This gas undergoes thousands of cycles of compression and expansion to lower the air temperature in the car.[\/vc_column_text][vc_column_text]In order to do so, some key elements are requested. A <strong class=\"d2b\">car air conditioning system<\/strong> works according to the following principle:<\/p>\n<ul>\n<li>A <strong>compressor<\/strong> compresses the refrigerant gas. The refrigerant, whose pressure has been high, becomes hot.<\/li>\n<li>The <strong>condenser<\/strong> is therefore supplied with high-pressure hot refrigerant gas.The refrigerant gas compresses itself by passing through the condenser (becomes liquid at constant pressure) and cools itself down with the flow of external air forced by an electric fan.<\/li>\n<li>The liquid cooling gas goes through a<strong> regulator<\/strong> which sharply lowers the pressure to 2 bar, more or less.Part of the cooling liquid vaporizes, resulting in a decrease in the temperature of the cooling liquid.<\/li>\n<li>As it goes through the <strong>evaporator,<\/strong> hot air ends up vaporizing the liquid part of the refrigerant causing air cooling (from which is extracted a great part of its moisture which condenses on the evaporator). This cold air is then injected into the system and the refrigerant gas returns to the compressor for a new cycle.<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;800&#8243; alignment=&#8221;center&#8221; onclick=&#8221;link_image&#8221;][vc_empty_space][vc_single_image image=&#8221;2695&#8243; alignment=&#8221;center&#8221; onclick=&#8221;link_image&#8221; css_animation=&#8221;fadeIn&#8221;][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]In order to ensure the <strong class=\"d2b\">tightness of evaporators and condensers<\/strong>, first level <strong class=\"d2b\">automotive suppliers<\/strong> have relied on our know-how in the field of <strong>leak detection with Helium and H2 tracer gases, <\/strong>for more than 25 years.<\/p>\n<p><span class=\"fort\">Alliance Concept<\/span> is a French manufacturer of <strong class=\"d2b\">Helium, H2 leak detection equipment<\/strong>.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;1717&#8243; alignment=&#8221;center&#8221; onclick=&#8221;link_image&#8221;][\/vc_column][vc_column width=&#8221;2\/3&#8243;][vc_column_text]This <strong class=\"d2b\">semi-automated single station detection equipment<\/strong> has been developed to meet ergonomic requirements and an industrial logic, ie : to produce efficiently, with an optimized cycle time, at a high production rate.<\/p>\n<p><strong class=\"d2b\">Condensers<\/strong> or <strong class=\"d2b\">evaporators<\/strong> are globally <strong class=\"d2b\">detected under vacuum<\/strong>.
