The secondary side of the injection circuit circulates a constant flow through the coil maintaining a uniform temperature throughout the entire coil.<\/p>\n<p>When the control system calls for higher or lower temperature on the air outlet, the PICV valve opens or closes to allow heating or cooling water from the primary side of the injection circuit to enter the secondary side. The temperature in the coil then changes giving an almost direct relation between the temperature in the coil and the power output from the coil.<\/p>\n<p>Benefits<\/p>\n<ul>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0The PICV ensures balancing of the primary flow and eliminates the use of both static balancing valves and differential pressure control valves.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0AHU\u2019s with a large coil area have a uniform temperature in all parts of the coil, providing a precise temperature control.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Direct relation between coil temperature and power output.<\/li>\n<\/ul>\n<p>Considerations<\/p>\n<ul>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Requires a small circulation pump on the secondary side of the injection circuit.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0A metering station can be installed if additional flow verification is required.<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column width=&#8221;7\/12&#8243;][vc_column_text woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;][\/vc_column_text][\/vc_column][vc_column width=&#8221;5\/12&#8243;][vc_column_text woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]Air Handling Unit with PICV injection circuit Function The air temperature of the Air<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[81],"tags":[],"class_list":["post-1310","post","type-post","status-publish","format-standard","hentry","category-applications"],"_links":{"self":[{"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/posts\/1310","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/comments?post=1310"}],"version-history":[{"count":4,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/posts\/1310\/revisions"}],"predecessor-version":[{"id":1336,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/posts\/1310\/revisions\/1336"}],"wp:attachment":[{"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/media?parent=1310"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/categories?post=1310"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/yektatadbirco.ir\/en\/wp-json\/wp\/v2\/tags?post=1310"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
