In systems configured to stay above the dew point, the vapour does not condense, which prevents frost formation. However, with medium and low temperature requirements, reaching and exceeding the dew point is more common, increasing the risk of frost formation.<\/p><p>In addition, the thermal gap, defined as the difference between the air inlet temperature and evaporator temperature, directly influences the intensity of dehumidification. A higher thermal gap can lead to more moisture condensing and eventually freezing in the evaporator, as illustrated in the figure. As the thermal jump increases, the amount of absolute humidity that is removed also increases, moving from an initial state point 2a to a more critical state point 2b. This results in a change of the absolute humidity of the air from \u0394w1 to \u0394w2 leading to increased dehumidification.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4c166c4 elementor-widget elementor-widget-image\" data-id=\"4c166c4\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1240\" height=\"683\" src=\"https:\/\/www.intarcon.com\/wp-content\/uploads\/2024\/05\/EN-indluence-thermal-jump-defrost-on-cooling-evaporators.webp\" class=\"attachment-large size-large wp-image-90129\" alt=\"Influence of thermal bridging on defrosting in refrigeration evaporators\" srcset=\"https:\/\/www.intarcon.com\/wp-content\/uploads\/2024\/05\/EN-indluence-thermal-jump-defrost-on-cooling-evaporators.webp 1240w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2024\/05\/EN-indluence-thermal-jump-defrost-on-cooling-evaporators-768x423.webp 768w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2024\/05\/EN-indluence-thermal-jump-defrost-on-cooling-evaporators-640x353.webp 640w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2024\/05\/EN-indluence-thermal-jump-defrost-on-cooling-evaporators-400x220.webp 400w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2024\/05\/EN-indluence-thermal-jump-defrost-on-cooling-evaporators-367x202.webp 367w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2024\/05\/EN-indluence-thermal-jump-defrost-on-cooling-evaporators-600x330.webp 600w\" sizes=\"(max-width: 1240px) 100vw, 1240px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ac3197e elementor-widget elementor-widget-heading\" data-id=\"ac3197e\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Type of refrigerant and phase change slip<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8ecb583 elementor-widget elementor-widget-text-editor\" data-id=\"8ecb583\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Some refrigerants experience what is known as &#8220;slip&#8221; during phase change, which means that the evaporating temperature is not constant throughout the evaporator.
