure of electric power. As the heating elements in the camera can be used both the batteries, fed from the gas hot-water boiler and electric heater. In the water outline of this boiler it must they stand the pump, which must be included according to the same diagram as electric heater. In this case is used the diagram of the electric power supply of camera, depicted in Fig. 19 with the only difference that instead electric heateris connected the electric motor of pump. With the use of hot-water boiler it is necessary to reduce the temperature of the drying of softwood to 80 0 C, since. With the use of higher temperatures the effectiveness of the use of hot- water boiler is strongly reduced because of by the small difference between the temperature in the camera and the temperature of water. With the work with the hot- water boiler the surface of batteries must be ~ 15 m 2 , while with the use electric heater their surface it is ~ 1 m 2 . This a difference in temperatures between air in the camera and surfaces of batteries and electric heater connected with the fact that differs approximately 15 times.

Application Adaptation for cutting the foam plastic The schematic of adaptation for cutting the foam plastic is shown in the figure. to the working table to the hinge is fastened the board, on which are located two metallic pintles. The Nichrome wire with a thickness of 0.5 mm. is extended between the ends of these pintles. So that with the heating the wire would not sag, spring is used. To the wire through the step-down transformer brings the stress, which is selected in such a way that the heated wire would rapidly melt foam plastic.
