Substitute for old technology<\/span><\/h4>\n[\/vc_column_text][divider line_type=”No Line” custom_height=”20″][vc_column_text]Humidity control in air conditioning systems generally uses an evaporator to function to extract moisture from the air. The hot and humid outdoor air through the evaporator will release Sensible Heat, causing the temperature to be lower. If the evaporator has a temperature lower than the dew point, some steam will release latent heat and condense into water droplets. In this case, the dehumidified air is very cold. Overcooled Air is not suitable to pass into the work area. Therefore, it has to use heat from electric coils or steam pipes. Reheating Coil makes the temperature higher to get the air at a comfortable temperature (Comfortable Air) requires high energy to cool the air and hot later as shown in figure.[\/vc_column_text][\/vc_column][vc_column column_padding=”padding-4-percent” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” bg_image_animation=”none”][image_with_animation image_url=”5595″ animation=”Fade In” hover_animation=”none” alignment=”center” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”][\/vc_column][\/vc_row][vc_row type=”full_width_background” full_screen_row_position=”middle” column_margin=”default” equal_height=”yes” content_placement=”middle” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” bg_color=”#ffffff” scene_position=”center” top_padding=”5%” bottom_padding=”5%” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” shape_type=””][vc_column column_padding=”padding-4-percent” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” bg_image_animation=”none”][image_with_animation image_url=”5598″ animation=”Fade In” hover_animation=”none” alignment=”center” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”][\/vc_column][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” bg_image_animation=”none”][vc_column_text]The weather conditions can be shown in the humidity control process in which the evaporator works with the heating coil as shown in the chart.

From the chart it can be seen that in the humidity control by using the cooling coil and the heating coil, the main energy used by the cooling coil (from EA to LA) is used to reduce the temperature of the air to cause condensation of water vapor in the air. The energy is used to increase the temperature of the air after passing through the evaporator (Reheat \u2013 from LA to SA) by using the heating coil to keep the air at an appropriate temperature for further use.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”full_width_background” full_screen_row_position=”middle” column_margin=”default” equal_height=”yes” content_placement=”middle” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” bg_color=”#a8dff3″ scene_position=”center” top_padding=”5%” bottom_padding=”5%” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” shape_type=””][vc_column column_padding=”padding-4-percent” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” bg_image_animation=”none”][vc_column_text]\n

When hot air passes through this heatpipe, they will transfer heat to the heat pipe.

The result is that the wind through this coil will get a temperature of 26.8 \u00b0C near the Dew point, which this process will not reduce humidity at all. (From the P-H Diagram, it can be seen that it is a straight line at 21.53 g\/kg of moisture.) The water that comes out of this coil has a temperature of about 26 \u00b0C (It meets the characteristics of heat exchangers. is the wind coming out of the coil will have the same temperature as the water temperature. But in practice, the wind temperature will be slightly higher because the area will be loaded on the other side as well especially where the Air Handling Unit will supply air due to the motor load.) Then the wind will go through the Pre-Cool Coil, which has water at 7 \u00b0C to raise and exit at 11 \u00b0C. That means that the wind coming out of the coil panel must be higher than 11 \u00b0C, which in the P-H Diagram or the RAC calculation program, the temperature is 12.5 \u00b0C. After that, the wind that passes through the Pre-Cool coil at 12.5\u00b0C will run into the H-RAC coil, which has water supplied from C-RAC at a temperature of 26 \u00b0C to supply. As a result, the wind coming out of this coil panel has a temperature of 20.7 \u00b0C at a humidity of 9.064 g\/kg and a relative humidity of 59.36 %RH, and the water exiting the H-RAC coil panel has a temperature of 20 \u00b0C and pass through the C-RAC coil panel.[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"
